Keto angel food cake can be a little intimidating at first. Even though there are only 6 ingredients (plus one optional one and salt), it can be a a little finicky and has a specific process to follow. Don’t give up on it, though… I promise that this low carb angel food cake recipe is worth the effort!
And, it’s not actually that time consuming for a cake – you just need the right technique. In this post, I’m sharing all the tips to ensure that your almond flour angel food cake turns out perfect each and every time.
This sugar-free, gluten-free angel food cake is great on its own, but it’s also delicious with some keto whipped cream or berries.
Bonus: each slice has just 84 calories and 2g net carbs. And you’d never know it. 😉
What Is Angel Food Cake?
Angel food cake is a light and airy vanilla sponge cake. Traditionally, it’s made with egg whites, flour, and sugar, and most notably, no butter or fat added.
To make a keto friendly angel food cake, we’re making this recipe an angel food cake made with super fine blanched almond flour, coconut flour, and powdered monk fruit sweetener.
How To Make Angel Food Cake (Keto Friendly)
This keto angel food cake recipe isn’t hard to make, but it does have a few precise steps to follow. Look at the step-by-step pictures, but also check my tips below this section, to ensure you get perfect angel food cake every time!
- Prep your pan. Line the bottom of a 9.5-inch tube pan with parchment paper, but don’t grease it! Make sure your pan and all utensils have no grease as well.
How to cut parchment paper for lining the pan: Flip your pan over and cut a circle along the edge. Then, fold the circle in half and cut a small semi-circle in the center, matching the size of the center column. Unfold, flip the pan over, and place your parchment paper inside.
- Whip egg whites until frothy. In a large, deep bowl, use a hand mixer with whisk attachment to whip egg whites and cream of tartar together, just until frothy.
- Add Besti and beat to soft peaks. Once the egg whites are frothy, increase the speed to medium high and gradually add powdered Besti. Beat until soft peaks form (not stiff peaks!). Soft peaks will create the most lift and rising in the oven.
TIP #1: Be sure to use a large bowl, because the whites will triple in volume (or more). They are done when you see soft trails like this:
TIP #2: Soft peaks look like the picture below. They have some structure, but curve over when held vertically. Be careful not to overmix!
- Mix keto angel cake dry ingredients. In a medium bowl, whisk together almond flour, coconut flour, xanthan gum, sea salt, and more powdered Besti. Make sure there are no lumps.
- Sift and fold in dry ingredients. Sift half of the flour mixture over the egg whites through a fine mesh sieve…
… And fold in using a rubber spatula. Do this in batches and fold very gently, until just incorporated.
TIP: Be careful not to deflate the whites. When you add the flour mixture, sift it in gradually, a little at a time, and gently fold. Don’t stir or dump the ingredients on top, which would cause the whites to deflate.
- Transfer to tube pan. Gently scoop the almond flour angel food cake batter into the pan, again being careful not to break down the whites. Smooth the top with a spatula.
- Bake. Your low carb angel food cake is done when the top is golden and springs back when touched lightly. Be sure to cool it correctly when done – see instructions below.
TIP: Do NOT use the toothpick test! Sometimes, it slides through the batter and comes out clean even if the cake is not done. Visually, the angel food cake will look like the picture below when done.
How to Cool Almond Flour Angel Food Cake
There is a special method to cooling almond flour angel food cake, and it’s important! Here are the 2 critical components:
- Cool the low carb angel food cake upside down. For best results, it should have air flow underneath as well.
- You must flip it immediately after removing from the oven, or it will fall within minutes.
Why do you have to cool angel food cake upside down?
While the cake is still warm, the spongy texture has not fully set. If you don’t cool it upside down, your keto angel food cake will collapse under its own weight.
How to cool angel food cake upside down:
There are 3 ways to cool your keto angel food cake upside down:
- On a bottle – This is the oldest trick. Simply place the neck of a study glass bottle into the hole in the center of the tube pan, then invert, so that the bottle stands upright and the tube pan is upside down on it, floating with air flow underneath.
- On a wire rack – Place inverted pan over wire rack to cool. The downside is that if your cake is overflowing, you might leave marks from the rack on top.
- Use a pan with feet – Special tube pans have feet that lift up the pan off the counter. This is the method I use – I love this pan with feet, pictured below.
How to release angel food cake:
Let your cake cool completely first, upside down as shown above. Once it’s completely room temperature:
- Run a knife along the edges. Make sure to get the outer edge and especially the winner edge – this part is most prone to sticking.
- Flip the cake over a cake stand or large platter. I like to gently support the open side with my hand in case it falls abruptly.
- Lift the sides of the pan first, then lift the bottom of the pan. This is why a two-piece pan comes in handy!
- Gently peel away the parchment paper. The parchment used to line the pan will be stuck to the cake, so just gently peel it off.
- Flip cake again if desired (optional). Place another plate or platter over the top of the cake, then flip the two plates or platters together in a quick motion, so that the bottom is on top.
I’ll let you in on a secret – I forgot step 5 for my pictures in this post. Notice how the top is pretty straight, not puffed up? That’s the reason. You can see the puffed up side of the cake in the slice below – ideally, this would be the top of your cake.
Important Tips For The Best Keto Angel Food Cake
Like I mentioned, angel food cake isn’t hard, but it does require a few things to turn out properly.
Here are all my tips to ensure that your keto angel food cake turns out perfectly each and every time – some of these repeat from above, because they are so important!
- Use a tube pan. It’s important to use a tube pan and not a bundt pan. While they seem similar, the tube pan gives the cake the structure it needs.
- Line the bottom but don’t grease the pan. It’s important to avoid greasing any pans or utensils when making angel food cake – otherwise your angel food cake can fall. Lining the bottom of the pan helps release the cake later.
- Use room temperature egg whites. Cold whites won’t whip very well or hold as much air. If your eggs are straight from the fridge, you can place them in warm water to bring them to room temperature before separating the whites from the yolks.
- Use fresh egg whites from whole eggs if at all possible. Carton egg whites do work, but they won’t create quite as much air, so your cake may be a bit more dense.
- Be careful separating egg whites. Make sure even the tiniest bit of yolk doesn’t get in with the whites, or they will not form peaks.
- Beat egg whites to soft peaks, not more or less. See the pictures above for cues that they are done – soft trails in the whites and peaks curl over when held upright. Under-beating will result in a cake that has no lift, but over-beating can make it too dense as well. Avoid stiff peaks!
- Sift in the flour mixture. If you just dump it in, the whites will deflate. You could use a special sifter, but a fine mesh sieve works just as well.
- Do not stir the batter. Again, we’re trying to avoid deflating the whites. Use a folding motion from underneath instead.
- If you use a 2-piece pan, pick it up by the edges, not the bottom. If you push on the bottom, it will separate and the batter will leak.
- Do not check on your cake in the oven. I know it’s tempting, but resist the urge to check! You can get away with maybe checking once toward the end (and open just a crack!), but otherwise keep that door shut. Even the slightest temperature change from opening the door can cause the cake to fall.
- Test for doneness visually and by touch, not toothpick. As mentioned above, the toothpick test can be deceiving. It’s done when it’s golden and springy to the touch.
- Flip the cake over immediately and quickly to cool. The cake can deflate within minutes after coming out of the oven if kept right side up, so flip it upside down instantly – see the 3 options above for cooling it upside down. This is the most critical part!
- Slice angel food cake using a serrated knife. A chef’s knife is more likely to crush it.
Low Carb Angel Food Cake FAQs
Can you have angel food cake on a keto diet?
While angel food cake is known as a light cake, it’s still typically made with white sugar and flour. This easy low carb angel food cake is made with Besti, almond flour, and coconut flour, so it’s perfect for low carb and keto lifestyles.
Is low carb angel food cake dairy free?
Yes, this cake is naturally dairy-free.
How many carbohydrates in angel food cake?
Each slice of almond flour angel food cake has just 2 grams net carbs!
Why did my angel food cake fall?
Angel food cake can fall for several reasons. Specifically, it may be due to deflating egg whites when making the batter, over- or under-baking the cake, not flipping it over quickly enough after baking, or not cooling upside down at all.
Check my tips above to ensure that your keto angel food cake won’t fall!
Why is my angel food cake dense?
This can happen if your egg whites were not the right consistency of soft peaks. See the pictures above for how they should look. If they are too watery or too stiff, your cake can be dense.
Another reason it might be dense is if you don’t sift the flour mixture or deflate the whites when folding it in.
Can I omit the almond flour or the coconut flour?
No, I don’t recommend it. The proportions of the ingredients in this recipe are pretty precise, and does not yield well to substitutions. I did try a couple versions with only almond and only coconut flour, and both had texture issues.
If you want an almond flour cake, try almond flour pound cake or French almond cake. Find more almond flour recipes here.
If you want a coconut flour treat, try coconut flour cookies or coconut flour muffins. Find more coconut flour recipes here.
Can I use a different sweetener?
Possibly. I used powdered monk fruit allulose blend, but crystallized monk fruit allulose blend should work okay as well.
I don’t recommend other granulated sweeteners, because they don’t dissolve as well and keto angel food cake is so light that you might end up with a gritty texture.
Powdered monk fruit with erythritol or plain powdered erythritol might work, but you might notice a cooling effect.
Can you make it ahead?
Yes, you can make this low carb angel food cake recipe ahead as it will need time to cool properly.
How to store angel food cake
Store this almond flour angel food cake in an airtight container for 2-3 days in the pantry. It will last up to a week in he fridge, but may collect extra moisture.
Can you freeze gluten free sugar free angel food cake?
Yes, you can freeze angel food cake. I prefer to slice the cake, then wrap slices individually in plastic wrap. When you’re ready for a slice, take it out and let it thaw.

Preheat the oven to 325 degrees F (162 degrees C). Line the bottom of a 9.5-inch tube pan with parchment paper. (Don’t grease it!)
In a large, deep bowl, use a hand mixer with a whisk attachment to whip egg whites and cream of tartar together.
Start on medium-low speed for 1-2 minutes. Once frothy, increase speed to medium high and gradually add 3/4 cup (108 g) powdered Besti. Continue to beat until soft peaks form (they should curl over but not be stiff). Beat in vanilla extract, until just combined. (Do not over mix - avoid stiff peaks.)
In a medium bowl, whisk together the almond flour, coconut flour, xanthan gum, sea salt, and remaining 3/4 cup (108 g) powdered Besti, making sure there are no lumps. (If the mixture is still lumpy, you can sift over another bowl through a fine mesh strainer.) Sift half the flour mixture over the egg whites, then fold gently just until incorporated, being careful not to break down the whites. Repeat with the remaining flour mixture.
Transfer the batter to the lined (ungreased) tube pan. Smooth the top with a spatula.
Bake for about 45 minutes, until golden and springy to the touch.
Take the cake out and immediately turn the pan upside down to cool (with the bottom of the pan upward), making sure there is air flow underneath the cake. You can accomplish this by using a pan with feet, using the bottle method, or simply a cooling rack (more details in the post above).
Once the cake is completely cool, run a knife along the edges of the pan to release, then invert the cake. Gently peel off the parchment paper on top. If you prefer, you can flip the cake again, or just leave it as is.

This was wonderful, absolutely perfect!
I Changed out the almond flour for carbquik added 1 Tlb. Protein.
Thank you 😊
Can allulose be substituted?
Wholesome Yum D0
Hi, The Besti Monkfruit Alluose Blend will provide the best results for this recipe. If you don’t have Besti on hand, you can use my Keto Sweetener Conversion Chart to find an alternative.
I’m a pastry chef and this was a flop! The flavor was good, but it was heavy as a rock😞

Hi Konnie, Sorry this recipe didn’t meet your expectations. Did you follow the recipe as written?
My immersion blender didn’t come with a whisk attachment and I think I lost that attachment for my mixer. Can this be whipped by hand or won’t peaks form?
Maya | Wholesome Yum0
Hi Carrie, It would be pretty difficult by hand. If you can’t find the whisk attachment, I would try it with the beater attachments. It will take a bit longer, but still much faster and easier than trying to do it by hand.
A fantastic keto angel food cake with NO Erythritol. I have so much trouble digesting it and was glad to find a recipe without it. This cake is delicious and so easy to make! It’s much softer, fluffier, and has more moisture than most keto cakes. I have a 10″ pan and baked 40 minutes instead of 45, but followed the recipe exactly as written. I made it for July 4th and served with a few strawberries and keto vanilla bean ice cream. Everyone raved about it! Next time I might add some almond extract as one reviewer did, but I know I’ll definitely make this cake again and again!
Made this cake today and it was delicious! I followed the recipe exactly but added 1/4 tsp of almond extract and used Lakanto Monk Fruit Baking Sweetener. I used the recommended tube pan and lined it with parchment paper. My oven is an electric oven and I find when baking, I have to add 10-15 minutes to the recommended baking time. I let this one bake for 60 minutes and it looked just like the picture. Once it was totally cooled (inverted the tube pan as recommended), I cut around the outer and inner edges, flipped it and it came right out. I cut a piece right away and when I tell you this cake tastes better than any ‘regular’ angel food cake! It was so moist! It’s so good by itself but I’m going to make some keto whipped cream tomorrow to go along with the blackberries and raspberries I have in my fridge. I can’t wait! Thanks for this amazing recipe!
Just made this tonight and wow! So fluffy and tasty! Will be saving this recipe to use again! Thank you!!!
Great recipe! My cake turned out perfectly. I didn’t put any wax paper on the bottom of my pan (I have the same pan with feet) – I just cut it out at the end. I love how healthy this cake is since there’s no butter or cream in it.
Can I always use powdered Stevia instead of erythritol or other products in all your recipes? I live in UK and some things aren’t available here. Monkfruit is not an ingredient we have so is Stevia a replacement for that and if so in what quantities? Your recipes look delicious, I can’t wait to try them. On Keto but so hard. Is there a conversion chart for American cups? Preferably in ounces or grams – cups can be any size so quantity is vital to the outcome of the recipe. Also, lots of recipes are microwaved – eg mug cakes, quick bread in ramekin dishes. I don’t own a microwave so can I use it in a conventional oven and if so at what Gas setting, please. Are all your recipes Keto or are the low carb ones not suitable? Keto can’t eat bananas, apples, oranges, pears, plums etc – only berries. Can’t eat any pulses, rice, potato, sweet potato, pasta, and grains. Thank you for your help.
Wholesome Yum D0
Hi Majorie, You can find my keto sweetener conversion chart here. In most of my recipes I give a microwave alternative. All of my recipes are keto and low carb. It is a personal preference of how many carbs you want to consume every day.
I made this cake this morning with my 8yr old Granddaughter, I was a little leery as I am new to “Alternative” baking, but I have been missing having something sweet since giving up sugar and wheat flour no longer likes me. I am no longer leery of trying new recipes, this cake turned out fabulous!! I served with sliced strawberries, sweetened with Stevia and Monk fruit. The whole family thought it was delicious!!! I look forward to trying the Chocolate Cake.
I just took this out of the pan and it came out beautiful! I, of course had to taste test it and WOW! it’s delicious. Thank you for sharing this great recipe.
Would a silicone angel food cake pan work to bake this in? Really want to try this recipe. Thanks
Wholesome Yum M0
Hi Sharon, You want the cake to stick to the sides of the pan so you can flip it upside down to cool, so a silicone pan is probably not the best choice.
If I use granulated monk fruit do I use the same measurements as powdered? Also, I hope it’s ok I am cutting the recipe in half.
Wholesome Yum M0
Hi Krystal, I do not recommend making this recipe with granulated sweetener, you will not get the correct texture and your cake will likely be gritty.
Can you use egg whites from a carton?
Wholesome Yum M0
Hi Estephany, Yes, but be sure to use a fresh carton.
I used parchment paper and allowed it to cool. After scribing around the edges and tube middle, it still didn’t come out. Later I went around the edges again and it only half came out and the other half still was stuck on the bottom. It also didn’t raise like a regular angel food cake. The flavor is good, and I will still use it, but for the work and the number of eggs I sacrificed, I won’t try this again.
Wholesome Yum M0
Hi Carole, I do recommend lining the bottom of your pan with parchment to prevent sticking. Ideally, the cake will adhere to the sides of the tube pan, but not the bottom, so when you slice along the edges, it should come right out. This recipe won’t rise as much as a traditional angel food cake, but thanks to the egg whites, the flavors and texture do come close. If it didn’t rise much at all, something else might have gone wrong.
What happens with only almond flour? Cake too dense? Is it really fin a be bas using almond flour only? Thx
Wholesome Yum M0
Hi Deborah, Yes, only using almond flour will make the cake far too dense.
I followed recipie and when I took it out of the oven and turned it upside down it fell out of the pan, what a mess, and I had pan with feet
Probably parchment paper would not let it grip the bottom
Taste good but will not make again
Wholesome Yum M0
Hi Fred, I am sorry this cake didn’t turn out as expected. Yes, the parchment paper is meant to keep the bottom of the cake from sticking to the pan. It makes it easier to remove. The sides should have held the cake in place while it cooled upsides down. Did you happen to use a non-stick pan or grease the sides?
Hey did a recipe with almond flour only and it rose perfectly and it is fluffy. Maybe cos i used a defatted almond flour?
Wholesome Yum M0
Hi Deborah, Yes that is likely why the recipe worked for you. Defatted almond flour has different properties than traditional almond flour. I did test this recipe with only almond, and it was definitely lighter and had a better texture with the blend as written above.
I do not like coconut can you taste the coconut flour? Can I swap xantham gum for psyllium husk? Will the cake rise high as with almond flour rising is usually an issue? Can I replace vanilla extract with vanilla powder or beans? Thx
Wholesome Yum M0
Hi Deborah, The coconut flavor will largely depend on the brand of coconut flour you use. Some brands are more neutral in flavor than others. I prefer to use Wholesome Yum brand Coconut Flour. I have not tested this recipe with psyllium husk, but it will likely work to maintain the structure of the cake. Yes, feel free to use a scraped vanilla bean in place of the extract. Enjoy!
So with the wholesomeyum coconut flour can you taste the coconut? If i reduce thé egg whites amount can i use only almond flour since i guess coconut flour is used here to absorb some liquid since almond flour is not very absorbent.
Have you tried this recipe with almond extract instead of vanilla or a combo of both?
Can i replace coconut with tapioca or arrowroot for a more neutral taste then ie no coconut taste?thx
Wholesome Yum M0
Hi Deborah, The coconut flavor is very mild in my opinion. I don’t recommend reducing the egg whites. That is the main structure of the cake, so reducing them will change the ratios. Angel food cake needs very specific ratios to be met in order to work. Any extract flavor will work, so long as you are keeping the total amount to 2 tsp. I do not know if using any other alternative flour will work. Again, this recipe is about ratios, and coconut flour provides certain characteristics that tapioca and arrowroot don’t have.
Can I bake the cake in a regular rectangle baking dish?
Wholesome Yum M0
Hi Sara, I have not tested this, but I think it should still work fine. The bake time will be similar to the written recipe, but be sure to keep an eye on it so it doesn’t get too dark.
I LOVED this angle food cake! I have food allergies and have been craving angle food cake since berries are in season. This cut my craving- it was perfect – now I have a new problem…..how not to eat the whole cake myself 🙂 Thank you so much! I HIGHLY RECOMMEND this recipe!! THANK YOU so much for creating it!
What can I use as a sweetener alternative
Is powered swerve ok?
Wholesome Yum M0
Hi Paula, Yes, that should work fine, but your cake won’t be as soft and delicate. For best results, I recommend using Besti powdered Monk Fruit Allulose Blend sweetener.
Angel Food has always been my absolute favorite cake, but since discovering I can’t eat wheat, I thought I would never get to have it again. Until now! I love that this is a gluten-free recipe and am for sure going to try it. Thank you!
I love this recipe..it’s so easy and delicious..thank you.
This has my name all over it! And thanks for the tip on how to cut parchment to line a tube pan.
I love angel food cake. I need to try your recipe, yum!
I had no idea a keto angel food cake could taste so good!
