Free Printable: Low Carb & Keto Food List
Get It NowOne of my favorite things ever is showing you how to make desserts low carb. This low carb keto custard recipe was one of the easiest ones to make, because it’s not that different from regular custard. This dish has no flour to begin with, so we just swap in a low carb sweetener. And since keto egg custard is baked in individual ramekins, it has built-in portion control!
Even though the total time for this low carb custard recipe is around 40 minutes, most of it is hands-off time in the oven. The actual active prep process is super quick!
Plus, you only need 5 ingredients. I wouldn’t be surprised if you have everything you need to make this keto vanilla custard at home right now.
Ready to see how to make custard keto? Yay!
How To Make Egg Custard
Keto egg custard looks really elegant, so you’d never guess how easy it is to make. But it is.
While you preheat the oven, beat the eggs to make them frothy, like this:

Next, heat cream, powdered Besti, and sea salt in a small saucepan over medium-low heat. Stir occasionally, until the temperature reaches 180 degrees F. Be careful not to overheat!
After removing from heat, add in the vanilla extract.
Next, start whisking the eggs and slowly pour the cream mixture into the eggs in a thin stream. It’s important to pour slowly and keep whisking constantly as you do this! This is called tempering.
Set out 6 ramekins and divide the mixture among them. Sprinkle with a little bit of nutmeg if you’d like.

Use a baking pan with tall sides and place the ramekins inside. Then, add enough water to reach halfway up to the top of the ramekin dish. The water will reduce sudden temperature changes, so the custard cooks evenly and doesn’t crack or overcook.
Bake for approximately 30-40 minutes, until just barely (but not fully!) set.
Allow the custard to cool and rest until it reaches room temperature before serving.
My Recipe Tips
- It’s best to use a thermometer to test that the custard has reached 180 degrees F, but if you don’t have one, watch for bubbles. Small bubbles will begin forming around the edges when it’s done. Don’t let it boil!
- If you have any lumps in the custard, you can strain it before baking. Use a mesh strainer and place it over a bowl, then pour the contents. Then you can toss any lumps out.
- Keto vanilla custard can taste egg-y if you overheat it. If it comes to a boil, then the eggs will cook and end up tasting like… well, scrambled eggs. No, thanks! Always use a whisk when mixing the ingredients in this keto custard recipe to make sure nothing sticks to the pan. And most importantly, pour very slowly and whisk quickly when tempering, to avoid cooking the eggs.
- Keep an eye on the keto egg custard – it should be jiggly when done. It’s ready when it’s barely starting to set, and a knife inserted in the center comes out clean.

Frequently Asked Questions
- What Does Custard Taste Like? If you’ve never tasted homemade custard before, you’re in for a treat! It has a velvety texture that is deliciously sweet.Baked keto custard tastes very similar to the inside of creme brulee, just without the crunchy top. Also, creme brulee is often made with just the yolks, while this custard includes the whole eggs. Don’t worry if you’re low carb, though – this keto vanilla custard uses a natural sugar-free sweetener, so it tastes sweet without any sugar. And, my family and friends can’t tell the difference when I make this low carb custard recipe.
- Is Custard The Same Thing As Pudding? No, low carb egg custard and pudding are not the same things. Custard is creamy, is made with eggs and baked in a water bath. Pudding doesn’t necessarily require eggs and milk is the main ingredient. Regular versions are often thickened with cornstarch, but I have a low carb pudding recipe coming soon for you!
- Do I Serve Custard Warm Or Cold? You can serve this low carb custard recipe either warm or cold depending on your preference, but I much prefer it cold. Top it with some strawberries and whipped cream if you’d like!

0I don’t have that many ramekins, would it be okay in a foil lined cupcake pan? I think they would be smaller, so I might need to lessen the cooking time.
Wholesome Yum M
0Hi Carolyn, I have not personally tried this, but it should work fine. Standard muffin pans and ramekins are similar in size, so the bake time should still be close to what’s written in the recipe. Enjoy!
Gretchen
0Any suggestions to make it lower in calories? Could you use a lower cal dairy in place of the cream? Thanks!
Wholesome Yum D
0Hi Gretchen, You could use coconut cream to replace the heavy cream.
Lori
0Excellent recipies! Good instructions, good information about substituting, and delicious! Thank you!
Kathy
0Excellent recipe!
Rhonda
0This is so delicious! I made this yesterday. Now I’m making it again right now because my husband didn’t hear the word portion lol
Robin
0Thanks so much for this recipe! I made it yesterday and it’s heavenly.
Ms E.
0I doubled the recipe and added two tsp of organic vanilla and two tsp of organic maple extract and it tastes just like caramel!!! The texture is perfection! This is a new family favourite and the ramekins make perfect size portions of satiny goodness!!!
Sarah Burns
0Oh my gosh this was amazing!! The only thing I did different was use granulated sweetener instead of the powdered, and I added some pumpkin pie spice. I could literally eat all of this by myself, thank goodness I can eat something so heavenly while on Keto!! I will be making this many, many times!
Maya
0Hello! Can this be transferred to other containers easily? Won’t it break?
Wholesome Yum M
0Hi Maya, It will break apart when you portion it. If you are looking for perfectly portioned custards, I recommend portioning it in individual ramekins before it sets up in the fridge.
Victoria
0Thank you for sharing this recipe. I just made a batch and it is divinely rich. The nutmeg sprinkles match my terracotta ramekins too.
Cindy
0Can you substitute the heavy cream with coconut full fat cream to make it dairy free?
Wholesome Yum M
0Hi Cindy, Yes! Coconut cream will give this recipe the same creamy texture that dairy does. Enjoy!
Diane
0I’d like to make this wonderful custard for a family. Could you advise what the measurements of each ingredient would be? Thanks!
Wholesome Yum M
0Hi Diane, Full instructions including ingredient amounts are listed in the recipe card about halfway down the page. If you can’t see the recipe card, you may need to turn off your browser’s ‘reader mode’ to be able to view it. I hope this helps.
Ashley V. Passinsky
0I see that you say to preheat the oven but I don’t see what temperature it should be? Is it 180 degrees? The same as cooking the custard on the stove?
Thanks!
Wholesome Yum M
0Hi Ashley, Preheat the oven to 350 degrees F (or 177 degrees C). This information is listed in the instructions (step 1) on the recipe card.
Jim
0I’ve made this a few times now. It’s super delicious as is but what I have been doing lately is doubling the recipe, using granulated monkfruit, adding a bit more vanilla and 1/8th teaspoon each of nutmeg and cinnamon. Thanks for the recipe.
Gina Villa
0Wonderful. Enjoyed more than my “non-keto” recipe! Friends all LOVED it.
Peter W
0Can I use Stevia instead of Monkfruit?
Wholesome Yum M
0Hi Peter, I think that would work fine, although, I am not sure how much you would need.
Kim W
0I’m looking forward to making this recipe but I have one very important question: Do I use boiling water to pour around the ramekins like I would for regular baked custard or should it be cold or room temperature? I can’t hardly wait!!
Wholesome Yum M
0Hi Kim, Yes, hot water should be added to the pan.
Karen
0Delicious!!! It is so dreamy! OMG- I have missed egg custard!!!!!!
Anne Worlledge
0Can I use the granulated erythritol in recipes? I bought the granulated one as I didn’t realize some recipes say powdered
Wholesome Yum A
0Anne, you wouldn’t be able to do that in this recipe as the results would have a grainy texture. If you have a spice grinder or food processor, you can add the sweetener you have and pulse it down until it becomes powdery.
Ashlee
0This was absolutely amazing! My fiance and I both loved it.
Gail Sprlyan
0Patricia Ryan, you can get erythritol from a health store in most shopping complexes in Australia. thats where i get mine and then put into mixer and just keep mixing until it becomes almost powder. you wont get it looking like icing sugar though but pretty close. everything else you will find in woolies or coles. heavy cream is thickened cream in Aust.
Fay
0I don’t have ramekins, would silicone muffin cups work?
Wholesome Yum A
0Hi Fay, that might work but you’ll definitely have to decrease the baking time. Let me know if you try it!
