This decadent keto chocolate bundt cake recipe looks stunning enough to serve at a special occasion — yet it’s easy enough to make anytime you need a chocolate fix! Even with a decadent chocolate ganache icing, this sugar-free bundt cake comes together with a simple collection of keto kitchen staples.

If you like pound cakes but want a version that isn’t chocolate, try my lemon keto bundt cake or vanilla low carb pound cake instead. On the other hand, if you do want a chocolate version of a regular cake, make my keto chocolate cake (or even keto German chocolate cake!).

For a cake that tastes as authentic as the real deal, ingredients make a huge difference… especially flours and sweeteners. I got the best results using Besti Monk Fruit Allulose Blend and Wholesome Yum Almond Flour because the sweetener bakes just like sugar and is particularly excellent at locking in moisture (read: you get an ultra moist cake!), and the flour is ground finely enough for a fine crumb, with no gritty texture. Truly the best for a chocolate cake!

What Is Chocolate Bundt Cake?

Chocolate bundt cake uses typical baking ingredients like any other cake, except bakes away in a special bundt pan. The result is a dense, rich cake that looks stunning with a glaze on top!

Not all bundt cakes align with a keto diet, but this sugar-free bundt cake keeps the carbs low with easy swaps for flour and white sugar.

Ingredients You’ll Need

This section explains how to choose the best ingredients for sugar free chocolate bundt cake, what each one does in the recipe, and substitution options. For measurements, see the recipe card below.

For the cake:

Besti Monk Fruit Allulose Blend – It tastes just like sugar, but most importantly, it keeps the bundt soft and moist! You could also use a monk fruit erythritol blend, but it may have more of an aftertaste and will be more dry.
Wholesome Yum Almond Flour – A fine grind gives this cake an authentic texture and moist crumb. Don’t substitute coconut flour, as the results will be far too dry.
Cocoa Powder – For the best chocolate flavor, use a high quality brand.
Baking Powder – Helps the cake rise. Make sure it’s fresh for best results, because almond flour does not rise as well as wheat flour. Don’t confuse baking powder with baking soda, or your cake will have a terrible aftertaste and won’t rise properly.
Butter – I prefer grass-fed butter for its flavor and benefits, but use your favorite unsalted variety. For a dairy-free option, use coconut oil instead.
Eggs – Use large, whole eggs.
Unsweetened Almond Milk – Get store-bought, or make homemade almond milk. Just avoid added sugar! Alternatively, other types of Vanilla Extract – Adds more depth to the recipe.

For the glaze:

Sugar-Free Chocolate Chips – Dark chocolate chips have the richest flavor for this cake, but milk chocolate ones will work too.
Heavy Cream – Or full-fat coconut milk for a dairy-free option.

Alternate topping ideas:

If you don’t want to serve chocolate on chocolate, try keto strawberry jam, sugar-free caramel sauce, or even a scoop of keto cream cheese frosting! Just keep in mind that these may be run a little more or less than the traditional glaze.

How To Make Chocolate Bundt Cake (The Sugar-Free Way!)

This section shows how to make easy chocolate bundt cake (and chocolate glaze for bundt cake!), with step-by-step photos and details about the technique, to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.

Mix dry ingredients. Add sweetener, cocoa powder, almond flour, and baking powder to a mixing bowl and stir until combined.
Mix wet ingredients. In a large bowl, use a hand mixer to beat the butter, until fluffy. Beat in the eggs, almond milk, sour cream, and vanilla, until the mixture is smooth.
Combine. Slowly beat the dry ingredients into the wet ingredients. Pour the btter into a well greased bundt pan (this one is the perfect size!).
Bake. The cake is ready when a toothpick inserted comes out mostly clean. Allow to cool in the pan for 30 minutes, then invert onto a cooling rack.

Glaze. While the cake cools completely, whisk chocolate chips and heavy cream together in a double boiler until melted. Drizzle cooled cake with glaze and allow to set before serving.

Tips For The Best Keto Chocolate Bundt Cake

Bundt cakes are notoriously finicky, but these tips will help yours bake up clean and easy:

Grease the pan thoroughly. It’s common for bundts to stick to their pans, but there’s a simple solution: Grease the pan generously!
Use room temperature ingredients. It’s important for your butter, milk, eggs, and sour cream to be at room temperature, so that they incorporate properly. If they are cold, the butter will solidify when you mix them together.
Be patient. Bundt cakes take longer to bake than most other cakes, so resist the urge to crack open the oven and check its progress too much.
Cool before glazing. If the cake is still warm, most of the glaze will absorb into the cake and the rest will run off.
Don’t sweat it if the cake comes out in pieces. It would still make a delicious keto trifle!
Bake in a loaf pan if you prefer. You can cut the recipe in half to make it in one 1-pound loaf pan, or make the recipe as is in two loaf pans.

Storage Instructions

Store: Store the cake in the refrigerator for up to 1 week. If possible, avoid glazing until just before serving.
Freeze: Wrap the cake tightly (ideally without glaze) and store in a freezer safe container for 2-3 months. Thaw in the fridge before serving.

Excellent recipe. Next time I make, I will sub the almond milk for 3/4 cup of brewed coffee and see how it deepens the flavor.

But overall, this recipe was an absolute hit. Thank you for sharing.

Wow, this recipe is so yummy! I have some small 6 inch silicone bundt pans and 1/2 the recipe filled 2 of them perfectly. I had to make a couple subs based on what I had – cassava flour, oat milk, and only-monkfruit sweetener. It was perfect! Thank you for this recipe. I’ll be making it for my nephew’s graduation party!

This is the best keto chocolate cake recipe I’ve tried, and I’ve tried many. Does it taste the same as a regular chocolate cake made with sugar and flour? No. But it’s the closest I’ve found, moist and delicious. I also want to applaud your monk fruit/allulose sweetener. It’s the best I’ve tried for baking. Thank you so much!

We don’t have a Monk Fruit / Allulose blend here in Perth, Western Australia. Can I use just Monk Fruit or just Stevia? Thanks.

  Hi Debra, I recommend using my Keto Sweetener Guide if you are going to use a different sweetener to make sure you are using the correct amount.

This is a fabulous recipe. My cake turned out perfectly. The second time I made it, I dropped out half a cup of butter and replaced it with avocado – that tastes great too!

OMG, this recipe was sooooo good! Chocolaty, so moist and absolutely delicious. Chocolate Bundt cake used to be my favorite thing to make before I started keto. I had high standards for it being that it was my signature dessert. This cake was on point in every way. I will be making this again. Thank you for this recipe!

I just want to say thank you! I struggle to find recipes for sweet goodies that don’t contain erythritol because I don’t tolerate it very well, and the allulose/monk fruit sweetener that you use is perfect for me. The taste is amazing and I don’t have any digestive issues with it. Plus after reading about all the benefits that you get with allulose compared to all the other sweeteners out there, it’s a win-win for me. Your recipes always come out delicious! Thanks again, and please please please keep recipes like these coming!!

I’d love to try this but don’t have a double-boiler. Is there something else I can use?

  Hi Melissa, You can make a double boiler by placing a heat-safe bowl (glass or stainless steel) over a saucepan with water in it.

Is it possible to make a smaller cake using this recipe? If you’re not using a Bundt pan what would you need to adjust – the cooking time?

  Hi Carolyn, You can make this as a regular cake and yes you would have to adjust the bake time.
