Ingredients in This Keto Bundt Cake Recipe
This is all you need to make this delicious keto chocolate bundt cake.
For the Healthy Chocolate Cake Batter
- Almond flour – Blanched or super-fine almond flour, not coarse almond meal
- Granulated sweetener of choice – Use a natural, zero-calorie sugar substitute such as monk fruit.
- Unsweetened cocoa powder or cacao powder and Dutched cocoa powder – I use a blend of half organic cocoa powder and half Dutched cocoa powder for my cake. The Dutched cocoa adds a deeper, darker color to the cake. You can, of course, simply make the cake with unsweetened cocoa powder.
- Baking powder – Adds some volume.
- Unsalted butter or margarine – The cake tastes great with either. For less saturated fat, use margarine.
- Avocado – If you haven’t tried baking with avocado before, I can’t recommend it enough. Avocado makes this almond flour chocolate bundt cake incredibly moist, rich, and velvety. It also packs the keto cake with healthy fats and antioxidants.
- Eggs – There are quite a few eggs in the recipe. That’s because they help bind naturally gluten free almond flour.
- Vanilla extract – Adds flavor.
- Chocolate extract (optional) – Enhances the chocolate flavor of an already perfect chocolate cake.
- Espresso powder or finely ground coffee (optional) – For a very chocolaty cake, add some espresso powder. You can’t at all taste it, since it mainly augments the chocolate flavor.
- Salt (optional) – Enhances flavor.
- Nut milk of choice – Unsweetened almond milk is a healthy option.
For the Sugar-Free Chocolate Ganache
- Sugar free dark chocolate bar or chocolate chips
- Heavy cream
- White granulated sweetener of choice (optional) – to adjust the sweetness, if necessary.
Optional Low-Carb Toppings for This Sugar Free Chocolate Bundt Cake Recipe
- Add a pop of color and top with low-carb berries such as keto-friendly raspberries or strawberries.
- Whipped cream
- Sugar-free ice cream
How to Make Chocolate Keto Bundt Cake
- Preheat oven to 350℉ (180℃).
- Grease bundt pan, lightly sprinkle with cocoa powder, and set aside.
- Puree avocado: Puree avocado with an immersion blender, food processor, or electric mixer on high. Puree until no lumps remain and it’s silky smooth.
- Whisk together the dry ingredients in a medium bowl.
- Beat the wet ingredients in a large bowl. Combine the avocado puree and butter. Then, beat in the eggs one at a time. After that, mix in the remaining wet ingredients.
- Slowly add the dry ingredients to the wet ingredients and mix well.
- If you made the cake with half cocoa powder and half Dutched cocoa powder, taste the batter: You may want to add another tablespoon of monk fruit sweetener.
- Transfer the cake batter to the prepared bundt pan. Next, tap the bottom of the pan a few times on your work surface to remove any air bubbles.
- Bake the cake: The baking time is 50-55 minutes at 350℉ (180℃) or until a skewer or knife comes out clean. If the skewer or knife doesn’t come out clean, bake it some more and check it every 5 minutes. It’s okay if there are a few crumbs on the knife (you just don’t want globs of batter clinging to it).
- Remove from oven and let your keto bundt cake cool for 10 minutes in pan: Then flip it onto a cooling rack and let it fully cool.
How to Make the Sugar Free Chocolate Glaze
Here’s how to make the keto chocolate ganache.
- In a small saucepan, gently heat 1/4 cup heavy whipping cream.
- Add a sugar free chocolate bar or chocolate chips: Break up a 4-ounce sugar free dark chocolate bar, gradually adding it to the heavy cream. Blend with a spoon. Taste to check sweetness. Add a teaspoon at a time of sweetener if you want it sweeter and gently heat the icing again to dissolve any added sweetener.
Heat on low until desired thickness is reached. - Drizzle over the cooled cake and give the glaze time to firm up.

Raspberries and strawberries are fine in moderation on a keto diet and are lower in carbs than other fruits.
I don’t recommend stevia, since it has a slightly bitter flavor.

Notes







This cake turned out perfectly. Thanks so much for this fantastic recipe. My guests loved it!
Thanks for the review. Glad your guests loved it.
It was hard to not eat it all at once! Thanks for the terrific recipe!
Thank you for the review. Glad you enjoyed the cake.
This cake was so decadent! Intense rich dark chocolate flavor. There is no way anyone could tell this was made without “real sugar” or gluten! I love Cathy’s recipes in that they are healthier and still absolutely every bit as delicious as a “normal” cake. In fact these goodies are my new normal!
Thanks so much for your post. I’m glad you love the cake too!
Cathy’s cakes are a work of art. They are a visual treat and taste really good too! It’s hard to believe she doesn’t use any sugar or butter they are so rich. She baked a dark chocolate cake for my fiancé’s birthday and we especially liked it because it wasn’t so sweet that it overpowered the raspberries which added a nice contrast of color, texture, and tastes.
Thanks for your nice comment, Art. I am glad you liked it and look forward to baking another one for you sometime.
Wow! What a delicious chocolate cake! Normally, “healthy” cakes can be bland and/or dry, but Cathy’s is neither. This one is full of true chocolate yumminess and very moist!
This cake is a game changer! I want it in my life on a regular basis. Rich. Luscious. Chocolate high. But no carb crash. No guilt. I am a convert to avocado and monk fruit.
This chocolate cake is a winner! A healthy treat and tastes better than anything else. What’s not to love?
Beyond Fabulous & Delicious! Excited to have a Beautiful, Creative Dessert Option. Had one shipped even, completely flawless with Cathy!
My husband and I decided to bake the chocolate bundt cake. Gathered the ingredients, some of which were less familiar with. Cathy’s instructions are thorough and thoughtful, so we were confident it would turn out well. What a surprise! Low carb/sugarfree with such rich dark chocolate flavors.
Lemon poppy cake is next!
I’m so glad I made this cake. It was a big hit at my friend’s birthday party. We loved that’s it’s made of almond flour and avocado and sooo chocolatey. Healthy delish!
Thanks for letting me know. Glad you enjoyed the cake!
I’m not sure if I perhaps did something wrong. The batter was very thick. Is this normal?
If not, how can I trouble shoot this?
If you followed the recipe, the cake should be perfect. It’s not a super thin batter. The wet ingredients are butter, avocado puree, 6 large eggs, and almond milk. Depending on the situation, you could add another egg or a little more almond milk. Let me know how it turns out.
Even though the batter was very thick, the cake turned out great! It was a hit with the family! I think I may add an extra splash of almond milk next time. Thank you for this awesome recipe.
You’re welcome! I’m glad you enjoyed it!
This cake is amazing and I love that it’s sugar free but I was wondering about the cholesterol. Does it take away from this cake being healthy? I have high cholesterol and was just wondering. Thank you!
The use of avocado reduces the amount of cholesterol typically found in a cake like this. Whether the cake is appropriate for your diet is something you need to decide based on the nutrition facts that are published in the Recipe Card.
Good point! Thanks again for the delicious recipe!
