This rich and decadent chocolate keto cake is shockingly delicious… Every time I serve it, people always ask for the recipe!

Secretly Vegan Low Carb Flourless Chocolate Cake Recipe

The Ultimate Flourless Chocolate Cake

Why should you make this chocolate cake?

Simply put, because it is quite possibly the best chocolate cake you will ever make, even if you aren’t on a keto diet.

The first time I made the recipe was for a friend’s birthday party, where not a single person in attendance aside from the host was on a low carb diet, and yet people went absolutely crazy for this ultra fudgy chocolate cake. In just a single night, I was already asked by three more friends to make cakes for their birthdays too!

Keto Frosting Recipes

For the chocolate cake in the photos, I used this Chocolate Cream Cheese Frosting recipe.

Feel free to use your favorite vanilla or chocolate buttercream frosting, homemade or store-bought.

Or change up the flavor by topping the cake with cream cheese frosting, peanut butter frosting, whipped cream, ice cream, sliced strawberries, or coconut frosting. Just be sure to let the cake cool completely before spreading icing on top.

It’s also really good topped with Coconut Whipped Cream!

Can You Use Regular Sugar?

Yes, if you’re not counting carbs, the cake recipe works just fine with regular granulated sugar as well. I know this because I tested it on myself (the things I have to do for my job…).

Even if you use real sugar, you still only need 2/3 cup total for an entire double layer cake, which is crazy low in comparison to traditional chocolate cake recipes that often have at least double that amount!

For A Vegan Keto Cake

While flourless chocolate cake recipes usually call for eggs, making a vegan version was surprisingly easy. I simply mixed three tbsp Bob’s egg replacer with 150g water (half cup plus two tablespoons), let it sit for a few minutes to thicken, and then used that as my three eggs in the recipe.

If you need six eggs for a double layer cake, just use six tablespoons of the egg replacer mixed with 1 1/4 cup water instead. I haven’t tried making a version using flax egg yet, but be sure to report back if you experiment!

For A Paleo Or Gluten Free Cake

For a paleo cake, sweeten with either the erythritol option listed in the recipe or use 1/2 cup date or coconut sugar instead. The low carb cake recipe is naturally gluten free, no substitutions necessary. It’s made with almond flour, which is simply ground up almond meal. (For a cake that’s made with regular flour, I recommend this Vegan Chocolate Cake.)

Ingredients

  • 1 1/2 cups fine almond flour
  • 1/4 cup cocoa powder
  • 2 tbsp dutch cocoa or additional regular
  • 2 1/4 tsp baking powder
  • 1/2 tsp salt
  • 1/3 cup water or milk of choice
  • 3 eggs (including the vegan option listed earlier in the post)
  • 1/3 cup granulated erythritol or regular sugar
  • 1 1/2 tsp pure vanilla extract

Instructions

  • *For a double layer cake, simply double the recipe and bake in two 8-inch pans. I listed a few keto frosting ideas above in the post. And if you're a visual person, be sure to check out the recipe video above!
    Preheat oven to 350 F. Grease an 8-inch pan, and line with parchment. Stir all ingredients together very well, then spread into the pan. If needed, use a second sheet of parchment to smooth down. Bake 14 minutes on the center rack (some ovens require more baking time, so continue cooking until firm if needed). Let cool completely before frosting.

    I made this for my diabetic husband’s birthday who is now 75% off diabetes meds. He loved it so much!!! I used choco buttercream for the icing and filling. Then made crisscross lines in the center using keto condensed milk. I bet caramel is even better but It was good enough for him! This is definitely a keeper! Thank you for sharing this recipe!

    Just made this and it turned out beautifully 🙌🏼💕

    Changes I made:

    I used almond meal, not superfine.

    I used 1/2 cup of powdered monkfruit sweetener

    I ADDED 1/4 cup of olive oil beca I like my cakes super moist.

    Divine!!!! 10/10 🍫🥮🍰🧁

    You rock Katie!

    All the best!

    This cake is absolutely incredible, and SO easy to make! The crumb is excellent, it has great structure, and it’s perfectly moist (without feeling “wet”, if that makes sense) even straight out of the fridge. My husband, who is a beginner/novice baker, made me this for my birthday, and it was utterly delicious! 🙂 We have a convection oven, so he did need to reduce the temperature by 20 degrees and baked for 20 minutes, which seemed just right.

    Additionally, he used the suggested optional extra cocoa (because I love a really dark, rich, chocolatey flavour), and used water instead of milk. He also added 1/8 teaspoon each of pure stevia and monk fruit sweetener (on my suggestion) as I find it balances out the sweetness very well when using erythritol.

    I cannot believe this is such a simple yet utterly delicious recipe, and it’s become my go-to recipe for a chocolate keto cake and cupcakes. Absolutely amazing! Thank you so much!

    PS. I will write a separate frosting review – but in short, the chocolate cream cheese frosting makes enough to frost a two-layer 8-inch cake!

    I made the single recipe into a dozen small donuts! Topped with some melted chocolate. (Baked at 400’ for about 10-12 minutes) Really quite good. Thank you!

  7. Michelle says

    5 stars
    This cake and the chocolate cream cheese frosting are a-mazing! I’ve made them both too many times to count and everyone loves it. I see that many think it takes longer to cook. I follow the recipe as it is and mine bakes at the time stated if not a little less. It all really depends on your oven. Katie, I love your recipes and this is my family’s all time favorite!

  8. Amber says

    She’s not kidding! It’s the best chocolate cake I’ve made. I could not tell it was sugar and flour free. I made the chocolate cream cheese frosting too! The only thing I changed was using half regular cocoa and half dark cocoa for the frosting. Oh yeah!!!!!!

  9. Susan L. says

    15 minutes will bake this cake all the way through? I’m worried about uncooked eggs…. can anyone answer this question?The cake honestly cooks that fast?

  10. Christine says

    Try this recipe along with the frosting today. I’m going to adapt it a little bit. It’s a little dry and I’m also going to switch over to stevia I think the aftertaste from that is not bad compared to the swerve that I used. But not a bad recipe to make. Thank you for sharing your recipes.

    Came out absolutely delicious! The other people who had it weren’t on keto and loved it! I made it with the chocolate cream cheese icing which was ridiculously good! Highly recommend and will definitely make it again!
