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

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.

Made this chocolate cake for my diabetic grandson’s birthday to allow him to have cake, but yet be mindful of the carbs. I had to bake it for 17 minutes, but it turned out great. The cake consistency is a little firmer than regular cake, the the creaminess of the frosting balanced it out beautifully – will be making this one again!
My son is allergic to tree nuts so I avoid almond flour, etc. Can I substitute regular flour? Or any other suggestions? Thank you this looks absolutely amazing and I can’t wait to try!!
Has anyone tried this recipe with “Just Egg” as the egg replacer?
Hi,
Can I make this with flax eggs? Thank you for your time!
Sorry we have not tried!
Hello. I am only making a single layer of the cake. Will the cream cheese frosting be the right amount or should I make half? Thank you. Can’t wait to serve it for my daughter-in-law for her birthday. She is Keto.
You could definitely do half!
Thank you!
Made this for a friend’s birthday and added 1tsp cinnamon and 1/2 tsp cayenne to the cake only. Used the keto icing recipe and it was mind blowing!!! I’ll be making this every week!!
Katie,
Thank you so much for this recipe. My wife is a Type 1 Diabetic and this is the ONLY cake that she request I make each time for her birthday. We really enjoy it…yes, “we” because even I eat it! As a testament to how good it is, my nephew who does NOT like chocolate cake, said that this is the one chocolate cake that he will eat and enjoy. I have frosted it with different frostings: chocolate whipped-cream cream cheese frosting, chocolate peanut butter whipped cream frosting, Raspberry whipped-cream cream cheese frosting, etc. Thank you so much again.
Your frosting ideas sound fantastic!
I made this tonight, but I used maple extract (per the kiddo’s request), almond milk, and a half-cup of Allulose. After reading the comments, I baked it for the 15 minutes at 350 the recipe calls for, but I used the Convection setting on a countertop oven. It came out perfect!
I frosted it with a cream-cheese stabilized whipped cream (Heavy cream, allulose, Neufchatel cheese, with added cocoa powder and maple extract). My 11 year old is a happy camper, and so am I!
A friend of mine has a nut allergy, so I may try to adapt this recipe in the future to see how it works with coconut flour.
Made this just now. Guess I didn’t grind my chia seeds well enough because it was “gritty.” It also didn’t rise. ?? Baking soda is good. Put it in until toothpick came out clean-probably 18 min. Has anyone else used all chia or all flax for their egg substitute? Tastes okay to me but my son won’t eat it because it’s “weird.”
The cake turned out perfectly. The texture and flavor were scrumptious. I used the suggested chocolate cream cheese frosting as well and made a low sugar raspberry jam for the center.
My only issue is that my husband and I must be sensitive to erythritol, we got sick If I make this again, I’ll just use real sugar.
Has anyone had success making this recipe with Sucralose?
This chocolate cake and the frosting recipe paired with it were amazing! I used all Dutch cocoa powder since that was all I had. I also used monk fruit sweeteners for both recipes. This does not taste like a keto dessert. Your recipes have all been great. Thank you so much for sharing them!
This looks so delish! I have a question, my husband and I are just getting into ketosis and would love to make this to have some alternatives but don’t want to chance heavier meals or snacks and being knocked out of ketosis. Will eating this kick you out of ketosis? I know it’s low carb but still wondering. Also, we are trying to eat dairy free (not including eggs) eliminating milk and cheese products. Is there dairy free icing option or just go icing free? Thank you!!
Hi, you can definitely you your favorite nondairy milk. We are not on a keto diet, ourselves, so we do not know about the specifics of staying in ketosis.
Are there eggs in the cake or not? The recipe lists them but the video doesn’t show them being added.
Simple & quick recipe
Amazing results!
I bought a piece of keto chocolate cake in my hood it was dry.
This recipe doesn’t need too many ingredients & it’s chocolatey & moist!
Thank you for sharing this recipe!
Hi, Has anyone used the Volupta Erythritol & Monk Fruit extract sweetener? How much would I use for this recipe? Thx!
Amazing recipe I’m diabetic and it’s perfect so moist. I froze the cake and when defrosted it was even better love it
