The best keto chocolate cake 

When it comes to keto desserts, it’s safe to say we are huge fans. 

While desserts should be enjoyed in moderation, we have a few that we make very regularly. In a single week, we often make chocolate chip cookies, cupcakes, and especially ice cream. It also wouldn’t be uncommon for us to prep some candy, too.

Oh, and let’s not forget the family favorites that are requested almost daily: keto cheesecake and keto peanut butter cookies!

Whenever we have a celebratory event or just want something classic and delicious, we whip up a keto chocolate cake. 

Can keto eat cake? 

When made using low carb ingredients, cake CAN be part of a keto diet. Swap out the sugar for sugar substitutes and use low carb flours, you can create a cake that looks and tastes just like any cake out there.

Why this keto chocolate cake recipe will be a low carb staple-

  • It needs less than 8 ingredients. Okay, so that doesn’t include the frosting, but this cake tastes that good, you don’t even need it (but you should!). 
  • Ready in 30 minutes. You’d think a layer cake would take a long time to cook, but really, 30 minutes is the MAXIMUM time it could take. 
  • There is barely any prep required. You mix the wet ingredients, then add the dry ingredients and that is it. Seriously, even a toddler could do this. 
  • You can make them as cupcakes! Ever worry about portion control? Want to cook this cake in half the time? Bake them as cupcakes! 

Can we just lament on how good this chocolate cake tastes and what an incredible texture it has? It’s moist, fluffy, and has a gorgeous, tender crumb. The chocolate flavor is evident throughout and seriously, I dare you to stop yourself after one slice! 

Ingredients needed

For such a fabulous looking dessert, you’ll love the simple and easy ingredient list needed. If you’ve made any of my low carb dessert recipes before, you’ll have all these ingredients on hand. Here is what you’ll need: 

  • Almond flour. Blanched almond flour must be used, as it keeps the cake fluffier in the center. Do not use almond meal, as that makes the cake heavy and dense. 
  • Cocoa powder. Use a good quality cocoa powder and sift it first if there are clumps in it. For a richer flavored cake, use dark cocoa powder. 
  • Allulose. My preferred keto granulated sweetener because it dissolves exactly like sugar does. Erythritol and monk fruit sweetener should work too. 
  • Baking powder. Gives the cake some rise and leavens it out. 
  • Salt. Enhances the sweetness of the cake. 
  • Eggs. Your eggs must be room temperature, to ensure it doesn’t cool the butter down when beating it together. 
  • Butter. You want the butter to be unsalted, and at room temperature, not melted! 
  • Vanilla extract. A must for any good cake recipe! 
  • Frosting. What is a chocolate cake without some keto frosting

How to make a keto chocolate cake

Simple is an understatement for this recipe. Honestly, it has to be one of the easiest cakes you’ll ever make, keto or not keto. While the frosting is optional, I highly recommend it because it looks so darn good and who doesn’t love extra chocolate?

Let’s jump right into it! 

Step 1- Cream the wet ingredients

Start by creaming together the eggs, butter, and vanilla extract until smooth. I usually just mix by hand but you can use a hand mixer if you prefer.

Step 2- Make the cake batter

Next, add the dry ingredients into the bowl and mix until a thick cake batter remains. Try not to over-mix the batter, because sometimes that can yield an overly gummy cake.

Step 3- Bake the cake

Now, grease two 9-inch cake pans and set aside. Evenly distribute the cake batter between the two cake pans and use a spatula to smooth out the top.

Bake the cakes for 27-30 minutes, or until a skewer comes out clean. I usually check around the 27-minute mark and keep checking every minute until it is done. 

Step 4- Frost the cake

Finally, let the cakes cool completely. Once cool, generously spread keto frosting between the two cakes and around the exterior. Let the cake sit for at least 30 minutes before slicing and serving.

Tips to make the best recipe

  • Do not over-bake the cake, as the cake continues to cook as it is cooling down. It shouldn’t take longer than 30 minutes, so check at the 27 minute mark.
  • If your almond flour and cocoa powder have clumps, be sure to sift them both carefully. 
  • If you only have salted butter, you can use that and omit the salt from the cake batter.

Storage instructions

  • To store: Leftover cake can be stored in the refrigerator, covered. It will keep well for up to 2 weeks. 
  • To freeze: You can freeze keto cake by placing it in a freezer friendly container. It will store well for up to 6 months.

  1. hey arman! i’m a teen who lovesss baking and ive been trying to bake healthier food, i was wondering if you could make a recipe for quest bars? i absolutely love those but the ingredients aren’t the cleanest. may i also ask for them to be made of oat flour? thank you!

    1. 5 stars
      This recipe is a family favorite. We prefer to double or triple the vanilla. Many of Arman’s low-carb recipes have become staples.

  2. 5 stars
    Really good!!! Used Swerve sweetener instead of liquid stevia! Superrrr sweet, May tone back the sweetness next time, but it is delicious! Definitely made the icing!

  3. I’m making this wonderful cake for a birthday party for 20 people! What do I need to change to make it a sheet cake?

    1. You’ll need to double or triple the amount and change the bake time. I haven’t tried it as a sheet cake so play around with the times. Check at the 30 minute mark, then in 5 minute increments.

  4. I can not use almond flour, rice flour or coconut flour due to allergies which i recently got tested for.
    Can i use Oat flour for any of your recipes? If so do i need to use any ingredients along with oat flour to get same consistentcy

  5. Hi and thank you! I am guessing I can cut the recipe’s ingredients in half to make one cake pan, yes? It is just me in my house who eats low carb.

  6. 5 stars
    Keto chocolate cake looks amazing. My husband said that I need to make this and I agree. Thanks for all your recipes.

  7. Hello!
    I am making this cake now and I was wondering, what do you grease the pans with? Is coconut oil OK? Do you have to put almond flour also?
