Easy Keto Chocolate Cake, Tender and Fluffy

A wonderfully tender and fluffy keto chocolate cake with chocolate frosting. Without the frosting, it’s wholesome enough to be served for breakfast!

Keto Chocolate Cake

When I was a kid, my favorite cake was the simplest chocolate sheet cake with chocolate frosting. Preferably with rainbow sprinkles on top. This keto chocolate cake reminds me of that favorite childhood cake.

It’s a very easy recipe. And if you don’t use any frosting, it’s especially easy – and quite appropriate as a snack cake or a breakfast cake. I actually prefer it without the frosting, but since I made it for the blog today, I included the frosting.

Nutrition info for the no-frosting cake is provided below in the recipe card’s notes.

The ingredients used in this recipe

These are the ingredients you’ll need to make this tasty cake:

  1. Eggs
  2. Unsalted butter
  3. Sweetener (I use stevia glycerite)
  4. Vanilla extract
  5. Almond flour
  6. Cocoa powder
  7. Kosher salt
  8. Baking soda
  9. For the Chocolate Frosting: unsalted butter, heavy cream, cocoa powder, vanilla and stevia

How to make keto chocolate cake

It’s truly a very easy recipe. The detailed instructions are in the recipe card below. Here are the basic steps:

  1. Start by whisking together the eggs, melted butter, stevia and vanilla. I use a hand whisk.
  2. To the same bowl, gradually add almond flour and cocoa powder and whisk them in.
  3. Mix in the salt and baking soda.
  4. Transfer the batter to a well-buttered 8-inch glass baking dish. Bake about 18 minutes at 325 degrees F.
  5. Cool completely, then frost.

Can I use coconut flour instead of almond flour?

Unfortunately, you can’t. Coconut flour is extremely absorbent and you would need to adjust this recipe quite a bit in order to use it instead of almond flour.

I do have a wonderful recipe for keto chocolate cupcakes that are made with coconut flour.

Can I use almond meal?

It’s best to use blanched, finely ground almond flour in this recipe if you’d like to ensure that the keto chocolate cake comes out fluffy and tender.

I don’t like stevia. Can I use a different sweetener?

You can probably replace the stevia with a granulated sweetener. The amount that I use equals 1/2 cup sweetener. I haven’t tried it, though. And if you do use a granulated sweetener, check the batter – if it’s too thick, you might want to add 1-2 tablespoons of milk or water.

It’s best to use natural cocoa powder

This cake relies on baking soda as a leavening agent, and the baking soda requires acid in order to activate. So make sure you use natural cocoa powder and not cocoa powder that was treated with an alkalizing agent.

Is this keto chocolate cake healthy?

It’s not broccoli. 🙂 But I do believe that a cake made with almond flour and stevia is a better choice than refined carb cakes made with sugar and wheat flour. Take a look at the nutrition profile for a slice of this cake. I think it’s pretty impressive:

How to keep leftovers?

You can slice the cake, then store the slices in an airtight container in the fridge for up to 5 days. You can also freeze unfrosted cake slices.

Another good recipe is this recipe for keto carrot cake. It’s easy, tasty, and relatively healthy (as far as cakes go).

  • Preheat oven to 325 degrees F. Grease an 8-inch square glass baking dish with butter. Be generous when greasing to ensure the cake releases easily from the pan.

  • In a large mixing bowl, whisk together the eggs, melted butter, stevia, and vanilla extract.

  • Gradually whisk in the almond flour and cocoa powder.

  • Finally, whisk in the kosher salt and the baking soda. The batter will be quite thick.

  • Pour the batter into the prepared baking dish and smooth the top out with a rubber spatula. Bake until the center is set and a toothpick inserted in it comes out clean, 18-20 minutes.

  • Cool the cake, in the pan, completely, about 1 hour, then frost if you wish.

  • To make the frosting, place all the frosting ingredients in a medium bowl and whisk by hand. Or beat with an electric handheld mixer on low speed until smooth and fluffy, 1-2 minutes.
