Why make a Keto Chocolate Cake?

It is amazing how you can eat certain sweets and still be able to maintain your healthy weight and well being.

This keto cake is perfect for both a sweet snack or celebration.

It is super simple to make with a few ingredients.

This will be my birthday cake next year.

Most of the people I know, who follow the Keto diet would prefer quick and easy sweet treats, ready in under 30 minutes. It is understandable, since meal prep takes some time and we usually don’t want to spend time baking.

This Keto chocolate layer cake is more of a spacial occasion or a weekend treat that requires 1 hour to make.

What tools you’ll need to make a Keto chocolate cake?

I split the cake batter into two equal parts and baked it in two 6-inch round pans. So you need two 6-inch round cake pans for baking.

Then once cooled, I cut the cake layers into two thinner layers horizontally. I used a large serrated knife.

Actually gluten-free cakes are very easy to cut in half, because they are moist, but not too crumby.

For the chocolate mascarpone filling, I used an electric mixer to mix in the heavy whipping cream.

Then you’ll need a spatula to smooth out the filling between the layers of chocolate cake.

How to make this Keto Chocolate Cake:

  • You first bake the cake layers.
  • Let them cool and then cut in half each layer horizontally.

Can you make a Keto chocolate layer cake with two layers only?

Yes, but I like cakes with thinner layers and a lot of filling in between.

  • Prepare the filling.
  • Spread filling between the layers. Add ganache on top.
  • Garnish with berries.
  • Serve or store in the fridge for up to 1 week.

How long to bake the cake layers for?

When it comes to baking cakes, under baked cake, that collapses is my biggest nightmare. If you leave this cake slightly under baked, it won’t be a big deal, because you’ll achieve a more tender crumb.

If you bake the cake for the time that I suggest, it will most likely bake perfectly, but  it will be slightly more dense.

I baked the cake layers in two 6-inch pans for 27-30 minutes, until the tops were set and toothpick inserted cake out clean.

What sweetener to use in this Keto Chocolate Cake?

I recently tried Pyure organic Stevia Sweetener. I liked it. I think it may be slightly sweeter than Swerve.

In this Low-carb chocolate layer cake I used Swerve Confectioners for both the layers and whipped cream filling.

Erythritol can be substituted in equal amounts.

How to garnish Keto cake?

I left this cake “naked”. It is a technique, where you layer the cake layers with filling in between, but don’t add any frosting on top or around the sides. It is a great and effortless technique for non cake makers.

I made a very minimal ganache with sugar-free dark chocolate and heavy cream and added it on top of the cake.

I then decorated it with fresh strawberries, blueberries and raspberries.

Don’t want to make a whole cake, but prefer a Keto mug cake instead?

You can use most of the ingredients to make a mug cake. You can bake it in the microwave or in the oven. It is so good!

Mug cakes are a staple in Keto diet, especially to chocolate lovers like me.
