Low Carb Flourless Chocolate Cake Recipe with Fudgy Chocolate Frosting on Metal Background

A question we get asked a lot is how to stay keto during celebrations, such as holidays and birthdays. Cake is an integral part of birthdays (as well as other celebrations) for most of us, and there’s no reason you can’t have cake on keto! Of course, the kind of cake matters; we took the guesswork out of it and came up with the best version of chocolate cake we could. This would make the perfect keto birthday cake!

Our flourless chocolate cake is dense, rich, and intensely chocolatey. We make it in the Instant Pot because it’s quick and easy (and bonus, if it’s hot outside it won’t heat up the kitchen!); however, we also give easy instructions on how to bake this cake in an oven.

How to Make a Simple Chocolate Cake

Baking is much more of a science than cooking is because it requires specific amounts of dry ingredients, wet ingredients, and leavening agents to rise properly and have the right texture. And of course it should taste good (otherwise there’s just no point!).

In its most basic form, chocolate cake is flour, sugar, chocolate (either in the form of cocoa powder or melted chocolate), fat (usually oil or butter), leavener, and sometimes eggs. Other flavor enhancers, such as vanilla, espresso powder, sea salt, etc. can be added to enhance the flavor of chocolate, making it more intense by pulling out various flavor nuances.

These basic ingredients are combined in specific ratios and baked (typically in a 350F oven) until a wooden pick inserted in the center comes out clean.

Low Carb Cake

Low carb baking is different from regular baking because we typically avoid gluten and sugar. In order to achieve a cake-like texture that’s neither too light nor too dense, it’s helpful to use a blend of various alternative flours, such as almond flour, coconut flour, etc.

The other main component that should be chosen carefully is the sweetener in low carb baking. Instead of using regular sugar, we have several alternatives available, such as xylitol, erythritol, stevia, etc. The point is to get the right sweetness level without a cooling effect (that erythritol can sometimes have) and without any bitterness (which stevia can sometimes cause). This is why we frequently use a combination of erythritol and stevia (to avoid both the cooling effect and bitterness).

Flourless Chocolate Cake

Oftentimes a flourless chocolate cake refers to a chocolate torte, which is basically a dense cake made by baking chocolate custard. It’s egg-based and is naturally gluten free, and is commonly topped with fresh berries, a sprinkling of powdered sugar, or chocolate ganache.

    What can I substitute for Stevia Glycerite and how much?

    Reply
    • Lara says

      You can use regular liquid stevia extract instead and you probably will need to use 1/3 more.
