Keto Chocolate Cake with Creamy Sugar-Free Frosting

Hello, hello!

This ketogenic chocolate cake proves that healthy baking doesn’t have to be complicated or costly. I used mostly common baking ingredients to create an extremely low-carb chocolate cake that turns out moist and deeply chocolatey.

Taste and Occasion

The ketogenic diet—essentially a very low-carb approach—has been popular for some time. Even if you don’t follow it, you’ll likely enjoy this keto chocolate cake: it’s sugar-free, gluten-free and can be dairy-free if you skip the frosting.

It comes together quickly. My goal was to develop a cake that feels familiar, close to a “regular” cake, rather than many keto bakes that rely heavily on fats like butter, coconut oil or peanut butter. This cake is different: it aims for a balanced texture and classic chocolate flavor without unusual or hard-to-find ingredients.

The recipe is straightforward and produces a tender sponge-like crumb when handled gently. Keep an eye on mixing and baking time so the cake stays moist rather than drying out.

For the photos I coated the cake with a simple frosting; the pictures were taken with my Sony α7R II.

Ingredients

Like the low-carb apple cake and the almond lemon cake I based this one mainly on ground almonds and replaced granulated sugar with xylitol or erythritol—both are widely available in supermarkets and online.

The rest of the cake uses eggs, almond milk and cocoa. You don’t need coconut flour, potato fiber, guar gum or other specialty flours—just everyday pantry items.

This cake is essentially a sponge made low-carb: the important points are not to overmix the batter and to watch the baking time so the cake stays tender.

For a finishing touch you can add a frosting, but the cake is delicious on its own.

How to make the Keto Chocolate Cake

Preparation is simple. Preheat the oven to 350° F / 175°C. Grease a small springform pan (8 inches / 20 cm) and lightly sprinkle with sliced or chopped almonds.

Separate the eggs. Beat the egg yolks with the sweetener until the mixture is very frothy. In a separate bowl, whisk the egg whites until stiff peaks form.

Stir liquid coconut oil (or melted butter) and almond milk into the foamy yolk mixture. Combine the ground almonds with baking powder, a pinch of salt and the cocoa powder, then gently fold this dry mix into the wet ingredients. Finally, fold in the beaten egg whites carefully so you keep as much air as possible.

Pour the batter into the prepared pan and smooth the top. Bake for about 30 minutes, or until a toothpick inserted near the center comes out mostly clean but the cake is still moist.

Optional frosting: Beat softened butter with powdered erythritol until fluffy. Add cream cheese and cocoa powder and mix until smooth. If the frosting is too thick, add 1–2 tablespoons of almond milk to reach spreading consistency. Spread on the cooled cake.

Top Tip

The cake freezes well, even with the frosting applied. Nutrally: when divided into 8 pieces, each unfrosted slice contains roughly 9 g of carbohydrates.
