Ingredients
For the Cake
- 2 cups almond flour
- 1 1/3 cups powdered or granular keto sweetener
- 1 cup natural cocoa powder
- 1 tablespoon baking powder
- 1 teaspoon baking soda
- 3/4 teaspoon fine salt
- 6 large eggs
- 1 cup unsalted butter, melted
- 1/4 cup unsweetened non-dairy milk
- 2 teaspoons pure vanilla extract
- Cooking spray
For the Frosting
- 1 cup unsalted butter, softened
- 1 cup powdered keto sweetener, such as Confectioners’ Swerve
- 1/3 cup natural cocoa powder
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon fine salt
- 1/4 cup unsweetened, non-dairy milk, divided
Methods
-
Gather the ingredients.
Position a rack in the center of the oven and heat to 350 F.
-
In a large bowl, whisk together the almond flour, sweetener, cocoa powder, baking powder, baking soda, and salt.
-
Whisk in the eggs, butter, milk, and vanilla extract until smooth. The batter will be very thick.
-
Lightly spray the bottom and sides of a 9 x 13 inch baking pan. Then line the pan with parchment. Pour the batter into the pan, spreading into an even layer.
-
Bake until a toothpick inserted in the center of the cake comes out clean, about 30 minutes. Let cool completely.
Meanwhile, make the frosting before removing from the pan (remove and discard the parchment).
Make the Frosting
-
Gather the ingredients.
-
Combine the butter, sweetener, and cocoa powder in the bowl of a stand mixer fitted with the paddle attachment or in a large bowl with a hand mixer. Beat on medium speed until light and fluffy, about 3 minutes.
-
Add the vanilla, salt, and 2 tablespoons of the milk. Continue to beat until combined. If frosting is too thick, add 1 tablespoon of milk at a time until desired texture is reached.
-
Once the cake is cooled, frost and serve.
Recipe Tips
- To amplify the cocoa powder’s natural flavor and richness, add 2 teaspoons of espresso powder with the vanilla in the cake batter. Additionally, you can use espresso or coffee in lieu of the milk.
- If you want to lighten the cake slightly, you can add 1 to 2 tablespoons of apple cider vinegar to the batter once it is completely mixed together. This will help aerate the cake as it bakes, making large holes in the sponge.
