Indulge in a delightful keto-friendly version of the classic black and white sponge cake. This recipe combines the richness of dark chocolate with the lightness of almond and coconut flour, resulting in a heavenly treat suitable for your low-carb lifestyle.
Ingredients: 6 large eggs, separated. 1/2 cup almond flour. 1/4 cup coconut flour. 1/2 cup erythritol or preferred keto-friendly sweetener. 1 tsp vanilla extract. 1/2 tsp cream of tartar. Pinch of salt. 3 oz unsweetened baking chocolate. 1/4 cup unsalted butter. 1/4 cup powdered erythritol or preferred keto-friendly sweetener. 1/2 cup heavy cream.
Instructions: Warm the oven up to 350F 175C and grease a 9-inch round cake pan. Mix the egg whites, cream of tartar, and salt in a large bowl. Beat the mixture until stiff peaks form. Put the egg yolks, erythritol, and vanilla extract in a different bowl. Beat them together until they are pale and creamy. Mix the almond flour and coconut flour into the egg yolk mixture very slowly until they are just combined. Be careful not to leave any white streaks when you fold the beaten egg whites into the egg yolk mixture. After getting the cake pan ready, pour half of the batter into it and smooth the top. Put the baking chocolate and butter in a heat-safe bowl and set it over a pan of simmering water. You can also do this in the microwave and stir the mixture until it is smooth. Add the heavy cream and powdered erythritol and mix until everything is well mixed. Spread the chocolate mix out evenly over the batter in the cake pan. Add the rest of the batter on top and smooth it out. Put it in the oven and bake for 25 to 30 minutes, or until a toothpick stuck in the middle comes out clean. Let the cake cool all the way in the pan before taking it out and cutting it. Serve and have fun!
