I made up this recipe after quitting grains and my daughter requested marble cake for her birthday. Marble cake is a popular cake in Germany, where people regularly eat cake as an afternoon snack. It's sort of like the English tea time. Only in Germany they call it "coffee and cake".
3 cups almond flour
3 tbsp tapioca flour
2 tsp baking powder
5 tbsp honey
2 tbsp unsweetened cocoa powder
1 tbsp vanilla extract
1/3 cup melted coconut oil
Preheat oven to 285F.
Add 4 eggs into a bowl, separate 5 eggs, and add egg yolks to the 4 eggs. Mix with an electric handmixer. Add in almond flour, tapioca flour, baking powder, honey, vanilla extract, and melted coconut oil and mix well until you have a nice batter.
Beat egg whites until peaks form.
Pour half the batter into separate bowl, and fold in half of the egg whites gently.
Add the unsweetened cocoa powder to the other half of the batter, mix it well.
Fold other half of egg whites into the chocolate batter.
Pour the chocolate batter into a greased bundt cake form. Pour the white batter on top. Use a fork to create a marbling effect. (For this birthday cake, I actually put layers of chocolate and white on top of each other.)
Bake for one hour, remove from the oven and turn over within a few minutes.
