This chocolate sponge cake is the healthiest most delicious baked good you will find out there. No sugar, no flour and no butter or oil. It is the ultimate guilty pleasure, without the "guilty". The sweetness comes from the dates and bananas, and the consistency is achieved by using eggs and grounded almonds.
Preheat the oven at 180º.
Remove the stone from the dates and place them in a bowl with boiled water for 2-3 minutes, until softened.
Add the dates, bananas, cinnamon and water to a food processor, blend until creamy texture.
In another bowl, mix the almond flour, baking powder, baking soda and cocoa powder.
In a large bowl, whisk the eggs, then whip in the creamy date-banana mix; mix well.
Add the bowl with dry contents and add the crushed walnuts. Mix well.
Take a previously greased or baking-sheet covered loaf tin and add the cake mix. Bake in the oven for 35 minutes and then check with a fork or thin pin by pinching. If it comes out with mix on it, bake for another 1-2 minutes then check again. Once the pin/fork comes out clean, it is ready!
