How to make
Peel the apples and grate them. Mix them with the cinnamon. Sift the flour with the baking powder in a bowl and add the oil, sugar, eggs, vanilla and beat well.
Finally mix the apples and walnuts in. Pour half of the mixture into a greased and floured cake pan. Beat the other half with the cocoa and chocolate, then add it to the rest.
Put the cake with apples and chocolate to bake in a pre-heated oven at 360°F (180 °C) until ready.
