I'm a bit late with the recipe as the last slices were eaten on Sunday:)
It is my simplified version of the Fudge Layer Cake from a very old Taste of Home magazine. Instead of making a layer cake with filling, I just baked a simple 1 level cake with frosting. I changed some ingredients and their amount, too. I used:
Ab. 1.5c flour (1 cup white + 1/2c flour mixture: spelt, buckwheat, corn) + 1/2c cocoa powder. (Together it makes 2 cups dry ingredients)
1tsp vanilla extract
Ab. 50g softened butter
Ab. 1 1/3 c brown sugar
1 tsp baking soda
Ab. 1c water
For frosting I used:
1pkg cream cheese
2 tbsp sugar
100g dark chocolate (75% cacao)
To make the cake, cream butter and sugar, add eggs and vanilla extract. Add the dry ingredients alternately with water. Pour into a baking pan and bake at 175*C for +/- 35 min.
For frosting, melt butter and chocolate together and stir into cream cheese, add sugar to taste. Spread over the cake and let it set. Store in the fridge. Enjoy!
