How to make
Beat the eggs with the sugar, until a thick mixture is obtained.

The butter is melted. Cut the chocolate into small pieces. The mashed bananas and melted butter are added to the egg mixture.
In another bowl, put the dry ingredients, pre-sifted flour, cocoa, baking powder, soda, salt and ground walnuts.
