Swiss Chocolat Frey Cake is a decadent chocolate cake that can be made with the assistance of a food processor. The food processor can be used to finely chop the chocolate for the cake batter. The batter is made by creaming butter and sugar together, then adding eggs, flour, cocoa powder, and the chopped chocolate. The cake is baked until moist and fudgy. Swiss Chocolat Frey Cake is a chocolate lover's dream and is often served with a dollop of whipped cream.
