This classic Black Forest cake recipe is made easy with the help of a food processor. The cake layers are made with a combination of flour, cocoa powder, and ground almonds, which are then mixed with eggs, sugar, and butter in the food processor. The cherry filling is made by cooking fresh cherries with sugar and kirsch, and the whipped cream frosting is made by whipping heavy cream with sugar and vanilla extract. The cake is then assembled by layering the cake, cherry filling, and whipped cream frosting, and topped with chocolate shavings and fresh cherries.
