This red velvet Black Forest cake recipe is made with a food processor and is perfect for those who are looking for a unique twist on the classic recipe. The cake layers are made with a combination of flour, cocoa powder, and red food coloring, 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.
