This low-fat Black Forest cake recipe is made with a food processor and is perfect for those who are looking for a healthier option. The cake layers are made with a combination of flour, cocoa powder, and applesauce, which are then mixed with egg whites, 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 low-fat yogurt 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.
