As for the rest of the cake, you want:
2 cups sour cherries
3 Tbsp cherry jam
8 cups of whipped cream
5 tsps Kirschwasser (cherry schnaps, which you can buy at your local liquor store)
1/4 cup chocolate shavings
Bake your cake and cool.
When assembling your cake spread the jam on the bottom layer and cover it with cherries (except the center part of about 1 and 1/2 inches). Cover with whipped cream (about 3/4 inch thick). Put the next layer of cake on top of that and sprinkle the Kirschwasswer evenly. Cover with another 3/4 inch of whipped cream and place the last layer on top. Cover the whole cake with the remaining whipped cream and decorate with chocolate shavings. Mark the top of the cake with a cake slicer. Put whipped cream in a pastry tube with a star decorator tip and squeeze little curls on each piece. Decorate each one with cherry on top of the curls.
And there you have it. Enjoy and don't weigh yourself after eating!
