Hi Robi,
Here's a recipe I found, hope you enjoy!

BLACK FOREST CAKEYield: 16 ServingsBATTER

6 Egg
1/2 ts Salt
1 c Sugar
10 T Butter, unsalted; melted
1/2 c Flour
1 ts Vanilla
1/2 c Cocoa
3 T Kirschwasser
1 ts Baking powderFILLING AND FROSTING

1 pt Heavy cream; whipped
16 oz Cherry pie filling
1 T Kirschwasser
12 Glazed red cherries
2 T Sugar
1 Milk chocolate; bar or chunk

Preheat oven to 350 degrees. Grease two 9" layer-cake pans. In a large bowl, beat the eggs until thick. Gradually add sugar, beating constantly. Sift the flour, cocoa, baking powder, and salt together.
Carefully fold the dry ingredients into the egg mixture
alternately with the melted butter. Add vanilla. Pour into the pans and bake for about 25 minutes.
The center of the cake should feel firm to the touch. While still warm, sprinkle Kirschwasser over the
layers. Let set 10 minutes, then remove the layers from the pans to cool completely.

To the whipped cream, add the Kirschwasser and sugar. Spread half of the cherry filling over one layer of cake. Cover with a thin layer of whipped-cream mixture. Place the second layer of the cake on the
first. Spread with the remaining cherry filling and cover with whipped-cream mixture. Ice the sides of the cake with a thin layer of the whipped cream.Decorate around the top edge of the cake with rosettes of whipped cream. Put a glazed cherry in each rosette.

Make chocolate curls by shaving solid chocolate with a vegetable peeler. Sprinkle the chocolate on the top of the cake. Put a little chocolate on the sides of the cake if you wish.
