Chop up the cake remnants in a bowl, add the jam or jelly, then mix in the cocoa powder, add amaretto if you like, but be careful, it should still remain a malleable mass. Mix everything together and form about 10 golf ball-sized balls.
Then roll in chocolate sprinkles and put in paper cases. Finished!
They taste best when they have been in the refrigerator for a night. Then they are more solid and beautiful.
