When you have left over cake tops and some buttercream frosting the best thing to do is make some cake balls. They are a lovely little treat.
Crumble up the cake using your hands.
Make small balls with all the mixture and set aside.
Melt some chocolate in a pyrex microwave safe bowl ( Chocolate cake covering works well as dries quicker.)
Using a flattish spoon place a ball on the spoon.
Dip and roll the ball in the chocolate covering the entire ball.
Place the chocolate covered ball on a baking sheet. The cake covering chocolate dries quickly, so if you want to add some sprinkles you will need to do this quickly.
Continue this with all the remaining balls.
Allow to dry for about 10-15 mins and remove from the paper. You can trim of the excess chocolate.
Enjoy
