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.
If you have another type of cake, that is fine too. I mixed Chocolate cake ( from Barbie cake & vanilla Pink cake from the Stable cake) Crumble up all the cake in bowl.
Mixed the cake crumbled together.
Add a few spoons of buttercream frosting ( I had Pink vanilla buttercream left over from the stable cake).
Mix the buttercream with the crumbled by hand ensuring all the buttercream is mixed in.
Ball together a small amount of the mixture to see if it holds together, if not add some more buttercream until you get the mixture to form a ball.
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.
