Thanks to my best aunt mhkitty8880 i learned how to make cake balls!!!!   
here's how we make them:
1. Cook a cake in the oven.
2. Crumble the cake
3. Mix it with 1/4 - 1/2 of a tub of frosting with a blender
4. Make into a shape then chill 30 minutes
5. Dip in melted chocolate and harden. you can add sprinkles before hardening.

I have put them in the mini cupcake liners for seasonal parties and my aunt mhkitty8880 has made them look like cupcakes and put lollipop sticks in the center of the bottom before hardening. 

I'm sorry i cant find any pics of them but as soon as i find them i will add them!!!!
