After you crumble the cake up, mix in 1/2 cup of your favorite frosting or buttercream icing until it turns into a dough-like consistency.
Roll into 1 Tbsp or 2 Tbsp balls. Then, chill in the refrigerator for at least 2 hours.
Once they have chilled for 2 hours, dip your candy stick one at a time into the candy melts (melted) insert into the bottom of your cake ball. Now it's a cake pop! I wiped away any excess and I chilled them overnight before dipping them into candy melts.
A couple of things I learned and some tips:
Don't use a buttercream that has butter in it. I'm a huge fan of buttercream that has butter in it but it's not very useful for cake pops. The candy melts are really warm and draws out the butter in the buttercream. They still taste fine but aren't very attractive if you're using this as a present or a party favor at a baby shower. Use store bought icing or a buttercream that only has shortening in it.
I was not able to get the candy melts into a good consistency for dipping without adding vegetable oil to the melted candy melts. Don't be afraid, I think I even had to add at least 1/2 cup of oil even.
To get evenly sized cake pops, I used a Tablespoon measuring spoon to measure out cake "dough" before rolling into a ball.
When covering cake pops in sprinkles, I found dipping them proved to be too messy. Holding them over my bowl of sprinkles and using a spoon to drip the sprinkles over them worked best.
