They are really quite simple to make. All you need is one box of cake mix (with the required ingredients), tub of frosting & bag of candy melts, such as Wilton which can be purchased in cake decorating section at craft store.
First, make a cake mix according to package. Let cool. Then crumble to pieces in a mixing bowl. I use a potato masher to do the crumbling.
Then add in one tub of frosting. Mix well. I used Butter Cream but will use cream cheese next time. Butter Cream works just fine and tastes great but I want to compare since Bakerella's site says to use cream cheese.
Once it's mixed well roll into balls and place on a wax lined cookie sheet. Place in the fridge for a few hours or in the freezer for at least 30 minutes until firm.
Once the cake balls are firm melt the chocolate in the 30 second increments. Use a spoon to roll the balls in the chocolate and place on the lined sheet to dry. They dry pretty fast.
