Want to use food coloring? I'd suggest using the candy melts instead of white chocolate for the coating. I wasn't impressed with how the white chocolate took the food coloring. It made the chocolate thicker.I purchased all of my ingredients including the cake pop sticks and sprinkles at Target. The styrofoam I had already, but you can get a block of styrofoam at crafts stores or Walmart.
The recipe (using only 1/2 of a 9 X 13 cake) makes about 13 medium sized cake balls.
Feel free to change up the cake, frosting and coating. Red velvet cake, with cream cheese frosting and white chocolate coconut, is really good!
You can also use homemade cake and homemade frosting but I seriously can't tell the difference in taste.
