Mardi Gras Oreos

"These chocolate covered Oreo cookies are absolutely perfect for your Mardi Gras / Fat Tuesday party. They're dipped in white, then covered with the three Mardi Gras colors -- green, gold, and purple -- in candy melts. The candy melts in this recipe are hand piped, which is a lot easier to do than you might think. Don't let that deter you. If you really don't want to hand pipe, you can just drizzle the colors with a fork."
