Carefully place a lollipop stick in the middle of each Oreo. If the cookie breaks, gently press the cookie to the stick to make sure it holds together.
Place a piece of parchment paper or waxed paper on a table to place your dipped Oreo cookies on.
Place the candy melts in a microwave safe bowl. Heat in 20-30 second intervals, stirring well after each heating, until it is completely melted.
Take an Oreo pop and dip it into the candy melts, coating the cookie completely. Gently tap off the excess candy melts and place on the parchment paper. If using sprinkles or sanding sugar, quickly pour them on top of the Oreo.
Repeat with remaining Oreos.
If you want to make a drizzle heat another color of melts or chocolate in a microwave safe bowl then pour in a zip top baggie. Snip off the end and drizzle over top of the Oreo pops.
