In a small pot or bowl, melt the chocolate chips. Stir it frequently and be careful not to burn it. Add food coloring if you want. I’m going to leave it white for now.
Let the melted chocolate cool for 30 seconds to a minute then pour it into a piping bag and cut off the tip.
Fill the bottom of the mold with a thin layer of melted chocolate. Tap the mold gently against the work surface to spread the melted chocolate. Put the Oreos on top of the melted chocolate. Refrigerate for 1-2 minutes.
Take the mold out. Fill the rest of the mold until it’s covered. Refrigerate for about 15 minutes or until hardened.
When the chocolate is hardened, pop out the Oreos.
