Lay the Oreo cookie mold on a flat surface. In a small bowl, melt the milk chocolate wafers according to the package instructions. Be sure to stir every 30 seconds so that the chocolate doesn’t burn.
Fill each mold cavity halfway with the melted chocolate. Press an Oreo into the chocolate so that it’s submerged but doesn’t totally reach the bottom. Top each Oreo with chocolate to seal it shut. Lightly tap the mold onto a hard, flat surface to release any air bubbles.
Refrigerate the mold for at least an hour to make sure that the chocolate has set.
Once set, place a cutting board or plate onto a flat surface. Flip the mold over to release the Oreos. They may come out my themselves but if not, lightly press on the back of each one. The heat from your finger will release the cookie.
Melt a small amount of white chocolate according to the package directions. 1/4 cup should be enough!
Carefully add the Valentines decorations to the Oreos using the white chocolate as glue. Let them set for another 10-15 minutes and then they’re ready to eat!
