Add candy melts to microwave safe bowl. Follow the directions on your candy melts bag for melting until chocolate is smooth, thin and glossy.
Place approximately 1 Tbsp of melted chocolate into each mold and use the back of a spoon to coat the sides.
After all sides are coated in each mold, pick up mold and tap on the surface until chocolate runs down the sides and fully coats the bottom.
Place molds in the refrigerator to harden for 5 minutes.
Remove molds and place oreo in the middle of each cup.
Pour remaining melted chocolate into each mold.
Pick up the mold and tap again until the chocolate appears to have coated the space between the cookie and the sides of the mold and evenly covered the top. Continue to tap on the counter until all air bubbles are gone.
Place back in the refrigerator for approximately 15 - 20 minutes or until the chocolate has fully hardened.
Remove cookies from each mold.
To make the ears, cut each marshmallow diagonally. Dip the sticky side into the sprinkles.
Re-melt any chocolate left in the bowl and place a small amount on the bottom of the marshmallow ears, candy eyes and m & m and stick to the oreo to create the bunny face.
