Start by melting your wafers in a microwave, double boiler, or chocolate melting pot.
While the chocolate is melting, separate the sections of the mini Oreos and scrape off the cream filling.
Carefully insert the mini Oreo halves into the larger Oreos in the shape of Mouse ears. You'll want to slightly open the big Oreos to slip the miniature versions in. Be careful not to crack the Oreos when you press the sandwich back together.
A whole plate of chocolate Mickeys
Once your wafers are melted and smooth, dip the bottom half of each Oreo in, imitating Mickey's "pants."
As soon as each Mickey is dipped, cover the chocolate half with sprinkles or other toppings.
Lay the treats onto a cookie sheet lined with parchment paper or wax paper while they harden for a few hours. You can speed up the finishing time by putting the tray into the refrigerator if you like.
Once the chocolate has hardened into a shell, you can add buttons or other details with icing. Get creative!
