Gently open and remove the icing from a handful of Mini OREO cookies with a knife.
Make Minnie and Mickey's ears by using frosting as glue to stick the mini cookies inside of the larger cookies. Let frosting completely dry before decorating.
Melt red candy melts in the microwave for 30 seconds and stir. Repeat until candy is smooth and creamy.
Dip one half of a cookie into the melted candy, gently shake cookie to smooth any rough edges and place on a piece of wax paper to cool and harden.
For Christmas Sprinkle Cookies: Dip into a bowl of Christmas themed candy sprinkles before the red candy hardens.
Add Minnie's bow by placing a small bit of white frosting on the candy bow and gently sticking it on top of the cookie.
Decorate more Christmas themed cookies as you like, serve and enjoy!
