Place the red candy melts and pink candy melts in microwave safe bowls. Heat them each on defrost mode for 1 minute at a time, stopping to stir in between, until they are completely melted.
Dip the bottom half of each regular sized Oreo cookie into either the pink melted candy or the red. Set the dipped Oreos on a wax paper lined cookie sheet, and allow the candy to harden.
Open the mini Oreo cookies, and remove the icing from the middle. Place one mini Oreo cookie half on each side of the larger candy dipped Oreos. Press the mini Oreos into the top of the regular sized Oreos gently so you do not break them. These will be Minnie and Mickey’s ears.
Once dry, use white cookie icing to draw a straight line cross the center of each cookie overlapping the place where the cookie has been dipped in the candy.
Allow the cookie icing to harden, and store the cookies in an airtight container, or serve immediately.
