Roll white rolling fondant on a clean working surface until it’s about ¼ of an inch thick.
Use a paring knife to trace out the size of the rice cereal treats on the fondant - cut out 12 fondant rectangles.
Press one fondant rectangle on each rice cereal treat. Set aside.
Divide the pink fondant in 12 spheres, about ½ an inch in diameter each.
Roll each pink fondant sphere into 3 inch strips. Fold in half and twist, pointing each one at the end. These will act as your unicorn’s horns.
Insert a toothpick at the bottom of each unicorn horn.
Insert one unicorn horn at the top of each rice cereal treat.
Draw two eyelids (with eyelashes, of course!) on each rice cereal treat.
Attach Wilton icing tip #32 on the pink decorating frosting and frost each unicorn treat - just below the unicorn horn, on the corners, along the edges, etc.
Sprinkle the frosted portions with multi-colored nonpareils. Enjoy the unicorn magic!
