Frost plain donuts in orange frosting, then add a pumpkin face for a Halloween party dessert.
Cut 1 doughnut into 11 small wedges. Press wedges into holes of remaining 11 doughnuts.
Tint frosting orange with icing color and heat 25 to 40 seconds in the microwave, until it's the consistency of heavy cream and thin enough to pour. Place 6 doughnuts on a cooling rack over parchment or wax paper. Evenly pour frosting over doughnuts to completely cover. Let cool 10 minutes, then transfer to a plate, using a spatula. Scoop icing from paper, reheat, and pour over remaining doughnuts to coat.
Place chocolate frosting in a freezer-weight zip-top bag and snip off a small corner. Pipe jack-o'-lantern faces on doughnuts. Cut and shape spearmint candies into stems and insert in tops. Refrigerate until ready to serve.
