Turn mints into a serving tray! Just arrange on a cookie sheet lined with parchment paper, and bake at 350 for 8-10 minutes. Then let completely cool at room temperature. After your party, break and keep in a candy jar! Great idea for a plate of cookies you don't have to get back.
Candy Cane heart shaped lollipop. Could do this for valentines, Xmas Christmas yule, anniversary, or even a birthday if they really like peppermint. Just bake at 300F for 3 minutes, then quickly shape like a heart around a lollipop sucker stick. You could fill the suckers with white chocolate and sprinkles too, but I like just the plain candy cane sucker hollow in the middle.
