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.
Colorful Swirl Cookies - These are sweet sugar cookies which are surprisingly easy since they are a slice and bake cookie. Yes, aside from making the dough and rolling it together, this is just as easy as going to Shoprite for some Pilsbury's sugar cookie dough, but it's so much better!
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.
