With a heart shape silicon mold just place a peppermint in each cup and bake at 250 for about 20 minutes until the peppermint has melted into the heart shape. Cool and pop out of mold. I found my silicon heart mold at my local thrift store for $1 and you can purchase a bag of peppermints at the Dollar Store.
