Cindy gives a hint with this recipe: Buy two bags of candy so you can have some leftover to eat as you unwrap for the recipe!
1 package brownie mix (your choice)
1 package chocolate mint candy (like York Peppermint Patties)
Mix the brownies according to package directions. Five minutes before baking time is up, top with mint candies. Return to the oven to melt. Swirl melted candy; cool and serve.
