I like to use whatever my child brings home; however, I am strategic in the flavor pairings. I know my kids don't like coconut so I don't put any almond joys in the skillet. Nor do I put any peanut m&m's for choking reasons. But honestly… the sky is the limit. Here is what I put in my cookie skillet. -Hershey Miniature Chocolate Bars -Kit Kat Bars -Reese's Peanut Butter Cups -M&M's -Milk Dud's
