Variations of this Recipe
For this recipe I used M&Ms and chocolate chips however you can totally change up the candy to what you have on hand.
Chocolate Bars. Candies like Milky way, Kit Kats, Hershey’s Bars, Reese’s cups and really any chocolate bar you can think of can be chopped up and used in place of the chocolate chips and M&Ms in this cookie recipe. Just toss the candy into a food processor and give it a quick pulse to chop them up.
I tend to make these after the kids have gone trick-or-treating because we have such a large variety of candies that we can use to change things up when making these cookies.
Peanut butter. I use creamy peanut butter when making these cookies but you can also use crunchy peanut butter if you want to.
Change up the chocolate chips! Peanut butter chips, butterscotch chips, white chocolate chips, semi-sweet chocolate chips, and milk chocolate chips all work well.
