Butterscotch Haystacks are an easy no-bake holiday treat made with butterscotch chips, creamy peanut butter, crunchy chow mein noodles, and roasted peanuts. Top them with mini M&M's for a pop of holiday color!
Place the butterscotch chips and peanut butter in a large microwave-safe bowl. Microwave in 30-second increments, stirring between each, until the chips melt and the mixture is smooth.
Stir in the chow mein noodles and peanuts.
Scoop heaping tablespoons of the mixture onto the prepared sheet pans. If using, sprinkle the mini M&M's over the tops right away.
Refrigerate for 15 to 20 minutes, or until set. Enjoy.
