No-bake dessert bars are more popular than ever. In the summer, it’s nice to be able to make a decadent treat without turning on the oven. And without having to use a lot of stuff.

Mile-High Bars are simple, but they taste AMAZING! The 5 ingredients are Chocolate chips, butterscotch chips, peanut butter, mini marshmallows, and dry roasted peanuts.
