5 Ingredient Chocolate Peanut Bars (also called Mile-High Bars) are the perfect sweet treat. When you are craving chocolate, and want a touch of salt with it, the dry roasted peanuts add the right amount of salt and crunch. Marshmallows and butterscotch add great flavor to this rich, decadent chocolate dessert bar!

Mile High Bars

I've been making these yummy treats for many years. I was given the recipe from a coworker, and everyone I have shared them with loves them!

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.

You can get about 40 small pieces, or 20 larger pieces from this recipe. These tasty dessert bars are pretty rich, but you can cut them any size you want!

When I make these 5 Ingredient Chocolate Peanut Bars, I have to give a lot of them away. I like them a little too much! Haven't had any complaints!

This is a great recipe to make with kids. They will have fun helping to make and eat these delicious treats!

    These are delicious! I love the sweet with a little salt from the peanuts. My husband really enjoyed them too. This was easy to make so it will be a treat we make often!

      Hi Carrie! I'm glad that you and your husband enjoyed these! I also like that salty/sweet combo. The salt being very light makes it not overpower the other flavors. Thank you for your review!
