Packed with rich butterscotch and peanut flavor and fluffy marshmallows, Butterscotch Marshmallow Bars Recipe is an easy, no-bake dessert snack bar.

Butterscotch Marshmallow Bars Recipe

This is a classic dessert snack bar. It reminds me a lot of Payday candy bars. Coincidently, my favorite growing up!

They are always a crowd-pleaser and great for potlucks, parties, and tailgating since they’re dense and travel well. As well, you can make them in about 5 minutes. (I don’t recommend them if it’s super hot since the butterscotch will melt.)

Although these bars are loaded with butterscotch chips, peanut butter, and peanuts they are overly sweet because of the marshmallows. The marshmallows are so great texture to an otherwise dense bar.

There are just six ingredients in this recipe.

  • Butterscotch chips. If you think you’re not a butterscotch lover, give these bars a chance. Added to the peanut butter, they’re not overly butterscotch-y. I used these Butterscotch Chips.
  • Creamy peanut butter. You can actually add creamy or crunchy peanut butter so go with whatever you have on hand. However, I don’t recommend natural peanut butter. I just love this Simply Jif.
  • Butter. Use real butter, not margarine for this recipe.
  • Mini marshmallows. You can use traditional minis or rainbow minis.
  • Peanuts. I love really salty peanuts in this recipe!
  • Cereal. You can add Cheerios, Chex, or Rice Krispies cereal. As well, you can omit the cereal and add another cup of peanuts. Alternately, you can add shredded coconut for the cereal if you prefer.
