Ingredients

  • 1 pkg. yellow cake mix
  • 2 Tbsp. water
  • 1/3 c. butter, softened
  • 1 egg
  • 4 c. miniature marshmallows
  • 1 pkg. peanut butter chips
  • 2/3 c. light corn syrup
  • 1/4 c. butter
  • 2 tsp. vanilla
  • 2 c. crisp rice cereal

Instructions

  1. In a mixing bowl, beat the cake mix, water, softened butter, and egg until blended. The batter will be thick.

  4. Sprinkle the baked layer with miniature marshmallows and bake for 2 minutes longer.
  5. Remove from oven and set aside to cool slightly.
  6. In a large saucepan, combine peanut butter chips, light corn syrup, and butter. Cook and stir over medium low heat until melted and smooth.

  8. Spread the peanut mixture over the marshmallow layer.
  9. Cool completely before cutting into bars with a sharp knife.

Tips & Substitutions

For a richer flavor, consider using brown butter instead of regular butter when making the peanut mixture. If you want a crunchier texture, you can add chopped peanuts or even a handful of pretzels to the crisp rice cereal. Ensure to keep an eye on the marshmallows while baking; they can burn quickly. These bars can also be made gluten-free by using a gluten-free cake mix.

Serving Suggestions

These Peanut Mallow Bars make a delightful snack on their own, but they pair beautifully with a glass of cold milk or a scoop of vanilla ice cream for dessert. You can also serve them at parties or gatherings, alongside other treats like Aunt Edna'S Apple Pie or Frozen Fudge Bars for a sweet spread. They are perfect for lunchboxes or as an after-school snack.

Storage & Reheating

Store leftover Peanut Mallow Bars in an airtight container at room temperature for up to a week. If you prefer, you can refrigerate them for a slightly firmer texture. To reheat, place them in the microwave for about 10-15 seconds to enjoy a gooey treat. Just be cautious not to overheat them, as the marshmallows can become too soft.

Frequently Asked Questions

Can I use a different type of cake mix for this recipe?

Yes, you can substitute the yellow cake mix with other flavors such as chocolate or vanilla. Just be aware that the flavor and color of the bars will change slightly, but they will still be delicious. Experimenting with different mixes can yield a fun variety!

What if I don’t have peanut butter chips?

If you're looking to make these bars a bit healthier, consider using natural peanut butter chips or reducing the amount of corn syrup. You could also try adding in some dried fruits like cranberries or raisins for added texture and flavor.

Can I freeze Peanut Mallow Bars?
