A Sweet Snack

  • Super easy ingredients likely already on hand, plus room for extras, popcorn bars become a new recipe every time you make them! So many ideas!
  • Whip up a double batch and freeze the bars for backpack and briefcase snacks, road trips, and picnics!
  • Variations galore! Create a popcorn bar station and use up leftover bits and pieces of chocolate, candies, crushed cookies, or nuts from other recipes.

Ingredients and Variations

Popcorn – Freshly popped popcorn is the lightest and fluffiest, but a bag of store-bought always works. Look for popcorn in a variety of colors, too!

Marshmallows – Cut large marshmallows into quarters if you don’t have minis. A 7-ounce jar of marshmallow fluff can be used in place of minis as well (plus it melts faster)!

Pretzels – Pretzels bring the crunch, but cereals like KIX, Chex, or even crushed cookies are fun to try! Even homemade granola will add some healthy crunch!

Candy – Mini M&M’s are sweet and colorful! We also like crushed toffee bits, caramel pieces, peanuts, chocolate chips, or crushed candy canes for a festive, holiday twist!

Variations – Swirl in your favorite nut butter, some caramel sauce, or even a bit of Nutella in Step 3, if you like.

How to Make Popcorn Bars

  1. Combine popcorn, pretzels, and half the M&M’s in a large bowl.
  2. In a saucepan, melt the remaining ingredients (per recipe below).
  3. Pour marshmallow mixture over the popcorn and toss to combine.
  4. Press into prepared pan and top with remaining M&M’s. Cool before cutting.

Tips for Success

  • Air poppers or microwave popcorn poppers make oil-free popcorn that prevents it from collapsing when it’s combined with the other ingredients.
  • Place a piece of plastic wrap over the bars when pressing them into the pan. Or, for kiddos, have them place their hands into sandwich baggies so they don’t get too sticky!

Storing Popcorn Bars

Keep leftover popcorn bars in a covered container at room temperature for up to 4 days or cut and freeze bars on a baking sheet. Once frozen, wrap pieces in plastic wrap and transfer to a zippered bag. Freeze for up to 4 weeks.
