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!
