Once you try this Sweet and Crunchy Popcorn Cake with M&M’s Recipe, I think you’ll find yourself reaching for it again and again. Let me walk you through it, and I’ll share my best tips to make sure it turns out perfectly every time.

Ingredients You’ll Need

This recipe is all about simple, recognizable ingredients that come together beautifully without much fuss. Each one plays a critical role—whether it’s texture, flavor, or the magic binding everything together. Here’s what you’ll want to have on hand before we dive in.

  • Salted butter: Adds richness and helps melt the marshmallows smoothly; don’t skip the salted kind—it balances the sweetness perfectly.
  • Mini marshmallows: Key for that gooey, sticky texture that binds the popcorn; mini-sized melts faster and distributes more evenly.
  • Pre-popped popcorn: Using bagged, unflavored popcorn saves you time and ensures your popcorn isn’t too oily or salty.
  • Plain M&M’s: They add that colorful crunch and chocolate burst; plain ones work best so the flavors don’t compete.

Variations

One of my favorite parts about making this Sweet and Crunchy Popcorn Cake with M&M’s Recipe is how easy it is to personalize. I often switch it up depending on the occasion or who I’m sharing it with—don’t be shy about making it yours!

  • Use peanut butter M&M’s: Adds a nutty flavor and extra texture, which I tried at a kid’s birthday once, and it was a huge hit.
  • Swap marshmallows for a vegan option: Try vegan marshmallows to make this treat more inclusive; I did this for a friend’s party and the results were just as delightful.
  • Mix in nuts or pretzels: For extra crunch and saltiness, I like stirring in some crushed pretzels; it adds a wonderful contrast.
  • Add drizzled chocolate or caramel: For a more decadent touch, especially around holidays—I do this at Christmas for an extra festive vibe.

How to Make Sweet and Crunchy Popcorn Cake with M&M’s Recipe

Step 1: Melt the Butter and Marshmallows Together

Start by melting your salted butter over low heat in a large pot or microwave-safe bowl. Once melted, add the mini marshmallows and stir continuously until they’re completely melted and silky smooth. If you’re doing this on the stove, keep the heat low to avoid burning and use a rubber spatula to scrape the sides as you stir.

Step 2: Combine Popcorn and M&M’s

In a big mixing bowl, add your pre-popped popcorn and plain M&M’s candies. Give it a quick stir so they’re nicely mingled. The volume can be a bit intimidating—14 cups is a lot! But trust me, the marshmallow mixture will coat everything evenly once added.

Instructions

  1. Prepare the Butter and Marshmallow Mixture: In a large saucepan over low heat, melt the ¾ cup of salted butter. Once melted, add the 20 ounces of mini marshmallows and stir continuously until the marshmallows are completely melted and the mixture is smooth.
  2. Combine with Popcorn: Remove the saucepan from heat and immediately add the 14 cups of pre-popped, unflavored popcorn. Stir thoroughly to coat all the popcorn evenly with the marshmallow butter mixture.
  3. Add M&M’s: Gently fold in 2 cups of plain M&M’s, ensuring they are evenly distributed without crushing the candies.
  4. Shape the Cake: Lightly grease a large bowl or mold and transfer the popcorn mixture into it. Using a spatula or clean hands (lightly greased with butter or cooking spray to prevent sticking), press the mixture firmly together to form a compact cake shape.
  5. Cool and Set: Allow the popcorn cake to cool at room temperature for about 30 minutes until firm and set. Optionally, place it in the refrigerator for an additional 10-15 minutes for easier slicing.
  6. Slice and Serve: Carefully remove the popcorn cake from the mold, slice into wedges or squares as desired, and serve immediately.

Notes

  • Use fresh popcorn to avoid any stale flavors and to ensure crispness.
  • Greasing your hands or utensils when pressing the mixture prevents sticking.
  • Store leftovers in an airtight container at room temperature for up to 2 days to maintain freshness.
  • Feel free to substitute M&M’s with other colorful candies or chocolate chips.
  • This recipe is a no-bake, stovetop preparation focused on melting and mixing.
