Ingredients You’ll Need
Gathering your ingredients is the first step to making these delightful treats. The beauty of this popcorn bar recipe is its simplicity; you likely have most of the ingredients in your pantry already! Here’s what you’ll need to get started:
- 12 cups popped popcorn (about ½ cup unpopped kernels)
- 10 ounces marshmallows
- ¼ cup (½ stick) unsalted butter
- 1 teaspoon vanilla extract
- ½ teaspoon salt
- 1 ½ cups M&Ms
How to Make Simple Popcorn Bars with M&Ms

Now for the fun part! These easy popcorn treats come together in just a few simple steps. With a little bit of melting and mixing, you’ll have a batch of delicious bars ready to enjoy in no time. Let’s dive in!
Step 1: Pop the Popcorn
Start by popping your popcorn. You can use an air popper, pop it on the stovetop, or use microwave popcorn. Make sure you remove any unpopped kernels. Measure out 12 cups of popped popcorn and place it in a large bowl. This will be the base of your crispy popcorn squares.
For the best results, use freshly popped popcorn. It has the best texture and flavor. If you’re using microwave popcorn, be sure to check for any unpopped kernels. The texture is key for these homemade popcorn bars, so you want to ensure the popcorn is light and airy.
Step 2: Melt the Butter and Marshmallows
In a large saucepan, melt the butter over medium-low heat. Once the butter is melted, add the marshmallows and stir constantly until they are completely melted and smooth. This creates the sweet, gooey base that holds everything together. Be very careful not to burn the marshmallows.
Stirring constantly is the key to preventing burning. If you find the mixture is getting too thick, you can reduce the heat slightly. Once the marshmallows are melted, remove the saucepan from the heat and stir in the vanilla extract and salt. This step will add extra flavor to your popcorn snack bars.
Step 3: Combine the Ingredients
Pour the melted marshmallow mixture over the popcorn in the large bowl. Using a spatula, gently fold the popcorn and marshmallow mixture together until the popcorn is evenly coated. Be careful not to crush the popcorn. This step is about getting everything coated in that delicious marshmallow goodness.
Make sure every piece of popcorn is coated for the best texture and flavor. If you find it difficult to mix, you can lightly grease your spatula with cooking spray. This will help prevent the mixture from sticking. For a slightly different twist, you could try adding a swirl of creamed butter and sugar to the melted marshmallows.
Step 4: Add the M&Ms

Gently fold in the M&Ms. Don’t overmix, as you want to keep the candies intact. This is where the color and fun really come into play. The M&Ms add a burst of color and a delightful chocolatey crunch to your M&M popcorn bars.
For added flavor, you can use different varieties of M&Ms. Peanut M&Ms or even pretzel M&Ms would be delicious. If you prefer, you can reserve some of the M&Ms to sprinkle on top of the bars after they’re in the pan for a more visually appealing treat. If you like the taste of peanuts, you could also experiment with peanut butter popcorn bars.
Step 5: Press into a Pan
Lightly grease a 9×13 inch baking pan. Pour the popcorn mixture into the prepared pan and gently press it down to create an even layer. Don’t press too firmly, as you want to maintain the airiness of the popcorn. A light touch is key to the perfect texture of your popcorn candy bars.
You can use a spatula or your hands (lightly greased) to press the mixture into the pan. If you prefer a thicker bar, you can use a smaller pan. For a smoother surface, you can use a piece of parchment paper to press down the mixture. This will also help prevent the mixture from sticking to your hands. If you want to experiment with flavor, try using different types of sugar. You could even use a bit of brown sugar to add a bit of molasses flavor.
Step 6: Cool and Cut

Let the popcorn bars cool completely at room temperature. This will allow them to set. Once cooled, cut the bars into squares or rectangles. These dessert bars with popcorn are ready to serve and enjoy! Just be patient and let them cool, or they’ll be a sticky mess.
For clean cuts, use a sharp knife. You can also lightly grease the knife with cooking spray. Store the bars in an airtight container at room temperature. They should stay fresh for several days. If you’re looking for other popcorn bar variations, consider adding other candies, nuts, or even a drizzle of melted chocolate.
