Ingredients for Monster Munch Marshmallow Popcorn Snack Mix
To make your very own Monster Munch Trail Mix, here are the ingredients you’ll need. This recipe creates enough to serve a crowd, so be prepared to share—or enjoy it all yourself!
For the Marshmallow Coating:
- 1 stick of unsalted butter
Butter forms the base of the marshmallow coating, giving it a rich flavor and smooth texture. - 1 cup light brown sugar
Brown sugar adds a delicious caramel-like flavor that perfectly complements the marshmallows. - 2 tablespoons light corn syrup
Corn syrup helps to create the glossy texture that holds the coating together. - 12 large marshmallows
These marshmallows melt down to create the sweet, gooey marshmallow coating. - 1 teaspoon vanilla extract
Vanilla enhances the sweetness of the coating and adds a warm, comforting flavor. - 1 teaspoon sea salt
A touch of sea salt helps balance the sweetness and adds flavor to the mix. - ½ teaspoon ground cinnamon
Cinnamon adds a touch of spice to the mix, making it feel cozy and perfect for fall.
For the Mix:
- 8 cups popped popcorn
Air-popped popcorn works best in this recipe because it’s light and crispy, giving the mix its base texture. - 2 cups mini pretzels
Pretzels add a salty crunch that pairs beautifully with the sweet marshmallow coating. - 2 cups cereal of choice
I used cinnamon Life cereal for a bit of extra flavor, but you can use any cereal you like. Cheerios, Rice Krispies, or even fruity cereal work wonderfully. - 1 cup salted nuts of choice, lightly chopped
I used peanuts in this mix, but feel free to swap them out for cashews, almonds, or walnuts. - 1 cup mini marshmallows
These add little bursts of sweetness and chewy texture throughout the mix. - 1 cup M&M’s (Halloween-colored ones are perfect!)
M&M’s are the perfect candy for adding a pop of color, sweetness, and crunch. - ½ cup candy corn or candy corn pumpkins
A Halloween favorite, candy corn adds color and a sweet, chewy texture. - A couple of tablespoons of Halloween-themed sprinkles
These sprinkles make the mix extra festive and fun, perfect for Halloween parties or spooky movie nights.
How to Make Monster Munch Marshmallow Popcorn Snack Mix
Now that you have all your ingredients, let’s get started! This recipe is easy to follow and takes just about 15 minutes to prep and assemble.
Step 1: Make the Marshmallow Coating
- Melt the butter: In a medium saucepan, melt the unsalted butter over medium heat.
- Add sugar and syrup: Once the butter is melted, add the brown sugar and corn syrup. Stir constantly until the mixture is fully combined and the sugar has dissolved (about 2 minutes).
- Melt the marshmallows: Add the marshmallows to the saucepan and stir until they completely melt into the butter and sugar mixture. This should only take a couple of minutes.
- Add vanilla, salt, and cinnamon: Once the marshmallows have melted, remove the saucepan from the heat and stir in the vanilla extract, sea salt, and cinnamon. This is the marshmallow coating that will make your snack mix so delicious!
Step 2: Prepare the Popcorn Mix
- Mix dry ingredients: In a large bowl, combine the air-popped popcorn, pretzels, cereal, and nuts.
- Spread on baking sheets: Spread the popcorn mixture out in an even layer on two large baking sheets lined with parchment paper. The parchment paper helps prevent the mix from sticking to the baking sheets.
Step 3: Coat the Mix with Marshmallow Mixture
- Pour the marshmallow coating: Carefully pour the marshmallow coating over the popcorn mixture. Be sure to drizzle it evenly so that every piece gets a good coating.
- Toss the mix: Using a spatula, gently toss the mix until everything is evenly coated. The popcorn and pretzels should be nicely coated in the gooey marshmallow mixture.
Step 4: Add the Fun Stuff
- Add candy and sprinkles: Once the popcorn mix has cooled slightly but is still warm, add the mini marshmallows, M&Ms, candy corn, and sprinkles. Gently toss everything to make sure these fun additions stick to the warm mixture.
- Let it cool: Allow the mix to cool completely before storing or serving. The marshmallow coating will firm up a bit as it cools, giving it a chewy, satisfying texture.
How to Store Your Monster Munch Trail Mix
This recipe makes quite a bit of mix, so you’ll need to store it properly to keep it fresh. Here’s how:
- Airtight container: Store your Monster Munch Marshmallow Popcorn Snack Mix in an airtight container to prevent it from getting stale. It should stay fresh and gooey for up to a week.
- Cool, dry place: Keep the container in a cool, dry place, such as a pantry or cupboard. Avoid storing it in the fridge, as this can cause the mix to harden.
Customizing Your Monster Munch Recipe
One of the best things about this recipe is that it’s incredibly customizable! Here are some ideas for making it your own:
- Cereal swap: If you’re not a fan of cinnamon Life cereal, try Cheerios, Rice Krispies, or any other cereal you like. You can even use granola for a slightly healthier twist.
- Different nuts: Experiment with different nuts, such as cashews, almonds, or pecans. If you prefer a nut-free mix, you can skip them entirely or replace them with dried fruit like raisins or cranberries.
- Candy alternatives: If you don’t have candy corn or M&Ms, try using chocolate chips, peanut butter cups, or even crushed-up candy bars. Dried fruit, like chopped apricots or cranberries, also makes a great addition.
