Ingredients in Monster Munch

• ¼ cup unsalted butter
• 2 tablespoons corn syrup
• ¾ cup granulated sugar
• ½ teaspoon salt
• ½ cup creamy peanut butter
• ½ teaspoon vanilla extract
• 4 cups popped popcorn
• 1½ cups salted peanuts
• 4 cups Corn Chex or Rice Chex cereal
• 1 cup Halloween M&M’s (or other small chocolate candies)
• 1 cup semisweet chocolate chips

See the instructions below for how to combine these ingredients into a sticky, crunchy snack mix.

How to Make Monster Munch Halloween Chex Mix

1. Line a large rimmed baking sheet with parchment paper. Spread the popped popcorn evenly across the sheet, then scatter the salted peanuts and Chex cereal over the popcorn.

2. In a small saucepan over medium heat, melt the butter. Stir in the granulated sugar and salt until the mixture is smooth.

3. Bring the butter and sugar mixture to a low boil, reduce heat to medium, and stir in the corn syrup. Allow the mixture to boil gently for about 4 minutes, stirring occasionally so it doesn’t scorch.

4. Remove the saucepan from the heat and stir in the vanilla extract and creamy peanut butter until fully combined and smooth.

5. Pour half of the warm peanut butter caramel over the popcorn, peanuts, and cereal on the baking sheet. Toss gently to coat the mix evenly.

6. Drizzle the remaining peanut butter caramel over the mixture and stir again until the cereal and popcorn are well coated.

7. Let the mixture sit for about 5 minutes to cool slightly. Then sprinkle on the Halloween M&M’s and semisweet chocolate chips—waiting a few minutes prevents the candies from melting into the warm caramel.

8. Once cooled and slightly set, break apart any large clumps and transfer to a serving bowl. Serve at room temperature.

Substitutions and Dietary Options

This recipe is flexible. For gluten-free needs, use certified gluten-free cereal and gluten-free chocolate candies. Replace semisweet chocolate chips with white chocolate morsels or dark chocolate chips if you prefer. Dairy-free or vegan alternatives for chocolate and peanut butter are available and work well.

If you want to omit peanuts or peanut butter, skip the peanut butter in the caramel, omit the peanuts, and use an alternative spread such as sunflower seed butter (if no allergy concerns) or simply make a plain caramel drizzle. Cereal swaps like pretzels, Cheerios, or other crunchy crackers are also tasty options.

Variations and Mix-In Ideas

Monster Munch is meant to be customized. Add Honey Nut Cheerios, pretzels, candy corn, candy pumpkins, mini marshmallows, chopped Oreos, Reese’s Pieces, gummy worms, or candy eyes for a spooky look. For a seasonal twist, drizzle melted orange or colored candy melts over the cooled mix to change the theme color.

Equipment Needed

• Small saucepan (or double boiler) for the caramel mixture
• Large rimmed baking sheet lined with parchment paper or a very large mixing bowl
• Large spoon or spatula for stirring and tossing

Storing Monster Munch Snack Mix

Store Monster Munch in an airtight container to keep it fresh. For best texture and flavor, enjoy within three days at room temperature. If you prefer to keep it longer, refrigerate for up to five days—note that chilling can change the texture slightly.
