- ½ cup Karo syrup (light corn syrup)
- ⅓ cup water
- 5 oz mini marshmallows (about 3 cups)
- 1 cup creamy peanut butter
Directions
- Prepare popcorn
Place air-popped popcorn in a large bowl, removing any unpopped kernels. Set aside. - Make syrup
In a large nonstick saucepan over medium heat, melt the butter. Add sugar, corn syrup, and water. Stir and bring to a boil, cooking until the syrup reaches 235–240 °F (soft-ball stage), about 4–5 minutes. - Add marshmallows and peanut butter
Remove from heat, stir in mini marshmallows until melted, then add peanut butter and mix until smooth and creamy. - Coat the popcorn
Pour the warm peanut butter mixture over the popcorn. Stir gently until popcorn is evenly coated. - Cool and break apart
Spread coated popcorn on a parchment-lined or lightly greased baking sheet. Let cool completely at room temperature, then break into bite-sized clusters. - Serve or store
Serve in bowls or cups. Store leftovers in an airtight container at room temperature for up to 5 days.

Variations

- Spiced version: Add a pinch of cinnamon or cayenne pepper to the syrup for a warming kick.
Storage/Reheating

FAQs
1. Can I use microwave popcorn instead of air-popped?
Yes—just make sure to use plain, unsalted, unbuttered popcorn so the coating sticks properly.
2. Can I use natural peanut butter?
Natural peanut butter may yield a slightly looser coating. Stir well or add an extra 1–2 tablespoons to improve consistency.
3. Why use corn syrup?
Corn syrup helps create a smooth, chewy coating and prevents sugar crystallization.
4. Can I make this gluten-free?
Yes—popcorn and ingredients are naturally gluten-free. Just verify that your corn syrup and marshmallows are certified gluten-free.
5. Why heat to 235–240 °F?
This is the soft-ball stage: it ensures the coating sets properly without becoming too hard or sticky.
6. Can I double the recipe?
Yes—just double all ingredients and use a larger bowl for mixing and a bigger baking sheet for cooling.
7. How do I achieve bigger clusters?
Press the popcorn gently into the baking sheet after spreading to encourage larger clumps.
8. Can I add candy pieces?
Absolutely—mix in M&Ms or toffee bits once the popcorn has cooled slightly but before completely set.
9. Is this safe for kids?
Yes—it’s made with basic pantry ingredients. Let it cool completely to avoid burns.
10. Can I freeze the popcorn?
Yes—freeze in a sealed bag for up to a month. Thaw at room temperature before eating to retain crunch.
