Ingredients
Below are the main ingredients you’ll need. Exact measurements are listed in the recipe card further down.
- Popped popcorn (about 6–10 cups, depending on the recipe version)
- Unsalted butter
- Regular or jumbo marshmallows (mini marshmallows work well too)
- Vanilla extract
- Funfetti sprinkles
- Optional: melted white chocolate, peanut butter, a pinch of salt, cake mix or protein powder for variations

How to Make
- Pop the popcorn: Pop your kernels using your preferred method (stovetop, microwave, or air popper). Remove any unpopped kernels and measure out the popped popcorn.
- Melt the marshmallows: In a large saucepan, melt butter over low heat, then add marshmallows and stir until smooth and fully melted.
- Flavor the mixture: Remove from heat and stir in vanilla extract. If using a cake mix or protein powder for flavor, add it now and combine well.
- Combine with popcorn: Pour the melted marshmallow mixture over the popcorn and gently toss with a rubber spatula until the popcorn is evenly coated.
- Add sprinkles: Stir in the funfetti sprinkles, folding gently so they distribute without melting from the heat.
- Shape the treats: Transfer the mixture to a parchment-lined baking dish or sheet pan. Press it firmly into an even layer using a spatula or lightly greased hands.
- Optional drizzle: Melt white chocolate and drizzle over the top for an extra decorative touch. Add additional sprinkles if desired.
- Cool and serve: Let the treats firm up at room temperature for about 30 minutes, then cut into squares or break into clusters.

Storing Leftovers
Store leftovers in an airtight container or zip-top bag in a cool, dry place away from direct heat and sunlight. At room temperature they stay fresh for 2–3 days. Refrigerating can extend storage up to a week but may reduce crunchiness.
Tips and Tricks
- Use fresh popcorn: Freshly popped popcorn provides the best texture. Remove any unpopped kernels before mixing.
- Coat evenly: Use a large bowl and a rubber spatula to ensure the marshmallow reaches every piece.
- Work quickly: The marshmallow mixture sets fast, so have everything ready before you melt it.
- Cool completely: Allow the treats to set fully before cutting to maintain clean edges and a firm texture.
- Chocolate drizzle: Let any melted chocolate cool and set before cutting to avoid smudges.
- Customize freely: Swap sprinkles, add mix-ins like mini chips or nuts, or experiment with flavored extracts.

FAQs
Can I use microwave popcorn?
Yes. Microwave popcorn is a convenient option — just be sure to remove any unpopped kernels before combining with the marshmallow mixture.
How should I melt the marshmallows?
Melt them gradually over medium-low heat in a saucepan, stirring continuously until smooth to prevent burning.
Can I add other mix-ins?
Absolutely. Mini chocolate chips, chopped nuts, or dried fruit make excellent additions for extra flavor and texture.
