How to Make Marshmallow Popcorn
Step 1: Prepare Your Popcorn
Start by popping 7 cups of your favorite popcorn. Freshly popped is best for a light, crunchy base. Make sure to remove any unpopped kernels to avoid surprises while munching.
Step 2: Melt the Butter and Marshmallows
In a large pot over low heat, melt 3 tablespoons of butter. Once melted, slowly add 50 marshmallows and stir constantly until they’re completely smooth and sticky. This creates the luscious marshmallow sauce that will coat your popcorn perfectly.
Step 3: Add Vanilla and Protein Powder
Stir in 1 teaspoon of vanilla extract and 1 scoop of cake batter protein powder. These ingredients enhance both the flavor profile and texture, giving the marshmallow mixture a subtle sweetness with a fun cake-like twist.
Step 4: Combine With Popcorn
Pour the fluffy popcorn into a large mixing bowl and immediately drizzle the marshmallow mixture over it. Use a spatula or wooden spoon to gently fold everything together until the popcorn is evenly coated with that gooey, sweet goodness.
Step 5: Add the Funfetti Sprinkles
Sprinkle generously with funfetti sprinkles while the marshmallow mixture is still warm so they stick well. This adds a burst of colorful personality and a tiny bit of crunch.
Step 6: Let it Set
Spread the Marshmallow Popcorn out on a baking sheet lined with parchment paper to cool and set. Once it has firmed up slightly, you’re ready to dive in!
How to Serve Marshmallow Popcorn

Garnishes
To elevate your Marshmallow Popcorn, consider garnishing with a pinch of flaky sea salt to contrast the sweetness or drizzle with melted white chocolate for an extra decadent touch. Fresh fruit slices on the side can balance the rich flavors beautifully.
Side Dishes
This treat pairs surprisingly well with light, refreshing sides like crisp apple slices or a chilled berry bowl. If serving at a party, consider an assortment of nuts or cheese cubes to bring complementary textures and flavors.
Creative Ways to Present
Package your Marshmallow Popcorn in colorful paper cones or glass jars with festive ribbons for a charming gift. Layer it with chocolate chips and crushed cookies in a clear container for a visually stunning sweet snack mix that everyone will adore.
Make Ahead and Storage
Storing Leftovers
Keep your Marshmallow Popcorn fresh by storing it in an airtight container at room temperature. It should stay tasty and chewy for up to three days, perfect for nibbling over a few afternoons.
Freezing
If you want to make a big batch ahead of time, freezing is a great option. Place popcorn in a sealed freezer bag or container, and it will keep well for up to a month. When ready, thaw at room temperature before serving.
Reheating
To enjoy warm, slightly gooey Marshmallow Popcorn again, pop it in the microwave for about 10 seconds. This softens the marshmallow coating just enough without making the popcorn soggy.
FAQs
Can I use different types of popcorn for Marshmallow Popcorn?
Absolutely! While plain, lightly salted popcorn works best, you can experiment with kettle corn or flavored popcorn for interesting variations. Just be mindful of balancing sweetness.
Is there a way to make this recipe dairy-free?
Yes! Substitute the butter with a dairy-free alternative like coconut oil or vegan margarine, and make sure your marshmallows are gelatin-free and vegan-friendly.
Can I add other mix-ins besides funfetti sprinkles?
Definitely! Chopped nuts, mini chocolate chips, or dried fruit pieces make delicious additions. Just fold them in after coating the popcorn with the marshmallow mixture.
How do I prevent the marshmallow mixture from hardening too quickly?
Work quickly once the marshmallows are melted to combine with the popcorn, and keep your mixing bowl warm if possible. This keeps the mixture pliable and easier to spread evenly.
Is cake batter protein powder necessary?
While it adds a unique flavor and a protein boost, you can omit it if you don’t have any on hand. The Marshmallow Popcorn will still be delicious with just the basic ingredients.
