Ingredients You’ll Need

How to Make Funfetti Marshmallow Popcorn Treats (Step by Step)
Step 1: Prepare your popcorn
Pop the popcorn and remove any unpopped kernels. Place it in a large mixing bowl and set aside.
Step 2: Melt the marshmallow mixture
In a large saucepan, melt butter over medium heat. Add marshmallows and stir continuously until completely melted and smooth. Remove from heat and stir in vanilla extract.
Step 3: Combine and mix
Pour the melted marshmallow mixture over the popcorn. Gently stir until all the popcorn is evenly coated.
Step 4: Add the funfetti!
Let the mixture cool slightly (so the sprinkles don’t melt), then add rainbow sprinkles and any optional add-ins. Stir just until distributed.
Step 5: Shape or press
You can either:
- Press the mixture into a greased 9×13-inch pan for bars, OR
- Form into round popcorn balls using greased hands.
Step 6: Set and enjoy
Allow treats to cool for 30 minutes before cutting into squares or enjoying by hand.
Tips for the Best Marshmallow Popcorn Treats
- Use fresh popcorn – stale popcorn won’t stick well.
- Low heat = smooth marshmallows – prevents burning.
- Work quickly – the marshmallow mixture sets fast.
- Grease your hands – makes shaping balls easier.
- Cool before adding sprinkles – keeps colors bright.
- Add candy for crunch – M&Ms or pretzels are perfect.
- Use silicone spatula – it won’t stick to the gooey mix.
- Add extra marshmallows – for ultra chewy texture.
- Double the batch – they disappear fast!
- Store airtight – keeps them soft and fresh longer.
