Popcorn Cake Recipe
Introduction
Popcorn Cake is a fun and colorful treat that combines the crunch of popcorn with the sweetness of melted marshmallows and festive M&M’s. It’s perfect for parties or anytime you want a delightful snack that’s easy to make and sure to impress.

Ingredients
- ¾ cup salted butter
- 20 ounces mini marshmallows (two 10-ounce packages)
- 14 cups bagged pre-popped unflavored popcorn, kernels removed (microwave popcorn can be substituted)
- 2 cups plain M&M’s
Instructions
- Step 1: Lightly spray a 10-cup Bundt cake pan with nonstick cooking spray.
- Step 2: In a medium microwave-safe bowl, combine the butter and mini marshmallows. Heat on high in 30-second increments, stirring between each, until fully melted and smooth.
- Step 3: Place the popped popcorn in a large 6 to 7-quart bowl.
- Step 4: Pour the melted marshmallow mixture over the popcorn. Use a wooden spoon to gently stir until the popcorn is well coated.
- Step 5: Sprinkle in the M&M’s and gently fold them in, being careful not to smudge the colors.
- Step 6: Scoop the popcorn mixture into the prepared Bundt pan, pressing down gently as you fill it to help it hold together.
- Step 7: Let the cake rest at room temperature for 2 hours or until firm.
- Step 8: Carefully invert the popcorn cake onto a serving plate and cut into 12 slices.
Tips & Variations
- Use microwave popcorn without any added flavorings or butter for best results. If using flavored popcorn, it can affect the overall taste.
- Try colorful M&M’s or swap for chocolate chips or mini Reese’s pieces for different flavors.
- Press the mixture firmly into the pan to help the cake hold its shape better after setting.
Storage
Store the popcorn cake in an airtight container at room temperature for up to 2 days to maintain freshness and crunch. Avoid refrigeration as it can cause the marshmallow coating to harden. If it softens, you can gently reheat in the microwave for a few seconds to soften before serving.

FAQs
Can I use regular-sized marshmallows instead of mini marshmallows?
Yes, you can use regular marshmallows. Just chop them roughly into smaller pieces to help them melt evenly and coat the popcorn better.
What if I don’t have a Bundt cake pan?
You can use a similarly sized round or loaf pan lined with parchment paper. Just press the popcorn mixture firmly into the pan and allow it to set as directed.
