Popcorn Cake 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

Prepare the Pan: Lightly spray a 10-cup Bundt cake pan with nonstick cooking spray to ensure easy removal of the cake once set.
Melt Butter and Marshmallows: In a medium microwave-safe bowl, combine the butter and mini marshmallows. Heat on high in 30-second intervals, stirring between each, until the mixture is completely melted and smooth.
Mix Popcorn: Place 14 cups of pre-popped popcorn into a very large bowl (6 to 7 quarts) to accommodate mixing.
Combine Melted Mixture with Popcorn: Pour the melted butter and marshmallow mixture over the popcorn. Using a wooden spoon, gently stir until the popcorn is evenly coated.
Add M&M’s: Sprinkle 2 cups of plain M&M’s over the coated popcorn. Stir very gently to avoid smudging or melting the candy colors.
Fill the Bundt Pan: Scoop the coated popcorn mixture into the prepared Bundt cake pan, pressing down gently as you fill to pack the mixture firmly.
Set the Cake: Allow the popcorn cake to rest at room temperature for 2 hours or until it firms up and holds its shape.
Serve: Carefully invert the popcorn cake onto a serving plate. Cut into 12 slices and serve immediately for a fun and festive treat.

Notes

Use plain M&M’s instead of peanut or other varieties to prevent color bleeding and textural issues.
Microwave popcorn works as a convenient substitute for pre-popped popcorn; just be sure to remove all un-popped kernels.
Press the mixture gently into the Bundt pan to maintain the structure without crushing the popcorn too much.
For best texture, consume the popcorn cake within a day or two, as moisture can make it soggy over time.
Nonstick spray or lightly buttering the Bundt pan prevents sticking and helps in easy removal.
