Ingredients

Scale

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

  1. Prepare the pan: Lightly spray a 10 cup Bundt cake pan with nonstick cooking spray to prevent sticking.
  2. Melt butter and marshmallows: In a medium microwave-safe bowl, combine the butter and mini marshmallows. Heat on high in 30 second increments, stirring between each, until the mixture is fully melted and smooth.
  3. Add popcorn: Place the 14 cups of popped popcorn into an extra large bowl (6 to 7 quarts) for mixing.
  4. Combine marshmallow mixture with popcorn: Pour the melted marshmallow and butter mixture over the popcorn. Use a wooden spoon to gently stir until the popcorn is evenly coated.
  5. Add M&M’s: Sprinkle in the 2 cups of plain M&M’s. Stir very gently to avoid smudging the candy colors.
  6. Press into pan: Scoop the coated popcorn mixture into the prepared Bundt cake pan, pressing down gently to compact the mixture evenly.
  7. Set the cake: Let the popcorn cake rest at room temperature for 2 hours or until firm and set.
  8. Serve: Carefully turn the popcorn cake out onto a serving plate and slice into 12 pieces. Enjoy!

Notes

  • Using microwave popcorn is a quick substitute but ensure kernels are removed for texture.
  • Be gentle when mixing in M&M’s to keep the colors vibrant and prevent smudging.
  • Make sure the popcorn cake is completely firm before slicing to avoid crumbling.
  • This cake is best served the same day but can be stored in an airtight container at room temperature for 1-2 days.
  • You can also customize by using different colored candies or adding nuts for crunch.
