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 and to ease cake removal later.
  2. Melt Butter and Marshmallows: In a medium microwave-safe bowl, combine the butter and both packages of mini marshmallows. Heat on high in 30-second increments, stirring between intervals until fully melted and smooth.
  3. Add Popcorn: Place the pre-popped popcorn into an extra large (6 to 7 quarts) bowl, ensuring there’s enough room to mix thoroughly.
  4. Combine Mixture: Pour the melted marshmallow and butter mixture over the popcorn, stirring gently with a wooden spoon to evenly coat all popcorn pieces without crushing them.
  5. Add M&M’s: Sprinkle in the plain M&M’s, stirring very gently to avoid color smudging and to distribute evenly through the popcorn mixture.
  6. Shape in Pan: Scoop the coated popcorn mixture into the prepared Bundt pan, gently pressing down as you add more to compact the cake for better shape retention.
  7. Set the Cake: Allow the popcorn cake to rest at room temperature for 2 hours or until it becomes firm and holds together well.
  8. Serve: Carefully invert the Bundt pan onto a serving plate and cut the cake into 12 slices for serving.

Notes

  • Using plain M&M’s prevents color bleeds but you can try other candy types if desired.
  • Microwave cooking times may vary; stir marshmallows frequently to avoid burning.
  • Pressing the popcorn firmly in the pan helps the cake hold its shape better.
  • Store any leftovers in an airtight container at room temperature up to 2 days.
