Ingredients Method Notes

Ingredients
  

Main Ingredients
  • 10-12 cups Popped popcorn Plain, no butter topping from a bag
  • 1 stick Butter For melting and greasing
  • 10 ounces Mini marshmallows They melt fast and smooth
  • 1/2 cup Brown sugar or light corn syrup Depending on your preference
  • 1 teaspoon Vanilla extract
  • 1 pinch Salt
  • Optional mix-ins Sprinkles, crushed pretzels, mini chocolate chips, peanuts

Method
 

Preparation
  1. Pop your popcorn and remove any unpopped kernels.
  2. Grease your bundt pan or 9-inch round pan really well.
  3. In a pot, melt the butter, then add the mini marshmallows and stir until smooth.
  4. If you are using brown sugar or syrup, add it to the melted mixture and stir until glossy.
  5. Turn off the heat, then stir in the vanilla and salt.
  6. Pour the hot mixture over the popcorn in a large bowl and fold gently until coated.
  7. Press the mixture into the greased pan with lightly greased hands. Do not pack it too tightly.
Setting and Serving
  1. Let the popcorn cake set for 30 to 60 minutes.
  2. Once set, flip it out of the pan and slice to serve.

Notes

For best results, use plain popcorn. Avoid high heat when melting the mixture. Cool slightly before adding chocolate chips to prevent them from melting completely. Store in an airtight container at room temp to retain crunchiness.
