Ingredients Equipment Method Notes

Ingredients
  

  • 1 teaspoon high-quality vanilla extract
  • 6 cups Lucky Charms cereal approx. one standard 10.5 oz box
  • Pinch of sea salt optional, for garnish
  • Non-stick cooking spray or extra butter for greasing

Equipment

  • 9x9 inch baking pan
  • Parchment paper or aluminum foil
  • Large pot or Dutch oven
  • Silicone spatula or wooden spoon
  • Knife (for slicing)

Method
 

  1. Prepare the Pan: Line a 9x9 inch baking pan with parchment paper or aluminum foil, leaving an overhang on the sides for easy removal. Lightly grease the lining with butter or non-stick spray to ensure a clean release.
  2. Melt the Butter: Place a large pot or Dutch oven over low heat. Add the salted butter and allow it to melt gently until fully liquid and slightly bubbling. Do not rush this step to avoid scorching.
  3. Create the Marshmallow Base: Add the mini marshmallows to the melted butter. Stir continuously with a silicone spatula while keeping the heat on low until the marshmallows melt into a smooth, white sauce.
  4. Flavor the Mixture: Immediately remove the pot from the heat. Stir in the vanilla extract and a pinch of salt (if using) to enhance the flavor.
  5. Fold in the Cereal: Pour the Lucky Charms cereal into the pot. Work quickly to fold the cereal into the marshmallow mixture until every piece is evenly coated.
  6. Press and Set: Transfer the mixture into the prepared pan. Using a greased spatula or hands slightly wet with cold water, gently press the mixture into the corners. Do not pack it down tightly to keep the texture airy.
  7. Cool and Serve: Allow the treats to sit at room temperature for at least one hour to set. Use the parchment overhang to lift the block out of the pan, then slice into squares.

Notes

Texture Tip: Do not compact the mixture too hard in the pan, or the bars will become dense and hard. Sticky Hands Trick: If the mixture sticks to your hands while pressing, wet your fingers with cold water instead of using butter. Variations: For a nuttier flavor, brown the butter before adding marshmallows, or drizzle melted white chocolate over the finished bars. Storage: Store in an airtight container at room temperature for up to 3 days.
