Ingredients Equipment Method Notes

Ingredients
  

  • 6 cups Lucky Charms cereal
  • 3 tablespoons unsalted butter
  • 1 pinch fine sea salt

Equipment

  • 8x8 or 9x9 inch baking dish
  • Large heavy-bottomed pot
  • Sturdy silicone spatula or wooden spoon
  • Parchment paper (optional)
  • Measuring cups and spoons
  • Sharp knife

Method
 

  1. Lightly grease an 8x8 or 9x9 inch baking dish with butter or non-stick spray. Optionally, line it with parchment paper for easy removal.
  2. In a large, heavy-bottomed pot, melt the butter over low heat.
  3. Once the butter is melted, add all the mini marshmallows and the pinch of salt. Stir constantly until the marshmallows are completely melted, smooth, and glossy (3-5 minutes).
  4. Immediately remove the pot from the heat.
  5. Quickly pour in the 6 cups of Lucky Charms cereal. Gently but swiftly fold the cereal into the melted marshmallow mixture until every piece is evenly coated.
  6. Immediately transfer the mixture to the prepared baking dish.
  7. Lightly grease your hands or the bottom of a measuring cup and press the mixture firmly and evenly into the pan.
  8. Allow the treats to cool at room temperature for 1-2 hours until completely set and firm. For a faster set, refrigerate for about 45 minutes.
  9. Once fully set, use a sharp knife to cut into squares. Wipe the knife clean between cuts for neat bars.

Notes

Use low heat to melt the marshmallows to prevent scorching or a tough texture. Greasing your spatula and hands prevents sticking. For best texture, use fresh cereal; if stale, toast at 300°F for 5 minutes to crisp. Store in an airtight container at room temperature for up to 3 days. Variations: Add 1 tbsp sprinkles and 1/2 tsp vanilla extract; drizzle with melted chocolate; or add 1/4 cup peanut butter to the melted butter and marshmallows.
