Ingredients
- 6 tbsp unsalted butter
- 10 oz mini marshmallows
- 6 cups crispy rice cereal
- 1 cup marshmallow fluff
Instructions
- Step 1: Line a 9x13-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
- Step 2: In a large saucepan over low heat, melt 6 tbsp unsalted butter until fully melted and foamy.
- Step 3: Add 10 oz mini marshmallows to the melted butter and stir continuously until completely melted and smooth, about 3-4 minutes.
- Step 4: Remove the saucepan from heat and immediately fold in 6 cups crispy rice cereal, stirring gently until every piece is coated.
- Step 5: Transfer the mixture to the prepared pan and press evenly using a greased spatula or wax paper to avoid sticking.
- Step 6: Spread 1 cup marshmallow fluff evenly over the top layer, then use a kitchen torch or broiler (watch closely) to toast the marshmallow fluff until golden brown spots appear, about 1-2 minutes.
- Step 7: Let the bars cool completely at room temperature for 1 hour before lifting out using the parchment overhang and cutting into squares.
