Ingredients:
- Tablespoons Unsalted Butter (85g)
- Cups Miniature Marshmallows (approx. 210g)
- Teaspoon Pure Vanilla Extract (5ml)
- Cups Puffed Rice Cereal (150g)
- /2 Teaspoon Flaky Sea Salt (2.5g)
- Extra Flaky Sea Salt for topping
Instructions:
- Line a 9x13 inch baking pan with parchment paper, ensuring an overhang on the long sides. Lightly grease the parchment.
- Melt the 6 Tbsp of butter in a large, heavy-bottomed saucepan over medium heat. Continue cooking, swirling frequently, until the butter foams, subsides, and small brown specks form at the bottom, releasing a nutty aroma (brown butter stage). Immediately remove from heat.
- Add 3 cups of the miniature marshmallows to the hot brown butter. Stir constantly over very low residual heat until almost completely melted and smooth.
- Remove the pan from the heat entirely. Stir in the vanilla extract and the ½ tsp of flaky sea salt until fully combined.
- Gently fold in the remaining 1 cup of marshmallows. Stir just until they are slightly softened and sticky but still holding some shape.
- Pour the 6 cups of puffed rice cereal into the marshmallow mixture. Using a rubber spatula, gently fold the cereal until evenly coated. Avoid overmixing to maintain airiness.
- Transfer the mixture to the prepared pan. Using lightly buttered hands or the back of the spatula (applying minimal pressure), gently press the mixture evenly into the pan.
- Immediately sprinkle the top evenly with extra flaky sea salt. Allow the treats to cool and set completely at room temperature for at least 1 hour before lifting out and slicing.
