Ingredients (~24 squares)
- 2/3 cup (10 1/2 tbsp) unsalted butter, cubed
- 1 tsp vanilla extract
- 1/2 tsp fine salt
- 1 (16 oz) bag mini marshmallows
- 9 cups crispy rice cereal
- Flaky sea salt, for topping
Get the Pan Ready and Make Brown Butter
Grease a 9×13-inch baking pan with cooking spray or butter and line it with parchment paper, leaving an overhang on the sides so you can use it to lift out the treats later.
In a large saucepan or Dutch oven, melt the cubed butter over medium heat. Continue to cook, stirring frequently with a silicone spatula, until the butter foams and turns golden brown and nutty-smelling.
Watch it closely, as it can burn quickly.
Turn off the heat and immediately stir in the vanilla extract and fine salt. Be cautious, as the mixture will bubble and may splash.
Making the Marshmallows and Forming the Treats
Add the mini marshmallows to the hot brown butter and stir continuously until they are completely melted and the mixture is smooth.
Add the crispy rice cereal to the pot. Work quickly to fold and stir the cereal into the marshmallow mixture until it is evenly coated.
Transfer the warm mixture to the prepared pan. Lightly grease your spatula or your hands and press the mixture into an even layer. For softer, chewier treats, press lightly; for firmer, denser treats, press down more firmly.
Sprinkle the top evenly with flaky sea salt. Let the treats cool completely at room temperature for at least 1 hour before lifting them out of the pan and slicing into squares.
