Caramelized Brown Butter Rice Krispies Treats

Preparation

1. Step 1

   Line rimmed sheet pan with parchment paper or wax paper, or butter it well.

2. Step 2

   In a large pot, melt butter over medium-low heat. It will melt, then foam, then turn clear golden and finally start to turn brown and smell nutty. Watch closely and stir often.

3. Step 3

   When butter is evenly browned, stir in marshmallows. (If using unsalted butter, stir in ⅛ teaspoon salt.) Melt and cook, stirring often, until mixture turns pale brown, then stir constantly until lightly browned but not dark, 3 to 5 minutes.

4. Step 4

   Turn off heat, add cereal, and mix well, preferably with a silicone spoon or a spatula. Scrape into prepared pan and press down lightly. If necessary, butter hands to press mixture flat. Let cool, and cut into squares or bars.
