Caramelized Brown Butter Rice Krispies Treats

Step 1

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

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.

Step 3

When butter is evenly browned, stir in marshmallows. (If using unsalted butter, stir in 1/8 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.

Step 4

Turn off heat, add cereal, and mix well, preferably with a silicone spoon or a spatula. Scrape into prepared pan (either 9x13 for thick pieces or a cookie sheet with a rim for thinner pieces) and press down lightly. If necessary, butter hands to press mixture flat. Let cool, and cut into squares or bars.
