Brown butter rice krispie treats transform the childhood classic into a gourmet gem, bursting with rich, nutty caramel notes and a touch of salty magic.
Brown butter in a saucepan over medium low heat, stirring occasionally. Once butter starts to bubble, turn off the heat and allow it to cook with the residual heat for a couple more minutes.
You want it to kind of caramelize, but not burn. Stir in the mini marshmallows (minus 2 cups that you’ve set aside), the condensed milk, and vanilla extract.
