Brown Butter Rice Crispy Treats aren't your average Rice Krispies treats; I am taking this childhood favorite to a whole new level with the rich, nutty flavor of brown butter.
In a large pot, melt the unsalted butter over medium heat until it begins to brown, starts to smell nutty, and shows some brown bits at the bottom, stirring frequently. This usually takes about 5 minutes. Be careful not to burn it.
Once the butter is browned, reduce the heat to low and stir in the milk powder. Cook for another minute, stirring constantly, until the milk powder is fully incorporated and slightly toasted.
Once the butter and milk powder are browned, turn off the heat and stir in the salt and vanilla extract until well combined.
Add the mini marshmallows to the pot. Turn the heat back on low, stirring constantly until the marshmallows are completely melted and the mixture is smooth.
Once the marshmallows are fully melted, turn off the heat and add the remaining marshmallows. Fold only a couple of times.
Add the Rice Krispies cereal. Stir until the cereal is fully coated with the marshmallow mixture.
Quickly transfer the mixture to the prepared 20x20 cm (8x8 inch) baking pan with parchment paper. Use a spatula to press the mixture evenly into the pan. Be careful not to press too hard, as this can make the treats too dense.
Allow the treats to cool completely at room temperature, for about 1 hour.
Once cooled, use a sharp knife to cut the treats into squares.
Serve and enjoy brown butter rice crispy treats!
