This is the BEST recipe for Rice Krispie treats! The secret is to brown the butter first. This adds so much nuttiness and richness and is really what sets them apart from store-bought Rice Krispies squares. A quick, no-bake dessert that everyone will love!
Gently grease a 9x13 baking dish with butter, then line the bottom with parchment paper.
Melt the butter in a large pot over medium heat. Once the butter is melted, let it cook for another 3 to 4 minutes. The butter should start to turn golden brown, and little brown specks will form at the bottom. Immediately add the marshmallows and stir until melted. Stir in the vanilla extract and salt, then remove from the heat.
Add the Rice Krispies cereal and mix until combined. Transfer the mixture to the baking dish and gently flatten it with a rubber spatula (or wet your hands with warm water). Allow the Rice Krispies to set in the fridge for 60 minutes before cutting and eating.
