These Christmas Rice Krispie squares are festive and would look great on a holiday baking tray! Extra marshmallows and brown butter take these squares to another level! Just like ones you would find in a bakery!
Place butter in a large saucepan over medium heat. Cook the butter until it has melted and starts turning brown and smells nutty, a few minutes. Remove from heat.
Mix the reserved mini marshmallows in next. I like to put the saucepan back over low heat and stir until the mini marshmallows have softened slightly. Do no let them melt completely.
Spoon the mixture into the reserved baking dish and press it down evenly with a piece of parchment paper. Allow it to sit until hardened, about 1 hour.
