Prepare and bake brownies according to the package directions.
When the brownies are finished baking, turn off the oven and pull out the brownies.
Top them with the marshmallows, cover the pan with foil, and return to the warm oven for about 5-10 minutes or until marshmallows are puffed and melted.
Drizzle marshmallows white chocolate and top with sprinkles.
Allow brownies to cool completely before cutting and serving.
