Bake brownies according to package directions in 9x13 pan. Allow to cool.

Meanwhile in a medium bowl mix marshmallow crème and cream cheese together.

Once brownies are cool use a round cookie cutter or glass to cut circles from the pan of brownies.

30 minutes before serving mix berries and sugar together in a small bowl.

Create the brownie pizzas by layering the crème and then the berries onto each brownie circle or allow your guests to create their own
