  4. In a large sauce pan combine the white chocolate chips, butter, and sweetened condensed milk. Stir until melted and creamy.
  5. Add the marshmallow cream and stir until melted. Use a toothpick to add a little green gel color until it is the desired green color of your choice. Pour on top of the cooled brownies.
