Ingredients
  

Ingredients
  • ¾ cup sweetened condensed milk divided
  • ¼ cup butter melted & cooled slightly
  • ¼ cup milk
  • 1 box brownie mix
  • 1 large egg white lightly beaten
  • Cooking spray
  • 7 oz marshmallow crème
  • ¾ cup peanut butter morsels

Equipment

  • Stand Mixer

Method
 

Directions
  1. In a large bowl, combine ¼ cup of the sweetened condensed milk, melted butter, milk, brownie mix and egg white. The batter will be thick.
  2. Spray a 9x13-inch baking dish with cooking spray. Spread ⅔ of the brownie batter into the bottom of the pan (it helps to use a spatula sprayed with cooking spray). The layer will be thin.

Bake the base:
 Bake for 10 minutes at 350°F.

  1. In a small bowl, stir together the remaining ½ cup sweetened condensed milk with the marshmallow crème and peanut butter morsels. Mix until smooth.
  2. Spread the marshmallow mixture evenly over the partially baked brownie layer. Carefully drop the remaining brownie batter by spoonfuls over the marshmallow layer.

Final bake: 
Return to the oven and bake for 30-35 minutes at 350°F, until the top looks set and slightly crackly.

  1. 
Let cool completely before cutting into squares. These are rich and gooey, so smaller portions work best!
