  • 1 boxed brownie mix

  • 1/2 cup fluff

  • 1/2 cup smooth, peanut butter

  • 1/2 cup nutter butter cookies, crushed


  • Prepare the brownie mix according to the directions on the box. I used Ghirardelli mix – it’s my favorite!
  • Pour the brownie mix in a 9″ x 9″ greased pan fit with parchment paper.
  • Scoop the fuff one tablespoon at a time all over the top of the brownie mix. Repeat this step with the peanut butter.
  • Use a toothpick to swirl the peanut butter and fluff around the top of the brownie mix until it is evenly distributed.
  • Crush the nutter butters then sprinkle on top of the brownies.
  • Bake according to the directions on your box. Allow the brownies to cool in the pan before slicing.
  • Enjoy!
