Simply A (RD) Fact: Did you know that marshmallows are fat free? (but that doesn't mean that they are low calorie and should not be treated as a treat!)
  • 1 cup all-purpose flour
  • ½ cup oat bran
  • ½ teaspoon baking soda
  • ¼ teaspoon baking powder
  • ½ teaspoon salt
  • 1 stick unsalted butter, softened
  • ½ cup granulated sugar
  • ½ cup brown sugar, packed
  • 1 egg
  • 1 teaspoon vanilla
  • 1 cup chocolate chunks
  • 12 regular-sized marshmallows
  • Additional chocolate chunks for garnish
  1. Preheat your oven to 350 degrees. Grease a 9x9-inch baking pan with cooking spray and then line the bottom with a parchment paper sling. Create a parchment paper sling to line the pan. Cut two 9"x12" pieces of parchment paper. Lay each piece in the pan, ensure the bottom and sides are covered (one piece goes one way and the other piece goes the other). Clip excess parchment to the sides of the pan with binder clips. Set aside.
  2. In a small bowl, combine flour, oats, baking soda, baking powder, and salt. Whisk to combine.
  3. In the bowl of a stand mixer, combine butter, granulated sugar, and brown sugar. Beat until light and fluffy. Add in the egg and vanilla and beat until combine.
  4. With the mixer on low, add in the dry ingredients. Mix until just combined. Add in the chocolate chunks and mix until distributed.
  5. Portion out half the dough and press into the baking dish, leaving a ½-1 inch border (the cookies will spread!). Layer the marshmallows in a grid-like pattern (3 marshmallows by three marshmallows with the remaining marshmallows ripped in half and stuffed in the open areas) over the cookie dough. Then press the second half of the dough over the marshmallows, using your hands to make straight edges. Pop the baking dish into the preheated oven and bake for 20-25 minutes until the edges are golden and the middle is set.
  6. Let the cookies cool before cutting and serving. Enjoy!
