Equipment

Ingredients
  

FOR GIANT COOKIES

  • 2 cups butter room temperature
  • 6 tablespoons molasses
  • 1 ½ cup dark brown sugar
  • 1 cup granulated sugar
  • 2 teaspoons baking powder
  • 2 teaspoons baking soda
  • 2 teaspoons salt
  • 4 eggs
  • 4 cups flour
  • 6 cups quick cooking oats

FOR MARSHMALLOW CREME FILLING

  • 5 cups powdered sugar
  • 6 cups marshmallow creme
  • 2 cup butter room temperature
  • ¼ cup milk

Instructions
 

  • Divide the ingredients in half to make two batches. Preheat the oven to 350°F. Spread parchment on two round baking sheets.
  • In the bowl of a stand mixer, cream together butter, molasses, brown sugar, and granulated sugar with the baking powder, baking soda, and salt.
  • On low speed, gradually add the flour, about 1/4 cup at a time. Alternate adding the eggs and flour, mixing until well combined. Gradually mix in the oats, 1/2 cup at a time, until a thick dough forms. If the dough sticks to the bowl, add more flour or oats as needed.
  • Prepare a large round baking sheet with parchment. Transfer the dough to the sheet and use a spatula to flatten it, leaving about 3-4 inches of space around the dough. The cookie will spread as it bakes.
  • Bake for 25-35 minutes or until golden brown and just starting to crack in the center. While the first cookie bakes, prepare and bake the second cookie following the same steps listed above.
  • Allow both cookies to cool completely on the baking sheets, then chill for one hour or until firm.
  • For the filling, in a large bowl, beat together powdered sugar, butter, and marshmallow creme using a hand mixer until crumbly. Gradually add milk, a teaspoon at a time, until the frosting is thick yet spreadable. Adjust milk as necessary.
  • To assemble, flip one cookie to be the bottom of the sandwich. Spread the frosting nearly to the edges, then top with the second cookie, pressing gently to spread the frosting evenly.
  • Cut into large slices or, for a fun twist, pretend to use a shrink ray to reduce the cookie to a manageable size. Enjoy your gigantic oatmeal creme pie!
