Ingredients

FOR THE COOKIES:

  • 2 cups quick cooking oats
  • 1 ½ cups all-purpose flour
  • 2 teaspoons corn starch
  • 1 teaspoon baking soda
  • ¾ teaspoon fine sea salt
  • ¼ teaspoon ground cinnamon
  • 1 cup room temperature, unsalted butter
  • ½ cup light brown sugar, packed
  • ½ cup granulated sugar
  • 2 large eggs
  • 2 tablespoons molasses
  • 1 teaspoon pure vanilla extract

FOR THE FILLING:

  • ½ cup room temperature, unsalted butter
  • 7 ounces marshmallow fluff
  • 2 cups powdered sugar
  • 1 teaspoon pure vanilla extract
  • Generous pinch of fine sea salt

Instructions

MAKE THE COOKIES:

  • Preheat the oven to 350°F and have ready a baking sheet lined with either parchment paper or a silicone baking mat.
  • Add oats, flour, cornstarch, baking soda, salt, and cinnamon to a food processor and pulse until oats are fine crumbs. Set aside.
  • Add butter, brown sugar, and granulated sugar to a large bowl and use a handheld mixer to mix on medium-high speed for about 3 minutes or until light and fluffy. Add eggs, one at a time, mixing after each addition. Next, add the molasses and vanilla. Mix once more.
  • Add dry ingredients and mix on low until combined.
  • Drop generous tablespoon-sized batter on the prepared baking sheet 2” apart, and bake for 10-12 minutes. Remove the cookies from the oven, and after about 10 minutes, transfer them over to a cooling rack to cool completely.

MAKE THE FILLING:

  • Add the butter, marshmallow fluff, powdered sugar, vanilla extract, and sea salt to a medium-sized mixing bowl and begin mixing on low speed. When the ingredients appear mostly combined, increase the speed to medium-high and mix until smooth.

ASSEMBLE THE COOKIES:

  • Turn half of the cookies bottom-side up and add a generous tablespoon of filling to the center. Top with the remaining cookies and press down gently until the filling reaches the edges of the cookies.
  • Allow to set for 1-2 hours, serve, and enjoy!
