    • 2 large eggs
    • 4 grams pure vanilla extract
    • 180 grams all-purpose flour
    • 6 grams baking soda
    • 3 grams ground cinnamon
    • ¼ teaspoon ground nutmeg
    • ¾ teaspoon kosher salt
    • 150 grams old-fashioned oats, uncooked
    • 134 grams quick oats, uncooked
  • For the Cream Filling:

    • 226 grams powdered sugar
    • 369 grams marshmallow fluff (1 jar)

Directions:

  1. Preheat the oven to 375°F and prepare two 8×12-inch baking pans with nonstick spray and parchment paper overhang.
  2. In a stand mixer, cream together the butter and sugars until creamy. Add eggs and vanilla, beating well.
  3. In a separate bowl, whisk together the flour, baking soda, cinnamon, nutmeg, and salt. Add to the wet mixture and beat until incorporated.
  4. Mix in the oats until combined. Divide the dough between the prepared pans and spread evenly.
  5. Bake for 12-13 minutes until golden brown. Do not over-bake.
  6. While the bars bake, prepare the cream filling by beating together softened butter, powdered sugar, marshmallow fluff, vanilla, and salt until fluffy.
  7. Once baked, transfer the bars to a cooling rack to cool completely.
  8. Spread the cream filling over one cooled cookie bar, then top with the other bar. Freeze for at least 2 hours or overnight before slicing into bars.

Notes:

  • For a twist, try adding chopped nuts or dried fruit to the oatmeal cookie dough.
  • Store leftover bars in an airtight container in the refrigerator for up to 5 days or freeze for longer storage.
