Ingredients

Scale
  • For the Cookies:
  • 1 ½ cups old-fashioned rolled oats
  • 1 cup all-purpose flour
  • 1 teaspoon cinnamon
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ½ cup unsalted butter, softened
  • ¾ cup brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • For the Filling:
  • ½ cup unsalted butter, softened
  • 1 ½ cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1 tablespoon milk or heavy cream

Instructions

 

  1. Prepare the Cookie Dough:

    • In a bowl, whisk together the oats, flour, cinnamon, baking soda, and salt.

    • In another bowl, beat the butter and brown sugar until light and fluffy.

    • Add the egg and vanilla extract, mixing until well combined.

    • Gradually mix in the dry ingredients until just combined.

  2. Chill the Dough:

    • Cover and refrigerate the dough for about 30 minutes to prevent spreading.

  3. Bake the Cookies:

    • Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

    • Scoop small portions of dough and roll into balls. Place them on the baking sheet, leaving space between each.

    • Bake for 10-12 minutes, or until golden brown.

    • Let the cookies cool completely before assembling.

  4. Make the Filling:

    • Beat the butter, powdered sugar, vanilla extract, and milk (or cream) until light and fluffy.

  5. Assemble the Sandwiches:

    • Spread or pipe the filling onto the flat side of one cookie, then press another cookie on top to form a sandwich.

Notes

  • For softer cookies, slightly underbake them and let them cool on the baking sheet.
  • If you prefer a firmer filling, chill the assembled cookies for 30 minutes before serving.
  • Swap vanilla extract in the filling for maple extract for a unique twist.
