Ingredients

For the Oatmeal Cookies:

  • 1 cup (2 sticks) unsalted butter, softened
  • 1 cup brown sugar, packed
  • ½ cup granulated sugar
  • 2 large eggs
  • 1 tablespoon molasses
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon cinnamon
  • 1 ½ cups quick oats

For the Cream Filling:

  • ½ cup (1 stick) unsalted butter, softened
  • 1 ½ cups powdered sugar
  • 1 teaspoon vanilla extract
  • 2 tablespoons heavy cream or milk
  • ½ cup marshmallow fluff

Instructions

  1. Preheat Oven & Prepare Baking Sheets – Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

  2. Make the Cookie Dough – In a large bowl, beat together butter, brown sugar, and granulated sugar until light and fluffy. Add eggs, molasses, and vanilla, mixing until combined.

  3. Combine Dry Ingredients – In a separate bowl, whisk together flour, baking soda, salt, and cinnamon. Gradually add dry ingredients to the wet ingredients, mixing until just combined. Fold in quick oats.

  4. Bake the Cookies – Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing them about 2 inches apart. Bake for 8-10 minutes, or until edges are lightly golden. Let cookies cool completely.

  5. Make the Cream Filling – In a medium bowl, beat butter until smooth. Gradually add powdered sugar, vanilla, and heavy cream, beating until fluffy. Fold in marshmallow fluff.

  6. Assemble the Cream Pies – Spread or pipe filling onto the flat side of one cookie, then top with another cookie, pressing gently.

  7. Serve & Enjoy – Let the oatmeal cream pies set for a few minutes before serving. Store in an airtight container at room temperature for up to 3 days.

Notes

  • For softer cookies, slightly underbake them and allow them to cool on the baking sheet.
  • You can substitute molasses with maple syrup for a slightly different flavor.
  • If the filling is too thick, add an extra tablespoon of heavy cream or milk to loosen it.
