Ingredients

Scale

Makes about 12 pies

  • For the cookies:
    • 1 cup (230 g) unsalted butter, softened
    • 3/4 cup (150 g) brown sugar, packed
    • 1/2 cup (100 g) granulated sugar
    • 2 large eggs
    • 1 teaspoon vanilla extract
    • 1 1/2 cups (190 g) all-purpose flour
    • 1 teaspoon baking soda
    • 1 teaspoon ground cinnamon
    • 1/4 teaspoon salt
    • 3 cups (240 g) quick oats
  • For the cream filling:
    • 1/2 cup (115 g) unsalted butter, softened
    • 1 cup (125 g) powdered sugar
    • 1 teaspoon vanilla extract
    • 1 (7 oz / 200 g) jar marshmallow fluff

Instructions

  1. Preheat the oven:
    • Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
  2. Make the cookie dough:
    • In a large mixing bowl, cream the butter, brown sugar, and granulated sugar together until light and fluffy, about 2-3 minutes.
    • Beat in the eggs one at a time, followed by the vanilla extract.
    • In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Stir in the quick oats.
  3. Bake the cookies:
    • Scoop the dough into 1 1/2 tablespoon-sized balls and place them on the prepared baking sheets, spacing them about 2 inches apart.
    • Flatten the tops slightly with the back of a spoon or your fingers.
    • Bake for 10-12 minutes, or until the edges are lightly golden and the centers look set. Allow to cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
  4. Prepare the cream filling:
    • In a medium bowl, beat the butter until creamy. Gradually add the powdered sugar and mix until smooth.
    • Beat in the vanilla extract and marshmallow fluff until fully combined and fluffy.
  5. Assemble the cream pies:
    • Pair the cooled cookies by size. Spread or pipe a generous layer of the cream filling onto the flat side of one cookie. Top with the matching cookie to create a sandwich.
  6. Serve and enjoy:
    • Serve immediately or store in an airtight container at room temperature for up to 2 days or in the refrigerator for up to a week.

Notes

  • Use quick oats for a softer texture; old-fashioned oats will make the cookies chewier.
  • Freeze assembled cream pies for up to 3 months and thaw at room temperature before serving.
  • For added flavor, stir a pinch of cinnamon or a drizzle of honey into the cream filling.
