Ingredients

Scale

Cookie Dough

  • 1 cup Unsalted butter (room temperature)
  • 1 cup Brown sugar (packed, light or dark)
  • 1/2 cup White granulated sugar
  • 1 tsp Pure vanilla extract
  • 1/2 TBSP Molasses (not blackstrap)
  • 2 Large eggs (room temperature)
  • 1 3/4 cups All-purpose flour
  • 1 tsp Baking soda
  • 1 tsp Salt
  • 1 tsp Ground cinnamon
  • 1/2 tsp Pumpkin pie spice (or nutmeg)
  • 3 cups Old fashioned oats

Filling

  • 1 cup Unsalted butter (room temperature)
  • 34 cups Powdered sugar (estimate needed for buttercream, typically 34 cups)
  • 1 tsp Pure vanilla extract (estimate common for buttercream)
  • 23 tbsp Heavy cream or milk (estimate to achieve creamy consistency)

Instructions

  1. Prepare the cookie dough: In a large bowl, cream together the 1 cup of room temperature unsalted butter, brown sugar, white sugar, vanilla extract, and molasses until light and fluffy. Beat in the eggs one at a time until fully incorporated.
  2. Mix dry ingredients: In a separate bowl, whisk together all-purpose flour, baking soda, salt, ground cinnamon, pumpkin pie spice, and old fashioned oats.
  3. Combine ingredients: Gradually add the dry ingredients to the wet mixture, stirring until just combined to form the oatmeal cookie dough.
  4. Chill the dough: Cover the dough and chill in the refrigerator for at least 30 minutes to firm up for easier handling and better cookie shape retention.
  5. Preheat oven and prepare baking sheets: Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper or silicone baking mats.
  6. Scoop and bake cookies: Form dough into 1 1/2 tablespoon-sized balls and place them about 2 inches apart on the baking sheets. Flatten slightly if desired. Bake for 10-12 minutes or until edges are lightly golden but centers remain soft.
  7. Cool cookies: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
  8. Make the cream filling: In a mixing bowl, beat 1 cup softened unsalted butter until smooth and fluffy. Gradually add powdered sugar, about 1 cup at a time, beating well after each addition. Mix in vanilla extract and 2-3 tablespoons of heavy cream or milk, continuing to beat until light and creamy. Adjust powdered sugar or cream to achieve spreadable consistency.
  9. Assemble the oatmeal cream pies: Pair similar-sized cookies. Spread a generous dollop of the cream filling onto the flat side of one cookie, then gently sandwich with the other cookie. Press lightly to spread the filling evenly to the edges.
  10. Serve or store: Enjoy immediately, or store the assembled oatmeal cream pies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.

Notes

  • For best results, use room temperature butter and eggs for proper creaming and mixing.
  • Do not substitute blackstrap molasses; it can impart a bitter flavor.
  • Adjust the amount of powdered sugar in the filling depending on desired sweetness and consistency.
  • Cookies can be stored separately from filling for up to 3 days to maintain freshness before assembling.
  • Feel free to add a pinch of ground nutmeg or a dash of cloves to the cookie dough for extra warmth.
