Ingredients
For the Oatmeal Cookies
- 1 cup unsalted butter, softened
- 3/4 cup firmly packed light brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla bean paste
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- 1/2 teaspoon salt
- 3 cups quick or old fashioned oats
For the Cream Filling
- 3/4 cup unsalted butter, softened
- 2 1/2 cups confectioners’ sugar, sifted
- 1 teaspoon vanilla bean paste
- 1 tablespoon milk or half and half
Instructions
- Preheat and prepare baking sheets: Preheat your oven to 350°F (175°C). Line cookie sheets with parchment paper to prevent sticking and ensure even baking.
- Cream butter and sugars: In a stand mixer fitted with the paddle attachment, or a large bowl with an electric mixer, cream together the softened butter, light brown sugar, and granulated sugar until the mixture is light and fluffy, about 3 minutes.
- Add eggs and vanilla: Beat in the eggs one at a time along with the vanilla bean paste until evenly combined.
- Mix dry ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and salt.
- Combine wet and dry ingredients: Gradually add the flour mixture to the wet ingredients, mixing just until combined. Stir in the oats until fully incorporated without overmixing.
- Portion and bake cookies: For large cookies, use a 3-tablespoon cookie scoop to drop dough onto the prepared sheets; bake for 13-15 minutes or until golden brown. For smaller cookies, use a 1.5-tablespoon scoop and bake for 10-12 minutes.
- Cool cookies: Let cookies sit on the baking sheet for about 5 minutes after baking, then transfer to a wire rack to cool completely before assembling.
- Prepare the cream filling: In a clean bowl, beat softened butter on medium-high speed for about 5 minutes until lightened in color and fluffy.
- Add powdered sugar and liquids: Reduce mixer speed to low, gradually add sifted confectioners’ sugar until fully blended. Mix in vanilla bean paste and milk or half-and-half until combined.
- Beat filling to desired consistency: Increase speed to medium-high and beat for an additional 3-5 minutes. Add more milk 1 teaspoon at a time if needed to reach the perfect creamy, spreadable texture.
- Assemble the pies: Spread or pipe a generous amount of cream filling onto the flat side of half the cooled cookies. Top with remaining cookies to form sandwiches, pressing gently to distribute the filling evenly.
Notes
- For firmer cream filling, chill for 15-20 minutes before assembling.
- Use parchment paper or silicone baking mats to prevent sticking and ease cleanup.
- Store assembled oatmeal cream pies in an airtight container at room temperature for up to 3 days or refrigerate for up to 1 week.
- The recipe can be doubled easily to make more servings.
- Substitute old fashioned oats with quick oats, but texture will be slightly different.
