Instructions
Oatmeal Cookies
- Preheat the oven to 350ยฐF (180ยฐC or 170ยฐC fan-forced). Line cookie sheets with silicone baking mats or baking paper.
- In a large bowl, beat the butter, brown sugar, and granulated sugar together until fluffy.
- Mix in the molasses, vanilla extract, and eggs until creamy.
- Turn off the mixer and add the flour, cinnamon, baking soda, and salt. Stir a few times by hand, then mix on low speed until incorporated.
- Stir in the oats.
- Form the dough into balls about 1 to 1 1/2 tablespoons in size. Place them 2 inches apart on the prepared cookie sheets. The recipe typically makes about 32โ34 cookies, enough for 16โ17 sandwiches.
- Bake one sheet at a time in the middle of the preheated oven for about 9โ11 minutes, or until the tops look set.
- Cool the cookies on the baking sheet for at least 10 minutes before transferring them to a wire rack to cool completely.
Cream Filling
- In a large bowl, beat the butter until fluffy.
- Cut the cream cheese into 3โ4 pieces and beat it into the butter.
- Add 1 1/2 cups powdered sugar, vanilla, and salt. Start mixing on low speed, then gradually increase to medium until combined.
- Beat in the remaining powdered sugar about 1/2 cup at a time until the desired sweetness is reached. If the frosting is too thick, beat in 1 tablespoon of cream.
Assemble the Cookies
- Spread about 1 to 1 1/2 tablespoons of frosting onto the bottom of one completely cooled cookie.
- Place a second cookie on top, with its bottom facing down, to make a sandwich. Repeat with the remaining cookies and filling.
Notes
- Smaller batch: Divide the recipe in half to make a smaller batch.
- Molasses: Molasses adds the classic oatmeal cream pie flavor. Honey can be substituted if needed.
- Flour: Measure carefully to help prevent dry cookies. Whisk the flour, spoon it into a dry measuring cup, and level the top, or use a kitchen scale.
- Oats: Quick oats are preferred, but rolled oats can also be used.
- Cream cheese: Replace the cream cheese with additional butter if preferred.
- Make ahead: Bake the cookies 1โ2 days ahead, cool completely, and store at room temperature in an airtight container. Cookies can also be frozen for up to 2 months in an airtight container. Thaw in the refrigerator and frost when ready to serve.
- Storage: Store assembled cream pies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days.
- Nutrition: Nutrition information is an estimate based on one cookie and the recipe yielding 16 equal-sized servings with all the frosting used.
