Ingredients Section
To make these delightful Pumpkin Spice Oatmeal Cream Pies, you’ll need the following ingredients:
For the Cookies:
- 1 1/2 cups all-purpose flour
- 2 cups old fashioned oats
- 1 tablespoon pumpkin pie spice
- 1/2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon kosher salt
- 1/4 teaspoon nutmeg
- 1/2 cup unsalted butter, room temperature
- 1 cup light brown sugar, packed
- 2 large eggs, room temperature
- 1 tablespoon molasses
- 1 teaspoon vanilla extract
For the Filling:
- 3/4 cup unsalted butter, softened
- 1 jar marshmallow fluff or marshmallow creme (about 7 oz)
- 3 cups confectioners’ sugar
Ingredient Notes:
- Substitutions: If you’re out of molasses, honey or agave syrup can work, although the flavor may vary slightly.
- Quality Matters: Aim for high-quality vanilla extract and unsalted butter for the best flavor.
- Room Temperature Ingredients: Make sure your butter and eggs are at room temperature for a smoother batter.

Step-by-Step Instructions
Preheat the Oven: Start by preheating your oven to 400 degrees F (200 degrees C). This ensures that your cookies bake evenly and come out soft and chewy.
Prepare the Baking Sheet: Line a baking sheet with parchment paper; this prevents sticking and makes cleanup a breeze.
Mix Dry Ingredients: In a large mixing bowl, whisk together the flour, oats, pumpkin pie spice, baking powder, baking soda, salt, and nutmeg until evenly combined. The wonderful fragrance of the spice blend will fill your kitchen like a warm hug!
Cream Butter and Sugar: In a stand mixer, beat the room-temperature butter and brown sugar together on low speed until smooth and creamy, about 2-3 minutes. You want it to look light and fluffy.
Add in Wet Ingredients: Add the eggs, molasses, and vanilla to the butter-sugar mixture. Beat until everything is fully incorporated.
Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Avoid overmixing; you want to keep that tender texture.
Scoop and Shape: Using a cookie scoop or two spoons, drop scoops of dough onto the prepared baking sheet, leaving a bit of space between each cookie. Lightly flatten the tops with your fingers.
Bake: Bake in the preheated oven for about 7-8 minutes, or until the edges are set but the centers still look a bit doughy. They’ll firm up as they cool!
Cool Down: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Make the Filling: While the cookies cool, prepare your filling. In a mixing bowl, beat the softened butter and marshmallow fluff together until smooth. Gradually add the confectioners’ sugar until stiff and creamy.
Assemble: Once the cookies are completely cool, spread a generous dollop of the marshmallow filling onto the flat side of one cookie and top with a second cookie, flat side down. Press gently to spread the filling for an even layer.
Serve and Enjoy!: Your delicious Pumpkin Spice Oatmeal Cream Pies are ready to enjoy! Store extras in an airtight container.
Chef’s Tip: Make sure not to overbake the cookies! They should look slightly underbaked in the center when you take them out, as they will continue to cook on the baking sheet.
Common Mistakes to Avoid: Ensure your butter is not melted, as this will lead to flat cookies. Room temperature means softened but still solid.
Expert Tips & Tricks
Use Fresh Spices: Spice freshness can significantly impact flavor, so check the expiration date of your spices to ensure a vibrant taste.
Testing for Doneness: Cookies are done baking when the edges are lightly browned, and the centers appear slightly underbaked. Remember, they will firm up while cooling!
Storage Recommendations: Store these cookies in an airtight container at room temperature for up to 4 days. They freeze well too! Just ensure they are well-wrapped.
Make-Ahead Instructions: You can prepare the cookie dough and freeze it for up to 3 months. Just thaw completely before baking!
Troubleshooting: If your cream filling is too soft, add a bit more confectioners’ sugar until it firms up nicely but remains spreadable.
