How to Make Oatmeal Cream Pies
-
Preheat the Oven:
Start by preheating your oven to 350°F, positioning racks in the upper and lower thirds. This ensures even baking. Then, line two baking sheets with parchment paper for easy cleanup. -
Pulse the Oats:
In a food processor, pulse the oats until they break down into small pieces, avoiding a powdery texture. Next, add the flour, cinnamon, baking soda, and salt, pulsing a few more times to combine everything evenly. -
Cream the Mixture:
Using a hand mixer or a stand mixer fitted with the paddle attachment, beat the butter, brown sugar, and granulated sugar together until creamy. Add the eggs, molasses, and vanilla, and continue mixing until combined. Scrape the sides and bottom of the bowl as needed. -
Combine the Ingredients:
Introduce the dry ingredients to the wet mixture and beat until fully integrated. Allow the dough to rest at room temperature for 5 minutes—it’ll firm up just a bit! -
Shape the Cookies:
Scoop the dough into 1½ tablespoon balls and place them a couple of inches apart on the prepared baking sheets. Bake for 9-11 minutes, or until the edges begin to set while the centers remain slightly underdone. -
Cool and Frost:
Once baked, transfer the cookies to wire racks to cool completely. For the filling, beat the softened butter until smooth. Add the marshmallow crème and mix until combined. Gradually include the powdered sugar, followed by the vanilla and a pinch of salt. -
Assemble the Pies:
Fill a piping bag fitted with a large round tip, and squeeze some frosting onto the underside of one cookie. Top it with another cookie, creating a delightful sandwich. Repeat until all cookies are paired.
Optional: Dust the finished oatmeal cream pies with a sprinkle of powdered sugar for a charming finish!

Oatmeal Cream Pies Recipe FAQs
How do I choose the right oats for my Oatmeal Cream Pies?
Absolutely! You can use either quick oats or old-fashioned oats. Quick oats will give you a softer texture, while old-fashioned oats add more chewiness for a heartier cookie. Both options are delicious, so it’s really a matter of personal preference!
How should I store my Oatmeal Cream Pies after baking?
For optimal freshness, store your Oatmeal Cream Pies in an airtight container at room temperature for up to 3 days. If there are leftovers (which is rare!), you can refrigerate them in an airtight container for up to a week. They’ll be soft and ready to enjoy!
Can I freeze Oatmeal Cream Pies? How?
Yes! You can absolutely freeze your Oatmeal Cream Pies to enjoy later. Simply place the assembled cookies in a single layer on a baking sheet and freeze them for about an hour. Once they’re firm, transfer them to a freezer bag. They’ll keep well for up to 3 months. To enjoy, let them thaw in the fridge or at room temperature.
What if my cookies spread too much during baking?
Very! If your Oatmeal Cream Pies spread too much, it might be due to the butter being too soft or warm when mixed. Ensure your butter is softened but cool to the touch. Also, try chilling the dough for 30 minutes before scooping and baking to help maintain shape.
Are these cookies suitable for people with allergies?
When considering allergies, keep in mind that the recipe uses gluten (all-purpose flour) and dairy (butter). For gluten-free options, substitute with a gluten-free all-purpose flour blend. If you have egg allergies, consider using flax eggs as a binding substitute—1 tablespoon of ground flax mixed with 2.5 tablespoons of water equals one egg.
How long does it take for the cookies to cool before frosting?
After baking, it’s best to let your cookies cool on the wire racks for at least 30 minutes. This ensures that they are completely set before you frost them, preventing the filling from making them gooey and messy!
