Homemade Oatmeal Cream Pies Recipe

There’s something undeniably nostalgic about Oatmeal Cream Pies. For many of us, they bring back memories of school lunches and sweet after-dinner treats. But did you know you can make an even better version right at home? These Homemade Oatmeal Cream Pies are soft, chewy, and loaded with warm spices. Sandwiched with a rich marshmallow cream filling, they’re the ultimate upgrade from the store-bought version.

Ingredients

For the Oatmeal Cookies:

• 1 cup unsalted butter, softened
• 3/4 cup brown sugar
• 1/2 cup granulated sugar
• 2 large eggs
• 1 tablespoon molasses
• 1 teaspoon vanilla extract
• 1 1/2 cups all-purpose flour
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt
• 1 teaspoon cinnamon
• 1/4 teaspoon ground nutmeg (optional)
• 2 cups old-fashioned rolled oats

For the Cream Filling:

• 1/2 cup unsalted butter, softened
• 1 cup powdered sugar
• 1 jar (7 oz) marshmallow fluff
• 1 teaspoon vanilla extract

Instructions

1. Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper.
2. Make the cookie dough: In a large bowl, cream the butter and sugars together until light and fluffy. Add eggs one at a time, then mix in molasses and vanilla.
3. In a separate bowl, whisk together flour, baking soda, salt, cinnamon, and nutmeg. Gradually add to the wet mixture, then fold in the oats.
4. Drop tablespoon-sized scoops of dough onto the prepared baking sheets, spacing them 2 inches apart. Flatten slightly with the back of a spoon.
5. Bake for 9–11 minutes, or until the edges are lightly golden. Let cool completely on a wire rack.
6. Prepare the filling: In a bowl, beat the butter until creamy. Add powdered sugar, marshmallow fluff, and vanilla, beating until smooth and fluffy.
7. Assemble: Spread or pipe the cream filling on the flat side of one cookie, then sandwich with another. Repeat for all.

To Make It Gluten-Free:

You can easily adapt this recipe by using:

1. Gluten-Free All-Purpose Flour Blend – Use a 1:1 gluten-free baking flour (such as Bob’s Red Mill or King Arthur’s).
2. Certified Gluten-Free Rolled Oats – Make sure the oats are labeled gluten-free to avoid cross-contamination.

These Homemade Oatmeal Cream Pies are soft, gooey, and full of nostalgic flavor. They store well in an airtight container, but let’s be real—they probably won’t last that long. Perfect for holidays, lunchboxes, or whenever you need a little sweet pick-me-up!
