Ingredients
For the Oatmeal Cookies
- 1 cup (225g / 2 sticks) unsalted butter, softened
- 1 cup (200g / 0.44 lb) brown sugar, packed
- ½ cup (100g / 0.22 lb) granulated sugar
- 2 large eggs
- 1 tbsp molasses (optional, but adds depth of flavor)
- 1 tsp vanilla extract
- 1 ½ cups (190g / 0.42 lb) all-purpose flour
- 1 tsp baking soda
- ½ tsp salt
- 1 ½ tsp ground cinnamon
- 3 cups (270g / 0.6 lb) old-fashioned rolled oats
For the Marshmallow Cream Filling
- ½ cup (115g / 1 stick) unsalted butter, softened
- 1 cup (120g / 0.26 lb) powdered sugar
- 1 tsp vanilla extract
- 1 jar (7 oz / 198g) marshmallow fluff
- 1-2 tbsp heavy cream (optional, for thinning the filling)
Directions
Step 1: Make the Oatmeal Cookies
- Preheat the Oven:
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats. - Cream the Butter and Sugars:
In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together until light and fluffy, about 2-3 minutes. - Add the Eggs, Vanilla, and Molasses:
Beat in the eggs one at a time, followed by the vanilla extract and molasses (if using), until well combined. - Mix the Dry Ingredients:
In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon. Gradually add the dry ingredients to the wet ingredients, mixing until combined. - Add the Oats:
Stir in the old-fashioned oats until evenly distributed throughout the dough. - Scoop the Dough:
Use a cookie scoop or tablespoon to drop small balls of dough onto the prepared baking sheets, leaving about 2 inches of space between each cookie. - Bake:
Bake the cookies for 10-12 minutes, or until the edges are lightly golden. The centers will still be soft but will firm up as they cool. - Cool:
Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
Step 2: Make the Marshmallow Cream Filling
- Cream the Butter:
In a medium bowl, beat the softened butter until smooth and creamy. - Add the Powdered Sugar and Vanilla:
Gradually mix in the powdered sugar and vanilla extract until fully combined. - Mix in the Marshmallow Fluff:
Gently fold in the marshmallow fluff until the mixture is light and fluffy. - Adjust the Consistency:
If the filling is too thick, add 1-2 tablespoons of heavy cream to thin it out to your desired consistency.
Step 3: Assemble the Oatmeal Cream Pies
- Pair the Cookies:
Match up the cookies in pairs based on similar size and shape. - Spread the Filling:
Spread or pipe a generous layer of the marshmallow cream filling onto the flat side of one cookie, then sandwich it with the other cookie. - Chill (Optional):
For easier handling, you can refrigerate the assembled cream pies for 15-20 minutes to help the filling set before serving.
Step 4: Serve and Enjoy
Enjoy these delicious homemade oatmeal cream pies with a cold glass of milk, or pack them up for lunchbox treats, parties, or a nostalgic dessert!
Notes
- Molasses: The molasses is optional but adds a rich, caramel-like flavor to the cookies. You can substitute with honey or maple syrup if desired.
- Storage Tips: Store leftover oatmeal cream pies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
- Freezer-Friendly: These oatmeal cream pies can be frozen for up to 2 months. Simply wrap each pie individually in plastic wrap and place them in a freezer-safe container. Thaw in the fridge or at room temperature before serving.
- Make Ahead: The cookies and filling can both be made ahead of time. Store the cookies in an airtight container and the filling in the fridge for up to 3 days. Assemble when ready to serve.
Frequently Asked Questions
Can I use quick oats instead of old-fashioned oats?
Yes, but old-fashioned oats provide more texture. Quick oats will give you a softer cookie, which still works great for these cream pies.
Can I make these gluten-free?
Yes! Substitute the all-purpose flour with a 1:1 gluten-free flour blend and make sure your oats are certified gluten-free.
How do I keep the filling from oozing out?
Make sure the cookies are completely cooled before adding the filling. You can also refrigerate the assembled pies for a bit to help set the filling.
Can I use a different filling?
Yes! You can use a simple buttercream or cream cheese frosting for a different take, but the marshmallow filling is what gives it that classic taste.
How do I keep the cookies soft?
To keep the cookies soft, store them in an airtight container. Adding a slice of bread to the container can help retain moisture and keep the cookies soft.
Tips and Notes
- My Tip: For an extra special touch, sprinkle a little sea salt on top of the cookies before baking to balance the sweetness of the filling.
- Pro Trick: Use a piping bag to add the marshmallow cream filling for a cleaner, more uniform look.
- Serving Suggestion: Serve these oatmeal cream pies slightly chilled for a firmer texture, or enjoy them at room temperature for a softer, gooier treat.
Variations
- Peanut Butter Oatmeal Cream Pies: Add ½ cup of peanut butter to the cookie dough for a nutty twist, or mix peanut butter into the marshmallow filling.
- Chocolate-Dipped Oatmeal Cream Pies: Dip half of each assembled cream pie in melted chocolate for an extra indulgent treat.
- Pumpkin Spice Oatmeal Cream Pies: Add 1 teaspoon of pumpkin spice to the cookie dough for a fall-inspired flavor.
- Coconut Oatmeal Cream Pies: Stir in ½ cup of shredded coconut to the cookie dough for a tropical take on the classic.
- Healthier Oatmeal Cream Pies: Use coconut oil instead of butter, and substitute half of the flour with whole wheat flour for a healthier version.
