Step‑by‑Step Instructions for Oatmeal Cream Pies
Step 1: Prepare the Dry Ingredients
In a large mixing bowl, whisk together 1 ¾ cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon salt, 1 teaspoon ground cinnamon, ½ teaspoon pumpkin pie spice, and 3 cups old-fashioned oats until evenly combined. The dry mixture should appear uniform, with no lumps. Set aside this bowl as we focus on creating the cookie dough.
Step 2: Cream the Butter and Sugars
In a stand mixer fitted with a paddle attachment, beat 1 cup of unsalted butter, 1 cup of packed brown sugar, and ½ cup of white granulated sugar on high speed for 2 minutes until the mixture is creamy and light. You’ll notice a fluffy texture and a delightful sweetness filling the air, making this your base for delicious Oatmeal Cream Pies.
Step 3: Add the Wet Ingredients
Next, add 1 teaspoon of pure vanilla extract, ½ tablespoon of molasses, and 2 large room temperature eggs to the butter and sugar mixture. Mix on medium speed until everything is well combined and smooth, approximately 1-2 minutes. This step will enhance the richness of your cookie dough, creating that much-loved flavor profile.
Step 4: Combine the Dry and Wet Ingredients
Gradually sprinkle the dry ingredients from Step 1 into the mixing bowl, then mix on low speed until just incorporated. Aim for a dough that is thick but slightly sticky; be careful not to over-mix as this can affect the texture of your Oatmeal Cream Pies. Once combined, you’re almost ready to bake!
Step 5: Chill the Dough
Cover the mixing bowl with plastic wrap and chill the cookie dough in the fridge for 15 minutes while you preheat your oven to 350°F (175°C). During this time, line two baking sheets with parchment paper to prepare for baking. This chilling step helps solidify the butter, leading to thicker cookies.
Step 6: Scoop and Shape the Cookies
Using a cookie scoop, portion out the dough to form approximately 36 cookies (3 dozen). Place 12 cookie mounds on each baking sheet, leaving adequate space between them to allow for spreading. Be sure to return any remaining dough back to the fridge to keep it cool while you bake each batch.
Step 7: Bake the Cookies
Bake the cookies in the preheated oven for 8–9 minutes, or until they are just set and lightly golden around the edges. Keep an eye on them; they should look soft but not doughy in the center. Once baked, allow them to cool on the sheets for about 4 minutes before transferring to a wire rack to cool completely.
Step 8: Make the Marshmallow Frosting
In a clean mixing bowl, beat together 1 cup of unsalted butter and 7 oz of marshmallow fluff on high speed for about 3 minutes until the mixture is light, fluffy, and creamy. You want it to have a smooth consistency that’s easy to spread, setting the stage for the delightful filling of your Oatmeal Cream Pies.
Step 9: Add Sugar and Flavor
To the marshmallow frosting, add 1 cup of sifted powdered sugar, 1 teaspoon of pure vanilla extract, and ¼ teaspoon of salt. Mix on low speed until combined, then increase to high speed for another 4 minutes until the frosting is airy and perfectly spreadable. This frosting is what makes an Oatmeal Cream Pie truly special.
Step 10: Assemble the Cookies
Once your cookie halves are completely cool, pipe or spread a generous amount of marshmallow frosting onto the flat side of one cookie. Top it off with another cookie, flat side down, gently pressing them together to create a delightful sandwich. Repeat this process until all cookies are filled.
Step 11: Chill the Assembled Pies
To set the shape of your Oatmeal Cream Pies, place the sandwiches in the freezer for at least 10 minutes before serving. This chilling step allows the frosting to firm up slightly for easy handling. If you've made more than you can eat right away, store any extras in the refrigerator for a sweet treat later!

Expert Tips for Oatmeal Cream Pies
-
Room Temperature Ingredients: Ensure butter and eggs are at room temperature for a smoother dough that's easier to mix. This will enhance the overall texture of your Oatmeal Cream Pies.
-
Don’t Overmix: Mix the wet and dry ingredients just until combined to avoid tough cookies. Overmixing can lead to a denser texture which we want to avoid for a light, chewy experience.
-
Chill the Dough: Allowing the cookie dough to chill before baking is essential. This step helps prevent spreading, ensuring your Oatmeal Cream Pies hold their shape well!
-
Check Baking Time: Keep an eye on your cookies as they bake; you want them set but not overdone. Slightly underbaking will yield a softer texture, perfect for those chewy bites.
-
Customize Your Fillings: Feel free to add mix-ins like chocolate chips or nuts to the cookie dough for a fun twist. This personal touch will elevate your beloved Oatmeal Cream Pies!
How to Store and Freeze Oatmeal Cream Pies
Fridge: Store assembled Oatmeal Cream Pies in an airtight container for up to 5 days. This keeps them fresh and the marshmallow filling soft.
Freezer: For longer storage, freeze the unassembled cookies and frosting separately. Cookies can be frozen for up to 3 months, while the frosting will also keep well.
Reheating: To enjoy the cookies warm, microwave them on a low setting for 10-15 seconds. This revives their soft, chewy texture perfectly!
Thawing: When ready to eat the frozen cookies, let them thaw in the fridge overnight, then fill with frosting just before serving for the best taste and texture.

Oatmeal Cream Pies Recipe FAQs
What should I look for when selecting oats?
Absolutely! For this recipe, it's best to use old-fashioned oats, which provide that chewy texture you love. Look for oats that are whole and intact without any signs of moisture or spoilage. Oats that have an even color and no dark spots will ensure the best flavor and texture in your Oatmeal Cream Pies.
How should I store leftover Oatmeal Cream Pies?
To keep your Oatmeal Cream Pies fresh, simply store them in an airtight container in the refrigerator for up to 5 days. This method maintains the softness of the cookies and the fluffiness of the marshmallow frosting. If they're soggy, consider layering parchment paper between the pies to avoid moisture buildup.
Can I freeze Oatmeal Cream Pies?
Absolutely! To freeze your Oatmeal Cream Pies, I recommend separating the cookies and the marshmallow frosting. Place the unassembled cookies in a single layer on a baking sheet to freeze for about 2 hours until solid. Then, transfer them to a freezer bag, where they can be kept for up to 3 months. The frosting can also be frozen in a separate container. When you're ready to enjoy, simply thaw the cookies in the fridge overnight and assemble them fresh!
What if my cookie dough seems too sticky?
Very! If your dough is overly sticky, try chilling it longer. This helps to solidify the butter and allows for easier scooping. If the problem persists, you can gently work in a bit of extra flour, one tablespoon at a time, until it reaches a manageable consistency. Just be cautious not to add too much, as it could alter the texture of your Oatmeal Cream Pies.
Are Oatmeal Cream Pies suitable for people with allergies?
Keep in mind that Oatmeal Cream Pies contain common allergens such as gluten (in flour and oats), dairy (butter), and eggs. If you're making these for guests, it’s best to ask about any allergies beforehand. You can also explore substituting gluten-free flour and plant-based butter for a safer option for those with dietary restrictions!
