Step‑by‑Step Instructions for Oatmeal Cream Pies
Step 1: Prepare the Dry Ingredients
In a large mixing bowl, whisk together 1 ¾ cups of all-purpose flour, 1 teaspoon of baking soda, 1 teaspoon of salt, 1 teaspoon of ground cinnamon, ½ teaspoon of pumpkin pie spice (or nutmeg), and 3 cups of old fashioned oats. This combination creates the base for your flavorful Oatmeal Cream Pies. Set the mixture aside while you work on the wet ingredients.
Step 2: Cream the Butters and Sugars
Using a stand mixer fitted with a paddle attachment, beat together 1 cup of unsalted butter, 1 cup of packed brown sugar, and ½ cup of white granulated sugar on high speed for about 2 minutes. The mixture should become creamy and light in color, indicating that it's well combined and ready for the next ingredients.
Step 3: Add Wet Ingredients
With the mixer on medium speed, add in 1 teaspoon of pure vanilla extract, ½ tablespoon of molasses, and 2 large eggs (make sure they’re at room temperature). Mix until all the wet ingredients are fully incorporated, and the batter has a smooth consistency, filling your kitchen with inviting aromas.
Step 4: Combine Dry and Wet Mixtures
Gradually add the reserved dry ingredient mixture to the wet ingredients in the mixer. Mix on low speed until just combined – do not overmix. The dough should be thick and hearty, perfect for forming the cookies that will make up your Oatmeal Cream Pies.
Step 5: Chill the Dough
Cover the mixing bowl with plastic wrap and chill the cookie dough in the refrigerator for 15 minutes. Meanwhile, preheat your oven to 350°F. Once ready, line two baking sheets with parchment paper to prepare for baking your delightful cookie sandwiches.
Step 6: Scoop the Dough
Using a cookie scoop or a tablespoon, scoop about 36 equal portions of the chilled dough onto the lined baking sheets. Place 12 cookies per baking sheet, leaving space between each scoop to allow for spreading. Return any remaining dough to the fridge to keep it firm while baking the first batch.
Step 7: Bake the Cookies
Bake the cookies in the preheated oven for 8 to 9 minutes, until they are just set and lightly golden. The edges should look firm, while the centers might still appear soft. After baking, allow the cookies to cool on the baking sheet for 4 minutes before transferring them to a wire rack to cool completely.
Step 8: Make the 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 and fluffy. This will serve as the delicious filling for your Oatmeal Cream Pies, giving them that signature texture and sweetness.
Step 9: Combine the Frosting Ingredients
Next, add 1 cup of sifted powdered sugar, 1 teaspoon of pure vanilla extract, and ¼ teaspoon of salt to the fluffy mixture. Blend on low speed until combined, then increase to high speed for another 4 minutes until the frosting is airy and spreadable, ready for assembly.
Step 10: Assemble the Pies
Once the cookies are completely cool, pipe or carefully spread a generous amount of marshmallow frosting onto the flat side of one cookie. Place a second cookie on top, flat side down, and gently press them together to create the sandwich. Repeat this process until all cookies are filled.
Step 11: Chill the Assembled Pies
After assembling your Oatmeal Cream Pies, place them in the freezer for at least 10 minutes. This helps the frosting set and makes the cookies easier to handle. If you're prepping ahead of time, store any leftover pies in the refrigerator to keep them fresh.
Step 12: Serve and Enjoy
Once chilled, your homemade Oatmeal Cream Pies are ready to serve! These delightful treats are perfect for sharing with family and friends, enhancing their appeal with a cup of coffee or tea.
How to Store and Freeze Oatmeal Cream Pies
Room Temperature: Store Oatmeal Cream Pies in an airtight container at room temperature for up to 3 days. This keeps them soft and fresh, perfect for daily treats.
Fridge: Keep them in the refrigerator for longer freshness, ideally up to a week. Just ensure they’re sealed tightly to prevent them from drying out.
Freezer: For longer storage, freeze Oatmeal Cream Pies in a single layer in an airtight container for up to 3 months. This maintains their delightful texture and flavor.
Reheating: To enjoy them warm, simply microwave the pies for 10-15 seconds. The marshmallow filling gets nice and gooey, making them even more delicious!
Make Ahead Options
These Oatmeal Cream Pies are perfect for busy home cooks looking to save time! You can prepare the cookie dough up to 24 hours in advance by chilling it in the refrigerator. Simply scoop the dough onto baking sheets and cover them with plastic wrap until you're ready to bake. The cookies themselves can be made and stored (in an airtight container) for up to 3 days before assembling. When it's time to enjoy, whip up the frosting and fill the cookies; this way, they're just as delightful and fresh-tasting as if you prepared them that day. For the best texture, chill the assembled pies for at least 10 minutes before serving!

Expert Tips for Oatmeal Cream Pies
-
Chill the Dough: Always chill your cookie dough for 15 minutes. This helps maintain the cookies’ texture and prevents them from spreading too much while baking.
-
Don’t Overmix: When combining the wet and dry ingredients, mix until just incorporated. Overmixing can lead to tough cookies rather than the soft, chewy Oatmeal Cream Pies you desire.
-
Perfect Baking Time: Bake the cookies for 8–9 minutes until just set. They will continue to firm up while they cool, so take them out of the oven while they still look slightly underbaked.
-
Room Temperature Ingredients: Ensure your butter and eggs are at room temperature for better incorporation and fluffiness, leading to a more tender cookie.
-
Customize the Spice: Feel free to adjust the spices! If you love cinnamon or nutmeg, increase the amounts for a more pronounced flavor throughout your Oatmeal Cream Pies.
Oatmeal Cream Pies Recipe FAQs
What is the best way to select ripe ingredients for my Oatmeal Cream Pies?
Absolutely! For the best flavor, choose unsalted butter that is soft but not melted—this helps create a creamy texture. For eggs, make sure they are at room temperature for optimal blending. When it comes to sugars, use brown sugar that is packed for moisture, and if you're using spices like cinnamon or nutmeg, check their freshness as well.
How should I store my Oatmeal Cream Pies to keep them fresh?
The more the merrier! Store your Oatmeal Cream Pies in an airtight container at room temperature for up to 3 days. This keeps them delightfully soft and chewy. If you want to extend their shelf life, refrigerate them for up to a week. Just be sure they're sealed tightly to prevent them from drying out.
Can I freeze Oatmeal Cream Pies? If yes, how?
Absolutely! To freeze your Oatmeal Cream Pies, place them in a single layer in an airtight container and store them in the freezer for up to 3 months. To prevent sticking, you might use parchment paper between layers. When you're ready to enjoy them, thaw them in the refrigerator overnight or microwave them for 10-15 seconds until warm and gooey.
What should I do if my cookie dough appears too dry?
Very good question! If your dough seems too dry, it may be that the flour was overmeasured or not enough moisture was added. Try adding a tablespoon of milk to the dough to achieve a softer texture. Additionally, make sure you're not overmixing your wet and dry ingredients. Mix until just combined for that perfect chewy cookie bite!
Can I make Oatmeal Cream Pies with gluten-free flour?
Certainly! Many people love to customize their recipes for dietary needs. You can substitute all-purpose flour with a gluten-free blend, but I recommend adding a bit of xanthan gum (about ½ teaspoon) to mimic the texture of traditional flour. Keep in mind that results may vary slightly, but they should still taste delicious!
