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, and 3 cups of old-fashioned oats until well combined. This blend of dry ingredients will provide a hearty base for your Oatmeal Cream Pies. Set the mixture aside while you work on the wet ingredients.

Step 2: Cream the Butter and Sugars
In your stand mixer, beat together 1 cup of unsalted butter, 1 cup of brown sugar, and ½ cup of white granulated sugar on high speed for about 2 minutes. Look for a creamy consistency that’s light in color. This step is crucial as it aerates the mixture, which contributes to the soft and chewy texture of the cookies.

Step 3: Add the Wet Ingredients
Next, add in 1 teaspoon of pure vanilla extract, ½ tablespoon of molasses, and 2 large eggs that are at room temperature. Mix these ingredients on medium speed until they are fully combined, ensuring everything is well incorporated and smooth. The rich flavors will start to infuse, setting a delightful foundation for your Oatmeal Cream Pies.

Step 4: Combine Wet and Dry Ingredients
Gradually incorporate the dry ingredients into the wet mixture by mixing on low speed until just combined. Be careful not to overmix, as this can make the cookies tough. You want to see a thick, cookie dough consistency that will form the perfect chewy layer for your Oatmeal Cream Pies.

Step 5: Chill the Dough
Chill the cookie dough in the refrigerator for 15 minutes. While the dough is cooling, preheat your oven to 350°F and line two baking sheets with parchment paper. Chilling the dough helps to firm it up, which prevents the cookies from spreading too much during baking, ensuring they remain thick and chewy.

Step 6: Scoop the Cookies
Using a cookie scoop, portion out the chilled dough to form about 36 cookies. Place 12 cookies per baking sheet, ensuring ample space between each one. Keep any remaining dough in the refrigerator between batches. This careful spacing allows the cookies room to spread and bake evenly, achieving that desirable shape.

Step 7: Bake the Cookies
Bake the cookies in the preheated oven for 8–9 minutes or until they are just set but still soft in the center. You’ll know they’re ready when the edges are lightly golden. 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 airy texture is vital for making the frosting delightful and spreadable, perfect for filling your Oatmeal Cream Pies.

Step 9: Incorporate Remaining Frosting Ingredients
Add in 1 cup of sifted powdered sugar, 1 teaspoon of pure vanilla extract, and ¼ teaspoon of salt to the fluffy mixture. Mix on low speed until combined, then increase to high speed and beat for another 4 minutes. You’re aiming for a light and spreadable frosting that perfectly complements the cookies.

Step 10: Assemble the Pies
Pipe or spread a generous amount of the marshmallow frosting onto the flat side of one cooled cookie, creating a luscious layer. Gently sandwich it with another cookie, pressing together lightly to ensure the filling oozes out slightly for that scrumptious look of your Oatmeal Cream Pies.

Step 11: Chill the Assembled Pies
Place the assembled cookie sandwiches in the freezer for at least 10 minutes before serving. This helps the filling set slightly, making each bite perfectly balanced. If you have any leftovers, store them in the refrigerator for longer-lasting deliciousness in your Oatmeal Cream Pies.

Expert Tips for Oatmeal Cream Pies

Chill the Dough: Make sure to chill your cookie dough for at least 15 minutes. This helps maintain a chewy texture and prevents excessive spreading during baking.

Don't Overmix: When combining wet and dry ingredients, mix until just incorporated. Overmixing can lead to tough cookies, which you definitely want to avoid!

Even Baking: Always use parchment paper on your baking sheets; it helps cookies bake evenly and prevents sticking, ensuring your Oatmeal Cream Pies come out perfectly.

Use Room Temperature Ingredients: For the best consistencies, ensure your butter and eggs are at room temperature. This contributes to a fluffier texture in both cookies and frosting.

Texture Check: Bake until cookies are just set and slightly soft in the center. They’ll continue to firm up as they cool, giving you that soft, chewy goodness!

These tips are sure to elevate your Oatmeal Cream Pies to the next level of deliciousness!

Oatmeal Cream Pies Recipe FAQs

How do I choose the right oats for my Oatmeal Cream Pies?
Absolutely! For the best texture in your Oatmeal Cream Pies, always opt for old-fashioned oats. They provide that hearty chewiness that instant oats lack. Instant oats can make the cookies too mushy, so stick with the old-fashioned variety for the perfect balance!

What’s the best way to store my Oatmeal Cream Pies?
To keep your Oatmeal Cream Pies fresh and delicious, store them in an airtight container in the refrigerator. They’ll maintain their chewy texture for up to 5 days. If you don’t think you’ll finish them within that timeframe, consider the freezer!

Can I freeze Oatmeal Cream Pies?
Yes! Freezing is a great option for storing Oatmeal Cream Pies. Wrap each pie individually in plastic wrap to prevent freezer burn, then place them in a freezer-safe bag. They will stay delicious for up to 3 months! When you’re ready to enjoy them, simply thaw in the fridge overnight or let them sit at room temperature for about 30 minutes.

What should I do if my Oatmeal Cream Pies spread too much while baking?
Very! If your cookies spread too much, it could be due to the dough being too warm or not enough chilling time. Always remember to chill your dough for at least 15 minutes before baking. Additionally, try checking your oven temperature with an oven thermometer; sometimes, an oven can be a bit off.

Are Oatmeal Cream Pies suitable for someone with allergies?
It largely depends on individual allergies. If you or someone you’re baking for has allergies to gluten, dairy, or eggs, consider using gluten-free oats, dairy-free butter substitutes, and egg replacements. Always check the labels on your ingredients to ensure they are safe for your specific dietary needs!

Can I use other fillings instead of marshmallow fluff?
Definitely! While the marshmallow filling is traditional, you can experiment with other fillings such as cream cheese frosting or chocolate ganache to create a unique twist on Oatmeal Cream Pies. This versatility allows you to customize your pies to match your taste or special occasions.
