How to Make Oatmeal Cream Pies
Step 1: Prepare the Dry Ingredients
In a large bowl, whisk together the flour, baking soda, salt, cinnamon, pumpkin pie spice, and oats. Set aside.
Step 2: Cream the Butter and Sugars
In a mixer, beat the butter, brown sugar, and granulated sugar together on high speed for 2 minutes until creamy.
Step 3: Incorporate Wet Ingredients
Add the vanilla, molasses, and eggs. Mix on medium speed until fully combined.
Step 4: Combine Dry Ingredients
Gradually add in the dry ingredients from Step 1. Mix on low speed until just incorporated.
Step 5: Chill the Dough
Chill the dough in the fridge for 15 minutes while you preheat the oven to 350°F. Line two baking sheets with parchment paper.
Step 6: Scoop Cookies
Scoop dough using a cookie scoop to form 36 cookies (about 3 dozen). Place 12 cookies per baking sheet and return remaining dough to the fridge between batches.

How to Perfect Oatmeal Cream Pies
To ensure your homemade Oatmeal Cream Pies turn out perfectly every time, consider these helpful tips:
-
Chill the dough: Allowing the cookie dough to chill ensures thicker cookies that hold their shape better during baking.
-
Use room temperature ingredients: Using room temperature butter and eggs helps create a smooth batter, leading to evenly baked cookies.
-
Don’t overmix: Once you combine the dry ingredients with wet ones, mix just until incorporated to maintain cookie tenderness.
-
Scoop consistently: Use a cookie scoop for uniform cookies, ensuring even baking and consistent sizes when making sandwiches.
Best Side Dishes for Oatmeal Cream Pies
Oatmeal Cream Pies pair wonderfully with various side dishes that complement their flavors. Here are some excellent choices:
-
Fresh Fruit Salad: A light and refreshing option that adds brightness and balances the sweetness of the pies.
-
Chocolate Milkshake: Indulge in this creamy treat for a rich pairing that kids will love alongside their cookies.
-
Yogurt Parfait: Layer yogurt with granola and berries for a nutritious side that contrasts nicely with the sugary pies.
-
Cheese Platter: A selection of cheeses can provide savory notes that contrast beautifully with the sweetness of your Oatmeal Cream Pies.
-
Nut Butter Dip: Serve apple slices or pretzels with nut butter for dipping, providing crunchy textures next to soft sandwiches.
-
Mini Muffins: Offer mini muffins in various flavors like banana or blueberry as additional sweet bites alongside your cookies.
Common Mistakes to Avoid
Avoiding common pitfalls can elevate your Oatmeal Cream Pies from good to great. Here are some mistakes to watch out for:
-
Incorrect flour measurement: Using too much flour can lead to dry cookies. Always spoon and level the flour or use a kitchen scale for accurate measuring.
-
Skipping chilling time: Not chilling the dough can result in cookies that spread too much while baking. Ensure you chill the dough for at least 15 minutes before baking.
-
Overmixing the dough: Mixing too long can make cookies tough. Mix until just combined to keep them soft and chewy.
-
Not letting cookies cool properly: Transferring cookies too quickly can cause them to break. Let them cool on the baking sheet for a few minutes before moving them.
-
Using cold ingredients: Cold butter and eggs can affect texture. Bring these ingredients to room temperature before starting your recipe.
