How to Make Oatmeal Cream Pies
Step 1: Make the Oatmeal Cookies
- In a large bowl, whisk together the flour, baking soda, salt, cinnamon, pumpkin pie spice, and oats. Set aside.

- Add the vanilla, molasses, and eggs to the mixture. Mix on medium speed until fully combined.
- Gradually add in the dry ingredients and mix on low speed until just incorporated.
- Chill the dough in the fridge for 15 minutes while preheating your oven to 350°F. Line two baking sheets with parchment paper.
- Using a cookie scoop, form 36 cookies (about 3 dozen). Place 12 cookies per baking sheet and return remaining dough to the fridge between batches.
- Bake for 8–9 minutes or until just set. Let cool on the baking sheet for 4 minutes before transferring to a wire rack to cool completely.
Step 2: Make the Marshmallow Cream Frosting

How to Perfect Oatmeal Cream Pies
Making perfect Oatmeal Cream Pies requires attention to detail and some helpful tips. Follow these suggestions to ensure your pies are delicious every time.
- Use room temperature ingredients – This helps ingredients blend more smoothly, resulting in better texture.
- Chill the dough – Allowing the dough to chill prevents spreading during baking, leading to thicker cookies.
- Don’t overbake – Keep an eye on your cookies; they should look set but still soft when you take them out of the oven.
- Sift powdered sugar – Sifting ensures no lumps in your marshmallow cream frosting, making it smooth and easy to spread.
- Store properly – Keep assembled Oatmeal Cream Pies in an airtight container in the refrigerator to maintain freshness.

Best Side Dishes for Oatmeal Cream Pies
Oatmeal Cream Pies can be paired with many side dishes to create a well-rounded meal or snack. Here are some great options:
- Fresh Fruit Salad – A mix of seasonal fruits adds freshness and balances out the sweetness of the pies.
- Vanilla Yogurt – The creamy texture pairs beautifully with Oatmeal Cream Pies while adding a tangy flavor contrast.
- Coffee or Tea – A warm beverage enhances the comforting flavors of cinnamon and oats, making for a cozy treat time.
- Nut Mix – A crunchy nut mix provides a nice contrast in texture and adds healthy fats to your snack.
- Chocolate Milkshake – For chocolate lovers, this rich drink complements the oatmeal cookies perfectly.
- Cheese Platter – Pairing with mild cheeses can balance sweetness while providing a savory element to your dessert table.
Common Mistakes to Avoid
Making homemade Oatmeal Cream Pies can be a delightful experience, but it’s important to avoid common pitfalls. Here are some mistakes to watch out for:
- Using cold ingredients: Starting with cold butter or eggs can result in uneven mixing and a denser cookie. Always bring your butter and eggs to room temperature beforehand.
- Overmixing the dough: Overmixing can lead to tough cookies. Mix until just combined to keep them soft and chewy.
- Not chilling the dough: Skipping the chilling step can cause cookies to spread too much while baking. Chill the dough for at least 15 minutes before scooping.
- Incorrect measuring of flour: Packing flour too tightly can lead to dry cookies. Use the spoon-and-level method or a kitchen scale for accuracy.
- Baking at the wrong temperature: An oven that is too hot or too cool can affect baking time and texture. Always preheat the oven and use an oven thermometer for best results.
