Ingredients

- 1 cup brown sugar (light or dark), packed
- ½ cup white granulated sugar
- 1 teaspoon pure vanilla extract
- ½ tablespoon molasses (not blackstrap)
- 2 large eggs, room temperature
- 1 ¾ cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon salt

- 3 cups old fashioned oats
For the Marshmallow Cream Frosting
- 1 cup unsalted butter, room temperature
- 7 oz marshmallow fluff/cream
- 1 cup powdered sugar, sifted

- ¼ teaspoon salt

How to Make Oatmeal Cream Pies
Step 1: Prepare the Cookie Dough
In a large bowl, whisk together the flour, baking soda, salt, cinnamon, pumpkin pie spice, and oats. Set aside.
Step 2: Cream Butter and Sugars
In a mixer, beat the butter along with brown sugar and granulated sugar on high speed for about 2 minutes until it becomes creamy.
Step 3: Add Wet Ingredients
Add the vanilla extract, molasses, and eggs to the creamed mixture. Mix on medium speed until everything is fully combined.
Step 4: Combine Dry Ingredients
Gradually add in the dry ingredients from Step 1. Mix on low speed until just incorporated; avoid overmixing.
Step 5: Chill the Dough
Chill the dough in the fridge for about 15 minutes while preheating your oven to 350°F. Line two baking sheets with parchment paper.
Step 6: Scoop Cookies
Use a cookie scoop to form about 36 cookies (approximately 3 dozen). Place 12 cookies per baking sheet and keep leftover dough chilled between batches.
Step 7: Bake Cookies
Bake for about 8–9 minutes or until set. Let them cool on the baking sheet for around 4 minutes before transferring them to a wire rack to cool completely.
Step 8: Make Frosting
Using an electric mixer, beat together butter and marshmallow fluff on high speed for about 3 minutes until it’s light and fluffy.
Step 9: Add Sugar & Flavor
Add powdered sugar, vanilla extract, and salt into the frosting mixture. Mix on low speed until combined then increase to high speed for an additional 4 minutes until airy.
Step 10: Assemble the Pies
Spread or pipe the marshmallow frosting onto one flat side of a cooled cookie. Top it with another cookie to create a sandwich.
Step 11: Chill Before Serving
Chill these cookie sandwiches in the freezer for at least 10 minutes before serving. Store any leftovers in the refrigerator if made ahead of time.
How to Serve Oatmeal Cream Pies
Homemade Oatmeal Cream Pies are not only delicious but also versatile in how you can serve them. Whether for a party, a dessert after dinner, or simply as a sweet treat, there are plenty of creative ways to enjoy these delightful sandwiches.
With a Glass of Milk
- Pairing your oatmeal cream pies with a cold glass of milk enhances the flavors and adds creaminess. The milk complements the sweetness perfectly.
As Party Favors
- Package individual oatmeal cream pies in decorative bags or boxes. They make great party favors for birthdays or gatherings, allowing guests to take home a nostalgic treat.
Warmed Up
- Lightly warm the oatmeal cream pies in the microwave for about 10 seconds. This makes the marshmallow frosting extra gooey and the cookies slightly softer.
With Ice Cream
- Serve oatmeal cream pies alongside a scoop of vanilla ice cream. Create an indulgent dessert experience by sandwiching ice cream between two cookies.
How to Perfect Oatmeal Cream Pies
To achieve the best results when making oatmeal cream pies, follow these essential tips for perfect texture and flavor.
- Chill the Dough: Refrigerating the dough for at least 15 minutes helps prevent spreading while baking, ensuring thicker cookies.
- Measure Flour Correctly: Use the spoon-and-level method or a kitchen scale to accurately measure flour. Too much flour can lead to dry cookies.
- Room Temperature Ingredients: Always use room temperature butter and eggs for a smoother batter that incorporates air better, yielding fluffy cookies.
- Don’t Overmix: Mix until just combined after adding dry ingredients. Overmixing can lead to tougher cookies due to gluten development.

Best Side Dishes for Oatmeal Cream Pies
While oatmeal cream pies are sweet enough on their own, you might want to consider some side dishes that complement their flavors. Here are some tasty suggestions to serve alongside your treats.
- Fresh Fruit Salad: A refreshing mix of seasonal fruits balances out the sweetness of the cream pies with natural tartness.
- Chocolate-Dipped Strawberries: These provide a rich contrast and add an elegant touch when served as part of dessert platters.
- Coffee or Espresso: A cup of coffee pairs wonderfully with oatmeal cream pies, enhancing their spices and sweetness.
- Vanilla Ice Cream: Serving this classic side elevates your dessert experience; it can be served on its own or used as filling between cookie sandwiches.
- Nutty Granola Bars: These add crunch and texture while maintaining the wholesome feel of oats, creating a satisfying contrast.
- Yogurt Parfait: Layer yogurt with granola and berries for a light yet indulgent side that brings freshness and acidity to balance out the sweetness.
Common Mistakes to Avoid
Avoiding common mistakes can make your Oatmeal Cream Pies even better. Here are some pitfalls to watch out for:
- Incorrect flour measurement – Using too much flour can lead to dry cookies. Make sure to spoon and level the flour or use a kitchen scale for accuracy.
- Skipping the chilling step – Failing to chill the dough can result in overly flat cookies. Always refrigerate the dough for at least 15 minutes before baking.
- Overbaking the cookies – Baking them too long makes them hard instead of chewy. Keep an eye on the timer and remove them as soon as they’re set.
- Not letting cookies cool properly – Transferring cookies too soon can cause them to break. Allow them to cool on the baking sheet for 4 minutes before moving.
- Neglecting room temperature ingredients – Cold butter and eggs can affect the mixing process. Let these ingredients come to room temperature before you start.
Refrigerator Storage
- Store Oatmeal Cream Pies in an airtight container.
- They will last about 5 days in the refrigerator.
- Place parchment paper between layers to prevent sticking.
Freezing Oatmeal Cream Pies
- Wrap each pie individually in plastic wrap, then place in a freezer-safe bag.
- They can be frozen for up to 3 months.
- Thaw overnight in the refrigerator when ready to enjoy.
Reheating Oatmeal Cream Pies
- Oven – Preheat to 350°F, place pies on a baking sheet, and heat for about 5 minutes until warm.
- Microwave – Heat one pie on medium power for 10-15 seconds; avoid overheating as it may make them tough.
- Stovetop – Use a non-stick skillet over low heat; place pies inside and cover for 1-2 minutes until warmed through.
