- 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

For the Marshmallow Cream Frosting

- 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 this mixture aside.
Step 2: Cream the Sugars and Butter
In a mixer, beat the unsalted butter with both sugars on high speed for about 2 minutes until creamy and well combined.
Step 3: Add Eggs and Flavorings
Add in the vanilla extract, molasses, and eggs. Mix on medium speed until everything is fully combined.
Step 4: Combine Dry Ingredients
Gradually add the dry ingredients to the wet mixture. Mix on low speed until everything is just incorporated.
Step 5: Chill the Dough
Chill the dough in the fridge for about 15 minutes while you preheat your oven to 350°F. Line two baking sheets with parchment paper.
Step 6: Scoop Cookies
Using a cookie scoop, portion out dough to form approximately 36 cookies (around 3 dozen). Place about 12 cookies per baking sheet. Return remaining dough to the fridge between batches.
Step 7: Bake
Bake for 8-9 minutes or until just set. Allow cookies to cool on the baking sheet for about 4 minutes before transferring them to a wire rack to cool completely.
Step 8: Make Marshmallow Cream Frosting
In a mixer, beat together unsalted butter and marshmallow fluff on high speed for approximately 3 minutes until light and fluffy. Add powdered sugar, vanilla extract, and salt; mix on low until combined. Then beat on high for another 4 minutes until airy and spreadable.
Step 9: Assemble the Cream Pies
Spread or pipe marshmallow frosting onto one flat side of a cooled cookie. Top with another cookie and gently press together.
Step 10: Chill Before Serving
Chill assembled cookie sandwiches in the freezer for at least 10 minutes before serving. If you prepare ahead of time, store leftovers in the refrigerator.

How to Perfect Oatmeal Cream Pies
Creating the perfect Oatmeal Cream Pies requires attention to detail. Here are some tips to ensure your cookies turn out just right.
- Bold Measuring: Use a kitchen scale or spoon and level flour accurately; too much flour can lead to dry cookies.
- Bold Temperature Control: Bring butter and eggs to room temperature before mixing for better texture.
- Bold Chilling Dough: Chill your cookie dough before baking; this helps prevent spreading and maintains shape.
- Bold Baking Time: Keep an eye on your cookies; they should be set but still soft when you take them out of the oven.
- Bold Storage: Store leftover cookies in an airtight container in the refrigerator to maintain freshness.

Best Side Dishes for Oatmeal Cream Pies
Oatmeal Cream Pies can be served alongside various side dishes that add extra delight to your dessert experience. Here are some great options.
- Fresh Fruit Salad: A mix of seasonal fruits brightens up the plate and adds freshness.
- Yogurt Parfait: Layer yogurt with granola and berries for a creamy, crunchy contrast.
- Nut Mix: A handful of mixed nuts provides a savory balance to the sweet flavors of oatmeal cream pies.
- Cheese Platter: Include some mild cheeses, like brie or gouda, for an unexpected yet delightful pairing.
- Chocolate Covered Strawberries: These sweet bites complement the cinnamon spice perfectly.
- Vanilla Ice Cream: Serve a scoop on the side or under the pie for a classic dessert combination.
Common Mistakes to Avoid
When making Oatmeal Cream Pies, it’s easy to overlook some key details. Avoid these common mistakes for the best results.
- Incorrect Flour Measurement: Using too much flour can lead to dry cookies. Always spoon and level your flour or use a kitchen scale for accuracy.
- Skipping Room Temperature Ingredients: Cold butter and eggs can prevent proper mixing. Take them out two hours before baking to reach room temperature.
- Not Chilling the Dough: Failing to chill your dough can result in cookies that spread too much. Chill for at least 15 minutes before baking.
- Overmixing the Batter: Overmixing can make cookies tough. Mix just until ingredients are combined for soft, chewy cookies.
- Ignoring Baking Time: Baking too long can lead to hard cookies. Keep an eye on them and remove when they’re just set.
Storage & Reheating Instructions
Refrigerator Storage
- Store Oatmeal Cream Pies in an airtight container.
- They will last up to 5 days in the fridge.
Freezing Oatmeal Cream Pies
- Wrap individual pies tightly in plastic wrap or aluminum foil.
- Freeze for up to 3 months for best quality.
Reheating Oatmeal Cream Pies
- Oven: Preheat to 350°F and heat for about 5-7 minutes until warmed through.
- Microwave: Heat one pie at a time for 10-15 seconds, just enough to warm it without melting.
- Stovetop: Place in a covered skillet over low heat for a few minutes, turning occasionally.

Frequently Asked Questions
How do I make the cookies chewier?
To achieve chewier Oatmeal Cream Pies, avoid overbaking. Remove them from the oven when they are still slightly soft in the center.

You can mix in chocolate chips, nuts, or dried fruit into the cookie dough for added flavor and texture.

Store leftover Oatmeal Cream Pies in an airtight container in the fridge for up to 5 days or freeze them for longer storage.
