If there’s one cookie that brings together nostalgia, warm spice, and creamy indulgence all in one bite, it’s these Easy Spiced Eggnog Oatmeal Cream Pies. I grew up eating those classic oatmeal cream pies from the store, but once I started baking my own, there was no going back. These homemade treats are on another level—soft and chewy oatmeal cookies sandwiched with a silky, eggnog-spiced buttercream that makes them taste like Christmas morning.

I love making these during the holidays, but they’re honestly good enough to enjoy year-round if you’re a fan of cozy flavors. The cinnamon, nutmeg, and hint of rum extract in the filling are what set them apart, creating a spiced eggnog flavor that balances beautifully with the hearty oats.

Why You’ll Love These Easy Spiced Eggnog Oatmeal Cream Pies

These cream pies are everything you want in a holiday treat: soft, chewy, warmly spiced, and filled with a creamy center that’s rich with eggnog flavor. They’re easy to make but deliver bakery-style results, and they keep well, so you can make them ahead of time for parties or gifting. Even people who don’t typically like eggnog have fallen for these cookies!

What Kind of Oats Should I Use?

Old-fashioned rolled oats are your best bet for these cookies. They give the cookies that signature chewy texture and heartiness. Quick oats tend to make them too soft, while steel-cut oats won’t cook down enough. If you’re after that perfect balance of chew and softness, go for the rolled oats every time.

Options for Substitutions

Butter: You can use vegan butter sticks for a dairy-free version.
Eggnog: Try a dairy-free or vegan eggnog if you’re avoiding dairy. Almond or oat-based nogs work well.
Rum Extract: You can skip it or swap it for vanilla extract, but it does give the filling that classic eggnog punch.
Spices: Adjust the cinnamon and nutmeg to taste. Add a dash of cloves for deeper warmth.
Gluten-Free: Use a 1:1 gluten-free baking flour and certified GF oats to make them gluten-free without sacrificing texture.

Ingredients for These Easy Spiced Eggnog Oatmeal Cream Pies

Old-fashioned rolled oats: Provide the chewy, hearty texture that defines the cookies.
All-purpose flour: Gives the cookies structure and a tender crumb.
Brown sugar: Adds moisture and deep caramel notes that complement the spices.
Granulated sugar: Balances sweetness and helps with a soft cookie edge.
Eggs: Help bind the dough and add richness.
Unsalted butter: Delivers buttery flavor and moisture in both the cookies and the filling.
Baking soda: Ensures the cookies rise and stay soft.
Salt: Enhances all the warm flavors and balances the sweetness.
Ground cinnamon & nutmeg: Essential for that spiced oatmeal and eggnog flavor.
Vanilla extract: Adds a subtle warmth that supports the eggnog flavor.
Eggnog: Used in the cream filling, gives it a seasonal flavor and creamy consistency.
Powdered sugar: Used to create a smooth, pipeable buttercream.
Rum extract (optional): Deepens the eggnog flavor in the filling.

Step 1: Prep Your Oven and Pans

Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper. This prevents sticking and gives the cookies a uniform bottom.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking soda, salt, cinnamon, and nutmeg. Stir in the rolled oats. This ensures the spices are evenly distributed throughout the dough.

Step 3: Cream the Butter and Sugars

In a large mixing bowl, beat the butter, brown sugar, and granulated sugar until light and fluffy, about 2-3 minutes. This adds air into the mix, which keeps the cookies soft.

Step 4: Add Eggs and Vanilla

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract. The mixture should be smooth and slightly fluffy.

Step 5: Combine Wet and Dry

Gradually add the dry mixture into the wet, mixing on low speed just until combined. Do not overmix, or the cookies may turn tough.

Step 6: Scoop and Bake

Use a cookie scoop to drop even portions of dough onto the prepared baking sheets, about 2 inches apart. Bake for 10-12 minutes, until the edges are set and the centers look slightly underdone. Let them cool on the sheet for 5 minutes before transferring to a wire rack.

Step 7: Make the Eggnog Cream Filling

Beat softened butter in a bowl until creamy. Slowly add powdered sugar, then mix in eggnog, vanilla, and rum extract if using. Continue to beat until smooth and fluffy, about 2 minutes. Add more eggnog or sugar to adjust consistency if needed.

Step 8: Assemble the Cream Pies

Once cookies are completely cool, pipe or spoon the eggnog cream onto the flat side of half the cookies. Top with another cookie and gently press to sandwich.

How Long to Prepare the Easy Spiced Eggnog Oatmeal Cream Pies

Prep Time: Most of your time will go into prepping the dough and mixing the filling. Expect to spend about 20–25 minutes for measuring, mixing, and scooping.

Baking Time: Each batch bakes for around 10–12 minutes. If baking two sheets, rotate them halfway through for even browning. Cooling takes an additional 20–30 minutes before you can assemble.

Assembly: Once the cookies are cool, filling and sandwiching them takes about 10–15 minutes. All in all, plan for a total of around 1 hour, start to finish.

Tips for Perfect Oatmeal Cream Pies

Chill the dough if your kitchen is warm or if the dough seems too sticky—this helps prevent spreading.
Make sure cookies are completely cool before filling, or the buttercream will melt.
Use a piping bag for neat and even filling, or spoon it on and spread with an offset spatula.
For a fluffier filling, beat the butter longer before adding sugar.
Let the assembled pies rest in the fridge for 15–20 minutes to firm up before serving.

Watch Out for These Mistakes While Cooking

Overbaking the cookies: They should look slightly underdone in the center when you take them out. They’ll continue to set as they cool.
Not measuring flour correctly: Always spoon and level your flour to avoid dense cookies.
Skipping the cooling step: Filling warm cookies will lead to a runny mess.
Using cold butter for the filling: It won’t whip up light and fluffy. Let it soften first.
Too much eggnog in the frosting: It can make the filling runny—start with less and add gradually.

Storage Instructions

Room Temperature: Store the assembled cream pies in an airtight container at room temperature for up to 2 days. Keep them in a cool, dry place away from direct sunlight.

Refrigerator: For longer storage, place them in the fridge in a sealed container for up to 5 days. Let them sit at room temperature for 10 minutes before serving so the filling softens.

Freezing: You can freeze the cookies (unfilled) for up to 2 months. Wrap tightly in plastic and store in a freezer-safe bag. The filling can be made fresh when needed.
