Homemade Oatmeal Cream Pies are soft, chewy oatmeal cookies sandwiched around a smooth, sweet vanilla cream filling. They are a delicious homemade version of the classic oatmeal sandwich cookie, with warm cinnamon flavor, tender oats, and a creamy center.
These cookies are perfect for lunchboxes, afternoon snacks, bake sales, parties, or whenever you want a nostalgic homemade dessert. The cookies stay soft and chewy, while the cream filling adds just the right amount of sweetness.
Ingredients
For the Oatmeal Cookies
- 1 cup (226 g) unsalted butter, softened
- ¾ cup (150 g) brown sugar
- ½ cup (100 g) granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 1½ cups (150 g) old-fashioned rolled oats
- 1¼ cups (160 g) all-purpose flour
- 1 teaspoon baking soda
- ½ teaspoon ground cinnamon
- ¼ teaspoon salt
- ¼ teaspoon ground nutmeg, optional
For the Cream Filling
- ½ cup (113 g) unsalted butter, softened
- 1½ cups (180 g) powdered sugar
- 1 teaspoon vanilla extract
- 2 tablespoons heavy cream or milk
- Pinch of salt
Instructions
1. Prepare the Oven
Preheat your oven to 350°F (175°C).
Line two baking sheets with parchment paper or silicone baking mats. This prevents the cookies from sticking and makes cleanup easier.
2. Cream the Butter and Sugars
Place the softened butter, brown sugar, and granulated sugar in a large mixing bowl.
Beat for approximately 2–3 minutes, until the mixture becomes light and creamy.
Properly softened butter is important. It should be soft enough to mix easily but should not be melted.
3. Add the Eggs and Vanilla
Add the eggs one at a time, mixing well after each addition.
Add the vanilla extract and mix until everything is smooth and well combined.
Scrape down the sides of the bowl as needed.
4. Combine the Dry Ingredients
In a separate bowl, whisk together:
- All-purpose flour
- Rolled oats
- Baking soda
- Cinnamon
- Salt
- Nutmeg, if using
Mixing the dry ingredients separately helps distribute the baking soda and spices evenly throughout the dough.
5. Make the Cookie Dough
Gradually add the dry ingredients to the butter mixture.
Mix on low speed just until the ingredients are combined.
Do not overmix the dough. Overmixing can make the cookies less tender.
The finished dough should be soft and slightly thick.
6. Portion the Cookies
Using a cookie scoop or tablespoon, place small portions of dough onto the prepared baking sheets.
Leave approximately 2 inches (5 cm) between each cookie because the dough will spread as it bakes.
For sandwich cookies, try to make the portions similar in size so the finished oatmeal cream pies fit together nicely.
7. Bake
Bake the cookies for approximately 9–12 minutes.
The edges should look set while the centers still appear slightly soft.
Do not overbake them. The cookies will continue to firm up as they cool, and keeping them slightly soft in the center gives the finished oatmeal cream pies their classic chewy texture.
8. Cool the Cookies
Allow the cookies to cool on the baking sheet for about 5 minutes.
Then carefully transfer them to a wire rack to cool completely.
The cookies must be completely cool before adding the cream filling. If they are still warm, the filling can become soft and difficult to handle.
Making the Cream Filling
9. Beat the Butter
Place the softened butter in a clean mixing bowl.
Beat for approximately 2 minutes, until smooth and creamy.
10. Add Powdered Sugar
Gradually add the powdered sugar while mixing on low speed.
Once the sugar is incorporated, increase the speed and beat for another 2–3 minutes.
The filling should become light and fluffy.
11. Add Vanilla and Cream
Add the vanilla extract, heavy cream or milk, and a small pinch of salt.
Beat again until the filling is smooth and creamy.
If the filling is too thick, add another teaspoon of cream or milk.
If it is too thin, add a little more powdered sugar.
Assemble the Oatmeal Cream Pies
12. Add the Filling
Turn half of the cooled oatmeal cookies upside down.
Using a piping bag, zip-top bag with the corner snipped off, or a small spoon, place a generous amount of cream filling in the center of each cookie.
Do not spread the filling all the way to the edge because it will spread when the second cookie is added.
13. Sandwich the Cookies
Place another oatmeal cookie on top of the filling.
Press gently until the cream reaches close to the edges.
Repeat with the remaining cookies and filling.
Your homemade oatmeal cream pies are now ready to enjoy.
Tips for Soft and Chewy Cookies
Don’t overbake: The centers should still look slightly soft when the cookies come out of the oven.
Use softened butter: Soft butter creates a better cookie texture and helps the ingredients combine properly.
Measure flour carefully: Too much flour can make the cookies dry and cakey.
Use rolled oats: Old-fashioned rolled oats provide a pleasant chewy texture.
Cool completely: Make sure the cookies are completely cool before adding the filling.
Make equal-sized cookies: Similar-sized cookies make assembling the sandwich pies much easier.
Flavor Variations
Chocolate Oatmeal Cream Pies
Add 2 tablespoons of unsweetened cocoa powder to the cookie dough for a chocolate variation.
Maple Oatmeal Cream Pies
Add 1 teaspoon of maple extract to the cream filling for a warm maple flavor.
Extra Cinnamon
If you love cinnamon, increase the cinnamon slightly or add a little cinnamon to the cream filling.
Chocolate Chip
Add a small amount of mini chocolate chips to the oatmeal cookie dough for extra texture and chocolate flavor.
Raisin Oatmeal Cream Pies
For a traditional oatmeal-cookie twist, add finely chopped raisins to the dough.
Storage
Store the finished oatmeal cream pies in an airtight container.
They can be kept at room temperature for approximately 2–3 days, provided the filling ingredients are suitable for room-temperature storage.
For longer storage, refrigerate them in an airtight container for approximately 5–7 days.
Allow refrigerated cookies to sit at room temperature for a few minutes before serving so the filling becomes soft and creamy again.
Freezing
These cookies can also be frozen.
Place assembled oatmeal cream pies in a freezer-safe container with parchment paper between the layers.
Freeze for up to approximately 2–3 months.
To serve, transfer them to the refrigerator and allow them to thaw. Then let them sit at room temperature briefly before eating.
You can also freeze the baked cookies separately and fill them after thawing.

Final Thoughts
These Homemade Oatmeal Cream Pies combine everything you want in a nostalgic sandwich cookie: soft oatmeal cookies, warm cinnamon flavor, and a sweet, creamy vanilla center.
The key to getting the best texture is to avoid overbaking the cookies. Take them out when the edges are set but the centers still look slightly soft. Once cooled and filled, they become chewy, tender, and wonderfully satisfying.
Make them for a weekend baking project, prepare a batch for the family, or keep a few in the freezer for whenever a homemade sweet treat is needed.
