These Homemade Oatmeal Cream Pies are a delicious & nostalgic treat I’ve been making for many years. They are my husband’s second favorite dessert (second only to homemade eclairs), and everyone who tries them falls in love.

This homemade version is even better than the well-known, store-bought variety. Two soft, flavorful oatmeal cookies are generously filled with an irresistible homemade buttercream filling. Also try these oatmeal cookies, oatmeal raisin cookies and peanut butter oatmeal cookies!

This oatmeal cream pie recipe makes enough to feed a crowd. And they can be made ahead and frozen until you’re ready to serve them, which is ideal for entertaining.

Oatmeal Cream Pies Ingredient Notes

As always, I suggest making this recipe as written for the best results. But here are a few notes.

labeled ingredients in this Homemade Oatmeal Cream Pies recipe

Salted Butter. unsalted butter or vegan butter are good substitutes.
Light Brown Sugar. for a bolder molasses taste, use dark brown sugar.
Granulated Sugar. use white sugar or organic cane sugar.
Molasses. use unsulphured or light molasses– not blackstrap molasses.
All-purpose flour. make them gluten-free by using a 1:1 all purpose gluten-free flour blend.
Old Fashioned Oatmeal: For the perfect, chewy texture use old-fashioned (or rolled) oats. You can use quick oats, just note it will change the texture of the cookies.
Cinnamon Chips. These are next-level delicious and make these oatmeal cream pies extraordinary. If you can’t find them, you can omit, but I don’t recommend it.

How to Make Oatmeal Cream Pies

Let’s walk through making this oatmeal cream pies recipe step by step, and don’t forget to watch the video.

Make the Oatmeal Cookies

Begin by combining the dry ingredients in a medium bowl, then set them aside to use later.

Next, cream the butter & sugars together in the bowl of a standing mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer.

Next, beat the dry ingredients into the wet ingredients.

Then, stir in the oats and cinnamon chips on low speed until evenly distributed throughout the dough.

At this point you can chill the dough to bake later or the next day, but it’s not necessary.

NOTE: The dough is sticky. Don’t let that worry you, the dough is a bit sticky but it’s ok! it yields a very soft delicious cookie perfect to use in oatmeal cream pies.

Use a cookie scoop to measure out 1 Tablespoon portions of dough, roll them into balls and place them evenly spaced on the prepared baking sheets. Since we are making sandwiches, it’s important that the cookies are the same size and shape.

The cookies flatten and spread while baking, so make sure to spread out the dough balls.

Then, bake the oatmeal cookies in the preheated oven until the center is just barely set (about 10-12 minutes).

Remove the cookies from the oven and let them cool on the pan for 5-10 minutes before transferring them to a wire rack to cool completely.

Make the Filling

While the cookies are cooling, make the filling.

Begin by beating the butter and powdered sugar together in the bowl of a standing mixer fitted with the whisk attachment, or in a large bowl with a handheld mixer.

Then, add the vanilla and cream and beat until smooth.

Assemble the Oatmeal Cream Pies

Once the cookies are cooled and the filling is made, it’s time to assemble the oatmeal cream pies.

Begin by pairing similar size and shaped cookies together to make into sandwiches.

Then, spread about 1 Tablespoon of the filling between two cookies, putting the bottom sides together. Repeat until all the cookies are filled and the pies are assembled.

Once assembled, chill the cookies in the refrigerator, or let them set at room temperature.

There is enough filling

No matter how many times I make these oatmeal cream pies, I worry there won’t be enough frosting, but there always is! Use 1 Tablespoon per cookie to begin with, and go back and use the leftovers on any cookies might not have gotten enough.

How to Store Oatmeal Cream Pies

Store the oatmeal cream pies in an airtight container in the refrigerator. I suggest serving them only slightly chilled or at room temperature, so remove them from the refrigerator about 30 to 60 minutes before serving.

Freeze

Store the cream pies in an airtight container in the freezer. Separate the layers with wax or parchment paper to avoid sticking.

Let the oatmeal cream pies thaw at room temperature for 1-2 hours before serving. Do not microwave or warm them in the oven.
