Required Kitchen Tools
To make these delicious Midnight Oatmeal Creme Pies, you’ll need the following tools:

- Mixing Bowls: To separate the ingredients for the cookies and filling.
- Cookie Scoop or Tablespoon: For evenly portioning out the dough for perfect cookie sizes.
- Baking Sheets: For baking the cookies; line them with parchment paper or silicone mats to prevent sticking.
- Cooling Rack: To cool the cookies before assembling them into sandwiches.
- Measuring Cups and Spoons: For accuracy when adding the ingredients.

Ingredients
For the cookies, here’s what you’ll need to make the perfect chewy oatmeal cookie:
- Unsalted Butter (softened): Using softened butter ensures it incorporates well with the sugar, creating the perfect texture.
- Brown Sugar (packed): This adds a rich, molasses-like sweetness to the cookies, giving them that perfect flavor.
- Granulated Sugar: Adds sweetness and helps create the soft texture of the cookies.
- Eggs: Two large eggs to bind everything together and give the cookies their tender texture.
- All-Purpose Flour: The base of the dough, providing structure.
- Old-Fashioned Rolled Oats: These are essential for that chewy texture, and they give the cookies their signature oatmeal flavor.
- Baking Soda: Helps the cookies rise and gives them a soft, puffy texture.
- Cinnamon: A warm spice that complements the oatmeal and adds a comforting aroma.
- Salt: Balances the sweetness and brings out the flavor of the other ingredients.
- Vanilla Extract: A must for enhancing the flavor of the cookies.
Ingredients for the Cream Filling
For the cream filling, here’s what you’ll need:
- Unsalted Butter (softened): Again, softened butter ensures smooth and creamy filling consistency.
- Powdered Sugar (sifted): For sweetness and a smooth, light texture that won’t be too grainy.
- Marshmallow Fluff: This helps to create a light, airy filling that is easy to spread.
- Vanilla Extract: Adds flavor to the filling and ties everything together.
- Pinch of Salt: Just a touch to balance out the sweetness of the cream.

Step-by-Step Instructions
1. Make the Oatmeal Cookie Dough
Start by preheating your oven to 350°F (175°C) and lining two baking sheets with parchment paper or silicone baking mats.
In a large mixing bowl, cream together softened unsalted butter, brown sugar, and granulated sugar. Use an electric mixer or a stand mixer for this process. Beat for about 2 minutes or until the mixture is light and fluffy. The butter and sugar should be well combined, and you should see the texture become airy and light in color.
Add two large eggs, one at a time, and continue mixing. Make sure each egg is fully incorporated before adding the next. Once the eggs are added, mix in vanilla extract and beat until everything is well combined.
In a separate bowl, whisk together the all-purpose flour, baking soda, cinnamon, and salt. Gradually add this dry mixture to the wet mixture in the large bowl. Stir everything together until just combined.
Add in the old-fashioned rolled oats and stir with a spatula until evenly distributed. The dough will be thick, so make sure everything is well mixed.
2. Portion the Cookie Dough
Use a cookie scoop or tablespoon to drop the dough onto your prepared baking sheets. Make sure the cookies are spaced about 2 inches apart to allow for spreading while baking.
Press down lightly on each dough ball to flatten them slightly. This helps the cookies bake evenly and creates a nice surface for the cream filling later.
3. Bake the Cookies
Bake the cookies in your preheated oven for 10-12 minutes. The edges should be lightly golden, and the center will still look soft. It’s important not to overbake them, as they will firm up as they cool.
Once baked, remove the cookies from the oven and let them cool on the baking sheets for about 5 minutes. Afterward, transfer them to a wire rack to cool completely. This cooling step is essential because if you try to assemble the pies while the cookies are still warm, the filling will melt and make a mess.
2. Make the Cream Filling
While your oatmeal cookies are cooling, it’s the perfect time to make the sweet, fluffy cream filling. This filling is what takes these cookies from great to extraordinary, offering a rich, vanilla-sweet cream that pairs perfectly with the chewy oatmeal cookies.
In a medium-sized mixing bowl, begin by creaming together softened unsalted butter and marshmallow fluff. You can use an electric mixer to make this process easier, but a hand mixer will work just fine, too. Beat them together until the mixture is light, smooth, and airy—about 2 minutes.
Next, sift in the powdered sugar to avoid any lumps, and continue to beat the mixture on low speed. Gradually increase the speed as the powdered sugar begins to incorporate. Beat for about 3-5 minutes until the filling is smooth and fluffy.
Add a teaspoon of vanilla extract for an extra boost of flavor, and finish with a pinch of salt. The salt helps to balance the sweetness and enhances the flavor profile of the cream.
Once the cream filling is made, scrape down the sides of the bowl to make sure everything is mixed in, and set the filling aside.
3. Assemble the Midnight Oatmeal Creme Pies
Once your cookies are completely cooled, it’s time to assemble these delightful treats. The key to assembling them is to make sure the cookies are cool, otherwise, the filling might melt and become messy.
Turn half of your cooled cookies upside down (so the flat side is facing up). Using a spoon or a piping bag, scoop a generous amount of the cream filling onto the center of each upside-down cookie. Be generous—this filling is the heart of the pie, and the more the merrier!
Take the remaining cookies and gently press them onto the filling. You want to press lightly so that the filling spreads to the edges but doesn’t ooze out everywhere. The oatmeal cookies should form a sandwich around the cream, creating a delightful pie.
Repeat this process with the rest of the cookies and cream filling.
4. Chill and Serve
Once all of your oatmeal creme pies are assembled, place them on a tray and refrigerate them for about 30 minutes. This chilling step helps the filling set and gives the cookies a chance to soften slightly, making for a perfectly chewy, balanced bite.
Once chilled, your Midnight Oatmeal Creme Pies are ready to serve! Stack them on a platter or wrap them up individually for a gift that will surely impress anyone with a sweet tooth.

Variations for Midnight Oatmeal Creme Pies
While the classic version of these oatmeal cream pies is a crowd-pleaser, there are plenty of ways to switch things up to suit different tastes and occasions. Here are some fun ideas to personalize your oatmeal creme pies:
- Add Chocolate Chips: Mix some semi-sweet chocolate chips into the oatmeal cookie dough for an extra touch of chocolate flavor.
- Cinnamon Spice: Enhance the flavor with a teaspoon of pumpkin pie spice or apple pie spice instead of just cinnamon for a fall-inspired twist.
- Peanut Butter Filling: Swap out the marshmallow fluff for creamy peanut butter in the filling for a nutty variation that pairs wonderfully with the oatmeal cookies.
- Coconut: Add shredded sweetened coconut flakes to the filling or the cookie dough for an added texture and flavor.
- Colored Filling: For holidays or special occasions, tint the cream filling with a few drops of food coloring. It’s a simple way to make these pies more festive!
- S’mores Version: Fold in a handful of mini marshmallows into the oatmeal cookie dough, and use a marshmallow cream filling with a drizzle of chocolate syrup for a s’mores-inspired pie.
