Sommer’s Recipe Notes
What was your favorite childhood treat? Swiss Cake Rolls, Twinkies, Ding Dongs? Well, I was an Oatmeal Cream Pie Cookie kind of girl.
These tender Homemade Oatmeal Cream Pies are the perfect treat to satisfy nostalgic cravings no matter the time of day. Plus, they are much better than the store-bought variety.
Why You’ll Love This Oatmeal Cream Pie Recipe
- Heavenly texture – The soft pliable cookies are sandwiched together with fluffy cream filling, just how you remember them, taste and texture both.
- The perfect treat – Homemade Oatmeal Cream Pies pack well in lunch boxes to provide a big smile when your little someone discovers their treat. That makes them a double win for both parent and child in my opinion.
So let’s learn how to make oatmeal cream pies right at home! Ready to get started?

Ingredients and Tips
- Rolled oats – You can also use quick oats.
- Dry ingredients – You’ll need all-purpose flour, baking soda and baking powder.
- Sugar – For the cookies, use brown sugar, and for the filling you’ll need powdered sugar.
- Butter – Use melted, unsalted butter.
- Vanilla extract – You will need a high-quality vanilla extract.
- Cocoa powder – Use the unsweetened variety.
- Cinnamon – To get that warm, aromatic flavor, use powdered cinnamon.
- Marshmallow fluff – This creates the filling’s gooey signature quality.
Recipe Variations and Dietary Swaps
- Chocolate – Sprinkle some mini chocolate chips into the cookie batter, or drizzle some chocolate sauce over the prepared cream pies as a garnish.
- Pumpkin – Mix some pumpkin puree into the cookie dough for a fun fall twist.
- Ice cream – Swap the cream pie layer with vanilla ice cream.
- Gluten-free – Use GF oats and flour.
- Jumbo size – To make extra jumbo oatmeal creme pies, make larger cookie dough balls (and increase baking time)!
- Raisins – Mix in some plump raisins for extra sweetness.

How To Make Oatmeal Cream Pies
Tips for Success – For super soft and chewy cookies, make sure you don’t over-mix the dough! That can create tough cookies. Also, don’t over bake the cookies! Cookies will look slightly underdone when they are ready to take out of the oven. Make sure you don’t leave them in the oven too long, or they will be too hard.

Storage Notes
- Storing Leftovers – Store leftover pies in an airtight container or wrap in plastic wrap at room temperature for up to 3 days. Otherwise, place in the refrigerator for up to 5 days. You can also freeze these (tightly wrapped). Make sure to thaw before serving.
Serving Suggestions
I love to serve these classic cream pies at potlucks or picnics alongside a glass of milk, hot cocoa or even with a generous scoop of vanilla ice cream…for some extra sweetness. Each bite is reminiscent of those childhood favorite little Debbie oatmeal creme pies..

Ingredients
For the Oatmeal Cookies:
- 1 cup packed brown sugar
- 1/2 cup melted butter
- 1 large egg
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon cinnamon
- 1 1/2 teaspoons cocoa powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup rolled oats
For the Cream Filling:
- 1 cup vegetable shortening
- 1 cup powdered sugar
- 2 teaspoons vanilla extract
- 7.5 ounces marshmallow fluff (1 jar)
Instructions
For the Cookies:
- Preheat the oven to 350 degrees F. Line cookie sheets with parchment paper. Sift the dry ingredients into a medium bowl and set aside.
- Use an electric mixer to cream the brown sugar, butter, egg, and vanilla. Once smooth, slowly add the dry mixture to the wet mixture until well combined. Stir in the oats.
- Use a tablespoon-sized scoop to form equal dough balls. Allow them plenty of space to spread. Bake for 7-9 minutes. Let the cookies cool completely before moving off the parchment paper.
For the Filling:
- Cream the shortening, powdered sugar, and vanilla together until smooth. Mix in the marshmallow fluff.
To Assemble:
- Match up two cookies that are of equal size and shape. Turn the bottom cookies over. Use a piping bag (or zip-bag with the corner cut off) to pipe the filling onto the bottom cookie. This is much easier than trying to spread it. Add the top cookie of each cream pie and press down.

Frequently Asked Questions
Yes, you can! It will change the flavor a tad, but will definitely work the same. Butter will make a nice soft filling, while coconut oil will make the filling a little stiffer than the traditional “frosting” filling.
If you are in a time pinch, you can simply just use store-bought marshmallow fluff as the filling, but it won’t be as fluffy or as sweet as if you doctor it up like I did!

Made before and these are amazing!! I am hoping to bake again but make ahead & freeze. Is is possible to freeze both the dough & the frosting? Or better to make the cookies in advanced & freeze the already baked cookie?
Can you use jet puffed instead of marshmallow fluff? I’m excited to make these!
Hi CJ,
Yes, you can. Let me know how they turn out!
The cookie recipe turned out lovely!! – but the creme filling was a miss. It just tastes like shortening. I was planning to bring these to an event right after making but decided against it. It’s somehow sweet and yet flavourless
Absolutely delicious! If I could give more than 5 stars, I would! We don’t buy many pre-packaged treats, but my husband was craving oatmeal cream pies so I whipped these up and I am so glad I did. This is a new favorite and worlds better than anything you can buy at the store. Sorry Little Debbie. HAHA
Oh yeah, I forgot to add, the filling recipe makes more than enough filling for all of the cookies! I used only 1/3 of the ingredients because I only had 1/3 cup of shortening and it was plenty :)
So beyond happy I found this recipe. I did make them dairy free with dairy free butter because my husband is allergic and they are amazing. They were extremely easy to make and I will definitely be making them again. Not sure if it was the dairy free butter but mine didn’t form into balls when I put them on the cookie sheet. They still turned out great though. Thank you for this recipe!
I just made these and they’re good but I thought they were too sweet. My husband wanted me to cut the sugar in half next time. Other than that they were great. Thank you so much for sharing!
I made them a second time and did half of the vanilla in the cookie and left everything else the same. We thought they came out perfect. So delicious! Thank you for sharing this recipe. It’s a new family favorite!
Hello! So excited to try these!! Could I substitute quick oats for rolled oats in this recipe?
Hi Taylor,
Yes, you can. Happy Baking!
Should I use unsalted butter? I noticed you add salt.
Hi Melissa!
Yes, the recipe calls for unsalted butter. If you only have salted butter, you can reduce the salt by half.
These are sooo much better than store bought. Everyone that has ever tried these goes crazy for them. Today is my husband’s birthday and instead of a cake, he has requested these! Thank you for this awesome recipe!
These cookies brought me back to my kindergarten days!! Wow how amazing and delicious!! My kids DEVOURED these almost instantly and didnt believe me when I said I made it!
Holy smokes! I made these for a family down the road, and I tried one before taking them to them… now I have to make some for us. Haha. Thank you!
My kids and their friends all loved these! So delicious!
this is the best thing ever, and makes me feel better about eating this copycat little debbie recipe
