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!




SOO GOOD!!! Everyone loved them! Totally a level up on Little Debbie’s recipe, but still super nostalgic and delicious:)
Just made these for my daughters bake sale, and I also subbed the shortening for butter. My question is, can I still leave them in a airtight container at room temperature? Or because there is dairy, do they need to be refrigerated? I need to bring them in tomorrow morning and then they are gonna serve them up on Saturday. Do you think they will hold up?
Thanks!
Hi Grace!
Made with butter, they should still be fine at room temperature for 3-4 days. :)
I made this one time before and I swear it worked perfectly. Today, I made 3 different batches and the cookies turned out flat and greasy each time. What the heck went wrong? I checked all ingredients and everything was good. Any input would be appreciated!
Hi Nikki,
Hmmm… It sounds like your oven might have veered off temperature since the last time you made them. Try hanging a new oven thermometer in the center of the oven to test the temp. Then pull up instructions online to recalibrate the oven. (It’s usually pretty easy to do.) Hope this helps!
Was your baking powder fresh? That could result in flat cookies too.
This recipe is pure gold ! I’ve been looking for a good oatmeal cookies recipe for so long and they never turned out as tasty as expected…until I found this recipe ! It’s so easy and quick to make, tasteful, yummy. Everyone loved this cookies and we’re at the 3rd batch in 2 week :D It’s gonna stay in my bookmarks forever and ever. Thank you !
Great recipe! I will mention that since I am kinda on an egg buying “REVOLT” due to prices (I just can’t bring myself to pay 30 cents per egg)!! So, I decided to substitute 1/4 cup of applesauce per egg and they turned out just the right kind of sweet and chewy. The family loved them!
Delicious! The filling is so creamy. Even the non gluten free house members love these.
Followed the tips from other reviews and did a double batch of cookies to one batch of frosting and still had a smidge of frosting left over. I didn’t have a tablespoon sized scoop so I just used a tablespoon to portion the dough out and ended up with 28 cookie sandwiches in the end. Also did half butter half crisco for the frosting. Took them to the river for a day out with friends & kids and they were a smash hit with everyone, we were forcing ourselves to stop at 2 a person.
These are delish!! My fiancé couldn’t stop eating them and neither could I! I made them twice after realizing I had leftover crème filling that I put in the fridge to save for a gluten free batch. The only issue is mine flatten out severely, and become so thin! I even put the second batch of dough in the fridge for 20 mins before separating to balls and it still didn’t help. I only baked for 7 mins, and 6 mins the next time. Either way I will be making these again very soon because they do not last long!
Hello! Not the OP here but I recently had this problem with my cookies and realized it was likely due to expired baking soda/powder. Hope that helps!
I made this recipe this weekend. Super easy. It is FABULOUS! My kids will not stay out of them. I did double the cookie recipe. And I used butter instead of shortening in the filling. It is what I have been looking for! Thank you for such an amazing recipe!
I make this recipe all the time! Thought I’d share I made it as a “Valentine’s day” dessert yesterday and colored the cream filling pink to fit the holiday! It turned out so cute ☺️ even added some red sprinkles in some!
These are fantastic! I have a gas convection range and cooked the minimum noted time and the cookies were perfect! I shared and everyone raved about them. Like others noted, the icing is definitely enough for about 2 batches of the cookies. I just cooked one set to start and put the icing in the fridge and plan to make a second batch. These did not last long. Great recipe as noted!!
This recipe was delicious! I will say to bake the cookies for 10 minutes so it’ll hold better, but they were still great!
I made the filling with butter instead of shortening and oh my! Much more flavorful and I only used 3 sticks (1 1/2 cups) of butter instead of 4 (2 cups) (I doubled the recipe).
I also made 2 double batches and 1 regular batch of the cookies (50 sandwiches) and I had PLENTY of filling.
It calls for 1/2 cup butter…. 1 stick. Seems you may have added even more than double.
She was referring to replacing the shortening in the creme (which she doubled) from 2 cups to 1.5 butter
