These oatmeal cream pies are just like the Little Debbie's versions but BETTER. They are soft oatmeal cookies loaded with cinnamon and pumpkin pie spice. It is filled with a marshmallow fluff frosting. They are soft and chewy cookies that are super delicious. These would be a perfect alternative for kids' lunches!
Little Debbie's Cookies
When I was a kid, and now as an adult, I loved the Little Debbie oatmeal creme pies. They were so soft, and very addicting!
I wanted to create a homemade version that wasn't full of preservatives and that little kids would love more than the store-bought version!
How To Make Oatmeal Dough
These homemade oatmeal cream pies are full oats and cinnamon. The trick to keeping them soft is a little bit of molasses.
- Mix the dry ingredients- Mix the all purpose flour, baking soda, and salt together in a mixing bowl. Then, add the quick oats. If you have rolled oats, blend them in a food processor a few times for best results. Then, measure out 3 cups.
- Beat unsalted butter- Use an electric mixer, either stand mixer with paddle attachment or hand mixer, to beat the room temperature butter, brown sugar, and sugar. It should be very fluffy and light in color.
- Add the wet ingredients- Add the vanilla extract and molasses. I use this one. Don't use blackstrap because it is too dark. Then, add in the large eggs and mix until combined. There shouldn't be any butter chunks remaining.
- Mix in the dry ingredients- Mix in the dry ingredients until combined.
- Chill the dough- Chill the dough for 45 minutes to prevent spreading.
Scooping The Dough
Use this cookie scoop to scoop the dough. This will make 3 dozen chewy oatmeal cookies before you sandwich them. A large cookie scoop can make a thicker cookie, which can cause the frosting to squeeze out when you bite into it. Place the cookie dough in the fridge while the oven preheats.
Place 12 cookies per cookie sheet lined with parchment paper. Keep the other cookie dough balls in the fridge while they bake. To prevent spreading, use parchment paper and NOT silicone baking mats. When they are done baking transfer them to a wire rack to cool.
Marshmallow Fluff Frosting
When I was deciding what to fill these cookies, I thought regular frosting would be too sweet and boring. Marshmallow fluff is magic, and it has the closest flavors to the original cookies.
First, let the butter sit on the counter for 30 minutes to get slightly cold. Slightly cold butter is best to keep a firmer frosting. Cold butter, is too hard to blend into the frosting.
Use a mixer to beat the butter on high in a large bowl. Once fluffy, add in the entire jar of marshmallow creme / fluff. Mix until combined and back to a more "fluffy" texture.
Next, add in the powdered sugar and vanilla. To prevent a gritty frosting, sift the powdered sugar first.
Filling The Cookies
I used a 1M Wilton tip and piping bag to pipe the frosting on the cookies. Leave a tiny bit of the edge uncovered for the frosting to spread once you place the other cookie on top.
If you try to bite the cookies right away, the filling will be squished right out. Either chill in the fridge for an hour or place in the freezer for 15 minutes before eating your cookie sandwiches.
Storing The Cookies
Keep these oatmeal cream pies in the fridge in an airtight container up to 5 days if you didn't eat them all in a single day.

I made these for my husband to take on a fishing trip with his brothers. That was a mistake- I should have kept them ALL TO MYSELF! 😂
These are crazy delicious. Fairly easy to put together. I’ll be making them again for sure.
