Up-level a batch of homemade oatmeal cookies by sandwiching a sweet and fluffy filling between two cookies to create the best copycat version of a retro favorite – Oatmeal Cream Pies!
These Copycat Oatmeal Cream Pies take me back in time to school lunch box treats that included the original Little Debbie version of these sweet sandwich cookies. I was always so excited to see it and of course, eat it!
And now, I can make these anytime I want. Kids, as well as adults, find these oatmeal cream pies simply irresistible, and for good reason! Everyone loves the combination of the chewy oatmeal cookies that hold the sweet, buttery, and fluffy marshmallow filling. It makes the perfect handheld dessert for casual events, cookouts, potlucks, tailgating, and more.
Plus, they’re portable, so they’re great for on-the-go snacks or to tuck in lunch boxes. If you have kids, they’ll love them. If you have grandkids, they’ll always want to visit because you have the best treats! If there are adults around, they’ll love this delicious trip down memory lane.

Ingredients Needed

For The Cookie Dough
Flour – use regular all-purpose flour.
Quick Oats – you’ll get the best texture if you slightly pulse them in a food processor or a high-speed blender to make them even smaller.
Cocoa Powder – to flavor the cookie dough.
Leavening Agents – you’ll need cornstarch, baking powder, and baking soda.
Seasonings – you’ll need salt, ground cinnamon, and vanilla extract.
Butter – use either salted or unsalted, and set it out to soften before mixing.
Shortening – you’ll use this in both the cookie dough and the filling. It helps recreate the authentic texture and taste of the original cream pies.
Sweeteners – you’ll need both molasses and granulated white sugar for depth of taste and texture in the cookie dough.
Eggs – to help the cookie dough bind and stay moist.
Food Coloring: Red and yellow gel food coloring, which are optional, are added to the cookie dough to help recreate the original shade of the oatmeal cookies as they bake.
For The Cream Filling
Butter – use either salted or unsalted, and set it out to soften before mixing.
Shortening – when mixed with the butter, it helps recreate the authentic texture and taste of the original cream pies.
Powdered Sugar – to sweeten the filling.
Marshmallow Fluff – to add texture, fluffiness, and sweetness to the filling, just like the original version.

How To Make Copycat Oatmeal Cream Pies
Note: This is a summary of the recipe steps. For complete instructions, see the recipe card down below.
STEP 1: Preheat the oven to 350° F and line a cookie sheet with parchment paper. Set aside.
STEP 2: In a large mixing bowl, combine all the cookie dough dry ingredients, except the granulated white sugar. Set aside.
STEP 3: In a large bowl, cream together the butter, shortening, white sugar, and molasses, using a handheld mixer. Add the eggs and vanilla extract and continue mixing until combined.
STEP 4: Slowly add the dry ingredients, a little at a time, to the creamed mixture and continue mixing until everything is combined. Add the food coloring and blend to combine.
STEP 5: Drop spoonfuls (or use a cookie scoop) of the dough in even mounds onto your prepared cookie sheet.
STEP 6: Bake at 350° F for 10-12 minutes. When done, remove them from the oven and cool the cookies on a rack.
STEP 7: When the cookies have cooled and you’re ready to add the filling, add all of the filling ingredients to a large bowl and combine using a handheld mixer. Mix until light and fluffy.
STEP 8: Pipe on the filling, using a ziplock or piping bag, to the inner side of half of the cookies. Top each with another cookie and gently press down to create a sandwich pie.

What Kind Of Oats Should I Use?
Don’t use old-fashioned oats because they are too coarse for this recipe – you definitely want to use quick oats, instead. If you can actually pulse the quick oats in a food processor or your blender just once or twice, that’s even better. When the cookie dough bakes, you want the oat pieces to be small and integrated into the cookie, not big and visible like traditional oatmeal cookies.
Note: Quick Oats are not the same as Instant Oats. Make sure you’re using quick oats.

How Do I Add The Filling?
I like to use a piping bag or a ziplock bag. I just fill the bag and cut the corner for the Ziploc or apply a tip to the piping bag, and starting at the center of the cookie, swirl it on. Don’t pipe it out to the edges, though. When you add the top oatmeal cookie and press down, the filling will naturally squeeze out to the edges.
If you don’t want to use the piping method, use a small offset spatula or a spoon to add the filling to the center, leaving room at the edges.
Note: make sure the cookies are fully cooled before adding the filling.

Can I Use Butter Instead Of Shortening?
Technically, yes you can. The reason for the shortening, which is actually combined with butter in both the dough and the filling, is that it gives a more authentic taste and texture to the oatmeal cream pies.
That said, if you prefer to use all butter to replace the shortening in both the dough and filling, you can certainly do that. However, the cookies may spread more when baking when you use all butter.

Variations
While this recipe replicates the original Little Debbie version, you can certainly add some inclusions to the cookie dough to make it even yummier. Go classic by adding raisins. Chocolate chips or peanut butter chips are also a tasty addition. I recommend adding just a smattering to the dough so that the inclusions don’t weigh down the cookie as it bakes.

Storage
Store the Copycat Oatmeal Cream Pies in an airtight container on the countertop or in the refrigerator for up to 4 days.

Are These Oatmeal Cream Pies Freezer-Friendly?
Yes, the assembled Oatmeal Cream Pies can be stored in the freezer for up to 2 months. Wrap them tightly in plastic, individually. Defrost in the refrigerator, and then at room temperature, before serving.
