Amazingly rich and fun homemade oatmeal cream pies made from homemade cookies and marshmallow fluff filling are an easy and delish dessert!
I was shocked after making these for the first time because they were stunning. I am in love and want to make them every day of the week. Every. Day. I wasn’t sure how the filling would change the cookie as it sat overnight, so I did some playing. I baked my cookies, so some were still really soft and a little underdone, some that were done, and some that were smidgen overdone. As the cookie sits, the icing starts to soften the cookie.
They were even better the second day than the night I made them! That being said, the softest cookies were great, but those made with a hint of crunch were the best. The overdone ones were significantly resurrected from sitting overnight with the filling but were still a little crunchier than I would prefer.

Expert Tips
- These last for about 3 to 4 days stored in an airtight container in the refrigerator. Remember that they continue softening because of the frosting filling over time, so they may get softer and chewier after a couple of days. They’ll last for up to 4 months frozen in an airtight container.
- Play with the textures that you prefer best, and have fun making these cuties—and eating them, too!
- This marshmallow fluff is so yummy and works great in many other recipes, such as The Best and Easiest Fruit Dip and this Easy Chocolate Fudge Recipe.

Ingredients
For the cookies:
- 3/4 cup butter, (1 1/2 sticks, at room temperature)
- 1 1/2 cups brown sugar
- 1 large egg
- 2 teaspoons vanilla
- 1 1/2 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 2 1/4 cups old fashioned oats
For the filling:
- 1/2 cup butter, at room temperature
- 1 teaspoon vanilla
- 2 cups powdered sugar
- 6 ounces Marshmallow Cream
Instructions
Preheat the oven to 325 degrees F. and line your baking sheets with parchment paper.
Add the butter and the brown sugar to the bowl of your stand mixer and beat on medium speed until the mixture is light andfluffy, around 2 minutes.
Add the egg and vanilla and beat for another minute. Add the flour, sprinkle in the baking soda, baking powder, and salt. Mix until combined. Add the oats and combine. The mixture will be a little tacky, but you should be able to roll it into a ball in your hands without making a total mess. If it is too sticky, add 1 tablespoon of flour at a time until the mixture can be handled.
Roll the dough into 1 to 1.5-inch balls, using your hands, and place the balls on the prepared cookie sheet 2 inches apart. Bake for 10 to 14 minutes until the edges begin to brown and the centers are set. Transfer to a wire rack and let them cool completely.
For the filling, beat the butter and vanilla together until light and fluffy, about 2 minutes. Add the powdered sugar and beat for another 2 minutes. Gently fold in the marshmallow cream.
When the cookies are cooled, match them witha mateaccording tosize. Take one cookie and place a few tablespoons of the filling in the center on the flat bottom of the cookie. Take the mate and place it on top (flat sides together) and press it until the filling comes to the edge of the cookies.
Enjoy with lots of milk — they are rich!
Notes
- The cookies continue softening because of the frosting filling over time so that they may get softer and chewier after a couple of days.
- They’ll last for up to 4 months frozen in an airtight container.

- To make these gluten-free, substitute gluten-free flour and GF oats for regular and old-fashioned oats.
