Children of the 90’s, this one is for you. If the words “oatmeal cream pies” don’t stop you right in your tracks, you didn’t get enough processed food as a kid. For me, treats like these sandwich cookies take me back to the lunchbox days– back to the time when square pizza and mini cartons of chocolate milk reigned supreme. You know- those few minutes of school when you’d do anything to trade your boring PB&J for a Lunchable. If you’re salivating just thinking about it, keep reading. Today, we’re going back in time with these oatmeal sandwich cookies!
Disclaimer: not one part of me actually wants to go back to middle school. I wish I had a photo (Thank God that I don’t) so you could see me in all my prepubescent glory; maybe then you’d know why me and middle school didn’t get along. I was all limbs, braces, and eyebrows, and every inch of me, from my sun-bleached frizz to my neon green toenails, smelling like an explosion of Bath & Bodyworks products. To say it wasn’t pretty is putting it mild. Things were rough.
Although my children are young, I’ve reached the age where a few of my friends have kids who are entering this phase of life. Some of them, probably the ones who rule their classes with their athleticism and good skin, make it look easy. Others remind me of younger me: insecure, uncoordinated, and in desperate need of some dry shampoo. I don’t envy any of them for a second, but every once in a while, I’m reminded of the good things those middle school days included. And no, I’m not talking about a killer metabolism or free time out the ring yang- I’m talking oatmeal cream pies.
Oatmeal Cream Pies
Surely you remember these. Soft, chewy cookies? A sweet and slightly fluffy marshmallow filling? The sticky, comforting combination of the two, every bite better than the last? Oatmeal cream pies have long been one of my favorite processed snacks (and trust me, that’s a lengthy and detailed list), but I have never ever made them on my own. You might remember that a while back we made oatmeal cream pie ice cream sandwiches (seriously, so good), but this recipe is as new to me as it is to you. You’re welcome.
To make these oatmeal cream pies, we start with the cookies. Oats, butter, brown sugar, and molasses come together with eggs, vanilla, and the dry ingredients. These cookies spread a bit in the oven, so we opt for smaller rounds of dough. After a quick bake, we can start on the filling. Butter, sugar, and good, old fashioned marshmallow fluff round out the ingredients for the filling which gets piped or spread in between two cookies. I like to let them set for just a bit to soften the cookies, as the filling seeps in a barely softens each bite. Double you’re welcome.
Give these oatmeal cream pies a try and let me know what you think. While we can’t (and probably shouldn’t?) eat all the same things we did when we were kids, there’s not a thing wrong with a little kitchen reminiscing. This round of memory lane is one me. Happy Friday and Happy Baking, y’all!

- Prep Time: 15
- Cook Time: 15
- Total Time: 30 minutes
- Yield: 18 Cookies
- Category: Dessert
Ingredients
For the Cookies:
- ½ cup unsalted butter, at room temperature
- 3/4 cup brown sugar
- 1 large egg
- 1 tablespoon molasses (optional)
- 1 teaspoon vanilla extract
- 3/4 cup all-purpose flour
- ½ teaspoon baking soda
- 1/4 teaspoon cinnamon
- ½ teaspoon salt
- 1 cup quick cooking oats
For the filling:
- ½ cup unsalted butter
- 1 cup powdered sugar
- 7 ounces marshmallow fluff
Instructions
To prepare the cookies:
- Preheat the oven to 350 degrees Fahrenheit and line 2 sheet pans with parchment paper.
- In a large bowl or the bowl of a stand mixer, cream the butter and brown sugar until smooth and combined, about 1-2 minutes. Add the egg, molasses, and vanilla and stir to combined. Scrape the sides of the bowl and add the remaining ingredients. Stir on low just until well-combined.
- Use a small cookie scoop to spoon 2 teaspoon sized rounds of dough 2” apart on the prepared cookie sheets. Bake one at a time in the preheated for about 9 minutes or until the edges are set and turning golden. The center of the cookie may still look wet. Remove from oven and allow to cool completely. If you notice your cookies look wonky upon removal from the oven, use the rim of a large glass or jar to nudge them into a rounder, perfected shape. Be sure to do this carefully while they are still fresh from the oven. Continue baking the remaining cookies and allow to cool completely.
To prepare the filling:
- Cream the butter and powdered sugar together on medium speed in a large bowl using a hand mixer. Add the marshmallow fluff and stir until well combined. If needed, you can thin the frosting out slightly with a teaspoon or two of water- be careful not to add to much though as this makes for a messy cookie. Spoon the filling into a piping bag fitted with a medium round tip and sandwich the cream in between two cookies of the same size. Alternatively, you can just spread large dollops on with a knife. Enjoy!
