Homemade Oatmeal Cream Pies

As a kid, one of my very favorite indulgences were Oatmeal Cream Pies. Something about those soft oatmeal cookies holding in that decadent marshmallow cream. I would crave this special flavor mixture time and time again! As an adult, I think its so fun to learn how to make homemade oatmeal cream pies in place of the original. To be honest, this version is even better than I remember them.

Oatmeal Cream Pie Bars

I gotta be honest…I made fun of Pat this Christmas because of all the cookies he could request, he requested oatmeal cookies. I was like EXCUSE ME?! You chose OATMEAL cookies? There are so many amazing options and you pick OATMEAL!? Well…my Mom was up to the challenge and made him the most amazing Oatmeal Cookies on the face of the Earth, and I think I ended up eating more of them than Pat did.

Once I got over that snobby attitude, I knew that I would love these delicious Homemade Oatmeal Cream Pies. I wasn’t wrong. Mom made them absolutely impeccable and I’m so excited for you to try these. An adult version of a childhood staple is always a must-try!

Oatmeal Cream Pies Serving Recommendations

I recommend cutting your homemade oatmeal cream pies while they’re frozen. Keep them in the fridge in a sealed container after that. They’re SO GOOD when served at room temperature, but they can get a little messy with all that cream. I prefer them cold and with a bit more structure. They are SO DELICIOUS either way. I am so obsessed with these oatmeal cream pie bars, it’s hard to put into words.

Who invented Oatmeal Cream Pies?

Oatmeal Cream Pies (creme) were invented by Little Debbie. It was the very first snack the company created, back in the 1960s. This sweet treat has been a classic childhood favorite ever since! These Oatmeal Cream Pie Bars are a grown-up version of the Little Debbie original. I like to think these homemade oatmeal cream pies are a bit healthier too.

Ingredients

For the Bars:

  • cups unsalted butter 2 1/2 sticks
  • ¾ cup dark brown sugar firmly packed
  • ½ cup sugar
  • 2 eggs large
  • 1 teaspoon vanilla extract
  • cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg
  • ¼ teaspoon table salt
  • ¼ teaspoon coarse sea salt
  • cups Old-Fashioned Oats uncooked
  • cups Quick Oats uncooked

For the Cream Filling:

  • ¾ cup 12 tablespoons unsalted butter
  • 2 cups powdered sugar
  • 1 jar marshmallow fluff 13 ounce
  • teaspoon vanilla extract
  • ¾ teaspoon kosher salt

Instructions

For the Bars:

  1. Heat oven to 375°F and spray two 8 x 12-inch baking pans with cooking spray (if you don't have two 8x12 pans, use one 12 x 16-inch pan, and use 1 cup less dough. Line the pan with parchment, so that each edge of the pan has a 2-inch over-flap. Spray the parchment with nonstick cooking spray.
  2. In the bowl of a stand mixer, cream the butter and sugars together until creamy. Add eggs and vanilla and beat well.
  3. In a medium bowl, whisk together the flour, baking soda, cinnamon, nutmeg and salts. Add the flour mixture to the wet mixture all-at-once and beat only until flour mixture is incorporated.
  4. Add the oats and mix until the oats are incorporated.
  5. Divide the dough in-half and spread half in each pan. Spray a wooden spoon or rubber spatula with cooking spray to prevent the dough from sticking. Work the dough evenly until it reaches across the pans evenly. (If necessary, spray your fingers with cooking spray and spread the dough with your fingers. The dough is somewhat stiff and sticky.)
  6. Bake 12-13 minutes or until the dough is cooked in the middle and is light golden brown. Do not over-bake or the bars will dry out.

While the bars are baking, make the Cream Filling:

  1. Use an electric mixer to beat the softened butter until fluffy. Add the powdered sugar and beat until lighter in color and smooth. Add marshmallow cream, vanilla and salt. Beat until light and fluffy. Set aside until ready to use.
  2. Transfer the cookie bars to a cooling rack to cool 10 minutes. Lift the bars out of the pans, by the parchment paper and set them back on the cooling rack to completely cool.
  3. When bars are cool, spread the Cream Filling over one of the uncut 8 x 12-inch cookies. Remove the parchment paper and place the other 8 x 12-inch cookie over the Cream Filling and press gently down. Place the entire large cookie on a larger baking tray and cover it with plastic wrap and foil. The cookies are easy to cut when frozen. Place in the freezer at least 2 hours or overnight.
  4. Cut the frozen cookie into bars.
  5. Enjoy!

Recipe Notes

Note - Keep the in an airtight container in the fridge. The bars will keep up to 4 days, but I doubt they last that long.
