Oatmeal Cream Pies are soft oatmeal cookies with a creamy, marshmallow layer that will remind you of the classic Little Debbie snack. Try my Peanut Butter Baked Oatmeal for another baked oatmeal treat.

Oatmeal Cream Pies

If this treat sounds familiar, you are probably thinking of the Little Debbie Oatmeal Creme Pies that have been around since the 1960s. In fact, their Creme Pies were the first snack they ever made under that Little Debbie name. I remember opening those individually wrapped snacks and biting into the softest, creamiest, and yummiest treat! Now, it’s easy to make my own Oatmeal Cream Pies without any added preservatives.

Oatmeal Cream Pies Recipe

There are two parts to this recipe–the soft and chewy oatmeal cookies and the cream filling.

Cookies Ingredients (full recipe below)

  • Butter
  • Brown sugar
  • Granulated sugar
  • Eggs
  • Vanilla
  • All-purpose flour
  • Old-fashioned oats–Also known as rolled oats, this is your best bet when baking cookies and muffins since they cook in about 5 minutes. You could also get away with using quick oats, but the texture will be a bit different. Do not use instant oatmeal in this recipe.
  • Baking soda
  • Cinnamon

Filling Ingredients

  • Butter
  • Confectioners’ sugar
  • Marshmallow creme–Marshmallow creme is a spreadable and sticky marshmallow concoction. You may also see it as marshmallow Fluff in recipes, but marshmallow Fluff is actually a specific brand of marshmallow creme.
  • Whole milk

Don’t skimp on the sugars in this recipe. Have you ever noticed that the ratios of sugar in most cookie dough recipes are higher than other baked goods? That is because not all of the sugar dissolves during mixing, which is good! The dough will soften and spread while baking as more sugar dissolves ensuring the classic cookie shape and texture.

If you happen to use less sugar than the recipe calls for your final cookie could puff up more and the texture could be less chewy. In addition, recipes with brown sugar will absorb moisture after baking which helps to ensure that they stay chewy, which is perfect for this recipe.

To make the oatmeal cookies, get out your stand mixed with the paddle attachment. Cream the butter and sugars together until fluffy. Add in the eggs and vanilla, mixing until combined. With the mixer off, add the flour, oats, baking soda, and cinnamon. Mix on low until everything is combined.

Refrigerate the dough for at least 30 minutes, or up to overnight. There is no need to cover the dough if you are letting it chill for just 30 minutes. If you keep it overnight, press some plastic wrap down onto the dough to keep it covered.

How to Store Oatmeal Cream Pies

You can keep these oatmeal cream pies in an airtight container at room temperature for about two days. After a couple of days, store them in the refrigerator. You can freeze them, but I would not let them stay in the freezer for more than a month. Make sure you date and label the container and let the cream pies thaw at room temperature for about an hour.

Oatmeal Cream Pies are soft oatmeal cookies with a creamy, marshmallow layer that will remind you of the classic Little Debbie snack.



  • 1 cup (2 sticks / 227g) butter, softened
  • 1 cup (200 g) brown sugar, packed
  • ½ cup (100 g) granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla
  • cups (187.5 g) all-purpose flour
  • 3 cups (270 g) old-fashioned oats
  • 1 teaspoon baking soda
  • 2 teaspoons cinnamon


  • ¾ cup (1½ sticks / 170g) butter, softened
  • 3 cups (375 g) confectioners' sugar
  • 1 jar (7 ounces) marshmallow creme
  • 1-3 tablespoons whole milk



  • In your stand mixer fitted with a paddle attachment, add the butter and sugars. Cream for 2-3 minutes or until they are fully incorporated and fluffy.
  • Add in the eggs and vanilla and mix until combined.
  • Turn the mixer off and add in the flour, oats, baking soda, and cinnamon.
  • With the mixer on low, mix until just combined.
  • Refrigerate for 30 minutes, or up to overnight.
  • When you are ready to bake the cookies, preheat oven to 350°F and prepare a baking sheet by lining it with parchment paper.
  • Use a cookie scoop (Mine holds about 1½ tablespoons of batter) and drop dough onto the parchment-lined baking sheet about 2 inches between.
  • Bake for 8-10 minutes or until the edges are lightly golden. The top of the cookie may appear a little wet, but they will continue to bake out of the oven. You don’t want the cookies raw, so make sure they bake for at least 8 minutes.
  • After allowing the cookies to slightly cool, move them to a cooling rack.


  • While the cookies are cooling, mix together the butter, sugar, and marshmallow creme.
  • Add enough milk to make the filling spreadable.
  • Spread filling on the bottoms of half the cookies and top with the remaining cookies.
