How to Make Oatmeal Cream Pies

These delicious oatmeal cream pies are so easy to make that you’ll have them on regular rotation in your cookie jar.

  1. Cream together the wet ingredients: Beat butter, shortening and sugar together until light and fluffy, then add eggs, molasses and vanilla.
  2. Mix together dry ingredients: In a separate bowl combine flour, baking soda, cinnamon and salt. Add the dry ingredients to the butter mixture, then stir in the quick oats.
  1. Bake: Roll the dough into 1.5 tablespoon sized balls or use a cookie scoop and place on cookie sheets with parchment paper. Bake for 8-10 minutes and then allow cookies to cool on a wire rack.
  2. Make the cream filling: Combine Marshmallow Fluff, vegetable shortening, powdered sugar and vanilla extract in a large bowl and beat until light and fluffy.
  3. Assemble the pies: Pipe or spread the cream on the bottom side of one cookie, and top with a second to form a sandwich.

Tips For Success

  • Don’t skip the shortening – Using only butter will cause these cookies to spread too thin.
  • Don’t overbake the cookies – Pull them out of the oven as soon as the edges are set.
  • Use a piping bag to fill the cookies. While you can technically spread the marshmallow creme on the cookies, I find it easier to pipe the filling. You can use a piping bag or a zip-top bag with the corner cut off.
  • Allow the cookies to cool completely before adding the filling. The oatmeal cookies should be at room temperature before adding the creme center. Otherwise, the creme will melt and the cookies will lose their structure.

Recipe FAQs

The center of the cookies still look wet after 10 minutes. Should I cook longer?

Not to worry! The centers will look as if they are not done, but they will continue to cook as they rest on the pan. This will ensure the softest cookie possible.

What can I use in place of Marshmallow Fluff?

We realize there are some parts of this country where you can’t easily find Fluff. We feel your pain. You can fill the cookies with vanilla buttercream frosting instead of making the Marshmallow Filling if you prefer.

I don’t have quick oats, can I use old-fashioned oats?

You can use rolled oats but pulse them in a food processor to break them up before using.

Storage & Freezing

  • In the fridge. These cookies will stay fresh for up to 2 days in the fridge. Be sure to store in an airtight container.
  • In the freezer. You can also freeze these oatmeal creme cookies for up to 2 months in a freezer bag or container. Allow them to thaw overnight in the fridge then enjoy.

Serving Size 15


For the cookies

  • ½ cup (113 g) unsalted butter, softened to room temperature
  • ½ cup (92 g) vegetable shortening, at room temperature
  • 1 cup (210 g) light brown sugar, packed
  • 2 large eggs, at room temperature
  • 2 tablespoons unsulphured molasses
  • 1 teaspoon vanilla extract
  • 1 ½ cups (195 g) all-purpose flour
  • 1 teaspoon baking soda
  • 1 ½ teaspoons ground cinnamon
  • ½ teaspoon salt
  • 3 cups (267 g) quick-cooking oats

For the cream filling

  • 7 ounces (198 g) marshmallow fluff
  • ½ cup (92 g) vegetable shortening, at room temperature
  • ½ cup (60 g) confectioners' sugar
  • 1 teaspoon vanilla extract


Make the cookies

  • Preheat the oven to 375ºF. Line a baking sheet with a silicone mat or parchment paper. Set aside.
  • In a large mixing bowl, beat together the butter and shortening with an electric mixer until well blended. Add the sugar, beat until fluffy. Add the eggs one at a time, beat well after each addition. Beat in the molasses and vanilla.
  • In a separate bowl, combine the flour, baking soda, cinnamon, and salt. Stir with a whisk. Add the flour mixture to the butter mixture, beat on low speed just until combined. With a silicone whisk, gently stir in the oats.
  • Roll the dough out into 1.5 tablespoon sized balls. Place the dough balls 2 inches apart on the prepared pan. Bake for 8 to 10 minutes. Allow the cookies to cool on the pan for 5 minutes; transfer to a wire rack to cool completely.

Make the cream filling

  • Combine all the ingredients in a bowl and beat with an electric mixer on medium speed until blended and fluffy. If the filling is too runny, add more confectioners' sugar, one tablespoon at a time until thick enough to pipe onto cookies.
  • Pipe or spread the cream over the bottom side of one cookie, top with a second cookie to form a sandwich.



  • Butter and shortening: Both are required for this recipe. Using only butter will cause the cookies to spread too thin.
  • Molasses: I love the warmth it offers but if you wish not to use it, simply omit it.
  • Quick-cooking oats: Don’t try to substitute old-fashioned oats for quick oats. It won’t work. However, if you only have old-fashioned oats on hand, you can pulse them in the food processor to break them down before using.
  • The filling: You may fill the cookies with basic vanilla buttercream instead of the marshmallow filling.
Make ahead tip

    We make these all the time they are great even if your just making oatmeal cookies

  2. Anyone else finding that the filling doesn’t whip. It turned out to be more of a glaze than anything.

    1. Jen Sobjack says:

      It’s strange that your filling was the consistency of a glaze. There is only 1 tablespoon of water and no other liquid ingredients other than 1 teaspoon of vanilla. Make sure you’re not using any more water than the recipe calls for. And you should be using vegetable shortening that isn’t melted. It must be in its solid form at room temperature.
