  • Homemade Oatmeal Cream Pies – Chewy oatmeal cookies filled with a fluffy marshmallow cream frosting. A nostalgic childhood treat that you can easily make at home!

    Oatmeal cookies are one of my all-time favorite cookie recipes. I love to make different variations like my oatmeal chocolate chip cookies, oatmeal raisin cookies, and monster cookies.

    I’m super excited to share this new cookie recipe with you all! Oatmeal cream pies were one of my childhood favorites. I was always so excited when my mom put one in my lunch box. And when I saw this recipe in my friend Megan’s new cookbook, I couldn’t wait to make them at home. My kids were even more excited!

    I’ve always been a huge fan of oatmeal cookies. The oats make the cookies soft and chewy, while the frosting adds the perfect sweetness. The dough is AMAZING too…I may have snuck a few bites in the process. ;)

    These oatmeal cream pies taste so nostalgic and are even better than the infamous Little Debbie cream pies. Between the delicious cookie and sweet marshmallow frosting, every bite is perfection!

    How to make oatmeal cream pie cookies

    I love that these cookies are simple and delicious. It’s just a few simple steps and you can find the printable recipe below.

    Step 1: Make the oatmeal cookie dough

    Combine the butter, brown sugar and granulated sugar in a large mixing bowl. Beat on medium speed until creamy. Add in the egg and vanilla and beat until free of lumps.

    In a separate bowl, combine the flour, baking soda, baking powder, salt, cinnamon and nutmeg. Mix well. Gradually add to the butter mixture and mix just until combined. Stir in the oats until combined.

    Step 2: Scoop dough onto baking sheet

    Using a small cookie scoop or Tablespoon, drop the cookie dough onto the baking sheet about 2-inches apart. Bake in the oven at 350°F for 8-10 minutes, or until the edges are lightly golden but the center is still slightly soft.

    Remove from oven and let cool on pan for a few minutes. Then transfer to a cooling rack to cool completely.

    Step 3: Make the frosting

    In a large bowl, combine the butter, powdered sugar, marshmallow creme and vanilla. Mix with beaters until smooth and creamy. If needed, add more powdered sugar.

    Then scoop frosting into a zip top bag and snip off one of the ends. Alternatively, you could use a frosting bag and piping tip.

    Step 4: Fill the oatmeal cream pies

    To fill the oatmeal cream pies, frost the bottom of one cookie (similar to the picture below) and then place another cookie bottom on top. Repeat until all oatmeal cream pies are sandwiched together.

    Storage and freezing

    How long do oatmeal cream pies last?

    Store oatmeal cream cookies in an airtight container at room temperature for 2-3 days. If stored in the fridge, they will keep a little longer. Just make sure to let them sit out for a few minutes before enjoying.

    Can you freeze oatmeal cream pies?

    Yes, these oatmeal pie cookies can be frozen. Simply place in a freezer bag with a sheet of wax paper in between each layer. When ready to enjoy, let sit out on the counter to thaw.

    Notes

    If making cookie sandwiches, use a small cookie scoop or roll into a 1-inch ball. If serving singular cookies with frosting on top, I prefer to use a medium cookie scoop.
