Chewy oatmeal cookies filled with a fluffy marshmallow cream frosting. These homemade oatmeal cream pies are a nostalgic childhood treat that you can easily make at home!
Oatmeal Cookies with Frosting
IOatmeal 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. 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 famous 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 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
- 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.
- To freeze, 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.
