Gluten Free Oatmeal Cream Pie Cookies are the ultimate childhood favorite dessert. They're filled with a delicious vanilla buttercream frosting that pairs perfectly with the thin and chewy oatmeal cookies.

Ingredients
 

oatmeal cookies

  • 1/2 cup salted butter, melted
  • 1/2 cup dark brown sugar, packed
  • 1/4 cup granulated sugar
  • 1 large egg
  • 2 tsp vanilla extract
  • 3/4 cup gluten free flour
  • 1/2 tsp baking soda
  • 1 tsp ground cinnamon
  • 1 1/2 cup rolled oats

vanilla buttercream filling

  • 1/2 cup salted butter, room temperature
  • 2 1/2 cups powdered sugar
  • 1 tbsp vanilla extract
  • 2 tbsp half and half

Instructions
 

  • Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper and grease with nonstick.
  • Add the butter, dark brown sugar, granulated sugar, egg and vanilla extract to a large mixing bowl
  • Using a hand mixer or whisk, mix until fully combined
  • Fold in the gluten free flour, baking soda, ground cinnamon and rolled oats until just combined. You don't want to overmix!
  • Using a 1 inch cookie scooper to evenly place the cookie dough on the baking sheet at least 2 inches apart.
  • Bake the cookies for 10-12 minutes, until the edges are golden brown.
  • You will have to bake multiple trays of cookies and that is okay! Continue to scoop and bake until all of the batter is used.
  • After the cookies are done baking, it's time for them to cool and we will work on the vanilla buttercream frosting.
  • To a medium/large mixing bowl add the butter, powdered sugar, vanilla extract and half & half
  • Use an electric hand mixer and mix until fully combined
  • Once the cookies are cooled, it's time to fill our cookies!
  • Use a piping bag if possible and pipe on one side of each cookie.
  • However, if you don't have piping bags, measure about 1/4 cup of frosting on one side of the cookie. You may need to spread it out to the edges using a knife or spoon.
  • Once you've added the buttercream to half of your cookies, it's time to sandwich them together. Add another cookie on top of each, pressing down softly.
  • Enjoy!
