Soft and chewy oatmeal cookies are sandwiched together with delicious vanilla buttercream to create the perfect dessert. Forget Little Debbie, fresh, homemade Oatmeal Cream Pies are where it’s at.
Preheat oven to 350°F. Line cookie sheets with parchment paper.
In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with an electric mixer, cream together butter and sugars until light and fluffy, about 3 minutes. Add in eggs and vanilla and mix until combined.
In a medium bowl, whisk together the flour, baking soda, cinnamon and salt. Slowly add the flour mixture to the wet ingredients, mixing until just combined. Add in oats and mix until incorporated.
To make large cookies, use a large cookie scoop (about 3 tablespoons) to drop dough onto prepared cookie sheets. Bake in preheated oven for 13-15 minutes or until golden brown. Allow cookies to sit on cookie sheets for about 5 minutes before removing them to a wire rack to cool completely. To makes small cookies, use a medium cookie scoop (about 1.5 tablespoons) of dough per cookie and bake for 10-12 minutes. Once cookies have cooled completely, prepare the cream filling.
In the bowl of a stand mixer fitted with the paddle attachment, beat butter on medium-high speed for about 5 minutes. This process will lighten the color of the butter and ensure you buttercream in extra fluffy.
