Peanut Butter-Oatmeal Cookie Sandwiches With Nutella Buttercream

• FOR THE COOKIES:
• 1 cup Flour
• 1/2 teaspoons Baking Soda
• 1/4 teaspoons Baking Powder
• 1/2 teaspoons Salt
• 1 stick Butter, Softened
• 1/2 cups Peanut Butter Creamy Or Crunchy
• 1/2 cups Granulated Sugar
• 1/2 cups Light Brown Sugar, Packed
• 1 teaspoon Vanilla Extract
• 1 whole Egg
• 1 cup Quick Cooking Oats
• FOR THE FILLING:
• 1 stick Butter, Softened
• 1/2 cups Nutella (or Other Chocolate-hazelnut Spread)
• 1 cup Powdered Sugar
• 2 Tablespoons Milk

1. Preheat the oven to 350u0b0F. Combine the flour, baking soda, baking powder, and salt in a large bowl; set aside.
2. In the bowl of a stand mixer, cream the butter, peanut butter, white sugar, brown sugar, and vanilla until creamy and well-blended. Add the egg and mix until incorporated. Scrape down the sides of the bowl as needed.
3. Add the dry ingredients to the creamed mixture in a couple of batches and mix until fully incorporated. Stir in the oatmeal and drop by rounded teaspoonfuls onto a baking sheet lined with parchment paper. Gently flatten each cookie with a spatula to form 1/4 inch thick cookies and bake 9-10 minutes, or until cookies are a lightly browned. Cool on a wire rack and cool completely before filling.
4. For the buttercream filling, mix the butter and Nutella in the bowl of a stand mixer until combined. Add the powdered sugar, a little at a time and mix completely after each addition. After 1 cup of powdered sugar has been incorporated, add 1 tablespoon milk and mix well. At this point, add more powdered sugar if the consistency is too thin and more milk if the buttercream is too thick. I chose to pipe the buttercream onto the cookies. First, because I'm obsessed with piping; second, because I love the Wilton 1M tip; third, because it seemed to me like the least-messy way to actually assemble the cookies. I'm a mess in the kitchen!
