Oatmeal Sandwich Cookies with Vanilla Buttercream
 
Do you remember opening up those crinkly plastic wrappers and getting hit with the sweet, oat-y smell of pillowy soft cookies and sugary frosting? Well, these are all that and more. For the ultimate nostalgic treat, we sandwiched our classic Oatmeal Cookies with a creamy vanilla buttercream. The cookies are slightly crisp on the outside and perfectly chewy on the inside, making them perfect for sandwiching together with a generous slathering of vanilla buttercream.
Makes about 22 sandwich cookies
Ingredients
  • 1 cup (227 grams) unsalted butter, softened
  • 1 teaspoon (6 grams) vanilla bean paste
  • ¼ teaspoon kosher salt
  • 4 cups (480 grams) confectioners’ sugar, divided
  • 1 tablespoon (15 grams) whole milk
  • Oatmeal Cookies (recipe precedes)
Instructions
  1. In the bowl of a stand mixer fitted with the paddle attachment, beat butter, vanilla bean paste, and salt at medium speed until smooth and well combined. Reduce mixer speed to low; gradually add 2 cups (240 grams) confectioners’ sugar, beating until smooth. Beat in milk until combined; scrape sides of bowl. Add remaining 2 cups (240 grams) confectioners’ sugar, and beat until smooth and well combined. Place in a pastry bag fitted with a ½-inch piping tip. Pipe buttercream onto flat side of half of Oatmeal Cookies. Place remaining Oatmeal Cookies, flat side down, on top of buttercream.
