  • 3⁄4 cup butter, softened, divided
  • 1 cup chunky peanut butter, divided
  • 1⁄2 cup brown sugar
  • 1⁄4 cup sugar
  • 1 large egg
  • 1 tsp. vanilla
  • 1 3⁄4 cups all-purpose flour
  • 1⁄4 cup ground oatmeal
  • 1⁄4 tsp. salt
  • 2 1⁄2 cups powdered sugar
  • 2 Tbsp. milk


  • Preheat oven to 350°F. Line 2 baking sheets with parchment paper.
  • In large bowl, combine 1⁄2 cup butter, 3⁄4 cup peanut butter, brown sugar, and sugar and beat until smooth. Stir in egg and vanilla until combined. Then add flour, ground oatmeal, and salt. Roll tablespoon-size scoops of dough into balls and place on prepared baking sheets 2 inches apart. Using the bottom of a glass, gently press cookie dough to 1⁄2 inch.
  • Bake for 10 minutes, or until cookies are golden and set. Cool cookies completely on a wire rack.
  • Meanwhile, in medium bowl, combine 1⁄4 cup butter, 1⁄4 cup peanut butter, and 1 cup powdered sugar; beat well. Alternately add remaining powdered sugar with enough milk to form a creamy filling.
  • Spread about a teaspoon of filling onto the bottoms of 1⁄4 of the cookies. Top with the remaining cookies. Let stand until set; store covered at room temperature.
