Servings: 8


  • 1 cup unsalted butter softened
  • cups packed light brown sugar
  • 1 egg
  • 2 teaspoons vanilla extract
  • cups all-purpose flour
  • teaspoons baking powder
  • ½ teaspoon salt
  • cup old fashioned oats divided
  • 2 tablespoons milk any kind (I used 2%)
  • ¾ cup creamy peanut butter
  • ½ cup semi-sweet chocolate chips
  • Vanilla ice cream for topping if desired


  • Preheat oven to 325°F. Lightly grease a 10-inch cast iron skillet with non-stick cooking spray. Set aside.
  • In a large bowl, cream butter and brown sugar with an electric hand mixer or stand mixer with fitted paddle attached until smooth and fluffy, about 3-4 minutes. Add egg and vanilla. Beat until combined.
  • In a small bowl, whisk flower, baking powder, and salt. Gradually add flour mixture to butter mixture, beating until just combined. Beat in 3/4 cup oats and milk.
  • With dampened hands, spread half of dough mixture onto bottom of prepared skillet. Spread peanut butter onto dough, followed by chocolate chips.
  • Drop heaping spoonfuls of remaining dough over peanut butter mixture. Sprinkle with remaining 1/2 cups oat and more chocolate chips, if desired.
  • Bake until center is slightly firm and cookie is golden brown, about 45-50 minutes. Cover loosely with foil the last 10 minutes of baking to prevent excess browning, if desired. Let cool for 15 minutes, then serve with vanilla ice cream, if desired.
