  • 2 1/4 cups Old-fashioned oats, divided
  • 2 cups All-purpose flour
  • 1 tsp Baking soda
  • 1 tsp Baking powder
  • 1 tsp Kosher salt
  • 1 cup Unsalted butter, softened
  • 1 cup Dark brown sugar, firmly packed
  • 1/2 cup Granulated sugar
  • 1 cup Creamy peanut butter
  • 2 large Eggs, room temperature
  • 2 tsp Vanilla extract
  • 10 oz Bittersweet chocolate chips, divided (or semi-sweet)


  • Preheat the oven to 350 degrees F.
  • Line a 9×13 metal baking dish with parchment paper, leaving extra overhang on the sides to use as a sling after baking.
  • In a medium-size bowl whisk together 2 cups old-fashioned oats, all-purpose flour, baking soda, baking powder, and salt. Set aside.
  • In a large bowl beat the softened butter with the dark brown sugar and granulated sugar at medium speed until creamy and fluffy, about 3 to 5 minutes.
  • Add the creamy peanut butter and beat until combined.
  • Add the eggs and vanilla extract beating until combined.
  • Gradually add the flour mixture to the butter mixture, beating until just combined.
  • Stir in 8 ounces of the chocolate chips. Reserving 2 ounces for the top.
  • Spread the cookie dough evenly in the prepared baking dish. Sprinkle the top with the remaining 1/4 cup of oats and the remaining 2 ounces of chocolate chips.
  • Bake for 25 to 30 minutes until golden brown on the edges.
  • Place on a wire rack to cool completely. At least 2 hours up to overnight. I like to leave them until the chocolate chips set up. Using the parchment handles lift the bars out of the pan to a cutting board. Cut into 24 bars and serve.
