Peanut Butter Cookie Base:

  • ½ cup unsalted butter cut into cubes
  • ½ cup creamy peanut butter
  • ½ cup granulated sugar
  • ¼ cup brown sugar
  • 1 large egg
  • 1 large egg yolk
  • 1 cup all purpose flour
  • pinch salt


  • 1 cup semisweet or bittersweet chocolate chips
  • ¾ cup peanut butter chips
  • 1 cup chopped peanut butter cups
  • ½ cup chopped salted peanuts make sure they're salted
  • ¾ cup sweetened condensed milk


  • Preheat oven to 350°F. Line a 9x13 baking dish with foil (for easy removal), and grease the foil.
  • Place the butter and peanut butter in a large bowl and microwave until melted. Whisk in granulated and brown sugars. Add egg and egg yolk, whisking until combined. Add flour and a pinch of salt and stir with a spoon or rubber spatula until combined. Pour the batter into the prepared pan and smooth the top. Bake for 10 minutes.
  • Remove the pan from the oven (the batter will be barely set but not cooked through).  Immediately top with most of the chocolate chips, peanut butter chips, peanut butter cups and peanuts (reserving a couple tablespoons of each). Pour the sweetened condensed milk evenly over the top. Sprinkle over the reserved chips, peanut butter cups and peanuts. Bake for 20-25 minutes. Allow to cool completely before cutting.
