  • 1 cup (2 sticks / 227 g) unsalted butter, room temperature
  • 1 cup (200 g) light brown sugar, packed
  • ½ cup (100 g) granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • ½ teaspoon kosher salt
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • cups (187.5 g) all-purpose flour
  • 2 cups (180 g) rolled oats
  • 1 cup (168 g) milk chocolate chips
  • 1 cup (168 g) semi-sweet chocolate chips


  • Preheat oven to 350°F (175 degrees C). Prepare a 9x13-inch baking pan with baking spray, parchment, or the butter/flour method.
  • In the bowl of a stand mixer (can also use hand-held mixer) beat the butter, brown sugar, and granulated sugar until well mixed, about 3 minutes.
  • Add in eggs one at a time, mixing well after each addition.
  • With mixer on low, add in the vanilla extract.
  • Remove bowl from stand mixer and add in salt, baking soda, baking powder, flour, rolled oats, plus semi-sweet chocolate chips. Stir by hand to moisten all ingredients.
  • Spread ½ mixture into the prepared baking pan. Pour milk chocolate chips on top of mixture. Carefully press the remaining cookie mixture on top of chocolate.
  • Bake in the preheated oven until golden brown, 30 to 40 minutes. (It shouldn't jiggle too much)
  • Let cool in the pan for about 5 minutes before cutting into bars.
