Equipment

Ingredients

  • 1 cup unsalted butter (softened)
  • 1 cup light brown sugar (packed)
  • ½ cup granulated sugar
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 1 teaspoon salt
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1½ cups all-purpose flour
  • 2½ cups old-fashioned oats
  • 1 cup semi-sweet chocolate chips
  • 1 cup butterscotch chips

Instructions

  • Preheat your oven to 350 degrees. Use the convection bake function if you have it.
  • Using a hand mixer or a stand mixer fitted with the paddle attachment, cream the softened butter, brown sugar and granulated sugar until smooth. Scrape down the bowl once complete.
  • Next, add the vanilla extract, eggs, salt, baking soda and baking powder. Mix until combined, then scrape down the bowl again.
  • Add the flour and oats in 2-3 portions, mixing after each addition.
  • Add the chocolate and butterscotch chips and mixing until combined. Then scrape down the bowl.
  • Line a 9x13" baking pan with parchment paper and press the oatmeal cookie dough evenly throughout the pan. I like to use another sheet of parchment paper to press the dough throughout the pan since the dough is sticky.
  • Sprinkle additional chocolate and butterscotch chips over the top of the dough, if desired, then bake for 25-30 minutes or until the edges of the bars look crispy and the middle is not very jiggly (a little movement in the middle is OK).
  • Remove them from the oven and allow them to cool to room temperature before removing the bars from the pan.
