Ingredients

  • 1 ¼ cup unsalted butter, room temperature (2 ½ sticks)
  • ¾ cup firmly packed brown sugar
  • ½ cup granulated sugar
  • 1 egg, room temperature
  • 1 teaspoon vanilla
  • 1 ½ cup all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 teaspoon cinnamon
  • 3 cup old-fashioned rolled oats , uncooked
  • 1 ½ cup semi-sweet chocolate chips

Instructions

  • Heat oven to 375 degrees.
  • Beat together butter and sugars until light and fluffy using a hand or stand mixer. Beat in egg and vanilla.
  • Combine flour, baking soda, salt and cinnamon and add to the butter mixture, mixing well. Stir in the oats and chocolate chips.
  • Press dough into the bottom of a 9x13 prepared baking pan, making sure to press firmly.
  • Bake for 20 minutes or until the crust is golden brown.
  • Cool completely in the pan set on a wire wrack. Cut into squares.

Notes

Tips:
    • Make sure your butter is at room temperature before beginning the recipe. Softened butter will mix more easily with the other ingredients, resulting in a smoother dough.
    • Don't over-mix. Over-mixing the dough can result in tough bars. Mix the ingredients until just combined for the best texture.
    • Allow the bars to cool completely in the pan before slicing. This will help them hold their shape and prevent them from falling apart.
Additional Ingredient Ideas:
    • Pecans, walnuts, or macadamia nuts.
    • Dark chocolate chips, milk chocolate chips, chocolate chunks, or white chocolate chips.
    • Sweetened coconut.
    • Sprinkle flaky sea salt on the cookie bars after baking.
To Store:
Store the bars in an airtight container at room temperature for 3-4 days. You can freeze the bars for up to 3 months and thaw them at room temperature before serving.
