Ingredients:

  • 1 cup (2 sticks; 227g) unsalted butter, softened
  • ¾ cup (150g) packed light brown sugar
  • ¾ cup (150g) granulated sugar
  • 2 large eggs
  • 2 teaspoons pure vanilla extract (10ml)
  • 1 ½ cups (192g) all-purpose flour
  • 1 teaspoon baking soda (5g)
  • 1 teaspoon ground cinnamon (5g)
  • ½ teaspoon salt (2.5g)
  • 3 cups (240g) old-fashioned rolled oats
  • 1 ½ cups (255g) semi-sweet chocolate chips

Instructions:

  1. In a large bowl or stand mixer, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
  2. Beat in the eggs one at a time, then stir in the vanilla extract.
  3. In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt.
  4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix!
  5. Fold in the rolled oats and chocolate chips until evenly distributed.
  6. Cover the dough and refrigerate for at least 30 minutes. This is important to prevent spreading and develop flavor.
  7. Preheat the oven to 375°F (190°C). Line baking sheets with parchment paper or silicone baking mats.
  8. Scoop rounded tablespoons of dough onto the prepared baking sheets, leaving some space between each cookie.
  9. Bake for 10-12 minutes, or until the edges are golden brown and the centers are set.
  10. Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
