Ingredients:

  • 1/2 cup (113g) unsalted butter, softened
  • 1/2 cup (100g) granulated sugar
  • 1/2 cup (100g) packed light brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract (5ml)
  • 3/4 cup (90g) all-purpose flour
  • 1/2 teaspoon baking soda (2.5ml)
  • 1/2 teaspoon ground cinnamon (2.5ml)
  • 1/4 teaspoon salt (1.25ml)
  • 1 1/2 cups (135g) rolled oats (not instant)

Instructions:

  1. Preheat oven to 375°F (190°C). Line baking sheets with parchment paper or silicone mats.
  2. In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
  3. Beat in the egg and vanilla extract until well combined.
  4. In a separate bowl, whisk together the flour, baking soda, cinnamon, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  6. Stir in the rolled oats until evenly distributed.
  7. Drop by rounded tablespoons (or use a cookie scoop) onto the prepared baking sheets, leaving space between each cookie.
  8. Bake for 10-12 minutes, or until the edges are golden brown and the centers are set.
  9. Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
