Ingredients:

  • 1 cup (226g) unsalted butter, softened
  • ¾ cup (150g) granulated sugar
  • ¾ cup (150g) packed light brown sugar
  • 2 large eggs
  • 1 teaspoon (5ml) vanilla extract
  • 1 ½ cups (192g) all-purpose flour
  • 1 teaspoon (5g) baking soda
  • 1 teaspoon (3g) ground cinnamon
  • ½ teaspoon (3g) salt
  • 3 cups (270g) rolled oats (not instant)
  • 1 cup (170g) raisins (optional)
  • 1 cup (170g) chocolate chips (optional)
  • ½ cup (50g) chopped walnuts or pecans (optional)

Instructions:

  1. In a large bowl, cream together the softened butter, granulated sugar, and brown 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. Be careful not to overmix!
  5. Stir in the rolled oats and your choice of optional add-ins (raisins, chocolate chips, nuts, etc.).
  6. Cover the dough and chill in the refrigerator for at least 30 minutes. This helps prevent the cookies from spreading too much during baking.
  7. Preheat oven to 375°F (190°C). Line baking sheets with parchment paper or silicone baking mats.
  8. Drop rounded tablespoons of dough onto the prepared baking sheets, leaving 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.
