Ingredients
  

  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 1 cup unsalted butter softened
  • 3/4 cup brown sugar
  • 1/2 cup granulated sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 3 cups old-fashioned oats
  • 1 cup raisins chocolate chips, or chopped nuts, optional

Equipment

  • 1 mixing bowl
  • 1 hand mixer or whisk
  • 1 baking sheet
  • 1 cookie scoop
  • 1 wire rack

Method
 

  1. Preheat the oven to 350°F.
  2. Line a baking sheet with parchment paper.
  3. Whisk the flour, baking soda, cinnamon, and salt together in a mixing bowl.
  4. In a separate bowl, beat the softened butter, brown sugar, and granulated sugar until creamy.
  5. Add the egg and vanilla extract, then mix until smooth.
  6. Add the dry ingredients and stir just until combined.
  7. Fold in the oats and any optional raisins, chocolate chips, or chopped nuts.
  8. Scoop the dough onto the prepared baking sheet, leaving space between each cookie.
  9. Bake for 9 to 11 minutes, or until the edges are lightly golden and the centers still look soft.
  10. Let the cookies cool on the baking sheet for 5 minutes.
  11. Transfer to a wire rack to cool completely.

Notes

Use old-fashioned oats for the best chewy texture. Do not overbake the cookies; the centers should still look slightly soft when they come out of the oven. For thicker cookies, chill the dough for 20 to 30 minutes before baking.
