Ingredients:

  • 1 cup (227g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 1 cup (220g) packed light brown sugar
  • 2 large eggs
  • 1 tsp pure vanilla extract
  • 1 ½ cups (190g) all-purpose flour
  • 1 tsp baking soda
  • 1 tsp ground cinnamon
  • ½ tsp salt
  • 3 cups (240g) old-fashioned rolled oats
  • 1 cup (170g) raisins or chocolate chips (optional, your choice)

Instructions:

  1. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicon mats.
  2. In a large bowl, beat softened butter with granulated and brown sugars until fluffy and light in color (about 2-3 minutes).
  3. Mix in eggs one at a time, then add vanilla extract until fully incorporated.
  4. In a separate bowl, whisk together flour, baking soda, cinnamon, and salt.
  5. Gradually add dry ingredients to the wet mixture. Stir just until combined.
  6. Fold in the rolled oats and your choice of raisins or chocolate chips.
  7. Using a spoon or cookie scoop, place evenly sized mounds of dough (about 1.5 tablespoons) on prepared baking sheets, spaced about 2 inches apart.
  8. Bake for 10-12 minutes, or until edges are golden brown and centers still look slightly soft.
  9. Allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
