Ingredients Method Notes

Ingredients
  

Ingredients
  • 1 cup all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup unsalted butter, softened
  • ½ cup granulated sugar
  • ½ cup brown sugar, packed
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 ½ cups old-fashioned oats
  • ½ cup raisins or chocolate chips (optional)

Method
 

Instructions
  1. Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
  2. In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy (2-3 minutes with hand mixer or 3-4 minutes by hand).
  3. Beat in the egg and vanilla extract until well combined and smooth.
  4. In a separate small bowl, whisk together the flour, baking soda, and salt, then gradually add to wet ingredients, mixing just until combined.
  5. Stir in the oats and any optional add-ins like raisins or chocolate chips.
  6. Drop rounded tablespoons of dough onto prepared baking sheets, spacing them about 2 inches apart.
  7. Bake for 10-12 minutes, or until edges are golden brown but centers still look slightly underdone.
  8. Let cookies cool on baking sheet for 5 minutes before transferring to wire rack to cool completely.

Notes

Don't overbake - cookies continue cooking on hot baking sheet. Use room temperature ingredients for better texture. Cookies freeze beautifully for up to 3 months.
