Ingredients Method Notes

Ingredients
  

Ingredients
  • 1 cup all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup unsalted butter, softened
  • 1/2 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 1/2 cups old-fashioned oats
  • 1/2 cup raisins or chocolate chips (optional)

Method
 

Instructions
  1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
  2. In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. This should take about 2 minutes with an electric mixer or 3-4 minutes by hand.
  3. Beat in the egg and vanilla extract until well combined. The mixture should be smooth and creamy.
  4. In the same bowl, add the flour, baking soda, and salt. Mix until just combined - be careful not to overmix.
  5. Stir in the oats and any optional add-ins like raisins or chocolate chips. The dough will be thick but should come together easily.
  6. Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart. You can gently flatten them slightly if you prefer thinner cookies.
  7. Bake for 10-12 minutes, or until the edges are golden brown but the centers still look slightly soft. They will continue to set as they cool.
  8. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Notes

Use softened butter (not melted) for best texture. Don't overbake - cookies will look slightly underdone but continue cooking on the hot baking sheet. Store in airtight container for up to 5 days or freeze for 3 months.
