Ingredients Method Notes

Ingredients
  

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

Method
 

Instructions
  1. Prepare your ingredients by bringing butter to room temperature, measuring all ingredients, and preheating oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. Cream butter and sugars in a large mixing bowl until light and fluffy (2-3 minutes with electric mixer).
  3. Beat in eggs one at a time, ensuring each is fully incorporated before adding the next. Mix in vanilla extract until smooth.
  4. In a separate bowl, whisk together flour, baking soda, cinnamon, and salt for even distribution.
  5. Gradually add dry ingredients to wet mixture, mixing on low speed until just combined (avoid overmixing).
  6. Stir in old-fashioned oats until evenly distributed. Fold in raisins, chocolate chips, or other mix-ins if using.
  7. Scoop rounded balls of dough (about 2 tablespoons each) onto prepared baking sheets, leaving 2 inches between cookies. Bake for 10-12 minutes until edges are golden brown but centers look slightly underdone.
  8. Cool cookies on baking sheet for 5 minutes before transferring to wire rack to cool completely.

Notes

Use old-fashioned oats for perfect texture, don't overbake (remove when edges are set but centers look soft), chill dough for thicker cookies, measure flour correctly by spooning and leveling, brown sugar is key for moisture and chewiness.
