Ingredients

  • 1 cup unsalted butter, softened
  • 1 cup packed brown sugar
  • ½ cup granulated sugar
  • 2 large eggs
  • 2 tsp vanilla extract
  • 1½ cups all-purpose flour
  • 1 tsp baking soda
  • ½ tsp salt
  • 1 tsp ground cinnamon
  • ½ tsp ground nutmeg, optional
  • 3 cups old-fashioned rolled oats
  • 1½ cups raisins
  • ½ cup chopped walnuts or pecans, optional

Method

  1. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
  2. In a large bowl, beat the softened butter, brown sugar, and granulated sugar until creamy.
  3. Add the eggs one at a time, beating well after each addition. Stir in the vanilla.
  4. In a separate bowl, whisk together the flour, baking soda, salt, cinnamon, and nutmeg.
  5. Gradually add the dry ingredients to the butter mixture and mix until just combined.
  6. Stir in the oats, raisins, and nuts if using.
  7. Drop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches between cookies.
  8. Bake for 10–12 minutes, until the edges are golden but the centers still look slightly soft.
  9. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack.
  10. Serve warm or completely cooled.
