Ingredients:

  • 1 cup (225g) unsalted butter, softened
  • 3/4 cup (150g) brown sugar, packed
  • 1/2 cup (100g) granulated white sugar
  • 2 large eggs, room temperature
  • 1 tsp (5ml) pure vanilla extract
  • 1 1/2 cups (190g) all-purpose flour
  • 1 tsp (5g) ground cinnamon
  • 1/2 tsp (3g) baking soda
  • 1/2 tsp (3g) salt
  • 3 cups (270g) old-fashioned rolled oats
  • 1 cup (150g) Granny Smith apple, peeled and finely diced
  • 3/4 cup (110g) raisins, plumped in warm water and drained
  • 1/2 cup (50g) chopped walnuts

Instructions:

  1. Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.
  2. Dice the Granny Smith apples into uniform 1/4-inch cubes and pat them thoroughly with paper towels to remove excess surface moisture.
  3. In a medium bowl, cream together the softened unsalted butter, brown sugar, and granulated white sugar using an electric mixer until light and fluffy.
  4. Beat in the eggs one at a time, then stir in the pure vanilla extract.
  5. In a separate large bowl, whisk together the all-purpose flour, ground cinnamon, baking soda, and salt.
  6. Gradually add the dry flour mixture to the wet creamed butter mixture, mixing on low speed until just combined.
  7. Fold in the old-fashioned rolled oats, diced apples, drained raisins, and chopped walnuts by hand.
  8. Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them 2 inches apart.
  9. Bake for 12-15 minutes or until the edges are golden brown.
  10. Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire cooling rack.
