Ingredients

• 1 cup (2 sticks) unsalted butter, at room temperature
• 3/4 cup packed light brown sugar
• 1 egg
• 1 teaspoon vanilla extract
• 2 1/2 cups quick-cooking (not instant) oats
• 2 1/4 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon salt
• 3/4 teaspoon ground cinnamon
• 1/4 teaspoon ground nutmeg
• 1 cup dark raisins
• 1/2 cup chopped walnuts or pecans, preferably toasted (optional)

Instructions

1. Preheat oven to 325 degrees F. Lightly grease or spray cookie sheets.
2. Cream butter and sugar on medium speed until light. Add egg and vanilla. Whisk together flour, baking soda, salt, cinnamon and nutmeg, then stir into batter. Stir in oats, raisins, and nuts. Dough will be stiff.
3. Drop dough by tablespoonfuls onto cookie sheets, using a second spoon to help shape cookies.
4. Bake in the center of the oven for 15 minutes, or until cookies are firm on top and golden on the bottom. Let cookies stand on the cookie sheets for 1 to 2 minutes, then remove to a wire rack to cool.
