Ingredients
- 2½ cups rolled oats (or old-fashioned)
- 1¾ cups all-purpose flour
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 1 cup unsalted butter, softened but still slightly firm
- 1 cup dark brown sugar
- 1 cup granulated sugar
- 2 eggs
- 1 teaspoon vanilla extract
- 1 pound semisweet chocolate chips, divided
- ¼ pound white chocolate chips, chopped
- ½ cup walnuts or pecans
Preparation
Process oats in a food processor until very finely ground, about 2–3 minutes. Add ground oats to a large mixing bowl along with flour, baking soda, baking powder and salt. Whisk together 20 seconds then set aside.
In an electric mixer with paddle attachment, cream together butter and both sugars until well combined. Beat in eggs 1 at a time, then blend in vanilla. With mixer on low speed, slowly add dry ingredients and mix until nearly combined. Mix in most of the chocolate chips, the chopped white chocolate chips and nuts, setting aside some chocolate chips to press into tops of dough for looks.
Preheat oven to 375°. Scoop out dough, place on lightly greased cookie sheet and flatten slightly. Bake until done in the center—about 10–12 minutes for smaller cookies, 15–16 minutes for larger deli-style cookies.
