The nuts generally used in cookie recipe include pecan nuts, almonds, walnuts, peanuts (shelled), macadamia nuts etcetera. Nut cookies mostly use plain flour as the nuts in the recipe already add a lot of crunch to the cookie. However, those who like crispy cookies can also use wheat flour and rolled oats.
