I love mixing different ingredients into these oatmeal cookies to change it up. Keep in mind that you don’t want to add too much without decreasing the raisins or chocolate chips, or the cookies will be dry. Try crushed nuts, such as walnuts, pecans, peanuts, or cashews, or seeds such as pumpkin seeds, chia seeds, hemp seeds, or flaxseed. You can also use other dried fruit such as dried cranberries or dried blueberries instead of raisins.
