Banana Oatmeal Cookies with Chocolate Chips and Walnuts

"Banana Oatmeal Cookies with Chocolate Chips and Walnuts, an easy homemade cookie recipe. These cookies turn out crispy on the outside, and soft and chewy on the inside. They have a nice subtle banana flavor and they are loaded with oats, chocolate chips, and walnuts. You can use your favorite baking chip (such as dark chocolate or white chocolate) instead of the mini chocolate chips and/or substitute your favorite nut (such as pecans) for the walnuts."
