For the best flavor, use very ripe bananas – the spottier, the better! To toast the walnuts, spread them on a baking sheet and bake at 350°F (175°C) for 5-7 minutes, or until fragrant. Let cool before chopping. Don't overmix the dough, or the cookies will be tough. For a richer flavor, substitute half of the margarine with unsalted butter in the cookie dough. Store unfrosted cookies in an airtight container at room temperature for up to 3 days, or in the freezer for up to 2 months. Frosting can be stored in the refrigerator for up to a week. If you don't have walnuts, pecans or macadamia nuts are also delicious.
