For an enhanced banana flavor, use overripe bananas with brown spots. To toast the walnuts, spread them on a baking sheet and bake at 350°F (175°C) for 5-7 minutes, or until fragrant. Watch carefully to prevent burning. If you don't have mayonnaise on hand, you can substitute with an equal amount of sour cream or plain yogurt, although the flavor will change slightly. For a richer frosting, use European-style butter with a higher fat content. The cake can be stored in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.
