Think of this loaf as a smart use-up for those last two bananas on the counter and the half-bag of walnuts in your pantry—no specialty shopping required. The batter comes together in one bowl, and the bread freezes beautifully, so you can slice off a piece of cozy flavor whenever you need it.
Over-ripe bananas, mashed – 3 large (about 1 ½ cups)
Preheat the oven to 350°F 177°C
Toast the walnuts first—8 minutes at 350°F—than cool and chop; the quick pre-roast wakes up their flavor and keeps them crunchy under the streusel. For a bakery-style finish, brush the hot loaf with a tablespoon of warm maple syrup as soon as it comes out of the oven; it adds gloss and seals in moisture.
