Many families have their own signature banana bread recipe. It's one of those baked goods that gets passed down through the generations. Some have nuts, others sprinkle in chocolate chips ...
Scatter reserved raw walnuts down the center. Bake bread until risen, golden brown on top, and a tester inserted into the center comes out with a few moist crumbs attached, 50 to 60 minutes.
The best bananas for baking are ones that are so ripe, they've turned black. If freezing them, make sure you remove the skin first. I mash mine slightly before freezing in snaplock bags.
