I make this pumpkin banana bread when I have ripe bananas and a cup of pumpkin puree to use up and want something warm and spiced for breakfast or dessert. Mashed bananas and plain pumpkin puree make a moist, tender crumb, while brown sugar caramelizes the edges. It bakes in one loaf pan, travels well for potlucks and holiday gifting, and freezes in slices for 2 to 3 months.
