Banana bread is named after its cheapest major ingredient. Three ripe bananas cost 66 cents, 15% of the loaf, and they are often bananas that were about to be thrown out, which makes them close to free. The cost is in the butter, $1.40, and in the walnuts, $1.10. Those two lines are 57% of a $4.39 loaf.
The walnuts are the decision. Leave them out and the loaf costs $3.29, a 27.4% food cost at $12; put them in and it is 36.6%, the difference between a comfortable bakery margin and a thin one. Nuts, chocolate chips, and streusel are the add-ins that turn a plain loaf into a premium one, and they are expensive per ounce. A nut loaf priced the same as a plain one gives the extra cost away, which is why bakers who sell both usually charge a dollar or two more for the loaded version.
Loaves are also sold whole, which makes waste lumpy. A loaf that does not sell is a whole $4.39 lost, not a slice: a market baker who brings twelve and sells nine has given back the margin on nearly two of the nine sold. Slicing a loaf or two for single sales, or freezing what is left, since banana bread freezes well, keeps the end-of-day count from deciding the week's profit.
