This is my historical thinking concept to provide in your post and this is my contribution @adsactly.
And I say that Banana bread initially turned into a standard component of American cookbooks with the promotion of heating pop and preparing powder in the 1930s. It showed up in Pillsbury's 1933 Balanced Recipes cookbook,and later increased more acknowledgment with the arrival of the first Chiquita Banana's Recipe Book in 1950.

National Banana Bread day is 23 February.Bananas showed up in the US in the 1870s and it took a while for them to show up as fixing things for desserts.[citation needed] The advanced banana bread recipe[5] started being distributed in cookbooks around the 1930s and its prominence was significantly helped by the presentation of heating powder available.

Some sustenance students of history trust banana bread was a result of the Great Depression as creative housewives did not wish to discard overripe bananas (as they were as yet an expensive thing to buy), others trust the cutting edge banana bread was produced in corporate kitchens to advance flour and preparing pop items @adsactly.
