Can I substitute bread flour for AP flour in banana bread recipe? I have bread flour (King Arthur) at home all the time, but I don't usually have all-purpose flour, as bread is pretty much the only thing I bake from scratch. I want to make basic banana bread following this recipe. I have never made banana bread before. 

Can I substitute bread flour for the all-purpose flour? I also have stone-ground whole-wheat flour that I use for chapatis. Would some mixture of whole-wheat and bread flour be a better substitute? The reviews for the banana bread recipe say that it results in a dense loaf, so would using bread flour make it even more dense and thereby unappetizing? 

I don't particularly want to keep all-purpose flour on hand in addition to bread flour and whole wheat flour, as my pantry has tons of flours already; ten at last count. I searched online and on this site but the questions typically seem to be about subbing AP flour for bread flour, or using some other flour instead of wheat flour. I was unable to find anything specifically about using bread flour instead of AP flour. 



Update I decided to risk replacing 1/3 cup of the bread flour with rice flour. I thought that since rice flour is lighter and has no gluten, it would offset the increased denseness caused by using a high-gluten flour. The banana bread turned out fine. 

I have posted a follow-up question about using maida in combination with bread flour to create an all-purpose flour substitute.
With some precautions in your mixing method, you could substitute Bread Flour for AP Flour in Banana Bread. Mind you, it may make a stronger, more dense, more chewy banana bread than people expect--but it would still be pallatable, some may even prefer it.

As discussion here points out: the main concern in the substitution is the higher gluten of bread flour.

I checked the King Arthur website, found that this bread flour is 12.7% protein (gluten). According to this chart from Cooking for Geeks (I am not affiliated with the book) indicates, this is low-to-average for gluten in bread flours:


Not over-mixing is critical in this situation, since mixing forms gluten. I can't describe better than @Sam Ley did here. Sam makes a great point: you should be comfortable leaving some dry clumps in the batter. 

Also, if tempted to sift the flour, I would hesitate. sifting the flour will increase powder surface area, which would facilitate more gluten formation.
