So I've always used the same recipe for banana bread, but

Take however many eggs the recipe calls for. Separate them, and add the yolks to the batter.

With the whites, whisk them vigorously for several minutes until peaks form. Then, gently fold the whipped whites into the rest of the ingredients at the end.

This and be careful the eggwhites and yolks are at least room temperature

You had too much liquid in comparison to the starch, so the bread didn't hold up to its own weight. The egg separation is a good idea, but if you want a cakier texture, do what you did and add a few tablespoons of corn starch. This will also lend crispiness to the crust.

And for god's sake don't whisk the batter. You'll develop the gluten in the flour and get a tough, peaked, and tunneled loaf. Gross.

Thanks. I'm not using any eggs so I'll try the corn starch.

seeing as others already corrected the culinary mistakes: the verb you were looking for is deflate, not deinflate.

Just use almond flour instead of flour...

The structure that typically keeps the bubbles of air suspended in the finished bread, providing structure, is gluten.

Quickbreads such as banana bread do not have gluten developed in them, and instead usually use eggs as a leavening agent, because people find that the tougher structure of bread caused by developed gluten is not suitable for sweet quickbreads whereas eggs provide a springy, less chewy structure.

I actually like a bit more bight to my banana bread, and I do develop the gluten, though I understand how others may not like that.

There are several things you can do in this knowledge. One is that you could tweak how you use the eggs:

> Use MOAR EGGS
> Try whipping the whites like this anon said >>8458159, so that the egg-white meringue provides additional stability and leavening

You could also tackle it in another way - your problem is that you used too much liquid, so you could try reducing the liquid. One way would be to dry the banana, for example by mashing and wrapping in cheese-cloth and squeezing, or sprizing with lemon juice (to preserve color) and dehydrating slightly in a dehydrator or a toaster oven on the lowest setting. This will concentrate the flavor while removing moisture.

Or, instead of using more milk, you could use a higher-fat dairy and just use less overall.

Another option would be to add an egg-replacement product such as flax eggs or chia eggs. In either case, you just grind them/mix with water/let stand, and you end up with a gelatinous substance that can bind much like eggs, while lending a sort of nutty taste and some omega 3s.
