Which baking dish is best to bake a banana bread? When I bake a banana bread or cake at home, I always use a square Pyrex(about 20cm in width and 7 cm high) dish.  The batter only fill the dish at half its height or less and I set my oven to 350F.  I bake the banana bread for 30 min in the middle of the oven and when I check for doneness, the middle part is a bit wet(about 90% done) while the surrounding area is perfectly done.

Is a square Pyrex a good way to bake banana bread and cake or should I get a loaf pan or bundt shape one?  Does a loaf pan bake the banana bread or cake evenly in a set period of time?  From this recipe, the baking time in the load pan seems to be 1 hour compared to 30 min in the Pyrex.
"Best" is subjective.

The different choices of baking pans will effect texture and baking time. The more surface area the more crust and the faster the baking time.

Recipes call for a bread pan simply because then it looks like bread and is easier to slice. As you noticed, it does require longer to bake.

Muffin pans are also very popular because of the convenient shape and faster baking time.

If you like the shape and texture of your bread in a baking dish then by all means keep using it. I won't criticize you for it.
