The type of pan you use when cooking a sweet bread can greatly affect the outcome. While glass and stoneware are good for some cooking projects, you should opt for darker metal loaf pans when making banana bread. Dark metal pans promote more even cooking and help to ensure a well-browned crust and a center that is fully cooked. Whatever type of pan you use, grease and flour it before pouring in your batter to prevent sticking.

Banana bread is typically cooked at 350 degrees Fahrenheit on the lower middle oven rack position. If your bread is turning out still gooey in the middle, check your oven's temperature to ensure that your oven is getting hot enough. Use an oven thermometer to check the oven temperature. If you find your oven is running cooler than expected, adjust the heat setting to compensate for the temperature discrepancy.

One 9-inch loaf of banana bread takes at least 55 minutes to cook. Set a timer for 55 minutes when you put the bread in the oven. When the timer goes off, do not immediately remove the bread and turn off the oven. Instead, insert a toothpick into the center of the bread. If the toothpick comes out clean, it is done. If it is wet with batter, give the bread five more minutes and try again until the toothpick comes out clean. Let the bread sit for five minutes in the pan before removing it.

If you over-mix your batter, it can lead to problems. Banana bread rises best when the wet and dry ingredients are only lightly mixed together. When you mix the batter thoroughly, the gluten proteins form into long and orderly bundles which in turn produce a solid batter that does not rise well. When it doesn't rise as much as it should, the center of your banana bread may not cook thoroughly. Gently fold the wet and dry ingredients together only until there is no unincorporated flour.
