I highly recommend using a metal 9 by 5-inch loaf pan for this banana bread recipe. Glass and ceramic pans can take much longer to bake and may result in underbaked and collapsed bread. If you only have a glass or ceramic pan, adjust the baking time accordingly and use the tips below to ensure the bread is fully cooked. It's also important to use the correct pan size - while an 8 1/2 by 4 1/2-inch pan may seem similar, the difference in volume can greatly impact the final product. Using a smaller pan can cause the bread to spill over and become underbaked in the center.
