Banana bread can become mushy for various reasons: 1.Underbaking: Ensure that the banana bread is baked for the recommended time. Underbaking can leave the center mushy. 2. Excessive Moisture from Bananas: If the bananas used are overly ripe, they can contribute excess moisture to the batter. 3. Overmixing the Batter: Overmixing the batter can break down the gluten structure, resulting in a mushy consistency. Mix the ingredients until just combined. 4. Improper Cooling: Allow the banana bread to cool properly before slicing. Slicing too soon can cause the interior to appear mushy. Adjusting these factors should help improve the texture of your banana bread.
