FAQs
1. Can I use fresh bananas instead of overripe ones?
It’s best to use overripe bananas since they are sweeter and will provide better flavor and moisture to the bread.
2. What can I do if I don’t have golden syrup?
If you don’t have golden syrup, you can brush the bread with honey or maple syrup instead for a similar sweet glaze.
3. Can I use whole wheat flour instead of all-purpose flour?
Yes, you can use whole wheat flour, but it may change the texture slightly. You can also mix both for a healthier option.
