Brown Sugar (Best Option)
1 cup brown sugar per 1 cup granulated sugarBrown sugar contains molasses, which retains moisture and contributes to a tender crumb in banana bread. The caramel notes complement the banana flavor well, enhancing overall taste.
When substituting, pack the brown sugar lightly to avoid over-sweetening and monitor baking time as the bread may brown faster due to molasses content.
The final product will be moister and have a deeper flavor profile compared to using granulated sugar, with a slightly darker crumb and softer texture.
