โญ Brown Rice Syrup (Best Vegan Option)
1:1 (1 cup brown rice syrup per 1 cup maple syrup)Brown rice syrup is a good substitute because it is a liquid sweetener with a similar consistency to maple syrup, allowing it to blend well into the banana bread batter. Its lower sweetness level means it won't overpower the banana flavor.
Since it is less sweet, you may want to increase the quantity slightly or add a small amount of granulated sugar to compensate. Also, it tends to make baked goods chewier, so monitor the baking time to avoid excessive density.
The resulting banana bread will be less sweet and have a subtle malted flavor, which can complement the bananas but is less rich than maple syrup.
