White Sugar and Molasses (Best Option)
1 cup white sugar + 1 tablespoon molasses per 1 cup brown sugarBrown sugar is essentially white sugar with molasses added, which provides moisture and a rich caramel flavor. Combining white sugar with molasses replicates these properties, preserving the waffle's texture and taste. This substitution maintains the batter's viscosity and browning characteristics.
To ensure even distribution, mix the molasses thoroughly into the white sugar before adding to the batter. Watch for slight stickiness in the sugar mixture but this will not affect the batter negatively.
Waffles made with this substitute will closely mimic those made with brown sugar in terms of moisture, chewiness, and flavor depth, making it the most reliable alternative.
