White Sugar + 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, acidity, and flavor compounds that influence yeast fermentation and gluten development. By mixing white sugar with molasses, you restore these critical components, ensuring the yeast bread rises properly and has the desired tenderness.
To achieve the best results, thoroughly mix the molasses into the white sugar until evenly distributed. Adjust dough hydration slightly if needed, as molasses adds moisture. Monitor dough consistency and rise times as they should closely resemble those using brown sugar.
The final bread will have a similar color, flavor depth, and moist crumb as when using brown sugar, making this the most reliable substitute in yeast bread recipes.
