White Sugar + Molasses (Best Option)
1 cup white sugar + 1 tablespoon molasses per 1 cup brown sugarBrown sugar is essentially white sugar combined with molasses, which contributes moisture and a rich caramel flavor. By mixing white sugar with molasses, you replicate both the sweetness and the hygroscopic properties that keep pie crust tender and flavorful.
For best results, thoroughly combine the molasses with white sugar to ensure even distribution. This prevents clumps and ensures consistent moisture throughout the dough. Adjust slightly if the dough feels too wet or dry.
This substitute yields a pie crust very close in texture and flavor to the original, preserving flakiness and subtle caramel notes without introducing off-flavors or excess moisture.
