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 back in, which provides moisture and a characteristic caramel flavor. Mixing white sugar with molasses recreates this balance, ensuring the cake retains its tender crumb and rich taste.
For best results, thoroughly mix the molasses into the white sugar until evenly distributed to avoid clumps. Use the substitute immediately as the texture can harden if stored.
Compared to using brown sugar directly, this substitute yields nearly identical texture and flavor, preserving the cake's moistness and subtle caramel undertones essential for chocolate cake richness.
