Dark Brown Sugar (Best Option)
1:1 by volumeDark brown sugar contains a higher molasses content than light brown sugar, which closely replicates the moisture and flavor profile of standard brown sugar. This helps maintain the biscuit’s tenderness and slight chewiness.
When substituting, use the same volume measurement as brown sugar. Ensure it is well packed to match the moisture content. Watch for dough stickiness and adjust flour slightly if needed.
The final biscuits will have a slightly richer molasses flavor and similar moisture, maintaining the intended soft and flaky texture.
