⭐ Light Brown Sugar (Best Vegan Option)
1:1 by volumeLight brown sugar contains molasses, which imparts the subtle caramel and toffee notes needed to balance the acidity of the vinegar and richness of the butter in Béarnaise Sauce. Its moisture content helps maintain the sauce’s smooth texture without thinning it.
When substituting, measure light brown sugar exactly as you would brown sugar to keep the flavor and moisture consistent. Avoid packing it too tightly to prevent excess sweetness or moisture.
The final sauce will retain its classic flavor profile and creamy texture, making this substitute virtually indistinguishable from the original brown sugar.
