Dark Brown Sugar (Best Option)
1:1Dark brown sugar contains a higher molasses content than light brown sugar, which provides moisture and a deeper caramel flavor essential for tender crepes. The molasses also contributes to slight acidity, which can enhance browning and flavor complexity.
When substituting, use the same amount by weight or volume. Be mindful that the darker flavor may slightly deepen the crepes' taste but will not negatively impact texture.
The final crepes will have a richer flavor and similar softness compared to those made with light brown sugar, making it the closest and most reliable substitute.
