⭐ Lemon Juice (Best Vegan Option)
1:1 (1 tablespoon lemon juice per 1 tablespoon white vinegar)Lemon juice contains citric acid, which reacts with baking soda to produce carbon dioxide, helping the cake rise similarly to white vinegar’s acetic acid. The acidity level is close enough to maintain the chemical leavening balance.
For best results, use freshly squeezed lemon juice to avoid bitterness from bottled versions. Monitor the batter consistency as lemon juice is slightly more liquid but generally interchangeable.
The final cake will have a slightly fresher, brighter flavor profile with a subtle citrus undertone that complements the chocolate, often perceived as more complex and appealing.
