⭐ Water with a pinch of salt and a splash of apple cider vinegar (Best Dairy-Free Option)
1 cup water + 1/8 tsp salt + 1/2 tsp apple cider vinegar per 1 cup vegetable brothWater is the neutral base that provides moisture necessary for the cake's structure. Adding a pinch of salt helps mimic the slight seasoning in broth, while apple cider vinegar adds mild acidity that activates baking soda, crucial for the cake’s rise and tender crumb.
For best results, mix the vinegar into the water just before adding to the batter to preserve its leavening effect. Avoid overusing vinegar as it can impart a tangy note if excessive.
This substitute keeps the carrot cake’s flavor profile clean and sweet, closely resembling the original texture and rise achieved with vegetable broth.
