โญ Soy Milk (unsweetened, plain) (Best Dairy-Free Option)
1 cup soy milk per 1 cup whole milkSoy milk contains proteins that help with structure and moisture retention, making it one of the best plant-based milk substitutes. Its neutral flavor profile works well with chocolate.
Since soy milk is lower in fat than whole milk, consider adding a tablespoon of neutral oil per cup to compensate for fat loss. Avoid sweetened or flavored varieties to prevent altering the cake's taste.
The final cake will be slightly less rich and tender but still moist and flavorful, suitable for dairy-free diets.
