⭐ Water (Best Vegan Option)
1:1 (replace beef broth with equal volume of water)Water works because the primary role of beef broth in a vanilla cake recipe would be to provide moisture. Since beef broth contains strong savory flavors and salt, replacing it with water avoids flavor contamination. The food science here is that water hydrates flour and dissolves sugar and other ingredients without altering flavor.
For best results, use room temperature water to ensure even mixing and proper gluten development. Avoid using hot water as it can prematurely activate leavening agents.
Using water results in a clean, neutral flavor profile that highlights the vanilla and sweetness, unlike broth which would introduce unwanted savory notes.
