Water (Best Option)
1:1 by volumeWater works as a substitute because it provides the necessary moisture for dough formation without adding any competing flavors. Since chicken broth is not a typical ingredient in chocolate chip cookies, its absence does not affect the recipe’s chemistry significantly.
When using water, ensure it is at room temperature to maintain dough consistency and avoid affecting yeast or leavening reactions, although these are minimal in cookies.
The final cookies will taste as intended by the original recipe, with no savory notes or textural changes introduced by broth.
