See recipe-specific answer →How do I substitute soy milk in pancake and waffle batter?
Use Whole Milk at 1:1 — Same protein range. Drop-in for vegan-to-dairy swap. Mix as the original recipe directs, then taste and adjust liquid or bake time in small steps after a test batch.
See recipe-specific answer →Will whole milk work as a soy milk substitute in yeasted dough?
Yes, at 1:1. Same protein range. Drop-in for vegan-to-dairy swap. Bake-test before scaling up.
See recipe-specific answer →Worked Example
If a recipe calls for 1 cup soy milk (245g), start with your selected substitute's ratio, then run a small test bake before scaling.
Expect up to 6% variation in cup-based measurements due to brand and handling differences. Weight-first measuring is more reliable for structure-sensitive recipes.

When to substitute vs when not to
Substitutions work best in forgiving recipes like muffins, quick breads, and cookies. They're riskier in precision-dependent recipes like macarons, choux pastry, or laminated doughs where the original ingredient's exact properties (fat content, water content, acidity) are critical to the chemistry.
