Detailed Guide: Each Whole Milk Substitute in Biscuits
Buttermilk
Buttermilk contains lactic acid which reacts with leavening agents like baking soda to produce carbon dioxide, helping biscuits rise and become fluffy. The fat content in buttermilk also contributes to a tender crumb.
When substituting, reduce or eliminate baking powder if the recipe calls for it, since buttermilk's acidity activates baking soda. Watch for slight flavor changes due to buttermilk's tang.
Compared to whole milk, buttermilk produces biscuits with a more pronounced rise, flakier texture, and a subtle tang that enhances flavor complexity without compromising moisture.
Half-and-Half
Half-and-half has a higher fat content than whole milk, which helps create a tender, moist biscuit by coating flour proteins and limiting gluten formation. It also adds richness and a creamy mouthfeel.
Use it as a direct 1:1 substitute without adjusting leavening agents. Be mindful of the slightly heavier texture and richer flavor.
Biscuits made with half-and-half tend to be richer and more tender than those made with whole milk, with a slightly denser crumb but excellent moisture retention.
Evaporated Milk
Evaporated milk is concentrated milk with about 60% of its water removed, so diluting it restores the consistency closer to whole milk. It contains similar fat and protein levels, which help with biscuit structure and tenderness.
Dilute before use to avoid overly thick batter. The slight caramel notes can add a subtle depth of flavor but may alter traditional biscuit taste.
Compared to whole milk, biscuits may have a slightly denser texture and a richer, slightly sweet flavor profile.
Coconut Milk (Canned, Full Fat)
Full-fat canned coconut milk contains a high fat content similar to whole milk, which helps create a tender biscuit crumb by limiting gluten development. The fat also contributes moisture and richness.
Because of its distinct coconut flavor, it works best in biscuits where a slight tropical note is acceptable. Use as a 1:1 substitute without adjusting leavening.
Biscuits made with coconut milk tend to be moist and tender but will have a noticeable coconut aroma and flavor, which may not suit all traditional biscuit recipes.
Soy Milk (Unsweetened, Full Fat)
Soy milk has a protein content closer to cow's milk, which helps with structure and moisture retention in biscuits. However, it generally has less fat, which can affect tenderness and richness.
Use unsweetened, full-fat soy milk to avoid adding unwanted sweetness. The mild beany flavor may slightly alter the biscuit's taste.
Compared to whole milk, soy milk biscuits may be a bit less tender and rich, with a subtle difference in flavor that some may find noticeable.

What NOT to Use as a Whole Milk Substitute in Biscuits
Water lacks fat and acidity, which are crucial for biscuit texture and flavor. Using water results in dry, dense biscuits with poor rise and no richness.
Almond milk is often too thin and lacks the fat content of whole milk, leading to biscuits that are less tender and can have a slightly nutty flavor that may not complement traditional biscuit recipes.
Skim milk lacks fat, which is essential for the tender crumb and moist texture of biscuits. Using skim milk can produce tougher, drier biscuits.
