Whole Milk + Unsalted Butter (Best Option)
3/4 cup whole milk + 1/4 cup melted unsalted butter per 1 cup heavy creamHeavy cream is about 36-40% fat, which contributes to the tenderness and flakiness of biscuits by coating flour proteins and limiting gluten formation. Combining whole milk (3.25% fat) with melted unsalted butter (80-82% fat) recreates this fat level, maintaining the dough’s richness and moisture balance.
To ensure success, melt the butter and mix it thoroughly with the milk before adding to the dough. Keep the mixture cold to prevent premature gluten development and maintain biscuit rise.
Compared to using heavy cream, this substitute yields biscuits with very similar texture and flavor, with only a slight difference in richness that is generally imperceptible.
