Whole Milk and Butter (Best Option)
For every 1 cup heavy cream, use 3/4 cup whole milk + 1/4 cup melted unsalted butterHeavy cream is about 36-40% fat, which contributes to tenderness and moisture retention in yeast bread. Combining whole milk (3.5% fat) with melted butter increases the fat content to approximate heavy cream, supporting gluten development and yeast fermentation without compromising dough structure.
To ensure even fat distribution, melt the butter and mix thoroughly with the milk before adding to the dough. Use at room temperature to avoid shocking the yeast. This substitute maintains the dough's hydration and fat balance, which is critical for crumb softness.
The final bread will have a texture and flavor very close to that made with heavy cream, with a tender crumb and good rise, though it may be slightly less rich in mouthfeel.
