Half-and-Half with Butter (Best Option)
3/4 cup half-and-half + 1/4 cup melted butter per 1 cup heavy creamHeavy cream is approximately 36-40% fat, which contributes to moisture retention and tenderness in quick bread. Combining half-and-half (10-12% fat) with melted butter raises the fat content close to that of heavy cream, replicating its functional properties.
To ensure even distribution, melt the butter and mix thoroughly with half-and-half before adding to the batter. Avoid adding hot butter to prevent cooking eggs or activating leaveners prematurely.
This substitute yields a quick bread with a texture and richness very close to the original, preserving moistness and crumb softness without altering flavor significantly.
