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 about 36-40% fat, which contributes to the moist, tender crumb and richness in muffins. Combining half-and-half (10-12% fat) with melted butter increases the fat content to approximate heavy cream's properties, preserving the batter's consistency and baking performance.
For best results, melt the butter and mix thoroughly with chilled half-and-half before adding to the batter to ensure even fat distribution. Avoid overheating to prevent curdling.
Muffins made with this substitute will have a texture and flavor very close to those made with heavy cream, maintaining moistness and richness without noticeable differences.
