Half-and-Half with Butter (Best Option)
3/4 cup half-and-half + 1/4 cup melted unsalted butter per 1 cup heavy creamHeavy cream is about 36-40% fat, which contributes to the tenderness and richness of chocolate chip cookies. Combining half-and-half (10-12% fat) with melted butter raises the fat content to approximate heavy cream, preserving the dough’s structure and mouthfeel.
To ensure success, melt the butter and mix thoroughly with chilled half-and-half before adding to the dough to prevent separation. Use immediately for best results.
This substitute yields cookies very close in texture and flavor to those made with heavy cream, maintaining the desired chewiness and richness without noticeable differences.
