⭐ Baking Powder (Best Fat-Free Option)
1 1/2 teaspoons per 1 cup of flourBaking powder is a chemical leavening agent that releases carbon dioxide gas when moistened and heated, causing the batter to rise quickly. This rapid leavening suits carrot cake, which is a quick bread and does not require the slow fermentation yeast provides.
For best results, ensure the batter is baked immediately after mixing to maximize the leavening effect. Avoid overmixing to prevent gluten development that can toughen the cake.
Compared to yeast, baking powder yields a softer texture and a sweeter, cleaner flavor profile, which aligns well with the spice and sweetness of carrot cake.
