⭐ Applesauce (unsweetened) (Best Fat-Free Option)
3/4 cup applesauce per 1 cup vegetable oil Quick tip: Reduces fat and adds moisture but can make the cake denser and slightly sweeter.
Applesauce acts as a fat replacer by adding moisture and some natural sugars, which helps keep carrot cake moist despite lower fat content. The pectin in applesauce also contributes to structure.
Because applesauce contains water, reduce other liquids slightly to avoid a soggy batter. Use unsweetened to control sweetness.
The cake will be softer and denser with a subtle fruity flavor, and less greasy than with oil, which may be desirable for a lighter version.
