When substituting apple sauce for oil in baking, it is a 1:1 ratio. 1/4 cup apple sauce for 1/4 cup oil (except for cookies). Some brands of boxed mix provide alternative directions for oil instead of butter. For a better result, use the oil recipe when substituting apple sauce.
Can you add applesauce to cake mix?
Follow the recipe for your cake. Replace the oil with the same amount of applesauce. For instance, if the recipe calls for 1 cup of oil, use 1 cup of applesauce instead. Use unsweetened applesauce to replace the oil in a cake recipe to avoid adding too much extra sugar to the cake.
