What can be used as substitute for oil in baking a cake?

Here's a list of possible substitutes for oil in baking a cake:

Applesauce: Applesauce can be used as a substitute for oil in cakes, muffins, and other baked goods. It adds moisture and sweetness, and it can also help to reduce the amount of fat in a recipe. Use about 3/4 cup of applesauce for every 1 cup of oil called for in the recipe.

Banana: Mashed bananas can be used as a substitute for oil in cakes, muffins, and other baked goods. They add moisture, sweetness, and a rich flavor. Use about 1 cup of mashed banana for every 1 cup of oil called for in the recipe.

Avocado: Mashed avocado can be used as a substitute for oil in cakes, muffins, and other baked goods. It adds moisture, richness, and a slightly nutty flavor. Use about 1 cup of mashed avocado for every 1 cup of oil called for in the recipe.

Yogurt: Yogurt can be used as a substitute for oil in cakes, muffins, and other baked goods. It adds moisture, richness, and a tangy flavor. Use about 1 cup of yogurt for every 1 cup of oil called for in the recipe.

Buttermilk: Buttermilk can be used as a substitute for oil in cakes, muffins, and other baked goods. It adds moisture, richness, and a tangy flavor. Use about 1 cup of buttermilk for every 1 cup of oil called for in the recipe.

Vegetable or Fruit Purees: Purees made from vegetables like pumpkin, sweet potato, or carrots, or fruits like mango or papaya can be used in baking as well as oil. Each puree may impart its own unique flavor and consistency to the cake, so taste and adjust as needed.

When substituting oil with any of these options, keep in mind that the texture of the final baked good might be slightly different from the original recipe. It may also be necessary to adjust the amount of other ingredients in the recipe, such as flour and liquid, to achieve the desired consistency. It is always a good idea to test a small batch before committing to a larger one.
