Unsweetened applesauce can be used to replace part or all of the butter or oil in a recipe. It can be swapped in equal quantities, so if a recipe calls for 2 cups of butter, you could replace as much of it as you'd like with applesauce, from a small amount such as 1⁄4 cup to the entire amount. In this recipe, we're still adding in 2 tbsp oil for maximum moistness and the best texture.
