⭐ Applesauce (Best Fat-Free Option)
1/2 cup applesauce per 1 cup butter Quick tip: Using half the amount of applesauce reduces moisture overload and compensates for the lack of fat, but muffins will be denser and less tender.
Applesauce is primarily water and carbohydrates, providing moisture but no fat. Fat is crucial for tenderizing gluten and creating a soft crumb in muffins. Using applesauce reduces fat content drastically, which can make muffins denser and chewier.
To improve texture, combine applesauce with a small amount of oil or margarine if possible. Also, reduce other liquids slightly to balance moisture.
The final muffins will be moister but less rich, with a slightly gummy texture and less crumbly structure compared to butter-based muffins.
