โญ Applesauce (unsweetened) (Best Fat-Free Option)
1 tablespoon applesauce per 1 tablespoon butterApplesauce is a fat-free, moist substitute that can add moisture to French toast but does not provide the fat necessary for proper browning or the rich mouthfeel butter imparts. The sugars in applesauce may caramelize slightly, but the lack of fat limits the Maillard reaction.
Use applesauce combined with a small amount of oil or cooking spray to improve browning. Monitor cooking closely to avoid sogginess.
The texture will be softer and less crisp, with a subtle fruity sweetness that changes the traditional flavor profile.
