Applesauce (Best Option)
1/4 cup per eggApplesauce works well as an egg substitute in sugar cookies because it provides moisture and some binding through its pectin content, which helps hold the dough together. The natural sugars in applesauce complement the cookie's sweetness without overpowering it.
For best results, use unsweetened applesauce to avoid adding extra sugar, and slightly reduce other liquids if the dough feels too wet. Mixing thoroughly ensures even distribution and proper binding.
Compared to eggs, applesauce yields a softer, more tender cookie with a slightly cakier texture but retains the classic sugar cookie flavor and chewiness.
