The original recipe uses one egg. This version uses 3 tablespoons aquafaba, which produces a chewy cookie with crisp edges.

Other options for replacing one egg:

Prepared egg replacer: Use the amount indicated on the package for one egg. This is the most neutral alternative.
Flax egg: Mix 1 tablespoon ground flaxseed with 3 tablespoons water and let it thicken for 5–10 minutes. The cookies may be slightly denser and nuttier.
Unsweetened applesauce: Use 1/4 cup. The cookies will be softer and more cake-like.

Chilling the dough for at least an hour is important for its structure and texture.
