What makes this swap demanding for cookies

A chia 'egg' (1 tbsp seeds + 3 tbsp water) is engineered to mimic an egg's binding role, but the gel binds water far more aggressively than albumen does — roughly 12x its own weight. In a chocolate chip cookie that math reads as suppressed spread: the dough holds its shape, stays domed, and skews cakey instead of cracking open at the edges. Ground flax is the closer mimic when you want the silhouette to behave more like the egg version.

  • Already-wet doughs (oatmeal raisin, soft-batch, anything with applesauce or banana) compound the problem — the bound water suppresses edge browning and leaves a leaden interior.
  • Whole seeds bake in as dark flecks with a faint pop; grind them in a spice mill before hydrating if the cookie is meant to look smooth, like a sugar cookie or snickerdoodle.
  • Hydrate the gel a full 10-15 minutes off-heat before it touches the dough; under-set seeds keep pulling moisture during the rest and bake out dry and crumbly.
