What about eggs in cookies?

When in doubt (or just as a rule), use Egg Replacer in cookies. It’s great and it works.

I imagine the flax seed “egg” would work well too, but the thing is, I don’t like nuts in my cookies so I don’t want the nutty, healthy flavor that flax produces.

Flax seed “egg”, equivalent of one chicken egg:

1 Tbls ground flax
3 Tbls hot water

Whisk and let sit for a couple minutes until a gel forms.
