Our final test! Thank goodness. Who knew you could get tired of cookies?!
We noticed our cookie dough was a little more runny this time and the cookies looked kind of oily. I'm not sure if that was because of the replacer or because it was ridiculously hot and humid this week. Whatever the issue was, the dough and cookies tasted fine. They became very flat five minutes after getting out of the oven but that seemed to be a common problem with all the replacements we tried.
So to summarize our results, chia seeds are the only ones that we would suggest you never try. All the rest will work and give you decent results. Our order from best to worst is:
#1 Arrowroot Powder
#2 Ener G Egg
#3 Hemp Seeds
#4 Flax Seeds
#5 Chia Seeds - seriously, don't use these. Skip the cookie and just eat the chocolate chips!
Our experiment is done for now but if anyone has any other substitutes they'd like us to try in the chocolate chip cookies, let us know. Also leave a comment if you'd like us to try any of these replacements in some other recipe.
