They need an "It was your fault" option next to "Helpful"
Honestly I think the rice flour is a bigger component here than egg replacer. Most modern egg replacers I've used work perfectly as directed in cookie recipes.
Made for a really lovely mochi-like cake when I made some with it recently -- definitely can recommend for that purpose! But that's in a pan that's a mold for the shape not...free-standing.
(Side note, chopped strawberries are lovely in matcha cake)
Yeah, rice flour behaves very differently than wheat flour when heated.
Far lower protein content and its superfine. Great for lining bannetons, not for baking cookies.
It's nice for a roux, too.
"I replaced glue with water but the pieces won't stick together, this is terrible DIY instructions"
Fuck it, at that point, just grab some icing, make some pretty borders across the edges, call it a cookie cake. People can slice off however much they want.
For really big ones, it's even better. You can treat it like brownies, let the ones who want edges get their bits and everyone else gets to enjoy the chewy center.
Wait until the chocolate chips are semisolid but not completely hard, then cut into squares.
