I think i added tbs instead of tsp.
Will this damage the dough? I tried making some cookies. but i was afraid to taste them. I have over 100 cookies i need done for Saturday. Will it taste bad? Should/Can i add a sweet icing to make it better?

Thanks!

Certainly taste what you've made. If they taste okay, than you're golden. If they taste yucky, you'll have to dump what you have and start over. Bummer, but necessary.
