I just realized that the batch of NFSC that I made yesterday and is in the fridge chillin, that I forgot to put the baking powder in. What is going to happen when I roll them out and bake them? Will they taste the same?

They probably won't rise very much and may be more dense....

Many CC'ers reduce the bp (I do) or leave it out entirely to reduce spreading. I do not believe that you will affect the taste.

I leave out the bp entirely and it prevents spreading as Tracy said. Your cookies will be just fine. Have fun!

i did the same thing yesterday. They were the best cookies I have ever eaten...unfortunately.

Add me to the list - I remove the BP completely form NFSC.

I usually cut the bp amount in half, except when I'm making chocolate cookies, and then I use the full amount. I could probably experiment with the amount in the chocolate dough, but I like the way it turns out as called for in the recipe....why mess with success?

I reduce it - usually by 1/2 (or more) also.
