I think there are recipes in Vegan Subs that use coconut flour.
Yes, there is a very good peanut butter with chocolate chips cookie recipe in Vegan Subs. I have made it a few times for a GF friend. No other flours are used, just the coconut flour.
I bought the bag of flour to make these cookies and thought the same thing...now what do I do. I have since used just a bit of it in other cookie and brownie recipes and I love it. If a recipe calls for 1 cup flour I just put in 1/4 cup coconut flour. You don't want to put too much in. I love using it. Everything I it in has just a hint of coconut to it and its wonderful. I'm now ready to buy another bag of the stuff.
