Ok so I basically follow this no-flour PB cookie and I add chocolate chips (I use 1/4 white sugar and 1/2 brown sugar instead though).

I'd like to somehow make it into one big cookie. I don't like scooping stuff out into the pan and making it all even 'cause it takes me forever for this recipe. Is there a specific sized pan I need to use and how long would I bake it for if I do this?
