I made my first batch of chocolate chip cookies, but I'm not sure if they're supposed to turn out the way they did. The cookies came out thick the way I wanted them too..not too much spreading. But when I bite into one, I get a crispy exterior, but then the middle is chewy. Should a chewy cookie be chewy all the way through? Also, there was slight browning of the outside of the cookie...imagine that the surface of the cookie is mountain peaks and valleys...the peaks have some slight browning, but not the valleys...so the cookie isn't a uniform color.
