Kimmyt - check out the cookbook CookWise by Shirley O. Corriher - she has 4 chocolate chip cookie recipes in that book. One basic, one thin, one puffed, and one “In Between”. I think you’ll find the differences interesting. If you want to play around with your own recipe, Shirley has several suggestions for controlling the spread, puff, tenderness, and color of your cookies.
Our family’s favorite would be the thin ones - they’re thin, but soft and chewy, and very intensely flavored! (plus there are no eggs in the thin recipe, so you can eat it raw without fear)
