How do you make your cookies puffy?

Answer 1

The puffiness of cookies I believe is from the fat that is added to the recipe. The use of butter, margarine and solid vegetable shortening play a difference. I think a crisco type product gives a puffier cookie. I suggest trying all three and find out which gives you the desired end product. Flat or puffy? Sounds like a fun test They are all edible!!

Answer 2

Make the batter thicker and cook them over a lower temperature. They'll take a little longer to cook thoroughly, but they'll be fluffier.
