KAREN QUESTION I can not bake cookies. All of my baked cookies go flat. I have cookies look great fresh out of the oven and then go flat in minutes and I have had cookies go flat in the oven. I have an oven thermometer, I have tried hand mixing and have tried margarine versus butter to no avail.
ROSE REPLY use a lower protein flour such as bleached all-purpose flour. unbleached has higher protein which ties up the liquid keeping it from turing to steam and puffing up the cookie. also, after shaping the cookies, refrigerate them for at least 30 minutes or freeze them for 10 minutes if you have freezer space. that way they can set in the hot oven before they start to spread. if this doesn't help enough, try increasing the oven heat by 25 degrees.
