There are several reasons cookies spread.Recipe
A touch too much sugar, for one – sugar is hygroscopic; it absorbs liquid. When you’re preparing your dough, it may LOOK just fine (as the sugar is holding onto the liquid); but once it bakes, and the sugar releases that liquid it had been hoarding, watch out for those puddles!
Frank, our veteran chef and test kitchen baker, recently sent me photos from an experiment on cookie spread he’d just conducted.
Says Frank, “We’re working on different aspects of cookie baking, and thought you might enjoy these test results. The primary difference between these two trays is the baking temperature. The failed tray baked at 350°F for 14 minutes. For this practically perfect tray, we dropped the temperature to 300°F, and extended the baking time: 22 minutes for chewy, 30 minutes for crisp.
And why, exactly, does baking temperature affect cookie spread? Because the fat in cookies is a big part of their structure, prior to baking. Scoop the dough onto the baking sheet, and the fat is at least partially responsible for them holding their shape. Once those cookies hit the oven, though, the fat starts to soften and melt. And the hotter the oven, the more quickly it melts. If the oven’s hot enough, the fat melts before the cookies set. And since their flour/liquid matrix hasn’t yet had a chance to harden, the cookies spread – becoming those dreaded cookie blobs.
Do you have a favorite cookie recipe that spreads too much? Try lowering the temperature, and baking the cookies longer; this trick just may give you the perfect treat you’re after.
