Here are the most common things that can go wrong during cookie baking—and how to fix them.
Solution: Use a portion scoop.
When cookies are portioned out larger or smaller than the recipe directs, they may not produce the intended texture. To ensure consistent size and the proper yield, we use a portion scoop.
Solution: Bake in staggered rows.
When scoops of dough are placed too close together on the sheet, the cookies can fuse together. To ensure enough space between cookies, alternate the rows. For example, place three cookies in the first row, two in the second, three in the third, and so on.
Solution: Underbake them.
To ensure a chewy texture, take cookies out of the oven when they are still slightly underdone, which often means they’ll droop over the end of a spatula. Crevices should appear moist and edges on smooth cookies should be lightly browned.
Solution: Briefly chill dough and don’t use a hot sheet
If cookies spread early in the oven, the edges can overcook. This can result from butter in the dough melting. If the dough seems too soft, chill it for 10 to 15 minutes before portioning. And let baking sheets cool completely between batches. To expedite cooling, rinse warm sheets under cold tap water, then dry thoroughly.
Solution: Immediately transfer the cookies to a wire rack.
Most recipes call for letting the cookies set up for a few minutes on the baking sheet before transferring them to a wire rack. But if you’ve overbaked your cookies, transfer them directly to a wire rack; otherwise they'll keep cooking from the residual heat of the baking sheet.
Solution: Reserve some morsels to add later.
When chocolate chips, nuts, or raisins are in the mix, the last few cookies from a batch never seem to have as many of these goodies as the first few. To get around this, reserve some of the mix-ins and stir them into the dough after about half of it has been scooped out.
