Cookie questions, answered.

Usually the butter was too warm or melted, there was too little flour, or the dough hit a hot pan. Chill the dough 30 to 60 minutes, measure flour by weight, and always start on a cool sheet. We log the spread you should expect on every recipe so you can tell if something is off.

Lean on brown sugar over white, add an extra egg yolk, and pull them from the oven when the centers still look slightly underdone; they finish setting on the sheet. A spoon of cornstarch in the dough also keeps them tender.

For high-butter doughs, yes. Chilling firms the butter so the cookies spread less, hydrates the flour, and deepens the flavor. Thirty minutes is the minimum; overnight is better. Low-spread doughs like shortbread can sometimes skip it, and we say so when they can.

Softened butter at cool room temperature (about 65F) creams with sugar to give lift and chew, and it is the default. Melted butter makes a denser, chewier, flatter cookie. Browned butter adds a nutty depth but you lose a little moisture. Avoid warm, oily butter, which makes cookies spread into puddles.

Brown sugar brings moisture, chew, and caramel notes from the molasses; white sugar promotes spread and crisp edges. More brown means chewier, more white means crispier. We state the ratio on every recipe so you can shift it to your taste.

Baking soda promotes spread and browning and needs an acid like brown sugar to activate. Baking powder gives lift and a cakier, less-spread cookie. Many cookies use soda, some use both, and they are not interchangeable one-for-one.

By weight in grams if you can; it is the single biggest fix for inconsistent cookies. If you use cups, spoon the flour into the cup and level it off, never scoop straight from the bag, which can pack in 20 percent extra and give you dry, cakey cookies.

Most drop cookies bake at 350F for 9 to 12 minutes. Pull them when the edges are set but the centers still look slightly underdone, then let them finish on the hot sheet for a few minutes. Rotate the pan halfway for an even bake.

Too much flour, too much leavening, creaming too much air into the butter, or an extra egg white. Use less flour measured by weight, mostly brown sugar, and an extra yolk rather than a whole egg.

Yes, and it is the best trick for fresh cookies any night. Scoop the dough into balls, freeze them on a tray until solid, then bag them. Bake straight from frozen, adding one to two minutes. Dough keeps up to three months.

Store them airtight with a slice of sandwich bread; the cookies pull moisture from the bread and stay soft for days. Keep crisp and soft cookies in separate containers so the crisp ones do not go soft.

Only if it is made for eating raw: no eggs, and the flour heat-treated. Raw flour can carry E. coli, so bake it on a tray at 350F until it reaches 165F, or microwave it in short bursts, before mixing. Our edible dough recipes spell out this step every time.
