It is not a timing problem. It is a geometry problem, and the recipes we compared show exactly why.
We weighed the finished cookie in 82 of the 85 recipes we compared and read 7,124 reviews for what cooks said about the centre. A bigger cookie is supposed to still look wet in the middle when the edge is done: the two are decided by different physics, and the gap between them widens with size. We will not hand you a minute count. We will tell you what to look at instead.
A minute count or a degree. We hold no structured oven temperatures or bake times, only whatever a recipe's own author happened to write in their method text, and those recipes disagree with each other on both. Anyone selling you one number for every cookie is guessing at the size of your dough ball. Use the visual cues below instead, or start from the wider troubleshooting hub if the problem is really spread, not doneness.
Mass and surface-to-volume decide how far the edge dries before the centre sets. Edge and centre are separately controllable — which is why a cookie can be crisp outside and soft inside without contradiction.
We have a weighed cookie for 82 of the 85 recipes we compared. The smallest finished cookie in that set is 20 g; the heaviest is 166 g. Between those two, 16 recipes land under 35 g and 19 sit over 60 g, 10 of those over 70 g. A typical cookie in our corpus runs close to 46 g, and the middle half sit roughly between 36 g and 58 g.
Cookie mass never turned into one of the two fitted levers below. Not because the effect is not real, it is basic physics, but because our reviews compare cooks who changed the egg or the butter and told us what happened, not cooks who ran a controlled test on how many grams of dough they scooped. The mechanism is universal even where we have no fitted vector to point at. It is also why edge and centre can be judged separately without contradiction: they are set by different physics, running on different timers, inside the same cookie.
These hold across recipes of every size, so they stack with the geometry above rather than replacing it.
Recipes with more butter in the dough come out gooier in the middle. butter changes whether the butter's own water reaches the flour, which decides chewy against cakey before the oven is involved.
Recipes with more egg in the dough come out more set in the middle. More egg sets the crumb sooner, so the middle finishes firmer and holds its shape.
Not a defect. The whole point of a bakery-style cookie is this exact contrast, deliberately exploited rather than avoided.
This is not a fringe case: 19 of the recipes we compared build a cookie over 60 g, 10 of those over 70 g, against 16 recipes under 35 g. If the last cookie you baked was on the heavier side of that split and you judged it against a memory of a smaller one, the comparison was never fair to begin with. If you want the big, deliberately-underdone-looking centre on purpose, that is what a bakery-style cookie is built to do. It leans into this same gap rather than fighting it.
These are quotes from recipes' own method text, not our recommendation. Read them together and you can see why we did not fit one.
Double the batch and freeze half the raw dough, then defrost it in the fridge overnight to bake small batches on demand.

Level off your quarter-cup scoops and don't reshape the dough once it's on the sheet -- it spreads a bit more evenly.
9 cooks reported this
Pull the cookies out a couple minutes early -- cutting the bake time from about 12 minutes to 10 -- for a chewier texture.
8 cooks reported this
Bake a few minutes longer, or a bit hotter, for deeper browning.
7 cooks reported this
Refrigerate the dough for about an hour and let the cookies finish setting on the hot baking sheet after they come out of the oven, for deeper, more golden-brown color.
6 cooks reported this
Add a bit more flour than the recipe calls for to keep the cookies from spreading as much, though results aren't universal -- one baker still saw more spread despite the extra flour.

Two of the recipes quoted above chill the dough for opposite stated reasons: one says it is for a thicker cookie that spreads less, another says it is for chew. Both are right for the recipe they belong to. That is exactly why a bake time or a chilling step lifted from any one recipe's method text is a fact about that recipe, not a rule about cookies, and exactly why size, not the clock, is the variable that actually generalises.
Refrigerate the dough for about an hour and let the cookies finish setting on the hot baking sheet after they come out of the oven, for deeper, more golden-brown color. 6 cooks mentioned this. The cookie keeps cooking on a hot tray after the oven door opens, which is part of why a centre that looks slightly underset the instant you pull it is often exactly where you want it.
Every number you saw above the reviews came from a recipe's own method text, not from a structured field we fitted the way we fitted sugar or butter. We never built "bake time" or "oven temperature" into an axis, so we have nothing to average into a universal figure, and averaging recipes that disagree by 25 degrees would only manufacture a false confidence, not remove it.
A bigger portion keeps its centre underdone while the edge sets, widening the gap between the two. We can state that mechanism with confidence because it is basic geometry, but it never became one of the two measured levers above. Nobody in our reviews ran the experiment of changing only the dough-ball size and telling us what happened.
Oven calibration, tray colour, whether you baked one sheet or two at once, all of these move how a cookie's edge and centre set, and none of them are in our data. The visual cues above generalise across all of that. A minute count does not.
