Cookie math is simple until you run out of dough halfway through the last tray. This free cookie batch yield calculator turns total dough weight and scoop size into a cookie count, a tray count and leftover dough. It is the fastest way to plan a bake sale, a party or a freezer stash without counting scoops one by one.
Start by weighing your dough, not by guessing from cups. Flour packs differently every time you scoop it, so cup measures drift from batch to batch. A kitchen scale gives one honest number for the whole bowl. Weigh the empty bowl first, or tare the scale, so you only count dough. That single habit makes every later number in the tool accurate.
Scoop size is the second input, and it decides both count and bake time. A 30 gram scoop makes a classic medium cookie. Smaller scoops bake faster and give more cookies, which suits kids and party platters. Larger scoops bake slower and stay soft in the middle, which suits thick bakery-style cookies. Keep scoops even, or small cookies will burn while big ones stay raw.
The calculator divides total dough by scoop weight and rounds down, because a partial scoop is not a cookie. It then divides the count by twelve for standard trays, rounding up, since a half-full tray still counts as a tray. Leftover dough is shown in grams, so you know whether to make one small cookie, save it for tomorrow or eat it as baker’s treat.
Tray planning matters more than it looks. Cookies spread as they bake, so crowding a tray fuses them into one giant cookie. Twelve per standard tray is a safe default for medium scoops. For large scoops, drop to nine per tray and give each cookie room to spread. The tool counts trays, not oven loads, so check how many trays fit your oven at once.
Bake time changes with scoop size, even when the recipe stays the same. Small cookies may need two or three minutes less, and large cookies may need three or four minutes more. Check the smallest cookies first and pull trays when the edges look set and golden while the centres still look slightly soft. They firm up as they cool on the tray.
Freezing is a great use for this calculator. If the count is higher than you need today, scoop the extra dough onto a tray, freeze until firm, then bag the frozen scoops. Frozen scoops bake straight from the freezer with two or three extra minutes. Label the bag with scoop weight and bake temperature so future you does not have to guess.
Dough with chunks needs a little care. Chocolate chips, nuts and dried fruit make scoops uneven if you scoop carelessly. Stir the dough well before portioning, and press each scoop gently so chunks sit inside, not on the surface where they burn. If a scoop comes out light on chunks, top it with a few chips before baking.
Scaling works cleanly with weight. Doubling a recipe doubles the dough weight, and the calculator doubles the count. Halving works the same way. This is far more reliable than doubling cups, where packing errors double too. For bake sales, work backwards: decide how many cookies you need, multiply by scoop weight, and weigh out exactly that much dough.
Try the tool with your next batch. Weigh the dough, pick your scoop, and compare counts before you start portioning. That one minute of planning tells you how many trays to line, how long baking will take, and whether you have enough for the freezer. Good cookie batches start with numbers, not with hope.
