Cut, rolled, chilled
Gingerbread cutout cookies that hold their shape
Cut the leavening back. That's the one change in this corpus with a proven effect on spread. Whether you roll and cut the dough or scoop it did not show a measurable effect on the finished cookie -- we tested for one on four outcomes and couldn't find it.
Gingerbread is unusual among the cookies we've built pages for: 73 of 190 recipes roll the dough flat and cut shapes from it, well over the 103 that scoop it, with one lone recipe baked as a single slab. Rolled, cut-out dough is the default here, not the detour. Below: the four things we tested that came back with no confirmed difference, and the one lever, leavening, that did.
