Standing croissants up slightly, arrange bottom halves in 2 rows, alternately overlapping them slightly in a 9 x 13-in. baking dish. Scatter half of brownsugar mixture overtop.
- Ladle half of custard mixture over croissants. Lay remaining croissants, top-side up, in 2 rows, alternately overlapping them slightly. Pan will be extremely full. Scatter remaining brown-sugar mixture overtop. Pour in remaining custard mixture. Using your hands, press on tops to make sure croissants are covered in custard. Let sit for another 5 min to soak up liquid.

Day-old croissants are best for this pudding because they will soak up all the liquid. To make ahead, prepare custard and refrigerate. Toast croissant halves. Assemble and let stand while preheating oven.
