Soft, chewy ube crinkle cookies with a cracked purple and white sugar coating.
Chill the dough the full hour; shortcutting it is the single biggest reason the tops stay smooth instead of cracking. If your ube halaya is on the wet side, add the extra tablespoon of flour mentioned in the variations so the dough isn’t sticky once it comes out of the fridge.
