Join Sohla El-Waylly in the Bon Appétit Test Kitchen as she makes cinnamon-date sticky buns. Instead of the usual brown sugar and butter filling, the fluffy buttermilk-laced buns are filled with a cinnamon-scented date purée. To make these, you'll have to knead, fold, and work with yeast, but the end results are more than worth it. A quick note on substitutions: The places where you can tweak this recipe to suit your preferences (and the contents of your pantry) are the filling and the glaze. The ingredients for the dough, however, are non-negotiable.
