Buns, Cinnamon-Quicker

NOTE: Since the filling, dough, and glaze all require melted butter, it’s easier to melt all 10 tablespoons in a liquid measuring cup and divvy it up as needed. Stir the melted butter before each use to redistribute the milk solids. We developed this recipe using a dark cake pan, which produces deeply caramelized buns. If your cake pan is light-colored, adjust the oven rack to the lowest position, heat the oven to 375 degrees, and increase the baking time to 29 to 32 minutes.
