01 - Combine warm milk and yeast in a large bowl. Let stand for 5 minutes until the mixture becomes foamy, indicating the yeast is active.
02 - Whisk sugar, melted butter, eggs, and salt into the yeast mixture. Gradually incorporate flour, stirring until a sticky dough forms that pulls away from the sides of the bowl.
03 - Turn dough onto a lightly floured surface and knead for 7–8 minutes until smooth and elastic. Transfer to a greased bowl, cover with plastic wrap, and let rise in a warm, draft-free area until doubled in volume, approximately 1 to 1.5 hours.
04 - Melt butter in a saucepan over medium heat. Stir in brown sugar, honey, heavy cream, and salt. Cook for 2–3 minutes, stirring constantly until smooth and bubbling. Pour the glaze evenly into a 9x13 inch baking dish.
05 - Combine brown sugar and Vietnamese cinnamon in a small bowl, mixing thoroughly to distribute the spice evenly.
06 - Punch down the risen dough and roll out on a floured surface into a 12x16 inch rectangle. Spread softened butter evenly over the surface, leaving a 1-inch border. Sprinkle the cinnamon sugar mixture over the butter, then scatter chopped dates across the filling.
07 - Starting from the long edge, roll the dough tightly into a log. Using a sharp knife or bench scraper, cut the log into 12 equal portions, approximately 1 1/2 inches thick.
08 - Place the buns cut-side up in the prepared baking dish, arranging them evenly. Cover with a towel and let rise in a warm place for 45 minutes until puffy and noticeably expanded.
09 - Preheat oven to 350°F. Bake the buns for 28–32 minutes until deep golden brown and the filling is bubbling around the edges. The internal temperature should reach 190°F when fully baked.
10 - Allow the buns to cool in the pan for exactly 5 minutes. Carefully invert onto a serving platter so the sticky glaze coats the top. Serve immediately while warm for the best texture and flavor.
