01 - Combine warm milk, warm water, and yeast in stand mixer bowl. Let stand 5 minutes until foamy. Add sugar, eggs, and melted butter; mix until incorporated.
02 - Gradually add flour and salt. Mix with dough hook on low speed until soft dough forms, about 2 minutes. Knead on medium-low speed for 6-8 minutes until smooth and elastic.
03 - Place dough in lightly greased bowl, turning to coat. Cover with plastic wrap and let rise in warm, draft-free area for 1 to 1.5 hours until doubled in bulk.
04 - Melt butter in saucepan over medium heat. Add brown sugar, cream, honey, and salt. Stir constantly until smooth and bubbling, 2-3 minutes. Pour evenly into greased 9x13-inch baking dish.
05 - Combine brown sugar and Vietnamese cinnamon in small bowl. Mix until thoroughly blended.
06 - Punch down risen dough and turn onto floured surface. Roll into 16x12-inch rectangle. Spread softened butter evenly over surface, leaving 1-inch border. Sprinkle cinnamon-sugar mixture, dates, and nuts over butter.
07 - Starting from long edge, roll dough tightly into log. Pinch seam to seal. Cut into 12 equal slices using sharp knife or unflavored dental floss.
08 - Arrange buns cut-side up in prepared baking dish over glaze. Cover with towel and let rise 30-40 minutes until puffy and nearly doubled.
09 - Preheat oven to 350°F. Bake buns 25-30 minutes until golden brown and centers are fully cooked. Rotate pan halfway through for even browning.
10 - Let buns rest 5 minutes after removing from oven. Carefully invert onto serving platter so glaze coats tops. Serve warm.
