01 - Combine warm milk and yeast in a large bowl. Let stand for 5 minutes until mixture becomes frothy.
02 - Add melted butter, sugar, egg, and salt to the yeast mixture. Mix thoroughly. Gradually incorporate flour, mixing until a soft, workable dough forms.
03 - Knead dough on a lightly floured surface for 6-8 minutes until smooth and elastic. Transfer to a greased bowl, cover with plastic wrap, and let rise for 1 hour until doubled in volume.
04 - Toss diced strawberries with cornstarch in a small bowl until evenly coated. Set aside.
05 - Combine brown sugar and ground cinnamon in a separate bowl. Mix until uniformly blended.
06 - Roll out risen dough into a 16x12-inch rectangle. Spread softened butter evenly over the surface. Sprinkle cinnamon sugar mixture across the dough, then distribute strawberries on top.
07 - Roll dough tightly from the long edge. Slice into 12 equal portions using a sharp knife or dough cutter.
08 - Place rolls in a greased 9x13-inch baking pan. Cover and let rise for 30-45 minutes until puffy and nearly doubled.
09 - Preheat oven to 350°F.
10 - Bake rolls for 22-25 minutes until golden brown and filling bubbles visibly around the edges. Allow to cool slightly in pan.
11 - Beat cream cheese and butter until completely smooth. Add powdered sugar and vanilla extract, mixing until combined. Gradually add milk until desired consistency is reached.
12 - Spread glaze generously over warm rolls. Serve immediately while still slightly warm.
