01 - Combine warm milk and yeast in a large bowl. Let stand for 5 minutes until the mixture becomes frothy, indicating the yeast is active.
02 - Add melted butter, granulated sugar, egg, and salt to the yeast mixture. Mix thoroughly. Gradually incorporate flour, mixing until a soft, workable dough forms.
03 - Turn dough onto a lightly floured surface. Knead for 6-8 minutes until smooth and elastic. Place in a greased bowl, cover, and let rise for 1 hour until doubled in size.
04 - Toss diced strawberries with cornstarch in a small bowl until evenly coated. Set aside to allow cornstarch to activate.
05 - Combine brown sugar and ground cinnamon in a separate bowl. Mix well to ensure even distribution of cinnamon.
06 - Roll risen dough into a 16x12-inch rectangle. Spread softened butter evenly over surface. Sprinkle cinnamon sugar mixture across dough, then distribute strawberries on top.
07 - Roll dough tightly from the long edge. Cut into 12 equal pieces using a sharp knife or dough cutter.
08 - Arrange 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 for 22-25 minutes until tops are golden brown and filling is bubbling. Allow to cool slightly in pan before glazing.
11 - Beat cream cheese and softened butter until smooth and creamy. Add powdered sugar and vanilla extract; mix until combined. Gradually add milk to achieve desired pouring consistency.
12 - Spread or drizzle glaze over warm rolls. Serve immediately while still warm for best texture and flavor.
