01 - Combine warm milk and yeast in a large bowl. Let stand for 5 minutes until mixture becomes frothy, indicating yeast activation.
02 - Add melted butter, granulated sugar, egg, and salt to the yeast mixture. Mix thoroughly until ingredients are well incorporated.
03 - Gradually add flour while mixing to form a soft, slightly sticky dough. Mix until all flour is absorbed and dough begins to pull away from sides of bowl.
04 - Turn dough onto a lightly floured surface and knead for 6-8 minutes until smooth and elastic. Place dough in a greased bowl, cover with plastic wrap or towel, and let rise for 1 hour until doubled in size.
05 - Toss diced strawberries with cornstarch in a small bowl until evenly coated. Set aside to allow cornstarch to activate.
06 - Combine brown sugar and ground cinnamon in a separate bowl, mixing until uniform.
07 - Roll out risen dough into a 16x12-inch rectangle on a lightly floured surface. Spread softened butter evenly over the dough surface.
08 - Sprinkle cinnamon sugar mixture evenly over buttered dough, then distribute cornstarch-coated strawberries across the surface.
09 - Starting from the long edge, roll dough tightly into a log. Cut into 12 equal pieces using a sharp knife or dough cutter.
10 - Place rolls in a greased 9x13-inch baking pan, leaving space between each. Cover and let rise for 30-45 minutes until puffy.
11 - Preheat oven to 350°F during the final rise time.
12 - Bake rolls for 22-25 minutes until tops are golden brown and filling is bubbling. Remove from oven and let cool for 10 minutes.
13 - Beat softened cream cheese and butter until smooth and creamy. Add powdered sugar and vanilla extract, mixing until combined.
14 - Add milk 1 tablespoon at a time until glaze reaches desired pourable consistency.
15 - Spread or drizzle glaze over warm rolls. Serve immediately while still slightly warm.
