01 - Combine warm milk and yeast in a large bowl. Let stand for 5 minutes until 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, cohesive 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 or a towel, and let rise for 1 hour or until doubled in volume.
04 - Toss diced strawberries with cornstarch in a small bowl until evenly coated. Set aside to allow cornstarch to absorb moisture while preparing other components.
05 - Combine brown sugar and ground cinnamon in a separate bowl, stirring until thoroughly blended.
06 - Roll risen dough into a 16x12-inch rectangle on a lightly floured surface. Spread softened butter evenly over the dough surface. Sprinkle cinnamon sugar mixture across the buttered dough, then distribute the cornstarch-coated strawberries on top.
07 - Roll dough tightly from the long edge to form a log. Cut into 12 equal portions using a sharp knife or dough cutter.
08 - Arrange rolls in a greased 9x13-inch baking pan, leaving slight space between each. Cover and let rise for 30-45 minutes until puffy and nearly doubled.
09 - Preheat oven to 350°F while rolls complete their second rise.
10 - Bake rolls for 22–25 minutes until tops are golden brown and filling is bubbling around the edges. Cool in pan for 10 minutes before glazing.
11 - Beat softened cream cheese and butter together until completely smooth and no lumps remain. Add powdered sugar and vanilla extract, mixing until creamy. Drizzle in milk 1 tablespoon at a time until desired spreading consistency is reached.
12 - Spread cream cheese glaze generously over warm rolls. Serve immediately while still slightly warm for the best texture and flavor experience.
