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 to incorporate. Gradually add flour, mixing until a soft, workable dough forms.
03 - Turn dough onto a lightly floured surface and knead for 6-8 minutes until smooth and elastic. Transfer to a greased bowl, cover with plastic wrap or a towel, and let rise in a warm place for 1 hour until doubled in size.
04 - Toss diced strawberries with cornstarch in a small bowl until evenly coated. Set aside to allow the cornstarch to activate while you prepare the remaining filling components.
05 - In a separate bowl, combine brown sugar and ground cinnamon until uniformly blended.
06 - Punch down risen dough and roll out into a 16x12-inch rectangle. Spread softened butter evenly over the surface. Sprinkle cinnamon sugar mixture across the dough, then distribute the prepared strawberries over the top.
07 - Starting from the long side, roll dough tightly into a log. Use a sharp knife or dough cutter to slice into 12 equal rolls.
08 - Arrange rolls in a greased 9x13-inch baking pan, leaving space between each. 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 tops are golden brown and filling is bubbling around the edges. Allow to cool slightly in pan before glazing.
11 - Beat softened cream cheese and butter until completely smooth and creamy. Add powdered sugar and vanilla extract, mixing until combined. Drizzle in 2-3 tablespoons milk until glaze reaches desired pourable consistency.
12 - Spread or drizzle the cream cheese glaze over the warm rolls. Serve while still slightly warm for the best texture and flavor.
