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. Whisk thoroughly until well combined. Gradually incorporate 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 damp towel, and let rise in a warm place for 1 hour until doubled in volume.
04 - Toss diced strawberries with cornstarch in a small bowl to coat evenly. Set aside. In a separate bowl, combine brown sugar and ground cinnamon for the cinnamon filling.
05 - Punch down risen dough and roll out into a 16x12-inch rectangle. Spread softened butter evenly over the dough surface. Sprinkle cinnamon sugar mixture across the buttered layer, then distribute prepared strawberries over the top.
06 - Starting from the long edge, roll dough tightly into a log. Using a sharp knife or dough cutter, slice into 12 equal rolls, approximately 1 ¼ inches thick.
07 - Arrange rolls in a greased 9x13-inch baking pan, leaving space for expansion. Cover and let rise for 30-45 minutes until puffy and nearly doubled.
08 - Position oven rack to center position and preheat to 350°F.
09 - Bake rolls for 22-25 minutes until tops are golden brown and filling bubbles visibly. Remove from oven when cooked through.
10 - While rolls bake, beat cream cheese and softened butter until completely smooth and creamy. Add powdered sugar and vanilla extract, mixing until fully incorporated. Drizzle in milk 1 tablespoon at a time until desired pourable consistency is reached.
11 - Let rolls cool in pan for 10-15 minutes. Spread or drizzle cream cheese glaze generously over warm rolls. Serve immediately while still slightly warm.
