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. Whisk until well combined. Gradually incorporate flour, mixing until a soft, sticky dough forms.
03 - Turn dough onto a lightly floured surface and knead for 6-8 minutes until smooth and elastic. Place in a greased bowl, cover with plastic wrap or damp towel, and let rise in a warm area for 1 hour until doubled in size.
04 - Toss diced strawberries with cornstarch in a small bowl until evenly coated. Set aside. In a separate bowl, combine brown sugar and ground cinnamon, mixing thoroughly.
05 - Punch down risen dough and roll out into a 16x12-inch rectangle. Spread softened butter evenly over the surface, leaving a small border. Sprinkle cinnamon sugar mixture across the dough, then distribute prepared strawberries over the top.
06 - Starting from the long edge, roll dough tightly into a log. Use a sharp knife or dough cutter to slice into 12 equal rolls, approximately 1 ¼ inches thick.
07 - Place rolls cut-side up in a greased 9x13-inch baking pan, leaving space between each. Cover and let rise for 30-45 minutes until puffy and nearly doubled.
08 - Preheat oven to 350°F. Bake rolls for 22-25 minutes until tops are golden brown and filling is bubbling around the edges. Remove from oven and let cool in pan for 10-15 minutes.
09 - While rolls cool, beat softened cream cheese and butter until smooth and creamy. Add powdered sugar and vanilla extract, mixing until combined. Gradually drizzle in milk, 1 tablespoon at a time, until desired pouring consistency is reached.
10 - Spread or drizzle the cream cheese glaze generously over warm rolls. Serve immediately while still slightly warm for best texture and flavor.
