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, slightly sticky dough forms.
03 - Turn dough onto a lightly floured surface. Knead for 6-8 minutes until smooth and elastic. Place in a greased bowl, cover with plastic wrap, 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, mix brown sugar and cinnamon until thoroughly combined.
05 - Roll risen dough into a 16x12-inch rectangle. Spread softened butter evenly over the surface. Sprinkle cinnamon sugar mixture across the dough, then distribute cornstarch-coated strawberries over the top.
06 - Starting from the long edge, roll dough tightly into a log. Cut into 12 equal pieces using a sharp knife or dough cutter.
07 - Place 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.
08 - Preheat oven to 350°F. Bake rolls for 22-25 minutes until golden brown on top and filling is bubbling around the edges. Allow to cool in pan for 10 minutes.
09 - While rolls cool, beat cream cheese and softened butter until smooth and creamy. Add powdered sugar and vanilla extract, mixing until combined. Gradually stir in milk until glaze reaches desired pourable consistency.
10 - Spread warm glaze evenly over slightly cooled rolls. Serve immediately while still warm for best texture and flavor.
