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, sugar, egg, and salt to the yeast mixture. Mix thoroughly to combine. 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. Place in a greased bowl, cover with plastic wrap or a towel, and let rise for 1 hour until doubled in volume.
04 - Toss diced strawberries with cornstarch in a small bowl until evenly coated. Set aside to allow cornstarch to activate 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. Spread softened butter evenly across the surface. Sprinkle cinnamon sugar mixture over butter, then distribute strawberries atop the filling.
07 - Starting from the long edge, roll dough tightly into a log. Cut into 12 equal portions using a sharp knife or dental floss for clean slices.
08 - Place rolls cut-side up in a greased 9x13-inch baking pan. 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 bubbly. Remove from oven and allow to cool slightly in pan.
11 - Beat cream cheese and softened butter until smooth and creamy. Add powdered sugar and vanilla extract, mixing until combined. Gradually add milk, 1 tablespoon at a time, until desired drizzling consistency is reached.
12 - Spread or drizzle glaze over warm rolls. Serve immediately while still slightly warm for the best texture and flavor.
