01 - In a large mixing bowl, combine flour, instant yeast, sugar, and salt. Whisk together until evenly distributed.
02 - Pour warm milk, melted butter, eggs, and lemon zest into the dry ingredients. Mix thoroughly until a cohesive dough forms.
03 - Turn dough onto a lightly floured surface. Knead for 8-10 minutes until smooth, elastic, and no longer sticky.
04 - Place dough in a greased bowl, cover with plastic wrap or a clean towel. Let rise in a warm, draft-free area for 1 hour until doubled in volume.
05 - Combine blueberries, sugar, lemon juice, cornstarch, and lemon zest in a small saucepan. Cook over medium heat, stirring constantly for 2-3 minutes until mixture thickens. Remove from heat and let cool completely.
06 - Punch down risen dough and roll into a 15x10-inch rectangle. Spread cooled blueberry filling evenly across the surface, leaving a small border around edges.
07 - Starting from the long side, tightly roll dough into a log. Use a sharp knife or dental floss to slice into 12 equal rolls.
08 - Arrange rolls in a greased 9x13-inch baking dish. Cover and let rise in a warm place for 30 minutes until puffy.
09 - Preheat oven to 350°F. Bake rolls for 22-25 minutes until golden brown and cooked through.
10 - While rolls bake, whisk powdered sugar, lemon juice, and melted butter in a small bowl until smooth and creamy.
11 - Drizzle warm lemon glaze over rolls immediately after removing from oven. Serve warm or at room temperature.
