01 - Combine flour, instant yeast, sugar, and salt in a large mixing bowl.
02 - Add warm milk, melted butter, eggs, and lemon zest to the dry ingredients. Mix until a cohesive dough forms.
03 - Turn dough onto a floured surface and knead for 8-10 minutes until smooth and elastic.
04 - Place dough in a greased bowl, cover with plastic wrap or a clean towel, and let rise in a warm, draft-free area for 1 hour or until doubled in size.
05 - Combine blueberries, sugar, lemon juice, cornstarch, and lemon zest in a small saucepan. Cook over medium heat for 2-3 minutes, stirring constantly, until mixture thickens. Remove from heat and cool completely.
06 - Roll risen dough into a 15x10-inch rectangle. Spread cooled blueberry filling evenly over the surface, leaving a small border around the edges.
07 - Starting from a long side, tightly roll up the dough. Use a sharp knife to slice the log into 12 equal rolls.
08 - Arrange rolls in a greased 9x13-inch baking dish, leaving space between each. Cover and let rise for 30 minutes until puffy.
09 - Preheat oven to 350°F. Bake rolls for 22-25 minutes until golden brown and cooked through.
10 - Whisk together powdered sugar, lemon juice, and melted butter in a small bowl until smooth and creamy.
11 - Drizzle lemon glaze over warm rolls immediately before serving.
