01 - In a large bowl, combine flour, instant yeast, sugar, and salt. Whisk until evenly distributed.
02 - Add warm milk, melted butter, eggs, and lemon zest to the dry mixture. Mix thoroughly 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 towel, and let rise in a warm area for 1 hour 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 thickened. Set aside to cool completely.
06 - Punch down risen dough and roll into a 15x10-inch rectangle. Spread cooled blueberry filling evenly over the surface, leaving a small border at the edges.
07 - Starting from the long side, tightly roll the 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 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 until smooth and creamy. Adjust consistency with additional juice if needed.
11 - Drizzle warm lemon glaze over rolls immediately after removing from oven. Serve warm or at room temperature.
