01 - Combine flour, yeast, sugar, and salt in a large mixing bowl. Whisk warm milk, melted butter, and eggs separately, then add to dry ingredients. Mix until soft dough forms, then knead by hand or stand mixer for 8–10 minutes until smooth and elastic.
02 - Place dough in a greased bowl, cover with plastic wrap or towel, and let rise in a warm draft-free area for 1 hour until doubled in volume.
03 - Combine raspberries, sugar, and cornstarch in a small saucepan over medium heat. Cook for 5–7 minutes, stirring constantly until thickened to jam consistency. Remove from heat, stir in vanilla and cinnamon, and cool completely before using.
04 - Roll dough on a lightly floured surface into a 16x12-inch rectangle. Spread cooled raspberry filling evenly over surface, leaving a ½-inch border around edges.
05 - Starting from the long side, roll dough tightly into a log. Use sharp knife or bench scraper to cut into 12 equal rolls.
06 - Arrange rolls in a greased 9x13-inch baking dish. Cover and let rise for 30 minutes until puffy and nearly doubled.
07 - Preheat oven to 350°F. Bake rolls for 22–25 minutes until lightly golden and centers are cooked through.
08 - Whisk powdered sugar, lemon juice, and lemon zest in a bowl. Add milk gradually, 1 tablespoon at a time, until pourable consistency is achieved.
09 - Drizzle glaze generously over warm rolls immediately before serving. Best enjoyed while warm.
