01 - Combine flour, yeast, sugar, and salt in a large mixing bowl. Whisk warm milk, melted butter, and eggs in a separate bowl. Pour wet mixture into dry ingredients and mix until soft dough forms. Knead by hand or stand mixer for 8–10 minutes until smooth and elastic.
02 - Transfer dough to a greased bowl, cover, and let rise in a warm area for 1 hour until doubled in size.
03 - Combine raspberries, sugar, and cornstarch in a saucepan over medium heat. Cook for 5–7 minutes, stirring constantly until thickened. Remove from heat and stir in vanilla and cinnamon. Cool completely before using.
04 - Roll dough on a floured surface into a 16x12-inch rectangle. Spread cooled raspberry filling evenly over dough, leaving a ½-inch border on edges.
05 - Starting from the long side, roll dough tightly into a log. Cut into 12 equal rolls using a sharp knife or bench scraper.
06 - Arrange rolls in a greased 9x13-inch baking dish. Cover and let rise for 30 minutes until puffy.
07 - Preheat oven to 350°F. Bake rolls for 22–25 minutes until lightly golden and cooked through.
08 - Whisk powdered sugar, lemon juice, lemon zest, and 1 tbsp milk in a bowl. Add additional milk as needed to achieve pourable consistency.
09 - Drizzle lemon glaze generously over warm rolls immediately before serving.
