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 - 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 size.
03 - Combine raspberries, sugar, and cornstarch in a small saucepan over medium heat. Cook stirring constantly for 5-7 minutes until thickened to jam-like consistency. Remove from heat and stir in vanilla and cinnamon. Cool completely to room temperature.
04 - Roll risen dough on a lightly floured surface into a 16x12-inch rectangle. Spread cooled raspberry filling evenly over dough, leaving a ½-inch border along edges.
05 - Starting from the long side, roll dough tightly into a log. Using a sharp knife or bench scraper, slice log into 12 equal rolls.
06 - Arrange rolls cut-side up in a greased 9x13-inch baking dish. Cover and let rise in a warm place for 30 minutes until puffy and doubled in size.
07 - Preheat oven to 350°F. Bake rolls for 22-25 minutes until lightly golden brown and centers are fully cooked through.
08 - Whisk powdered sugar, lemon juice, and lemon zest in a small bowl. Add milk 1 tablespoon at a time until glaze reaches pourable consistency.
09 - Drizzle warm lemon glaze generously over freshly baked rolls. Serve warm or at room temperature.
