1-First Step: Prepare the dough – Mise en place Warm the milk to 110°F; too hot kills yeast. In a large bowl, whisk 3 cups flour, 1/4 cup sugar, 1 tsp salt, and 2 1/4 tsp yeast. Add warm milk, 1/4 cup melted butter, and 1 egg. Stir until a shaggy dough forms. Turn onto a floured surface and knead 8-10 minutes until smooth and elastic. It should pull away from the bowl cleanly. Place in a greased bowl, cover with a damp cloth, and let rise in a warm spot for 1 hour until doubled.

2-Second Step: Make the raspberry filling While dough rises, chop 1/2 cup fresh raspberries if using. Mix 1 cup raspberry jam with 1/4 cup brown sugar for a spreadable paste. Set aside. This combo ensures the filling stays juicy without leaking too much during baking. Pro tip: Chill jam slightly for easier spreading.

3-Third Step: Roll and fill the dough Punch down risen dough. Roll into a 12×16-inch rectangle on a lightly floured surface, about 1/4-inch thick. Evenly spread raspberry filling, leaving a 1-inch border on one long edge. Sprinkle chopped raspberries over jam. Roll tightly from the long side into a log, pinching seam to seal. Use dental floss or a sharp knife to slice into 12 equal pieces, each about 1.5 inches thick.

4-Fourth Step: Second rise Grease a 9×13-inch pan. Place slices cut-side up, spaced apart for rising. Cover loosely and let rise 30-45 minutes until puffy. Preheat oven to 375°F (190°C) during this time.

5-Fifth Step: Bake the sweet raspberry buns Bake at 375°F for 20-25 minutes until tops are golden brown and internal temp hits 190°F. Cover with foil after 15 minutes if browning fast. High altitude: Drop to 350°F and add 2-3 minutes. Fresh from the oven, they pull apart with juicy centers. Let cool 10 minutes in pan.

6-Final Step: Glaze and serve Whisk 1 cup powdered sugar, 2-3 tbsp milk, and 1/2 tsp vanilla until smooth. Drizzle over warm buns. Brush tops with melted butter for shine. Serve warm for best texture. Pairs great with coffee or tea. Inspired by recipes like this raspberry swirl sweet rolls version. Store leftovers properly to enjoy later.
