Bloom the yeast: whisk the warm milk, 1 teaspoon sugar, and yeast in a small bowl. Let rest 5–10 minutes until foamy and fragrant.
Make the dough: in a mixing bowl, combine the melted butter, remaining sugar, egg, and salt. Stir in the foamy yeast mixture. Add 2 cups of the flour and mix until shaggy; the batter will be sticky.
Knead: turn dough onto a lightly floured surface and knead, adding the remaining flour a little at a time, until smooth, elastic, and slightly tacky—about 8–10 minutes by hand or 5–6 minutes in a stand mixer with a dough hook.
First rise: place dough in a lightly oiled bowl, cover, and let rise in a warm spot until doubled—about 1 to 1 1/2 hours.
Prepare the cranberry filling: in a small saucepan combine chopped cranberries, brown sugar, orange juice, zest, and cornstarch. Cook over medium heat, stirring often, until berries soften and mixture thickens—about 6–8 minutes. Cool to room temperature.
Roll and fill: roll the risen dough into a 12×16-inch rectangle (about 1/4-inch thick). Spread the cooled cranberry filling evenly over the dough, leaving a 1/2-inch border.
Roll up: starting from the long edge, roll the dough into a tight log, pinch the seam to seal, trim ends, and cut into 9–12 equal rolls (2–2.5 inches each) using a sharp knife or dental floss.
Second rise: place rolls in a greased 9×13-inch pan (or two smaller pans), cover loosely, and let rise until puffy and nearly doubled—about 30–45 minutes.
Bake: preheat oven to 350°F (175°C). Bake rolls for 22–28 minutes until golden-brown and centers register about 190°F. Tent with foil if tops brown too quickly.
Glaze and finish: let rolls cool 10–15 minutes. Whisk powdered sugar, 2–3 tablespoons orange juice, and vanilla until smooth and pourable. Drizzle over warm (not piping hot) rolls so glaze spreads into spirals.
Serve: enjoy warm. Store baked rolls in an airtight container at room temperature up to 2 days or refrigerate up to 5 days; reheat gently before serving.
Notes
Pillowy cranberry orange sweet rolls with a tart-sweet cranberry ribbon and orange-scented glaze — a cozy brunch or breakfast bake that yields glossy, spiral rolls.
