In a large bowl or bowl of a stand mixer fixed with paddle attachment, whisk yeast with 1/4 cup warm water. Let stand 5 minutes.

Stir in milk, molasses, brown sugar, egg, oil and salt. Stir in 1 cup flour, then replace paddle attachment with dough hook. Add enough flour until dough pulls away from sides of the bowl (you may not use all the flour). Increase speed to medium and knead for 5 minutes, adding 1 tablespoon flour at a time as necessary until you end up with a smooth, elastic dough (you can also knead by hand on a lightly floured surface for 10 minutes until you end up with a smooth, elastic dough). Shape dough into a ball and place in a large, lightly greased bowl, cover with plastic wrap and let rise until doubled, about 1 hour.

Punch risen dough down and place on a lightly floured surface. Cover and let rest 10 minutes.

Grease a 13-by-9-inch pan and set aside. In a small bowl, whisk together brown sugar, sugar, cinnamon and ginger. Roll dough out into a 12-by-8-inch rectangle and brush melted butter on top of dough. Sprinkle evenly with brown sugar mixture and roll up tightly from the long end, pinching to seal. Cut log into 12 equal pieces and space evenly in 13-by-9-inch pan. Cover and let rise until doubled, about 45 minutes.

Preheat oven to 350 degrees F. Uncover risen rolls and bake 20-25 minutes until puffed and golden brown. In the meantime, make your glaze: Whisk together powdered sugar, cinnamon, vanilla extract and enough milk to make a drippy glaze. Remove rolls from oven and let cool 5 minutes before drizzling with glaze. Top with frozen cranberries rolled in sugar and serve warm.
