Heat up the milk, butter, and sugar in a medium pot until the butter is melted and the liquid hits 120–130°F (105–110°F if you're using active dry yeast). Take off the heat and let it cool a little.
02 -
In a stand mixer's bowl, use the paddle attachment to mix up 4 ½ cups of flour, salt, and yeast. Add the lukewarm butter mixture and mashed banana, stirring until it starts to look like a rough dough.
03 -
Switch to the dough hook and knead on medium speed for about 6-8 minutes, adding a bit more flour if needed (up to a total of 5 cups). The dough should be smooth with a slight stickiness. If you’re doing it by hand, knead on a floured surface for 8–10 minutes.
04 -
Grease a large bowl lightly, pop the dough inside, and cover it up. Let it rest in a warm, draft-free spot for about 1–1.5 hours (or longer for active dry yeast) until it’s doubled in size.
05 -
Sprinkle some flour on your work surface and roll the dough into a rectangle about 18×12 inches.
06 -
Using a knife or spatula, smear the soft butter over the dough but leave about ½-inch border at the top. Stir together the brown sugar with cinnamon and scatter it everywhere on the butter. Lay the thin banana slices on top.
07 -
Start rolling the dough tightly from the long edge into a log. Seal the seam by pinching it closed. Slice the log into 12 equal-sized rolls with thread, unflavored floss, or a serrated knife for clean edges.
08 -
Place the rolls, spiral sides facing up, into a greased 9×13 inch dish. Cover them and let them puff up for 45 minutes (or 75 minutes if using slower yeast).
09 -
Set your oven to 350°F (177°C). Drizzle the slightly warmed heavy cream over the rolls and bake for 30–35 minutes until beautifully golden. Let them cool for 20 minutes before slathering them with frosting.

Beat the softened cream cheese and butter together until smooth and creamy. Add the powdered sugar slowly, mixing the whole time. Stir in the vanilla extract, then spread it on the rolls while they're still a bit warm.
