In a medium saucepan, heat milk, butter, and sugar until the butter melts and the mixture reaches 120-130°F (or 105-110°F for active dry yeast). Remove from heat.
02 -
Combine 4 ½ cups of flour, yeast, and salt in the bowl of a stand mixer. Add the milk mixture and mashed bananas, stirring until a shaggy dough forms.
03 -
Knead the dough in a stand mixer with a dough hook for 6-8 minutes, or by hand for 8-10 minutes, until smooth and elastic. Add small amounts of flour if the dough is overly sticky, but do not exceed 5 cups.
04 -
Place the dough in a lightly greased large bowl, turning to coat. Cover and let rise for 1-1 ½ hours, or until doubled in size.
05 -
Turn the dough onto a lightly floured surface and roll into an 18x12 inch rectangle.
06 -
Spread softened butter over the dough, leaving a ½-inch border at the top edge. Mix brown sugar and cinnamon, then sprinkle evenly over the butter. Arrange banana slices on top.
07 -
Roll the dough tightly into a log from the long edge and seal the seam. Using a serrated knife or thread, cut into 12 equal pieces.
08 -
Arrange rolls in a greased 9x13-inch baking dish. Cover and let rise for 45 minutes to 1 hour, or until puffy and nearly doubled.
09 -
Preheat oven to 350°F (177°C). Pour warmed heavy cream over the rolls. Bake for 30-35 minutes, until golden brown. Cool for 20 minutes before frosting.

Beat cream cheese and butter until smooth. Gradually add powdered sugar, mixing until combined. Add vanilla extract and beat on medium-high until fluffy.

Spread frosting over the rolls while still slightly warm.
