Switch to the dough hook and knead on medium speed for 6-8 minutes, adding additional flour if dough is overly sticky (do not exceed 600 g total). Alternatively, knead by hand on a lightly floured surface for 8-10 minutes until dough is smooth, slightly sticky, and elastic.

Lightly grease a large bowl and transfer dough to it, turning once to coat. Cover and allow to rise in a warm area until doubled in size, approximately 60-90 minutes.

On a lightly floured surface, roll the dough into a rectangle measuring 46 x 30 cm.

Spread the dough surface evenly with softened butter, leaving a 1.5 cm border along the top long edge. In a small bowl, combine brown sugar and cinnamon, then sprinkle over the butter. Press lightly to adhere. Evenly distribute banana slices on top.

Starting with the long edge, tightly roll the dough into a log. Pinch to seal the seam. Slice the log into 12 equal portions using a serrated knife or unflavored dental floss for clean cuts.

Arrange rolls spiral side up in a generously greased 23 x 33 cm baking dish. Cover and let rise in a warm, draft-free place until puffy and nearly doubled, about 45 minutes.
