Method
 

Preparation
  1. Preheat the oven to 375°F. Lightly grease a 9x13-inch baking pan with cooking spray.
  2. In a large bowl, mix the yellow cake mix, milk, and melted butter until just combined. Fold in the butterscotch chips if using and spread the batter evenly in the prepared pan.
  3. Arrange the banana slices over the batter, overlapping to cover the surface.
  4. In a small bowl, whisk ½ cup brown sugar with ½ cup warm water and cinnamon until dissolved. Pour this mixture evenly over the bananas.
Making the Crumble
  1. In a medium bowl, combine oats, flour, baking powder, chopped walnuts (if using), softened butter, and remaining ¾ cup brown sugar. Mix until coarse crumbs form.
  2. Evenly sprinkle the oat crumble over the banana layer without pressing it down.
Baking
  1. Bake for 40–45 minutes, or until the top is golden brown and the center is bubbly. If browning too quickly, tent with foil.
  2. Remove from oven and let cool for about 20 minutes before serving warm with ice cream and extra banana slices.

Notes

Serve warm for the best experience. Can be made ahead by assembling up to the crumble stage and refrigerating for up to 24 hours.
