Prepare the banana bread according to the recipe WITHOUT nuts.
Caramel Sauce: add the caramel sauce, 1 tablespoon of butter, cinnamon and pecans to a medium saucepan.
Bring to a boil then reduce the heat and simmer 5-7 minutes until it reduces slightly and thickens. NOTE: can be made a day ahead and refrigerated.
Before serving: In a large skillet, melt 2 tablespoons of butter or enough to coat the bottom of the skillet.
Cut the banana bread into 1/2" slices then add it to the skillet over medium to medium-high heat (½ to 1 slice per person).
Slice the bananas and add to the skillet searing both sides of the bread and bananas. Remove from the skillet and cool to room temp.
Lay 1/2 or 1 full slice of banana bread on a plate. Top with a scoop of ice cream, Rum Caramel Sauce, and garnish with caramelized bananas. Optional: dust with powdered sugar.
