⅛ teaspoon ground cinnamon, plus additional, for sprinkling
1 ½ cups crushed ice
Directions
Line a small baking sheet or plate with foil.
Peel and slice the banana in half lengthwise and transfer, cut-sides up, to the foil-lined surface.
Sprinkle each side generously with ½ tablespoon turbinado sugar.
Use a blowtorch (or place under a broiler) to evenly caramelize the surface of each banana half. Let cool.
Transfer the bananas to a blender along with the rum, coconut cream, lemon juice, cinnamon, and crushed ice.
Blend until smooth.
Transfer to a chilled glass and garnish with a sprinkle of cinnamon, along with a brûléed banana slice, cinnamon stick, lemon slice, or any other garnishes, as desired.
