Chef John's Bananas Foster

Step 1
Heat butter and brown sugar in a skillet over medium-high heat until butter melts and mixture begins to bubble, 3 to 5 minutes.

Step 2
Place bananas, cut-side down, into the brown sugar mixture. Cook until just golden, about 30 seconds; flip and cook until golden on the other side, about 30 seconds. Turn off the heat.

Step 3
With the heat off, pour rum and banana liqueur into the skillet. Turn the heat to medium-high or high; cook until alcohol ignites and flames, 1 to 3 minutes. Carefully add cinnamon. When the flames die, remove from the heat.

Step 4
Scoop vanilla ice cream into two bowls. Divide banana mixture between the bowls and garnish with mint sprigs.
