Choconana & Ice Cream

Was watching a 2008 repeat of UK Masterchef. This was the winner's dessert which I think probably helped him win. Need to make this soon! Although I don't go into the recipe for the cake and ice cream, I'm reminding myself of the final step of preparing the bananas here.

chocolate moelleux
home-made vanilla ice cream
4 firm but ripe bananas
2 tblsp butter, melted
2 tblsp brown sugar
2 tblsp of rum

1. prepare chocolate moelleux
2. prepare ice cream
3. when above are ready, combine sugar and butter in a shallow dish
4. peel the bananas, cut in half lengthwise, and then again crosswise 
5. saute bananas around a minute, add a bit of rum and flambe before serving
