Fry some bananas in butter, then sprinkle them with brown sugar, pour a liqueur over and flambe them.
Perhaps either some banana liqueur, or instead sprinkle the bananas with orange zest (and brown sugar) then pour Gran Marnier over and flambe.
Or did you mean deep fried?

Keep your ice cream very cold/frozen, quickly dip it in batter then more quickly deep fry it.
You could have liqueur over that too.
Maybe even flambe it...
