Cut figs in half lengthways and brush with a little oil. Grill on the cut side over a hot part of the barbecue or in a heavy skillet until dark golden in colour (they will stick a little to the grill). Turn over and cook on the other side for about 1 minute.
While they’re cooking, toast the cake on the barbecue or under a grill on both sides.
To serve, place a slice of cake on a plate, scoop some ice cream on, top with figs and dust with a little icing sugar, for that special ‘new-fallen snow’ effect!
