Fried vanilla ice.
Make a nice ball of vanilla ice, dip it in egg-white (well stirred one) than in to smashed hazelnuts and grinded cornflakes. back in the egg-white and again back in the smashed hazelnuts. Put it in to a very good freezer until it's completely frozen. (you could repeat the previous step)
prepare some caramel sauce. caster sugar caramelise butter in at last moment to cool it down. (or some recipe with cream)
Get the deep fryer at 175 degrees Celsius throw the vanilla balls in until done (15-20 sec). If the fryer is too small increase the temperature, because once you drop it in the temperature will drop.

P.s the idea is of course to fry the outside and not the inside
And be a bit careful you don't overcook because pure liquid in the fryer is the very last thing you want.
