Place the water and butter in a heat-proof container and microwave for about 2 minutes. Add the flour. Use a spoon to mix and then microwave for another 30 seconds.
Gradually stir in the beaten egg.
Line a baking tray with parchment paper. Drop the batter onto the tray and shape into long, narrow tubes (if you wet your fingers with water, the batter will be easier to work with).
Bake in a 200°C oven for 25-30 minutes. Once they have finished baking, leave them for 10 minutes to cook slightly with the residual heat.
Once they are removed from the oven, slice them in half. Place whipped cream and fruit on one half and cover with the other half to make a sandwich. Spread melted chocolate over the tops and they're done.
