Éclair Mountain - Long Custard-Filled French Dessert Doughnut

An éclair is a long, thin pastry made with choux pastry filled with a cream and topped with icing. The dough, which is the same as that used for profiterole, is piped into an oblong shape with a pastry bag and baked until it is crisp and hollow inside. Once cool, the pastry then is filled with a coffee- or chocolate-flavoured pastry cream and topped with fondant icing of the same flavour as the filling.
