Éclair is an oblong pastry made with Pâte à choux filled with cream and topped with icing. Today I made two different types of filling by mixing crème pâtissière with bitter chocolate and instant coffee mixed with alcohol. You can replace bitter chocolate with cacao mass to reduce the sugar and coffee extract. I topped the Éclair with fondant café and fondant chocolat.
The choux dough is baked until it is crisp and hollow inside, which makes the filling possible.
