Pain au chocolat, also known as chocolatine in the south-west part of France and in Canada, or couque au chocolat in Belgium, is a type of viennoiserie sweet pastry consisting of a cuboid-shaped piece of yeast-leavened laminated dough, similar in texture to a puff pastry, with one or two pieces of dark chocolate in the center.
Pain au chocolat is made of the same layered doughs as a croissant. Often sold still hot or warm from the oven, they are commonly sold alongside croissants in French bakeries and supermarkets.
