Pain au chocolat also called a chocolatine in South-West France and in French Canada, is a French pastry, consisting of a cuboid-shaped piece of yeast-leavened laminated dough similar to puff pastry, containing strips of chocolate. In France, they are often sold still hot or at least warm from the oven.
Translated literally as 'chocolate bread', it is fundamentally a croissant variation and is commonly sold alongside croissants in French bakeries and supermarkets.
In Germany, Belgium, Ireland and the United Kingdom they are sold in most bakeries and supermarkets.
