Pain au chocolat, also known as chocolatine in the south-west part of France and in French speaking parts of Canada, or couque au chocolat in Belgium, is a type of Viennoiserie 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. The chocolate usually has a slight bite to the texture.

Pastry is baked food made with a dough of flour, water, and shortening that may be savoury or sweetened. Sweetened pastries are often described as bakers' confectionery. The word "pastries" suggests many kinds of baked products made from ingredients such as flour, sugar, milk, butter, shortening, baking powder, and eggs. Small tarts and other sweet baked products are called pastries as a synecdoche. Common pastry dishes include pies, tarts, quiches, croissants, and pasties.
