What are the classical and contemporary examples of croissant?

Classical examples of Croissants include the traditional buttery, flaky pastry made from layered yeast-leavened dough, often enjoyed plain or filled with almond paste. Contemporary variations have expanded to include creative flavors and fillings such as chocolate, ham and cheese, or even matcha and savory options. Additionally, some modern bakeries experiment with unique shapes and textures, blending croissant dough with other pastry styles, like cruffins or croissant-doughnuts. These innovations showcase the versatility and enduring popularity of the croissant in both classic and modern culinary contexts.
