Classic Black and White Cookie vs Cannelés de Bordeaux: Caramelized Rum and Vanilla Pastries

The Classic Black and White Cookie offers a cake-like, tender crumb finished with dual-toned icing, emphasizing a simple sweetness balanced by rich cocoa. In contrast, the Cannelé relies on a high ratio of egg yolks and rum to produce a deeply caramelized, crisp exterior with a custard-like center. While both utilize butter, sugar, and milk, the cookie uses these for structure and softness, whereas the pastry employs them to achieve a complex, aromatic chew and contrasting textures.
