German Cheesecake (Käsekuchen) vs Mille-feuille: Classic French Custard and Puff Pastry

German cheesecake offers a dense, velvety crumb defined by the tangy richness of quark and bright lemon zest, creating a cohesive and sturdy dessert. In contrast, the mille-feuille relies on the architectural contrast between shattering, buttery layers of puff pastry and smooth, vanilla-infused custard. While both utilize milk, sugar, and eggs, the cheesecake integrates these into a unified, baked structure, whereas the mille-feuille highlights the interplay between crisp textures and delicate, cream-based fillings.
