Streuselkuchen (German Crumb Cake) vs Classic St. Louis Gooey Butter Cake

Streuselkuchen relies on a yeast-leavened dough topped with buttery crumbs and bright lemon zest, offering a structured, textured bite. In contrast, St. Louis Gooey Butter Cake utilizes a dense, custard-like base enriched with cream cheese, vanilla, and a dusting of powdered sugar for a decadent, melt-in-the-mouth consistency. While both cakes build on a shared foundation of butter, sugar, milk, and eggs, the former emphasizes a crisp crumb contrast, whereas the latter prioritizes a soft, uniform richness that leans into its cream-based profile.
