Streuselkuchen (German Crumb Cake) vs Pudin de Pan (Spanish Bread Pudding)

Streuselkuchen relies on a structured, yeast-leavened crumb topping that provides a crisp, buttery contrast to a soft base, while Pudin de Pan emphasizes a dense, custard-soaked interior texture. While both use milk, eggs, and citrus zest for a bright richness, the German cake highlights the structural interplay of flour and fat, whereas the bread pudding utilizes stale bread to soak up aromatics like cinnamon and vanilla. These distinct techniques result in either a refined, textural crumb or a decadent, spoonable comfort dessert.
