Blitz Kuchen, a traditional German “lightning cake,” is beloved for its speed and simplicity. This variation, adapted as a coffee cake, reflects mid-century American kitchens blending German roots with cozy, cinnamon-topped sweetness. Perfect for weekend mornings or impromptu guests, its name ("blitz") reflects how quickly it comes together. The crumbly topping, cinnamon warmth, and nutty crunch create a nostalgic and comforting flavor that makes it a cherished staple.
