This coffee crumb cake is a delightful twist on the classic! The tangy depth of the sourdough starter adds a unique, slightly tart flavor to the soft, moist cake base, balancing beautifully with the rich, cinnamon-sugar streusel topping. The crumbly topping offers a satisfying crunch, perfectly complementing the cake’s tender crumb. It's the kind of cake that pairs perfectly with a cup of coffee, offering layers of flavor in every bite
