What dessert is known for its layers and coffee flavor?

The dessert recognized for its layers and coffee flavor is Tiramisu. This traditional Italian dessert is crafted with alternating layers of coffee-soaked ladyfingers (savoiardi) and a rich mixture of mascarpone cheese, eggs, sugar, and cocoa powder. The coffee flavor is a defining characteristic, often enhanced by the addition of espresso or coffee liqueur, which sets it apart from other desserts. Additionally, the textural contrast between the creamy filling and the airy ladyfingers creates a delightful experience.

In contrast, chocolate cake, while delicious and potentially layered, does not typically highlight coffee flavor as a primary component. An ice cream sundae primarily consists of ice cream with various toppings and lacks the layered structure typical of Tiramisu. Panna cotta, although a layered dessert, is primarily based on a creamy custard without the coffee flavor associated with Tiramisu. Hence, Tiramisu is distinct in both its layered composition and its prominent coffee notes, making it the correct answer.
