Which dessert at Outback features a combination of key lime and graham cracker crust?

The dessert that features a combination of key lime and graham cracker crust is key lime pie. This classic treat typically consists of a tart and creamy filling made from key lime juice, eggs, and sweetened condensed milk, all resting in a crust made from crushed graham crackers. The combination of the tangy lime flavor and the crunchy, sweet crust creates a well-balanced dessert that is both refreshing and satisfying.

In contrast, the other options, such as chocolate cake, cheesecake, and apple pie, incorporate entirely different flavors and ingredients not associated with key lime or graham crackers. Chocolate cake would focus on rich, chocolatey flavors, while cheesecake is known for its creaminess and often features a graham cracker crust but does not involve key lime. Apple pie, traditionally filled with spiced apples, is distinctly different in ingredients and flavor profile. This highlights the unique nature of key lime pie as the only option that meets the specifics of the question.
