Key lime crunch cake is a tropical-inspired dessert that combines bold citrus flavor with irresistible texture. This moist, tangy cake is infused with real key lime juice and zest, offering a refreshing burst of flavor in every bite. What sets it apart is the crunchy topping—often made from crushed graham crackers, cookies, or buttery crumble—that adds a satisfying contrast to the soft, tender cake. Finished with a light lime glaze or creamy frosting, it's a zesty, crowd-pleasing treat perfect for summer gatherings and citrus lovers alike.
