1. What Is Key Lime Cheesecake?
Key Lime Cheesecake combines two classic desserts: the creamy decadence of traditional cheesecake and the zesty brightness of key lime pie. Unlike a standard lime pie, the cheesecake version offers a rich, velvety filling that complements the tart, citrusy flavor. The buttery crust adds a satisfying crunch, and optional whipped cream topping gives a soft, luxurious finish.
Think of it as a tropical getaway in dessert form — each bite is refreshing, indulgent, and unforgettable.
