Step-by-Step key lime cheesecake
1. Preheat the oven to 350°F (175°C). This ensures your cheesecake bakes evenly, creating that perfect creamy texture we all love.
2. Combine graham cracker crumbs, sugar, and melted butter in a mixing bowl. Mix until well combined, creating a sandy texture that will form the base of your crust.
3. Press the mixture firmly into the bottom of a 9-inch springform pan. Make sure it’s evenly spread for a solid foundation for your filling.
4. Bake for 10 minutes, then remove from the oven and let cool. The crust should be lightly golden and fragrant—this is the beginning of something delicious!
For the Filling:
5. Beat the softened cream cheese in a large mixing bowl until smooth. This step is crucial for achieving that velvety consistency in your key lime cheesecake.
6. Add sour cream, sugar, eggs, key lime juice, key lime zest, and vanilla extract. Beat until well combined and smooth—this mixture should be rich and luscious!
Bake the cheesecake:
7. Pour the filling over the cooled crust in the springform pan. Gently spread it out to create an even layer atop your delicious graham cracker base.
8. Place the springform pan in a baking dish filled with water (water bath) to prevent cracking during baking. This helps maintain moisture while ensuring even cooking.
9. Bake for 60 minutes, or until the center is set but slightly jiggly. The edges should look firm while retaining that creamy center you desire.
10. Turn off the oven and let the cheesecake cool in the oven with the door ajar for 1 hour. This gradual cooling process helps avoid cracks on your beautiful dessert!
