This Key Lime Cheesecake is creamy, tangy, and downright dreamy; the kind of dessert that feels special from the first bite. The graham cracker crust is buttery and crisp, while the filling is silky-smooth with bright citrus pop from real key lime juice and fresh zest. It’s perfectly balanced; rich without being heavy, sweet with just enough tartness to keep you coming back for another forkful.
This is a dessert I make when I want something that truly impresses without complicated techniques. The slow bake and gentle cooling keep the texture luscious and help prevent cracks, and letting it chill overnight makes slicing effortless. I’ve served this for holidays and celebrations, and it never fails to disappear quickly. A little whipped cream on top is all it needs.
If you love classic cheesecake with a fresh, summery twist, this one is a must-make. Love this recipe? Pin it to your Cheesecake Favorites board on Pinterest so you don’t lose it.

kcalA smooth, tangy key lime cheesecake with a buttery graham cracker crust.
Ingredients
2 cups graham cracker crumbs
½ cup unsalted butter, melted
32 oz cream cheese, softened
1¼ cups granulated sugar
1 tbsp cornstarch
4 large eggs
1 tbsp lime zest, finely grated
⅔ cup key lime juice
Directions
- Preheat the oven to 150°C / 300°F.
- In a small bowl, mix the graham cracker crumbs and melted butter until evenly moistened. Press firmly into the bottom and partially up the sides of a springform pan. Refrigerate for at least 1 hour to set.
- In a large bowl, beat the cream cheese, sugar, lime zest, and cornstarch with an electric mixer until smooth and fluffy.
- Beat in the eggs one at a time, mixing just until blended after each addition.
- Add the key lime juice and gently finish mixing by hand. Do not overmix.
- Pour the filling into the chilled crust. Place a shallow pan of water on the lower oven rack to create steam.
- Bake for 55 to 60 minutes, until the center is just set.
- Turn off the oven and let the cheesecake rest inside with the door cracked open about 10 cm / 4 inches for 30 minutes.
- Remove from the oven and cool at room temperature for 30 minutes. Cover and refrigerate overnight.
- Before serving, run a warm knife around the edge, release the springform, and slice. Serve with whipped cream if desired.
Cooking Notes
- Room-temperature cream cheese ensures a smooth batter.

Recipe Science
Cheesecake texture depends on gentle protein coagulation. Baking at a low temperature allows egg proteins to set slowly, producing a smooth, custard-like structure. Cornstarch stabilizes the batter, reducing the risk of cracking and helping the cheesecake slice cleanly once chilled.
Steam from the water pan moderates oven heat and prevents rapid moisture loss at the surface. The gradual cooling phase further reduces contraction, which is the primary cause of cracks in baked cheesecakes.
Saturated fat and added sugars are High (over 20% DV per slice). Smaller slices and fresh fruit toppings help balance indulgence.
