My Secret to the Perfect Martha Stewart Key Lime Cheesecake
The secret to a great cheesecake is all about the temperature. I always make sure my cream cheese is very soft before starting.
If it is cold, you will get tiny lumps in your batter. Another trick is using real Key limes rather than regular Persian limes.
Key limes are smaller and much more aromatic. They give that authentic Florida flavor that makes this Martha Stewart Key Lime Cheesecake Recipe stand out. Also, do not overmix the eggs; just stir them until combined.

Ingredients You Need for Martha Stewart Key Lime Cheesecake
For the Graham Cracker Crust:
- 1.5 cups graham cracker crumbs
- 1/4 cup granulated sugar
- 6 tablespoons unsalted butter, melted
- 1/2 teaspoon ground cinnamon
For the Cheesecake Filling:
- 24 ounces cream cheese (3 blocks), room temperature
- 1 cup granulated sugar
- 3 large eggs, room temperature
- 1/2 cup fresh Key lime juice
- 1 tablespoon Key lime zest
- 1 teaspoon vanilla extract
- 1/2 cup sour cream

Step-by-Step Guide
1. Prepare the Graham Cracker Crust
Mix the graham cracker crumbs, sugar, and cinnamon in a bowl. Pour in the melted butter and stir well. Press the mixture firmly into the bottom of your springform pan. Bake at 350°F for 10 minutes to set.
2. Beat the Cream Cheese and Sugar
In a large bowl, beat the softened cream cheese until it is very smooth. Gradually add the sugar while continuing to mix. Scrape down the sides of the bowl often. Ensure there are no lumps remaining in the mixture.
3. Add the Eggs One by One
Add the eggs to the cream cheese mixture one at a time. Mix on low speed just until the yellow disappears. Overmixing at this stage can cause cracks in your cheesecake. Keep the batter light and airy.
4. Mix in the Lime and Sour Cream
Stir in the Key lime juice, zest, and vanilla extract. Fold in the sour cream using a rubber spatula. This adds a lovely tang and extra creaminess. The batter should look glossy and smell very fragrant.
5. Bake the Cheesecake
Pour the filling over the pre-baked crust and smooth the top. Bake at 325°F for about 45 to 55 minutes. The edges should be set but the center should still jiggle slightly. Do not overbake the cake.
6. Cool and Chill Properly
Turn off the oven and crack the door open for one hour. This prevents the cake from sinking or cracking. Afterward, let it cool completely on a wire rack. Refrigerate the cheesecake for at least six hours.
Expert Tips & Variations

- Extra Zest: Add more lime zest on top before serving for a beautiful look.
