Mastering the Instant Pot Key Lime Cheesecake
Cheesecake holds a special place in my heart, ranking high on my list of all-time favorite desserts, right alongside a perfectly flaky pie and a freshly baked donut.

Essential Tips for a Flawless Instant Pot Cheesecake
While making cheesecake might seem daunting to some, I firmly believe that preparing one in a pressure cooker is significantly easier and yields more consistent results than baking in a conventional oven. With a few key tips, you’ll be creating stunning, crack-free cheesecakes with minimal fuss.
- **Room Temperature Ingredients are Non-Negotiable:** This is arguably the most crucial step for achieving a perfectly smooth and uniform cheesecake batter. Cream cheese, eggs, and any dairy should be at room temperature. Cold ingredients don’t emulsify properly, leading to lumps and an uneven texture in your final cheesecake. Plan ahead and take your ingredients out of the refrigerator at least an hour before you begin mixing.
- **Mind the Crust Height:** When pressing your graham cracker crust into the springform pan, ensure it doesn’t extend too far up the sides – ideally, no more than an inch. The reason for this precision is simple: if the crust is exposed above the cheesecake batter line, it can absorb water during the pressure cooking process, resulting in a soggy, gummy texture that detracts from the overall experience. A low crust ensures a crisp base.
- **Avoid Overmixing the Batter (Especially After Adding Eggs):** Once you’ve incorporated the eggs into your cheesecake batter, resist the urge to overmix. Overmixing introduces too much air into the batter, which can cause the cheesecake to puff up excessively during cooking and then crack as it cools. Mix just until the ingredients are combined and no streaks of egg remain. A gentle hand leads to a dense, creamy texture.
- **The Indispensable Sling:** You will absolutely need a sling to safely lower your cheesecake into the Instant Pot and, more importantly, to remove it without incident once cooked. While you can purchase a dedicated silicone sling designed for pressure cookers (like this one), a homemade foil sling works just as effectively. Simply fold a sturdy 26×4-inch piece of heavy-duty aluminum foil lengthwise multiple times to create a strong, narrow band. Use this to cradle your springform pan and gently lower it onto the trivet. Even if your Instant Pot trivet has handles, a foil sling provides better stability and makes removal much easier, preventing spills and burns.

Key Lime vs. Regular Lime: Your Juice Substitution Guide
A common question arises when tackling a Key Lime Cheesecake: are true key limes absolutely essential, or can regular limes be used as a substitute? The answer lies in understanding the subtle, yet distinct, differences between these two citrus varieties. Key limes, often smaller and yellowish when ripe, are known for their more aromatic, tarter, and intensely floral flavor. They also tend to be more acidic and have thinner skins, making them a bit more challenging to juice in large quantities. Persian limes, the larger, dark green limes commonly found in most grocery stores, are less acidic, have a milder flavor, and are much easier to juice. While the unique essence of key limes contributes to the authentic taste of this cheesecake, their availability can be limited, and they often come at a higher price point, requiring more effort to extract their precious juice.
If you find yourself without key limes, or simply prefer a more convenient option, don’t fret! The authors of “Instantly Sweet” offer an excellent and widely accepted substitution. They recommend using a blend of 3 tablespoons of freshly squeezed Persian lime juice combined with 2 tablespoons of freshly squeezed lemon juice. This clever combination effectively mimics the sharper acidity and complex tart-sweet balance that key limes provide, ensuring your cheesecake still delivers that signature tangy punch without the hassle. The lemon juice adds a crisp, bright note that complements the regular lime beautifully, creating a very similar flavor profile to genuine key lime juice.

Essential Equipment for Your Instant Pot Cheesecake
While I understand the reluctance to acquire yet another specialized kitchen gadget, making a flawless Instant Pot cheesecake truly necessitates a particular piece of equipment: a 7-inch springform pan. I initially attempted to find one at my local big box store without success, ultimately resorting to ordering one online. It might seem like an 8-inch pan, which many of us already own, would fit, but due to the way the springform clasp extends, it simply won’t clear the Instant Pot’s inner dimensions. Investing in a 7-inch pan is a small price to pay for cheesecake perfection. After experiencing the ease and quality of this Key Lime Cheesecake, I can confidently say this pan will become a frequently used item in my kitchen, proving its worth over and over again.
Of course, the star of this recipe is the pressure cooker itself. I rely on my trusty Instant Pot, which has revolutionized my cooking and baking. Most Instant Pot models come equipped with a trivet, an essential accessory for this recipe. The trivet elevates the cheesecake pan above the water at the bottom of the pot, ensuring it cooks perfectly via steam rather than sitting in liquid. This setup creates the ideal moist environment for cheesecake, preventing cracks and ensuring a creamy, delicate texture from edge to center. If your Instant Pot didn’t come with one, or you prefer a sturdier option, many aftermarket trivets are available. With these few key tools, you’re all set to create an unforgettable dessert!

Instant Pot Key Lime Cheesecake
Pin Recipe
Ingredients
- 1 cup graham cracker crumbs (from about 8 whole crackers)
- 3 tablespoons unsalted butter melted
- 1 tablespoon sugar
- 1 (8- oz) package cream cheese softened
- 1 (14 oz) can sweetened condensed milk
- 1/3 cup freshly squeezed key lime juice
- 1 large egg
- 1 tablespoon grated key lime zest
- 1/2 cup heavy whipping cream
- 2 tablespoons powdered sugar
- 1/2 teaspoon vanilla extract
Instructions
- Coat a 7-inch springform pan with nonstick cooking spray.
- In a small bowl, mix together the graham cracker crumbs, melted butter, and sugar. Press the crumbs into the springform pan and about 1 inch up the sides. Freeze the crust for 10 minutes.
- In another bowl, beat the cream cheese until it is smooth. Slowly beat in the sweetened condensed milk, then the lime juice, then the egg and lime zest. Do not overmix. Pour the batter into the frozen crust.
- Pour 1 cup of water into the bottom of the instant pot and place a trivet in the bottom. Carefully lower the pan into the Instant Pot. Lock the lid in place and turn the pressure release valve to the sealed position. Select high pressure for 25 minutes.
- When the time ends, let the pressure cooker release naturally for 10 minutes, then do a quick pressure release. When the valve drops, carefully remove the lid. Check the temperature of the cheesecake with an instant-read thermometer to ensure that the cheesecake has reached 150ºF. If needed, re-lock the lid and cook on high pressure for an additional 5 minutes, followed by another 10-minute natural release.
- Use a sling to transfer the cheesecake to a wire rack to cool. Use the edges of a paper towel to blot up any water that may have collected on the top or edges of the cheesecake.
- Once cool, cover the cheesecake with plastic wrap and transfer it to the refrigerator to chill for at least 4 hours, but preferably overnight.
- When ready to serve, make the vanilla whipped cream: in a bowl, beat the cream until it starts to thicken. Add the powdered sugar and the vanilla and continue to beat until stiff peaks form.
- Serve the cheesecake topped with the whipped cream.
