This recipe delivers a perfectly set, luxuriously creamy, and refreshingly light cheesecake without turning on the oven. The secret is in properly blooming the gelatin, whipping the cream to the right consistency, and allowing enough time for the cake to set completely.
1. Ingredients You’ll Need (for the Base)
For the Crust:
- 200g (7 oz) digestive biscuits or butter cookies (e.g., Petit Beurre)
- 100g (3.5 oz / 7 tbsp) unsalted butter, melted
- 1 tbsp granulated sugar (optional)
For the Filling:
- 500g (1.1 lbs) full-fat cream cheese (e.g., Philadelphia), room temperature
- 200g (1 cup) granulated sugar, fine
- 250ml (1 cup) heavy cream (30-36% fat), very cold
- 1 tsp vanilla extract
- 200ml (ยพ cup) plain, full-fat Greek yogurt or sour cream
- 15g (4 tsp) powdered gelatin (or 6 sheets of leaf gelatin)
- 80ml (โ cup) cold water (for blooming gelatin)
- Zest of 1 lemon

- Calories: Approximately 450-550 kcal per slice (1/10th of the cake).
- Note: This is a rich dessert. The calorie count is high due to the cream cheese, heavy cream, and sugar. Values change significantly with different toppings.
3. Step-by-Step Instructions (Detailed with Tips)
Step 1: Prepare the Crust
- Pro Tip: Using a food processor ensures fine, even crumbs that will form a solid base. If you don’t have one, place the biscuits in a zip-top bag and crush them with a rolling pin.
- Line the bottom of a 23cm (9-inch) springform pan with parchment paper.
- Process the biscuits into fine crumbs. Mix with the melted butter (and optional sugar) until it resembles wet sand.
- Press the mixture firmly and evenly into the bottom of the prepared pan. Use the bottom of a glass to compact it.
- Chill in the refrigerator while you prepare the filling.
Step 2: Bloom the Gelatin
- Pro Tip: “Blooming” gelatin hydrates the granules so they dissolve smoothly into the filling without forming lumps.
- For Powdered Gelatin: Sprinkle the gelatin evenly over the surface of the 80ml of cold water in a small bowl. Do not stir. Let it sit for 5-10 minutes until it becomes a solid, spongy gel.
- For Leaf Gelatin: Place the sheets in a bowl of cold water for 5-7 minutes until soft and floppy. Squeeze out excess water before using.
Step 3: Prepare the Filling Base
- In a large bowl, beat the room-temperature cream cheese with an electric mixer until completely smooth and lump-free. This is crucial for a silky texture.
- Add the sugar and beat until well combined. Then, mix in the Greek yogurt (or sour cream), vanilla extract, and lemon zest.
Step 4: Melt the Gelatin
- Pro Tip: Do not let the gelatin boil, as this can damage its setting properties.
- Take the bloomed powdered gelatin (or the softened leaf gelatin) and place it in a heatproof bowl set over a pot of simmering water (double boiler). Heat gently, stirring, until it becomes a clear liquid. Alternatively, microwave for 10-15 seconds until liquid.
- Take a few spoonfuls of the cream cheese mixture and vigorously whisk it into the liquefied gelatin. This tempers it and prevents it from setting into strings when added to the main bowl.
Step 5: Whip and Combine
- In a separate, chilled bowl, whip the very cold heavy cream until it forms medium peaks (soft, but holding its shape).
- Pour the tempered gelatin mixture into the main cream cheese batter and whisk quickly until fully incorporated.
- Gently fold the whipped cream into the cream cheese mixture in two additions using a spatula. Use a cutting and folding motion to keep the mixture light and airy. Do not overmix.
Step 6: Assemble and Set
- Pour the filling over the prepared crust. Smooth the top with a spatula.
- Tap the pan gently on the counter to release any air bubbles.
- Cover the pan with plastic wrap and refrigerate for a minimum of 6 hours, but ideally overnight for it to set perfectly.
Variant 1: With Blueberry Topping
This adds a sweet, tangy, and vibrant layer that cuts through the richness of the cheesecake.
Ingredients for Topping:
- 250g (2 cups) fresh or frozen blueberries
- 3 tbsp granulated sugar
- 1 tbsp lemon juice
- 1 tsp cornstarch mixed with 2 tbsp cold water (slurry)
Instructions:
- In a small saucepan, combine the blueberries, sugar, and lemon juice.
- Cook over medium heat for 5-7 minutes until the berries break down and release their juices.
- Stir in the cornstarch slurry. Bring to a simmer, stirring constantly, until the mixture thickens noticeably (about 1-2 minutes).
- Remove from heat and let it cool completely to room temperature.
- Once the cheesecake is fully set, spread the cooled blueberry topping evenly over the surface.
- Return to the fridge for at least 30 minutes for the topping to set.
Variant 2: Without Topping
The pure, unadulterated version. Perfect for showcasing the creamy, lemony flavor of the cheese itself.
Serving Suggestion:
Serve plain, or garnish simply with a light dusting of powdered sugar, fresh berries, or a mint leaf just before serving.
Variant 3: Vegetarian Version
This version substitutes the standard gelatin, which is animal-based, with agar-agar, a plant-based gelling agent derived from seaweed.
Substitutions & Method Adjustments:
- Replace the 15g powdered gelatin with 4 tsp (8g) powdered agar-agar.
- Crucial Method Change: Agar-agar must be boiled to activate. Do not just melt it.
- Bloom the agar-agar in the 80ml of cold water as before.
- Then, bring the mixture to a full boil and simmer for 1-2 minutes, stirring constantly, until completely dissolved.
- Immediately proceed with tempering it into the cream cheese mixture (as in Step 5 of the base recipe).
- Note: Agar-agar sets firmer and faster than gelatin. The texture will be slightly less creamy and more like a soft jelly. Work quickly after adding it, as it begins to set at around 40ยฐC (104ยฐF).
