That's exactly why we perfected this recipe through a number of kitchen experiments.

Ingredients
Let's dive into why each ingredient plays a crucial role in creating this perfect keto dessert:
Almond Flour: This is the star of our keto cheesecake crust. Unlike coconut flour, almond flour creates a texture that's remarkably similar to traditional graham cracker crumbs. We recommend using finely ground almond flour for the smoothest results. The key is finding quality almond flour that won't make your crust taste too nutty or fall apart. Store-bought almond flour works perfectly – just make sure it's fresh and hasn't developed any bitter notes.
Butter: Essential for binding the crust and adding that rich, buttery flavor. Make sure your butter is at room temperature for easier mixing in the food processor. Cold butter won't incorporate properly, while melted butter can make the crust too soggy.
Egg Yolk: This single egg yolk is crucial for binding the crust ingredients together and creating that perfect shortbread-like texture. The yolk adds richness and helps prevent the crust from crumbling when you slice the cheesecake. Don't substitute with whole egg – the extra moisture from the egg white can make the crust soggy.
Salt (pinch): Never underestimate the power of a bit of salt in desserts! This small amount enhances all the other flavors and balances the sweetness. It's essential in keto baking, where we're using alternative sweeteners that sometimes need that extra flavor boost.
Allulose: This is our secret weapon for the creamy filling. Allulose behaves almost identically to regular sugar but without the carbs. It dissolves beautifully and doesn't leave any cooling aftertaste like some other keto sweeteners. If you can't find allulose, you can substitute it with different alternative sweeteners, but the texture might vary slightly.
Fresh Lemons: We use both fresh lemon juice and lemon zest for maximum lemon flavor. Fresh lemons are non-negotiable here – bottled lemon juice just won't give you that bright, vibrant taste that makes this dessert shine. The zest adds aromatic oils that intensify the lemon dessert experience.
Heavy Cream: This creates the ultra-creamy texture that makes the cheesecake so indulgent. Heavy cream whips beautifully and adds richness without excess carbs. Make sure it's cold when you're preparing the topping for better whipping results.
Gelatin: This helps set the filling without making it rubbery. Sheet gelatin dissolves more smoothly than powder, but you can substitute with powdered gelatin if needed. The gelatin ensures your cheesecake holds its shape when sliced.
Cream Cheese: For the topping, cream cheese adds tang and richness. Let it come to room temperature before mixing for the smoothest results.
Monk Fruit Sweetener: Perfect for the topping because it doesn't interfere with the cream's ability to whip. Monk fruit blends seamlessly and doesn't add any bitter aftertaste.

Step-by-Step Instructions
Preparing the Perfect Crust
The crust is the foundation of any great cheesecake, and this one won't disappoint. For the best results, you'll need a food processor with sharp blades.
- Combine dry ingredients: Add almond flour, a pinch of salt, and butter to your food processor container. Mix until the mixture resembles shortcrust pastry – it should hold together when pressed but not be overly wet.
- Add the binding: Incorporate the egg yolk and mix until everything comes together into a cohesive dough.
- Chill the dough: Remove the pastry from the container, form it into a ball with your hands, and wrap it in plastic wrap. Refrigerate for 30 minutes—this step is crucial for easy handling.
- Press and shape: After chilling, press the dough into your 8 in (21 cm) diameter springform pan, working it up the sides and ensuring even coverage across the bottom of the pan. Use a fork to perforate the base – this prevents the crust from puffing up during baking.
- Second chill: Refrigerate for another 15 minutes while you preheat your oven to 355°F (180°C).
- Blind bake: Place parchment paper over the crust and add rice or ceramic baking beans to prevent rising. Bake for 15 minutes, then carefully remove the parchment paper and continue baking for 5-7 minutes until golden brown.
- Cool completely: Set the crust aside to cool while you prepare the filling.
Creating the Luscious Filling
This is where the magic happens—creating the perfectly smooth, lemony filling that sets this recipe apart from many other keto cheesecakes.
- Combine sweetener and zest: In a small pot, thoroughly mix the allulose with freshly grated lemon zest. This step helps release the essential oils from the zest.
- Add wet ingredients: Mix in the eggs and fresh lemon juice, stirring until well combined.
- Incorporate cream: Add the heavy cream and stir well. The mixture should be smooth and uniform.
- Gentle heating: Start heating on low heat, stirring constantly. Once the mixture reaches 105°F (40°C), strain it through a fine sieve to remove the zest pieces.
- Continue heating: Keep heating until the mixture reaches 185°F (85°C), then remove from heat and immediately add the gelatin sheets.
- Final mixing: Stir continuously for 2-3 minutes to ensure the gelatin dissolves completely.
- Assemble: Pour the filling over the cooled crust and refrigerate for approximately 10 minutes until the top starts to set slightly.
- Trim and release: Remove from the fridge, carefully trim any excess crust edges, and release the sides of the springform pan. Refrigerate the cake while you make the topping cream.
The Finishing Touch: Topping Cream
- Whip the topping: In a large bowl, combine cream cheese (at room temperature), monk fruit sweetener, and heavy cream. Use an electric mixer on medium speed until the mixture is smooth and holds soft peaks.
- Pipe and decorate: Transfer the cream to a pastry bag and pipe decorative rosettes across the top of your cheesecake. For the best visual impact, aim for rosettes about 0.5cm wide.
- Final chill: Refrigerate until ready to serve. For faster setting, place in the freezer for 10-15 minutes first, then transfer to the refrigerator.
Pro Tips for Success
- Room temperature matters: Ensure your cream cheese and butter are at room temperature for smooth mixing
- Don't skip the chilling: Each chilling step is crucial for the proper texture and structure
- Quality ingredients: Use fresh lemons and high-quality almond flour for the best results
- Strain the filling: This removes any lumps and ensures a silky smooth texture

Frequently Asked Questions
While a food processor gives the best results for the crust, you can use a large mixing bowl and cut the butter into the almond flour with a pastry cutter or even your hands. A stand mixer with a paddle attachment also works well.
You can use a regular 8- or 9-inch round cake pan, but you'll need to line it with parchment paper for easy removal. The springform pan makes serving much easier, though.
Yes, but the texture may vary slightly. Erythritol works well but might crystallize when cold. Stevia is much sweeter, so you'd need less. Check our sugar-free baking conversion guide for more information.
Stored properly in the refrigerator, it will keep for up to 5 days. You can also freeze individual slices for up to 3 months.
Sure! Divide the recipe among muffin tins lined with paper cups. Reduce the baking time for the crusts to about 8-10 minutes.
This recipe is very versatile! Try adding lime zest for a different citrus twist, or fold in fresh berries for extra flavor and color. However, make sure the berries do not release juice, or it would impact the cake's texture.
This usually happens when the almond flour is too coarse or the mixture is too dry. Make sure to use finely ground almond flour and don't skip the egg yolk – it's crucial for binding. The crust should have a perfect texture if you stick to the recipe precisely.
Use a sharp knife dipped in hot water and wiped clean between each cut. This prevents the creamy filling from sticking to the blade.
Serving Suggestions and Variations
This delicious lemon cheesecake is perfect on its own, but here are some ways to make it even more special:
- Fresh berries: Top with fresh blueberries or strawberries for added color and flavor
- Lemon slices: Garnish with thin lemon slices for an elegant presentation
- Whipped cream: Add a dollop of sugar-free whipped cream for extra indulgence
- Berry compote: Make a quick sugar-free berry sauce to drizzle over each slice

- 1 egg yolk
- a pinch of salt
The filling cream:
- 7 oz (200 g) allulose
- 4 small/medium-sized lemons
- 4 eggs
- 10 oz (300 mL) heavy cream
- 6 sheets of gelatin
The topping cream:
- ½ cup (125 g) cream cheese
- 3.3 oz (100 g) heavy cream
- 2 oz (55 g) monk fruit sweetener
Instructions
Prepare the crust
- For the crust, you'll need a food processor with sharp blades.Add almond flour, a pinch of salt, allulose, and butter to the food processor container. Mix all the ingredients until thoroughly combined and the mixture resembles shortcrust pastry.
- Add the yolk, and mix to incorporate the yolk into the pastry.
- Remove the pastry from the container and form a ball using hands. Wrap into a food plastic wrap and refrigerate for 30 minutes.
- After 30 minutes, remove the pastry from the refrigerator and layer it in a baking pan, while pressing with your fingers against the bottom and sides of the baking pan. We used a 21cm diameter baking pan. Perforate the bottom of the crust with a fork so the crust remains flat while baking and doesn't inflate.
- Refrigerate for another 15 minutes for the pastry to cool down. Meanwhile, preheat the oven to 180°C (355°F).
- Lay parchment paper on the pastry and pour rice or ceramic peas on top. It will prevent the pastry from rising during the cooking.
- Bake for 15 minutes.
- Take the crust out of the oven, remove the parchment paper carefully, and continue baking for another 5-7 minutes until golden brown.
- Take the crust out of the oven and set aside to cool down. Meanwhile, you can start preparing the filling cream.
Prepare the filling cream
- Add allulose, and lemon zest, and mix thoroughly in a small pot.
- Mix eggs and freshly juiced lemon juice into the allulose mixture.
- Add heavy cream and stir well. Start heating on low heat.
- Once the temperature of the mixture reaches 40°C (105°F), sieve it (to remove the zest), and continue heating until it reaches 85°C (185°F). Then, add gelatin.
- Turn off the heat and continue stirring for another 2-3 minutes to allow the gelatin to melt completely.
- Pour the mixture over the cake crust. Refrigerate for approx. 10 minutes (the top of the cake will have thickened slightly).
- Remove the cake from the refrigerator. Cut off the crust's sides that extend outside the filling cream level. As a result, you should have a leveled-out top of the cake.
- Take off the sides of the baking pan. Return the cake to the refrigerator while you prepare the topping cream.
Prepare the topping cream and decorate the cake:
- Mix cream cheese with monk fruit sweetener and heavy cream. Whisk until the mixture is thoroughly combined and uniform in texture.
- Transfer the cream to a pastry bag. Pipe the cream onto the cake. We aimed at approx. 0.5cm wide rosettes.
- Serve refrigerated. If you're short of time, start by placing the cake into the freezer for about 10-15 minutes (at -18°C temperature), then transfer the cake to the fridge until you need to serve it.
