Recent Health Research:
A 2024 study published in Frontiers in Nutrition points to notable brain-boosting benefits from eating blueberries. The researchers observed that individuals who included blueberries in their regular diet showed better memory retention and stronger executive function. These effects are largely attributed to anthocyanins—the natural pigments responsible for blueberries’ rich color—which help combat oxidative stress in the brain while supporting healthy blood flow to key cognitive areas.
What makes these findings especially interesting for our Lemon Blueberry Cheesecake is that the benefits were seen with moderate intake—roughly the amount you’d enjoy in a single slice. Adding blueberries to your meals, even through a dessert like this, could play a role in supporting long-term cognitive health.

Tips for a Perfect No-Bake Cheesecake
Use Fresh Lemons: Always go for fresh lemons for both the juice and zest—the flavor is brighter, more vibrant, and far superior to bottled alternatives.
Take Your Time with the Lemon Curd: Cook it slowly over low, steady heat. Rushing can cause the eggs to scramble instead of forming a smooth, silky curd.
Allow Proper Setting Time: Let the cheesecake fully set before slicing. Cutting too early can lead to a soft, messy texture.
Slice Cleanly: For neat, bakery-style slices, wipe your knife clean after each cut.
Try Different Berries: Blueberries are a great choice, but raspberries or blackberries also pair beautifully with this recipe.
The Science Behind the Sweet: Continuous Glucose Monitoring Results
We didn’t just label this dessert as “keto-friendly” and call it a day—we validated it using continuous glucose monitoring (CGM) to reveal how your body may respond to it versus a traditional, sugar-heavy version.
In our initial test, I ate a slice of classic lemon blueberry cheesecake made with refined white sugar. My baseline blood glucose started at 84 mg/dL, then rapidly surged to 181 mg/dL shortly after eating. It took about 90 minutes for my levels to drop back to normal—a typical blood sugar spike and crash pattern that often leads to a quick burst of energy followed by fatigue and increased sugar cravings.
For the second test, I ate the same portion size of our keto lemon blueberry cheesecake—this time sweetened with allulose instead of regular sugar. The results were impressive. My blood glucose began at 91 mg/dL, stayed completely stable throughout the first hour, and even dipped slightly below baseline during the second hour.
The contrast was undeniable. The allulose-sweetened cheesecake caused virtually no spike in blood sugar. This kind of steady glucose response helps prevent energy crashes, reduces sudden hunger, and supports long-term metabolic health. It clearly shows how choosing the right sweetener can make a significant difference for anyone managing carbs or blood sugar levels.

Instructions
Prepare the Crust:
- Line the bottom of a 9-inch springform pan with parchment paper and lightly grease the sides.
- In a medium bowl, combine almond flour, melted butter, powdered allulose, cinnamon,and salt. Mix until crumbly and well combined.
- Press the mixture firmly into the bottom of the prepared pan, creating an even layer.
- Refrigerate the crust while preparing the fillings.
- For a browned crispier crust, bake at 375 degrees F for 8-10 minutes or until golden brown.
Prepare the Blueberry Swirl:
- In a small bowl, sprinkle 2 pkg. gelatin over 4 tbsp cold water and let it bloom for 5 minutes.
- In a small saucepan, combine strawberries, Allulose, and lemon juice.
- Cook over medium heat for about 10 minutes, mashing berries as they soften.
- Remove from heat and stir in the bloomed gelatin until dissolved.
- Allow to cool completely, then refrigerate until cold and slightly thickened. You want the mixture to set up enough to swirl into the cheesecake layer and spread on top without running off.
Prepare the Lemon Curd:
- In a heatproof bowl, whisk together egg yolks and powdered Allulose until lighter in color.
- Add lemon zest and juice, whisking to combine.
- Place the bowl over a pot of simmering water (double boiler method), making sure the bottom of the bowl doesn’t touch the water.
- Cook, stirring constantly with a spoon, until the mixture thickens and coats the back of a spoon (about 10-15 minutes).
- Remove from heat and stir in the cold, cubed butter until melted and fully incorporated.
- Strain the curd through a fine mesh sieve to remove zest and any cooked egg bits.
- Cover with plastic wrap directly on the surface (to prevent a skin from forming) and refrigerate until cool and thickened.
Prepare the Cheesecake Layer:
- In a small bowl, sprinkle 1 pkg gelatin over 2 tbsp cold water and let it bloom for 5minutes.
- Microwave the bloomed gelatin for 8-10 seconds until liquefied, then set aside to cool slightly.
- In a large bowl, beat the cream cheese until smooth and fluffy.
- Gradually add the powdered allulose, vanilla extract, salt, and lemon juice, beating until well combined.
- In a separate chilled bowl, whip the heavy cream until soft peaks form.
- Slowly pour the cooled gelatin into the whipped cream while beating, and continue until stiff peaks form.
- Remove 1 cup of the whipped cream and put it In a pastry bag fitted with a large star tip. Refrigerate until the cheesecake is ready to serve. Gently fold the rest of the whipped cream into the cream cheese mixture until fully incorporated.
Assemble the Cheesecake:
- Remove the chilled crust from the refrigerator.
- Spread half of the cheesecake mixture over the crust, smoothing with a spatula.
- Carefully spread the cooled lemon curd over the cheesecake layer, leaving a small border around the edge.
- Spoon the remaining cheesecake mixture over the lemon curd, gently spreading to the edges.
- Drop spoonfuls of the cooked blueberry mixture on top, then use a knife or skewer to create a swirl pattern. Use about half of the mixture for the swirl. Spread the rest of the cooked blueberries on top of the cake.
- Lightly spray some plastic wrap with cooking oil. This keeps the plastic wrap from sticking to the blueberry topping. Cover with the sprayed plastic wrap and refrigerate for at least 4-6 hours or overnight, until completely set.
To Serve:
- Pipe the reserved whipped cream into rosettes around the top of the cake. Garnish with a few lemon slices some lemon zest, fresh blueberries, and a few mint leaves. Run a knife around the edge of the springform pan before releasing.
- Slice with a clean, sharp knife dipped in hot water and wiped dry between cuts.

Notes
Storage:
Store the cheesecake covered in the refrigerator for up to 5 days. Do not freeze, as this will alter the texture of the no-bake layers.Notes:
- The gelatin is crucial for helping the cheesecake set properly.
- If allulose isn’t available, you can substitute it with erythritol or monk fruit sweetener (adjust quantities to taste as sweetness levels vary).
- For a smoother lemon curd, strain it through a fine mesh sieve to remove any bits of cooked egg.
