What Makes This Dessert Sugar-Free?
This recipe uses granulated and powdered sugar-free sweeteners instead of regular sugar. Allulose, monk fruit, erythritol blends, or other baking-friendly sugar substitutes can work well.

The result is a dessert that tastes like a classic lemon blueberry cheesecake but fits better into sugar-free and lower-carb eating plans.

How to Make Sugar-Free No-Bake Lemon Blueberry Dessert
This dessert is assembled in layers and then chilled until set.
Make the Crust
Mix graham cracker crumbs, melted butter, sugar-free sweetener, and salt until evenly moistened.
Press the mixture firmly into a 9×13-inch dish. Use the bottom of a measuring cup or glass to compact it evenly.
Refrigerate while preparing the filling. This helps the crust set and stay firm.
Make the Lemon Cream Layer
Beat the cream cheese until smooth and creamy.
Add powdered sugar-free sweetener, lemon pudding mix, cold milk, lemon juice, and lemon zest.
Mix until thick and creamy. Do not overmix, or the filling may become too soft.
Fold in the whipped topping until light and fluffy. Be gentle to keep the filling airy.
Spread evenly over the chilled crust.
Make the Blueberry Layer
Add blueberries, water, sugar-free sweetener, lemon juice, and cornstarch to a saucepan.
Cook over medium heat, stirring often, until the mixture thickens and the blueberries soften. This should take about 5 to 7 minutes.
Remove from the heat and cool completely. The mixture will thicken more as it cools.
Assemble
Spread the cooled blueberry mixture evenly over the lemon cream layer.
Add the whipped topping and spread gently.
Garnish with fresh blueberries and lemon zest for a beautiful, vibrant finish.
Chill and Serve
Cover and refrigerate for at least 4 hours, preferably overnight.
Slice and serve chilled for the best texture and flavor.
Texture and Flavor
This lemon blueberry dessert has a buttery, crisp crust, a smooth and creamy lemon filling, and a juicy, sweet blueberry topping. The crust is compact and holds the layers together, while the lemon filling is light and tangy.
The blueberry layer adds bursts of sweet, juicy fruit that complement the bright citrus flavor. Fresh lemon zest enhances the aroma and taste, making every bite feel fresh and summery.
Served chilled, it feels refreshing and indulgent at the same time.
Tips for the Best Results
A few small details can help your lemon blueberry dessert turn out perfectly.
Cool the Blueberry Layer
Let the blueberry mixture cool completely before spreading it over the lemon filling. A warm topping can soften the cream layer.
Use Fresh Lemon Zest
Fresh lemon zest gives the brightest citrus flavor. Bottled lemon zest or extract will not taste as vibrant.
Chill Overnight
Chill for at least 4 hours, or preferably overnight, for cleaner slices and a firmer texture.
Press the Crust Firmly
Press the crust firmly so it stays compact beneath the creamy layers. A loose crust can crumble when slicing.
Pat Blueberries Dry
Pat fresh blueberries dry before using them as garnish. This prevents excess moisture from making the topping soggy.
Easy Variations
This recipe is easy to customize with different flavors and toppings.
Add Raspberries
Replace half the blueberries with fresh raspberries for a lemon-raspberry version.
Add Strawberries
Use sliced strawberries instead of blueberries for a lemon-strawberry twist.
Add Poppy Seeds
Add 1 to 2 tablespoons of poppy seeds to the lemon filling for a lemon-poppy seed dessert.
Make It Dairy-Free
Use dairy-free cream cheese, almond milk, and dairy-free whipped topping for a dairy-free version.
Add Coconut
Sprinkle unsweetened shredded coconut on top before serving for a tropical touch.
Serving Ideas
This lemon blueberry dessert is best served chilled. A garnish of fresh blueberries and lemon zest makes it look and taste extra special.
It is perfect for summer picnics, barbecues, holiday gatherings, or any time you want a bright, refreshing dessert. Because it is made in a 9×13 pan, it is easy to cut into squares for serving a crowd.
Storage Tips
Store leftovers covered in the refrigerator for up to 4 days.
Keep the dessert covered with plastic wrap or transfer individual squares to an airtight container.
For the best texture, serve it chilled. The flavor becomes more vibrant as it sits.

Common Mistakes to Avoid
A few simple mistakes can affect the texture of this lemon blueberry dessert.
Not Cooling the Blueberry Layer
If the blueberry topping is still warm, it can soften the cream layer. Let it cool completely before assembling.
Not Chilling Long Enough
The dessert needs at least 4 hours to set. Chilling overnight gives the cleanest slices.
Overmixing the Filling
Fold the whipped topping gently to keep the filling light and airy. Overmixing can deflate it.
Loose Crust
Press the crust firmly so it stays compact. A loose crust can crumble when slicing.
Using Bottled Lemon Zest
Fresh lemon zest tastes brighter than bottled. Use fresh zest for the best flavor.
