Fresh lemon zest and juice brighten every bite, while the blueberries add just the right amount of natural sweetness and color. They’re easy to make ahead, slice beautifully, and taste even better after chilling overnight. Whether you’re hosting a backyard barbecue or simply craving a refreshing low-carb treat, these cheesecake bars are guaranteed to impress.
Why This Recipe Works
These cheesecake bars capture the bright flavors of summer while keeping carbs low and texture incredibly creamy. The almond flour crust provides the perfect buttery base without becoming soggy, while fresh lemon juice and zest balance the richness of the cheesecake. Blueberries add pops of color and flavor without overwhelming the dessert, making every slice look as good as it tastes. Because they’re baked as bars instead of a traditional cheesecake, they’re simple to portion and perfect for gatherings or meal prep.
Pro Tips
- Bring the cream cheese to room temperature before mixing for the smoothest filling.
- Use fresh lemon juice instead of bottled for the brightest flavor.
- Toss the blueberries in a teaspoon of almond flour before adding them to help prevent sinking.
- Chill overnight for the cleanest slices and the best flavor.
- Wipe the knife clean between cuts for bakery-style presentation.
Variations
- Add fresh raspberries along with the blueberries for a mixed berry version.
- Top with lightly sweetened whipped cream before serving.
- Add a pinch of lavender to the filling for a subtle floral twist.
- Replace the blueberries with blackberries for a deeper berry flavor.

- Almond Crust
- 2 cups finely blanched almond flour
- ⅓ cup granulated monk fruit sweetener
- ½ teaspoon cinnamon (optional)
- ¼ teaspoon salt
- 6 tablespoons unsalted butter, melted
- 1 teaspoon vanilla extract
- Lemon Cheesecake Filling
- 24 ounces cream cheese, softened
- ¾ cup powdered monk fruit sweetener
- 2 large eggs
- 1 large egg yolk
- ¼ cup sour cream
- 2 tablespoons heavy cream
- Zest of 2 lemons
- 3 tablespoons fresh lemon juice
- 2 teaspoons vanilla extract
- Pinch of salt
- Blueberry Layer
- 1 cup fresh blueberries
- 1 teaspoon lemon zest
- Preheat the oven to 325°F. Line an 8x8-inch baking pan with parchment paper, leaving enough overhang to lift the bars out after chilling.
- In a medium bowl, combine the almond flour, monk fruit sweetener, cinnamon, and salt. Stir in the melted butter and vanilla until the mixture resembles damp sand.
- Press the crust evenly into the prepared pan. Bake for 10–12 minutes, or until lightly golden. Allow the crust to cool while preparing the filling.
- In a large mixing bowl, beat the softened cream cheese until completely smooth. Add the powdered sweetener and continue mixing until creamy.
- Mix in the eggs and egg yolk one at a time, scraping the bowl after each addition. Blend in the sour cream, heavy cream, lemon zest, lemon juice, vanilla, and salt until silky smooth.
- Pour the filling over the cooled crust and smooth the top with a spatula.
- Scatter the fresh blueberries evenly over the cheesecake. Gently press them just slightly into the batter and sprinkle with the additional lemon zest.
- Bake for 28–32 minutes, or until the edges are set and the center still has a slight jiggle.
- Turn off the oven, crack the door open, and let the cheesecake cool inside for 20 minutes.
- Cool completely at room temperature, then refrigerate for at least 4 hours, preferably overnight.
- Lift the cheesecake from the pan using the parchment paper and cut into 16 bars with a warm, clean knife.
