These Low Carb Lemon Blueberry Cheesecake Bars are creamy, tangy, and bursting with fresh blueberry flavor. A buttery almond-flour crust supports a silky lemon cheesecake layer swirled with juicy blueberries, creating the perfect balance of rich, bright, and fruity flavors. They are delicious chilled straight from the refrigerator and make a beautiful dessert for spring, summer gatherings, afternoon coffee, or whenever you want something special without traditional flour and sugar.
🍋 Can These Low Carb Lemon Blueberry Cheesecake Bars Support Weight Loss Goals?
These cheesecake bars can fit into a balanced weight-conscious eating pattern when enjoyed in a sensible portion. Cream cheese and eggs provide protein and fat, while almond flour contributes fiber and satisfying fats. Using a low-carb sweetener instead of regular sugar helps reduce added carbohydrates compared with conventional cheesecake bars.
💪 Do These Lemon Blueberry Cheesecake Bars Fit a High-Protein Lifestyle?
They can fit into a high-protein lifestyle, although they are still primarily a dessert rather than a high-protein meal. Cream cheese, eggs, and almond flour contribute protein, while blueberries add fiber and natural fruit flavor. The controlled amount of berries and low-carb sweetener helps keep the net carbs lower than traditional blueberry cheesecake bars. For extra protein, enjoy a smaller serving with plain Greek-style yogurt.

📝 Ingredients
For the Almond Flour Crust
- 1½ cups almond flour
- 3 tablespoons low-carb granulated sweetener
- ¼ teaspoon salt
- 5 tablespoons unsalted butter, melted
- ½ teaspoon vanilla extract
For the Blueberry Layer
- 1 cup fresh or frozen blueberries
- 2 tablespoons low-carb granulated sweetener
- 1 teaspoon fresh lemon juice
- 1 teaspoon lemon zest
- 1 teaspoon cornstarch
- 1 tablespoon water
For the Lemon Cheesecake Filling
- 16 ounces full-fat cream cheese, softened
- ½ cup low-carb granulated sweetener
- 2 large eggs
- ¼ cup sour cream
- 2 tablespoons fresh lemon juice
- 1 tablespoon finely grated lemon zest
- 1 teaspoon vanilla extract
👩🍳 Directions
- Preheat the oven: Heat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving some overhang on the sides.
- Prepare the crust: Mix almond flour, low-carb sweetener, salt, melted butter, and vanilla until the mixture resembles moist crumbs.
- Press the crust: Firmly press the mixture into the bottom of the prepared pan, creating an even layer.
- Bake the crust: Bake for 10–12 minutes, until lightly golden around the edges. Remove and allow it to cool slightly.
- Make the blueberry mixture: Add blueberries, sweetener, lemon juice, and lemon zest to a small saucepan over medium-low heat.
- Cook the berries: Simmer for 4–6 minutes, stirring gently, until the berries soften and release their juices.
- Thicken: Mix the cornstarch and water in a small bowl. Stir it into the blueberries and cook for another 1–2 minutes, until thick and jammy. Remove from the heat and let it cool.
- Prepare the cheesecake filling: Beat the softened cream cheese and sweetener on low to medium speed until smooth and creamy.
- Add the eggs: Add the eggs one at a time, mixing only until each one is incorporated. Avoid whipping excessive air into the mixture.
- Finish the filling: Add sour cream, lemon juice, lemon zest, and vanilla. Mix gently until completely smooth.
- Layer the cheesecake: Pour the cheesecake mixture over the cooled crust and smooth the surface with a spatula.
- Add blueberries: Spoon small amounts of the cooled blueberry mixture over the cheesecake layer.
- Create the swirl: Use a toothpick or skewer to gently swirl the blueberry mixture through the cheesecake. Do not over-swirl, or the colors may blend together.
- Bake: Reduce the oven temperature to 325°F (165°C) and bake for 25–30 minutes, until the edges are set and the center still has a slight gentle jiggle.
- Cool gradually: Turn off the oven and leave the cheesecake inside with the door slightly open for about 15 minutes. Remove and allow it to cool completely at room temperature.
- Chill: Refrigerate for at least 4 hours, preferably overnight, until completely firm.
- Slice: Lift the cheesecake from the pan using the parchment overhang. Cut into 12 bars with a sharp knife, wiping the knife between cuts.
