Don’t worry, the ingredients list is straightforward, and you probably have most of these kitchen essentials on hand!

- 3/4 cup granulated keto sweetener: Sweetens the cheesecake filling beautifully without the sugar crash.
- 3 large eggs (room temperature): Bind everything together and add richness to the filling.

How to Make Keto Blueberry Cheesecake Bars Recipe
Step 1: Prepare and Bake the Crust
Start by preheating your oven to 325°F and lining a 9×9-inch pan with parchment paper, leaving an overhang on the sides to help lift the bars out afterward. Stir together the almond flour, sweetener, and salt in a bowl, then pour in the melted butter and vanilla extract, mixing until evenly combined. Press this mixture firmly and evenly into the pan’s bottom. Baking it for 10 to 12 minutes gives the crust a lovely light golden color and helps it hold together perfectly under the creamy layers to come.
Step 2: Make the Blueberry Swirl
While the crust cools, create the vibrant blueberry swirl that makes this cheesecake recipe stand out. In a small saucepan over medium heat, combine the blueberries, sweetener, and lemon juice. Stir frequently as the berries burst and the mixture thickens into a jammy consistency, about 4 to 6 minutes. Stir in chia seeds if you want a thicker texture, cooking for an extra minute before removing from heat to cool. This swirl delivers that unmistakable fruity pop in every bite.
Step 3: Prepare the Cheesecake Filling
Beat the softened cream cheese with sweetener until smooth and fluffy using a mixer, scraping down the sides to ensure no lumps. Add eggs one at a time, mixing just until combined to preserve that silky texture. Stir in the sour cream, lemon juice, vanilla extract, lemon zest if you’re using it, and a pinch of salt. The result should be a luscious, velvety batter ready to layer over the crust.
Step 4: Assemble and Bake the Bars
Pour the cheesecake filling evenly over the cooled crust, smoothing the top with a spatula. Spoon dollops of the slightly cooled blueberry mixture across the surface, then gently swirl through with a knife or skewer to create beautiful marbled patterns—be careful not to overmix. Bake the bars for 35 to 45 minutes until the edges are set but the center jiggles just a little. Then, turn off the oven, crack the door, and let the bars cool inside for 15 minutes. This step helps prevent cracks and keeps your bars looking pristine.
Step 5: Cool and Chill
Remove the bars from the oven and allow them to cool completely at room temperature. Refrigerate for at least four hours or, even better, overnight. When ready, lift the bars out using the parchment overhang and slice into squares. For the cleanest cuts, a chilled knife wiped between slices works wonders.
How to Serve Keto Blueberry Cheesecake Bars Recipe
Garnishes
Add a fresh twist by topping your cheesecake bars with a few whole blueberries or a sprinkle of lemon zest to enhance the fruity and citrus notes. A dollop of unsweetened whipped cream drizzled with a little sugar-free blueberry sauce also makes for an irresistible presentation that will wow your guests.
Side Dishes
Pair these bars with a light cup of unsweetened herbal tea or a frothy keto-friendly coffee for a perfect afternoon treat. A handful of toasted nuts or a crisp green salad with a lemon vinaigrette can balance out the richness if you’re serving this as part of a larger dessert spread.
Creative Ways to Present
For special occasions, serve your Keto Blueberry Cheesecake Bars Recipe on a pretty platter with edible flowers or fresh mint sprigs. You can also layer smaller squares in clear dessert cups with whipped cream and blueberry sauce for an elegant, single-serving parfait look. The possibilities to impress are endless!
Make Ahead and Storage
Storing Leftovers
Keep leftover cheesecake bars covered tightly in the refrigerator for up to five days. The flavors actually develop more deeply after a day or two, making this dessert even more irresistible with time. Be sure to store the bars in a single layer or with parchment paper between layers to prevent sticking.
Freezing
These bars freeze beautifully! Place them in an airtight freezer container or wrap tightly with plastic wrap and foil, then freeze for up to three months. Thaw overnight in the refrigerator before serving to maintain their creamy texture and lovely fruity swirl.
Reheating
Since these are cheesecake bars, they are best enjoyed chilled or at room temperature. However, if you prefer them slightly warmed, let them sit on the counter for 15 to 20 minutes, or microwave a piece for 10 to 15 seconds—just avoid overheating to preserve texture.
FAQs
Can I use frozen blueberries for the blueberry swirl?
Absolutely! Just keep in mind that frozen berries release more liquid, so cook the blueberry mixture a couple of minutes longer to reduce extra moisture. This ensures a thick, jammy swirl without watering down the filling.
What keto sweetener is best for this recipe?
Both erythritol and allulose work well. Allulose tends to keep the cheesecake softer and less gritty, while erythritol can sometimes leave a slight cooling aftertaste. Choose what you prefer and what you have on hand.
Can I add other berries or fruits instead of blueberries?
Yes, feel free to experiment with raspberries, blackberries, or even a mix of berries for a different flavor profile. Just adjust cooking time if needed to ensure the swirl is nicely thickened.
Why does the cheesecake sometimes crack on top?
Cracking usually happens when the cheesecake cools too quickly or gets overbaked. Following the step to cool the bars gradually in the oven with the door cracked open helps prevent cracks and keeps your cheesecake smooth and pretty.
Can I make this recipe dairy-free?
This recipe relies heavily on cream cheese and sour cream for texture and flavor, so making it fully dairy-free would be challenging. However, experimenting with dairy-free cream cheese alternatives might work, but texture and taste could vary.
Final Thoughts
I cannot recommend enough giving this Keto Blueberry Cheesecake Bars Recipe a try the next time you’re craving a luscious dessert that won’t wreck your keto goals. It’s joyful to make, gorgeous to serve, and absolutely delightful to eat. Once you taste that creamy filling, nutty crust, and fruity swirl, you’ll wonder why you didn’t make it sooner. Trust me, these bars are going to become your new go-to when dessert calls.

Press this mixture firmly into the bottom of the prepared pan in an even layer. Bake for 10 to 12 minutes until the edges are lightly golden. Remove and let cool for 10 minutes.
- Prepare the blueberry swirl: In a small saucepan over medium heat, combine blueberries, sweetener, and lemon juice. Cook for 4 to 6 minutes, stirring frequently, until the berries burst and the mixture thickens to a jam-like consistency. Stir in chia seeds if using, cook for 1 more minute, then remove from heat and let cool slightly.
- Make the cheesecake filling: Using a mixer, beat softened cream cheese and sweetener together until smooth and fluffy, scraping down bowl sides as needed.
