These Lemon Blueberry Cheesecake Bars combine a buttery shortbread crust, creamy lemon cheesecake filling, juicy blueberries, and a golden crumble topping in every bite.
The fresh lemon keeps the cheesecake bright and balanced, while the blueberries become soft and jammy as the bars bake. A generous buttery crumble on top gives them just enough crunch to contrast with the smooth cheesecake layer.
They’re beautiful enough for spring and summer gatherings but simple enough to make whenever you’re craving an easy blueberry dessert.
Why You’ll Love This Recipe

Ingredient Notes
Cream cheese: Use full-fat block-style cream cheese. Avoid whipped cream cheese or cream cheese spread because they contain more moisture.
Blueberries: Fresh blueberries give the best texture, but frozen blueberries can also work. If using frozen berries, don’t thaw them first.
Lemon: Use both fresh lemon zest and juice. The zest provides most of the fragrant lemon flavor.
Butter: Unsalted butter gives you better control over the salt and creates a rich shortbread-style base.
Flour: Regular all-purpose flour works for both the crust and crumble.
Sour cream: Adds creaminess and a slight tang to the cheesecake filling.

Ingredients
For the Buttery Crust & Crumble
- 2 cups (250 g) all-purpose flour
- ¾ cup (150 g) granulated sugar
- ½ teaspoon baking powder
- ¼ teaspoon salt
- ¾ cup (170 g) unsalted butter, melted and slightly cooled
- 1 teaspoon pure vanilla extract
- 1 teaspoon finely grated lemon zest
For the Lemon Cheesecake Filling
- 16 oz (450 g) full-fat block cream cheese, softened
- ½ cup (100 g) granulated sugar
- 2 large eggs, room temperature
- ⅓ cup (80 g) sour cream
- 2 tablespoons fresh lemon juice
- 1 tablespoon finely grated lemon zest
- 1 teaspoon pure vanilla extract
- 1 tablespoon all-purpose flour
- Pinch of salt
For the Blueberry Layer
- 2 cups (300 g) fresh blueberries
- 1 tablespoon granulated sugar
- 1 tablespoon fresh lemon juice
- 2 teaspoons cornstarch
Instructions
1. Prepare the pan
Preheat the oven to 350°F (175°C).
Line an 8 × 8-inch baking pan with parchment paper, leaving enough overhang on two sides to lift the chilled bars from the pan later.
Lightly grease any exposed sides.
2. Make the crust and crumble
In a medium bowl, combine the flour, sugar, baking powder, and salt.
Add the melted butter, vanilla, and lemon zest.
Mix with a fork until the mixture forms moist, buttery crumbs.
It should hold together when pressed but still contain plenty of irregular crumbles.
Reserve approximately 1 cup of the mixture for the topping.
3. Bake the crust
Press the remaining mixture firmly and evenly into the bottom of the prepared pan.
Bake for 12–14 minutes, until the edges are just beginning to turn golden.
Remove from the oven and let cool slightly while preparing the filling.
Keep the oven at 350°F.
4. Prepare the blueberries
Add the blueberries to a bowl and gently toss them with the sugar, lemon juice, and cornstarch.
Set aside.
The cornstarch will help absorb some of the berry juices as the bars bake.
5. Make the lemon cheesecake filling
Place the softened cream cheese and sugar in a large bowl.
Beat on medium-low speed until completely smooth and creamy.
Don’t whip excessively; too much incorporated air can cause cheesecake to rise and crack.
Add the eggs one at a time, mixing on low speed after each addition.
Add the sour cream, lemon juice, lemon zest, vanilla, flour, and salt.
Mix just until smooth.
6. Assemble the bars
Pour the cheesecake filling over the partially baked crust and spread it evenly.
Scatter the blueberry mixture over the cheesecake.
Some berries will naturally sink slightly into the filling.
Take the reserved crumble mixture and break it into different-sized pieces with your fingers.
Scatter it loosely over the blueberries. Don’t completely cover the fruit — you want some blueberries visible between the golden crumble pieces.
7. Bake
Bake for approximately 38–45 minutes.
The edges should look set while the very center should still have a slight wobble when you gently move the pan.
The crumble should be lightly golden.
Avoid overbaking. The cheesecake continues setting as it cools.
8. Cool gradually
Place the pan on a wire rack and allow the bars to cool completely at room temperature.
Once cooled, cover and refrigerate for at least 4 hours, preferably overnight.
This chilling time is essential for clean slices and the best cheesecake texture.
9. Slice
Use the parchment overhang to carefully lift the cheesecake from the pan.
For clean cuts, use a large sharp knife and wipe the blade clean between slices.
Cut into 16 squares.
Serve chilled or allow them to sit at room temperature for about 10 minutes before serving for a slightly softer cheesecake texture.
Tips for Perfect Cheesecake Bars
Use room-temperature cream cheese. Cold cream cheese tends to leave small lumps in the filling.
Don’t overmix the eggs. Once the eggs are added, use low speed and stop as soon as everything is incorporated.
Don’t crush the blueberries. Keeping some berries whole creates those beautiful purple pockets you see in the finished bars.
Make an irregular crumble. Small crumbs mixed with larger buttery chunks give the topping a more homemade appearance and better texture.
Chill before cutting. Warm cheesecake bars will be messy. Four hours is the minimum; overnight is even better.
Use parchment paper. It makes removing the entire cheesecake from the pan much easier.
Can I Use Frozen Blueberries?
Yes. Add them directly from frozen rather than thawing them.
Frozen blueberries may release slightly more liquid and create more purple streaks in the cheesecake. You may need a few additional minutes of baking time.
Variations
Raspberry Lemon Cheesecake Bars
Replace the blueberries with fresh raspberries for a more tart berry flavor.
Mixed Berry Cheesecake Bars
Use a combination of blueberries, raspberries, and finely chopped strawberries.
Extra Lemon Cheesecake Bars
Add another teaspoon of lemon zest to the filling. I wouldn’t add substantially more lemon juice because excess liquid can affect the cheesecake texture.
Blueberry Cheesecake Bars Without Crumble
Use all the crust mixture for the base and leave the top uncovered for a simpler traditional blueberry cheesecake bar.
Storage
Store the bars in an airtight container in the refrigerator for up to 5 days.
Because they contain cheesecake, don’t leave them sitting at room temperature for extended periods.
Can You Freeze Them?
Yes. Once completely chilled, arrange the bars in a freezer-safe container with parchment between the layers.
Freeze for up to 2 months.
Thaw overnight in the refrigerator before serving.
Frequently Asked Questions
Why did my cheesecake bars crack?
Overmixing the eggs or overbaking can cause cracks. Fortunately, the blueberries and crumble topping make minor cracks virtually invisible.
How do I know when cheesecake bars are finished baking?
The outside should be set, but the center should retain a slight jiggle. It will firm up considerably as it cools and chills.
Why are my blueberry cheesecake bars watery?
The berries may have released excessive moisture. Tossing them with a small amount of cornstarch helps thicken their juices during baking.
Can I make these the day before?
Yes — this is actually the best way to make them. Bake the bars the day before, refrigerate overnight, and slice them the following day.
Do Lemon Blueberry Cheesecake Bars need to be refrigerated?
Yes. Because they’re made with cream cheese, eggs, and sour cream, keep the finished bars refrigerated.
What to Serve with Lemon Blueberry Cheesecake Bars
They’re excellent on their own, but for a special dessert you can add fresh blueberries, a little lemon zest, softly whipped cream, or a small scoop of vanilla ice cream.
I wouldn’t cover them with a heavy sauce — the blueberry, lemon, cheesecake and crumble layers should remain the stars.
Conclusion
These Lemon Blueberry Cheesecake Bars have everything I want in a fruit cheesecake dessert: a buttery crust, smooth lemon cheesecake, juicy blueberries and a golden crumbly topping.
They’re rich without being overly heavy, and the fresh lemon-blueberry combination makes them especially good for spring and summer. Make them the night before, chill thoroughly, and you’ll have beautiful cheesecake bars ready to slice and serve.
