These blueberry cheesecake bars have a buttery graham cracker crust, smooth vanilla filling and colourful swirls of fresh blueberry sauce. A little lemon brightens the berries and balances the rich cream cheese.
The bars are easier to portion and transport than a full cheesecake. Prepare them ahead for summer parties, picnics, Mother’s Day or family celebrations.

Ingredient Notes
Cream cheese: Use full-fat block cream cheese for the smoothest, most stable filling.
Blueberries: Fresh or frozen berries work in the cooked sauce. Frozen berries may require additional cooking time.
Sour cream: Adds moisture and balances the richness.
Eggs: Add the eggs at low speed to avoid incorporating excess air.
Graham crackers: Process them into fine crumbs for a crust that cuts cleanly.
How to Make Blueberry Cheesecake Bars
Step 1: Make the Blueberry Sauce
Place the blueberries, sugar and lemon juice in a small saucepan.
Cook over medium heat until the berries release their juice and begin to break down.
Combine the cornstarch and water, then stir the mixture into the berries. Cook for another 1–2 minutes, until thick and glossy.
Transfer the sauce to a bowl and cool completely.
Step 2: Prepare the Pan
Preheat the oven to 325°F.
Grease and line a 9-inch square metal pan with parchment paper, leaving an overhang on two sides.
Step 3: Make the Crust
Combine the graham cracker crumbs, sugar, melted butter and salt.
Press the mixture firmly and evenly into the pan.
Bake for 8–10 minutes, then allow it to cool slightly.
Step 4: Beat the Cream Cheese
Beat the softened cream cheese on medium-low speed until completely smooth.
Add the sugar and mix until combined.
Scrape the bowl thoroughly.
Step 5: Add the Remaining Filling Ingredients
Mix in the sour cream, vanilla, lemon zest and salt.
Add the eggs one at a time on low speed.
Stop mixing as soon as the filling becomes smooth.
Step 6: Fill the Crust
Pour the cheesecake mixture over the prepared crust.
Spread it evenly with an offset spatula.
Step 7: Add the Blueberry Swirl
Drop small spoonfuls of cold blueberry sauce across the filling.
Drag a thin knife or skewer gently through the sauce to create loose swirls.
Avoid mixing it completely into the cheesecake.
Step 8: Bake
Bake at 325°F for approximately 35–42 minutes.
The edges should look set while the centre retains a slight movement.
Do not wait until the entire surface becomes firm.
Step 9: Cool and Chill
Cool the bars completely at room temperature.
Cover and refrigerate for at least 4 hours, preferably overnight.
Step 10: Slice
Lift the cold slab from the pan using the parchment.
Cut it into 16 bars with a warm, dry knife, cleaning the blade between cuts.
Tips for Creamy Cheesecake Bars
- Bring the cream cheese, eggs and sour cream to room temperature.
- Beat the cream cheese until smooth before adding other ingredients.
- Mix the eggs on low speed.
- Use completely cooled blueberry sauce.
- Avoid overbaking.
- Chill overnight for the cleanest cuts.
Why Did My Cheesecake Crack?
Cracks can result from overmixing, overbaking or cooling the cheesecake too quickly.
Mix gently after adding the eggs and remove the bars while the centre still moves slightly. Cool them gradually at room temperature before refrigeration.
Why Is the Filling Lumpy?
The cream cheese was probably too cold. Allow it to soften completely and beat it alone before adding the sugar and eggs.
Easy Variations
Lemon Blueberry Cheesecake Bars
Increase the lemon zest and add a small quantity of lemon juice to the filling.
Mixed-Berry Cheesecake Bars
Combine blueberries with raspberries or strawberries.
Chocolate Blueberry Cheesecake Bars
Use a chocolate biscuit crust and finish with dark chocolate drizzle.
Mini Blueberry Cheesecakes
Divide the crust and filling between lined muffin cups and reduce the baking time.
Storage and Freezing
Refrigerate the bars in an airtight container for up to five days.
To freeze, arrange chilled bars in a freezer-safe container with parchment between the layers. Freeze for up to two months and thaw overnight in the refrigerator.
Frequently Asked Questions
Can I use frozen blueberries?
Yes. Add them directly to the saucepan and cook until the sauce becomes thick.
Do I need a water bath?
No. The smaller, shallower filling does not require one.
Can I use spreadable cream cheese?
No. Its higher moisture content can make the filling too soft.
How many bars does the recipe make?
The recipe makes 16 standard bars or 25 small party squares.
