These No Bake Blueberry Swirl Cheesecake Bars combine the creamy tang of cheesecake with the bright flavor of blueberries. Set on a crunchy Biscoff cookie crust and topped with a luscious homemade blueberry swirl, they make an impressive dessert that is surprisingly simple to prepare. Perfect for making ahead, they come together without any baking, which is ideal when you want to keep things easy but delicious.
I first tried these bars on a lazy weekend when I wanted something special yet simple. Now, they are my go-to dessert for gatherings because everyone loves that glossy swirl and creamy filling.
Ingredients
- Blueberries: frozen is best for a deep purple color and consistent quality
- Light brown sugar: adds subtle caramel notes to the crust and balances the blueberry sweetness
- Unsalted butter: melted to bind the crust without overpowering flavors, use at room temperature for smooth mixing
- Soft spreadable cream cheese: avoids the usual softening hassle and keeps the filling creamy without lumps
- Heavy cream or double cream: whipped to stiff peaks to stabilize the filling and add lightness
- Powdered sugar: helps stabilize the whipped cream for a smooth cheesecake texture
- Vanilla extract: adds warmth and depth to balance the fruitiness of the blueberry swirl
- Egg: used in the blueberry curd to thicken and give silkiness, room temperature is ideal for even cooking
- Lemon juice: fresh or bottled provides brightness that enhances the blueberry flavor
- Biscoff cookie crumbs: forms a flavorful, rich, caramelized base, graham cracker crumbs can be substituted if necessary
Step-by-Step Instructions
Sauté the Aromatics
- Make the Blueberry Sauce for the Swirl:
- Heat blueberries with sugar and lemon juice over medium heat until sugar dissolves and blueberries soften. Blend the mixture smooth, then strain it to remove skins. Whisk an egg separately, then slowly add to the warm blueberry liquid off the heat while whisking continuously. Return to medium heat and stir until thick enough to coat the back of a spoon. Remove from heat and stir in butter until melted. Let cool completely.
Sauté the Aromatics
- Prepare the Crust:
- Combine Biscoff cookie crumbs with packed light brown sugar and melted unsalted butter until mixture is moist and packable. Press firmly and evenly into the base of an 8-inch square pan lined with parchment paper. Chill in the fridge while preparing the filling.
Develop Flavor Base
- Make the Cheesecake Filling:
- In one bowl, beat heavy cream, powdered sugar, and vanilla extract to stiff peaks. In another bowl, whisk cream cheese and granulated sugar until smooth. Gently fold the whipped cream into the cream cheese mixture to create a thick, smooth batter.
Build the Layers
- Assemble the Bars:
- Spread the cheesecake filling evenly over the chilled crust. Dollop about two thirds of the blueberry sauce across the top. Use a kitchen knife to lightly swirl the sauce through the filling, creating a natural marbled effect. Pipe the remaining blueberry curd in thin diagonal lines, then use a toothpick held at an angle to swirl the lines gently, being careful not to over-mix.
Finish and Chill
- Chill Until Set:
- Place the prepared pan in the refrigerator and chill for at least four hours or overnight until firm.

My favorite ingredient in this recipe is the blueberry curd swirl. It not only provides that gorgeous vibrant color but gives each bite a tangy pop against the creamy filling. I remember making these bars for a summer picnic when the blueberries were at their peak. Everyone was enchanted by the beautiful marbling and kept asking for seconds.
Storage Tips
Store the cheesecake bars in a sealed container in the refrigerator to keep them fresh. Avoid pressing plastic wrap directly against the surface, as it can stick to the blueberry swirl and disrupt the beautiful pattern. Do not stack bars on top of each other since they are soft and can distort under pressure. For longer storage, slice the cheesecake bars before freezing. Flash freeze the pieces on a tray to firm up, then transfer them to an airtight container or freezer bag. They keep well for up to three months and defrost evenly in the fridge.
Ingredient Substitutions
If you cannot find Biscoff cookies, graham cracker crumbs or crushed golden Oreos work well for the crust and will give different but delicious flavors. For cream cheese, block cream cheese can be used but soften it fully beforehand to avoid lumps. Instead of making blueberry curd, you can use cream cheese combined with blueberry jam for a quicker swirl, but the texture will be less silky. Light brown sugar can be replaced with granulated sugar if needed, just know that the caramel notes in the base will be milder.
Serving Suggestions
These cheesecake bars pair wonderfully with a dollop of fresh whipped cream and a handful of fresh blueberries for extra freshness. A light drizzle of lemon zest-infused honey on top adds a fragrant brightness. Serve chilled straight from the fridge on their own or as part of a dessert platter featuring other berry treats or citrus-flavored bites. They also pair beautifully with a chilled glass of sparkling rosé or a bright cup of green tea.
Pro Tips
- Pipe thin diagonal lines of blueberry curd for better swirling instead of dolloping large blobs
- Use a toothpick or skewer at about 45 degrees angle to gently swirl the curd without overmixing
- Run your knife under hot water and wipe clean between cuts for neat bar slices
Common Recipe Questions
- → How long do the cheesecake bars stay fresh?
Keep refrigerated, these bars hold their creamy texture for up to 3 days before the filling starts drying out and separating from the crust.
- → Can I freeze the blueberry swirl bars?
Yes, they freeze well. Slice first, then flash freeze to set before storing in a freezer-safe container. Enjoy within 3 months for best flavor.
- → What helps the blueberry swirl hold its shape?
The blueberry curd is gently cooked with egg and butter to thicken. Cooling it well before swirling ensures it holds distinct patterns without blending into the filling.
- → How can I get clean slices from these creamy bars?
Chill bars thoroughly, cut with a sharp knife straight down, cleaning the blade with warm water between cuts to prevent dragging or smearing.
- → Are substitutions possible for the crust?
Absolutely. Substitute Biscoff crumbs with graham cracker or Oreo cookie crumbs for a different but equally delicious base.
- → What type of cream cheese works best?
Soft spreadable full-fat cream cheese from the fridge blends easiest, avoiding the need for softening and ensuring a smooth filling.
