There’s something about the pairing of tart lemon and sweet blueberries that feels like sunshine captured in dessert form. It’s bright without tipping into sour, sweet without turning cloying, the kind of flavor combination that tastes exactly like the moment summer hits its stride. These lemon blueberry cheesecake bars bottle up that feeling in a creamy, citrusy filling swirled with juicy blueberries, all resting on a buttery graham cracker crust.

How to Make Lemon Blueberry Cheesecake Bars
Work through the swirl first so it has time to cool, then move on to the crust and filling while it sits.
Step 1: Make the Blueberry Swirl
Combine the blueberries, sugar, and lemon juice in a small saucepan over medium heat. Cook for 4 to 5 minutes, stirring occasionally and gently mashing some of the berries, until they release their juices. Whisk the cornstarch and water together, then stir into the saucepan. Cook for another minute until thickened and glossy. Remove from heat and let cool completely.
Step 2: Prep the Pan and Oven
Preheat your oven to 325°F. Line an 8×8 or 9×9-inch baking pan with parchment paper, leaving an overhang on two sides so you can lift the bars out cleanly later.
Step 3: Build the Crust
Mix the graham cracker crumbs, sugar, melted butter, and salt in a bowl until the texture resembles wet sand. Press it firmly and evenly into the bottom of your prepared pan using the back of a measuring cup. Bake for 8 to 10 minutes, then set aside to cool slightly.
Step 4: Make the Cheesecake Filling
Beat the softened cream cheese and sugar together until completely smooth, about 2 minutes. Add the eggs one at a time, mixing just until combined after each addition. Stir in the lemon zest, lemon juice, and vanilla, then fold in the sour cream last. Avoid overmixing once the eggs go in, since too much air can cause the bars to puff and crack.
Step 5: Swirl and Bake
Pour the cheesecake filling over the cooled crust and smooth the top. Dollop spoonfuls of the cooled blueberry mixture evenly over the surface, then drag a knife or skewer through in loose figure-eight motions to create a marbled swirl. Bake for 35 to 40 minutes, until the edges are set but the center still has a slight jiggle.
Pro tip: Don’t overswirl. A few confident drags of the knife give you a beautiful marbled effect, while too much stirring blends the colors together and mutes that bakery-style look.
Step 6: Cool and Chill
Let the bars cool at room temperature for about an hour, then refrigerate for at least 4 hours, ideally overnight. This chilling time is what gives you clean, sliceable bars instead of a soft, gooey center.
Run your knife under hot water and wipe it dry between cuts for the cleanest possible edges.

Frequently Asked Questions
Can I use frozen blueberries in this lemon blueberry cheesecake bars recipe?
Yes, and there’s no need to thaw them first. Frozen berries work directly in the saucepan for the swirl, though the cooking time may run a minute or two longer since they release more liquid.
Why did the swirl in my lemon blueberry cheesecake bars sink or disappear?
This usually happens if the blueberry mixture is still warm when it goes on top, or if it’s overmixed into the filling. Let the swirl cool completely first, and use a light hand when dragging the knife through.
Can I make lemon blueberry cheesecake bars ahead of time?
Absolutely. These actually taste better after chilling overnight, once the lemon and blueberry flavors have had time to settle into the filling. That makes them an easy make-ahead choice for parties or busy weeks.
Can I use bottled lemon juice instead of fresh for this recipe?
Fresh is recommended for the best flavor, especially since you’ll need the zest anyway. Bottled juice works in a pinch, but you’ll lose the bright, aromatic quality that fresh lemon zest brings to the filling.
