Blueberry Cheesecake Bars with Buttery Crumb Topping

Blueberry Cheesecake Bars combine everything you love about classic cheesecake in an easy-to-slice dessert. They feature a buttery graham cracker crust, smooth cream cheese filling, juicy blueberries, and a golden crumb topping.
Instead of preparing a traditional round cheesecake, this recipe uses a square baking pan to create individual bars. The crust provides a firm base, the cheesecake layer adds a creamy texture, and the blueberry mixture brings fruity flavor to every bite. A buttery crumble finishes the dessert with a sweet, slightly crisp topping.
These bars take about 15 minutes of preparation and around 45–55 minutes to bake. After cooling and chilling, they can be sliced and served as a dessert for family gatherings, celebrations, or a simple homemade treat.

Ingredients You’ll Need

Graham Cracker Crust

Graham cracker crumbs, sugar, and melted butter form the base. Pressing the mixture firmly into the pan helps create a sturdy crust beneath the filling.

Cheesecake Filling

Softened cream cheese is the main ingredient in the cheesecake layer. Sour cream adds a creamy texture, while sugar and vanilla provide sweetness and flavor. Cornstarch helps thicken the filling, and eggs help it set during baking.

Blueberry Filling

Two cups of blueberries provide the fruit layer. Lemon juice adds brightness, while sugar sweetens the berries. Cornstarch helps thicken the mixture as it bakes. Lightly mashing a small portion of the blueberries releases some of their juices.

Buttery Crumb Topping

All-purpose flour, granulated sugar, light brown sugar, and melted butter create a sweet crumb topping. Chilling the mixture while preparing the other components helps keep it ready for assembly.

How to Make Blueberry Cheesecake Bars

Step 1: Prepare the Pan

Preheat the oven to 350°F (175°C). Line a 9-by-9-inch baking pan with parchment paper, leaving some overhang on the sides. This makes it easier to lift the bars out after baking and cooling.

Step 2: Make the Graham Cracker Crust

In a bowl, combine the graham cracker crumbs and sugar. Add the melted butter and mix with a fork until the crumbs are evenly moistened and resemble wet sand.
Press the mixture firmly into the bottom of the prepared pan. Place the pan in the refrigerator while preparing the other layers.

Step 3: Prepare the Crumb Topping

In a separate bowl, stir together the all-purpose flour, granulated sugar, and light brown sugar. Add the melted butter and mix until coarse crumbs form. Refrigerate the topping until needed.

Step 4: Mix the Cheesecake Filling

Beat the softened cream cheese, sugar, and vanilla until smooth. Add the sour cream and cornstarch, mixing until combined.
Add the eggs and mix just until incorporated. Avoid overmixing so the filling remains smooth.

Step 5: Prepare the Blueberries

Place about 3–4 tablespoons of the blueberries in a bowl and lightly mash them with a fork.
Add the remaining blueberries, lemon juice, sugar, and cornstarch. Stir gently until the ingredients are evenly combined.

Step 6: Assemble the Layers

Spread the cheesecake filling evenly over the chilled graham cracker crust.
Spoon the blueberry mixture over the cheesecake layer and gently spread it out. Sprinkle the prepared crumb topping evenly across the blueberries.

Step 7: Bake

Bake at 350°F (175°C) for about 45–55 minutes, or until the center is set. Begin checking after 35 minutes, and tent the pan with foil if the topping starts browning too quickly.
The bars may puff up slightly during baking and then settle as they cool.

Step 8: Cool and Chill

Let the bars cool in the pan for about 30 minutes. Use the parchment overhang to lift them out of the pan.
Allow them to cool completely, then refrigerate for at least a few hours before slicing. Chilling helps the cheesecake filling firm up and makes the bars easier to cut neatly.

Tips for the Best Blueberry Cheesecake Bars

• Soften the cream cheese: Softened cream cheese blends more easily and helps prevent lumps in the filling.
• Avoid overmixing the eggs: Mix just until incorporated to keep the cheesecake filling smooth.
• Chill the crust: Refrigerating the crust while preparing the other components helps it firm up before assembly.
• Keep the crumb topping cold: Refrigerate it until you are ready to sprinkle it over the blueberries.
• Mash only a few berries: Lightly mashing 3–4 tablespoons releases some juice without crushing all the blueberries.
• Watch the topping as it bakes: Start checking after 35 minutes and cover loosely with foil if it browns too quickly.
• Chill before slicing: Let the bars cool completely and refrigerate them for at least a few hours for cleaner slices.

Variations and Substitutions

Use Frozen Blueberries

The supplied recipe does not specify whether frozen blueberries are suitable. For the most predictable result, use the listed blueberries and avoid changing the quantity of fruit or thickener without adjusting the recipe.

Cut Smaller or Larger Bars

Cut the chilled dessert into 12–16 portions, depending on your preferred serving size. Smaller pieces are useful for dessert platters, while larger bars make more generous portions.

Adjust the Crumb Topping

The topping uses both granulated and light brown sugar for sweetness and flavor. Keep both ingredients for the recipe’s intended crumb texture.

When to Serve Blueberry Cheesecake Bars

These bars are a lovely choice for family desserts, gatherings, potlucks, and celebrations. Their individual portions make them easy to arrange on a serving plate, and the blueberry layer gives them a colorful finish.
For the best presentation, wait until the bars are completely chilled before cutting them. Wipe the knife between slices if you want the layers to look especially neat.
