Blackberry Cream Cheese Bars (or Blackberry Jamboree bars) are one of those desserts that feel a little special without being fussy. You get a buttery pecan crust, a light and creamy filling, and a sweet-tart blackberry topping that makes every bite pop. They’re the kind of chilled dessert that works just as well for a summer get-together as it does for a simple make-ahead treat. If you’ve already tried my Blueberry Cream Cheese Bars (copycat Blueberry Jamboree), I think you will love this blackberry version, too!
Ingredients & Substitutions
- Blackberries: I prefer fresh blackberries for this recipe since they hold their shape better when folded into the topping. You can use frozen berries if needed; just thaw them first and drain off any excess liquid.
- Granulated Sugar + Brown Sugar: This combination adds sweetness with a little extra depth from the brown sugar. If you only have granulated sugar, that will work, but the flavor will be slightly lighter.
- Cornstarch: Cornstarch is mixed with cold water to make a slurry. This is added to the blackberry mixture to thicken it. (If added directly to the hot berries, it can clump.)
- Lemon Zest: Adds a fresh, bright flavor that balances the sweetness. Be sure to wash the lemon well before zesting. If needed, you can substitute with a small splash of lemon juice.
- Crust: This simple crust is made with toasted pecans, melted butter, and all-purpose flour for a buttery, slightly nutty base that holds together well. Toasting the pecans brings out their flavor. Use finely chopped pecans to save time, or substitute walnuts if needed. The melted butter binds everything together, and all-purpose flour gives the crust structure, so it slices cleanly after baking.
- Heavy Cream: Also known as heavy whipping cream, this type contains sufficient fat to whip into stiff peaks. It creates a light, airy texture in the filling. Make sure it is cold before whipping.
- Confectioners’ Sugar: Sweetens the filling and blends in smoothly without any graininess. This also helps stabilize the whipped cream. Granulated sugar is not recommended.
- Cream Cheese: Adds richness and a slight tang to balance the sweetness. Be sure it is fully softened before mixing so the filling turns out smooth and creamy. Full-fat works best for the most stable texture.
FAQs
Can I use frozen blackberries instead of fresh?
Yes, frozen blackberries work well in this recipe. Just thaw them first and drain any excess liquid so the topping doesn’t become too thin.
How long do I need to chill blackberry cream cheese bars?
For best results, chill for at least 4 hours, but overnight is ideal. This helps the filling fully set so you get clean, neat slices.
Can I make Blackberry Cream Cheese Bars ahead of time?
Yes, these are a great make-ahead dessert. You can prepare them the day before serving and keep them refrigerated until ready to slice.
Do I have to toast the pecans?
Technically, no, but I highly recommend it. Toasting brings out a deeper, nuttier flavor and makes the crust taste richer. If you’re short on time, you can skip it and still get a good result.
Can I use a different nut in the crust?
Yes, walnuts are the best substitute for pecans. They give a similar texture and toast nicely for added flavor.
Can I freeze Blackberry Cream Cheese Bars?
Yes, they freeze well. Slice into squares and wrap tightly or store in an airtight container. Freeze for up to 2 months, then thaw in the refrigerator overnight before serving.
Why is my filling soft or not setting properly?
This usually means the bars haven’t chilled long enough. Make sure they chill for at least 4 hours (overnight is best) so the filling can fully firm up before slicing.
How to Serve Blackberry Cream Cheese Bars
These Blackberry Jamboree are best served well chilled, straight from the refrigerator. The creamy filling and jammy blackberry topping hold their structure beautifully when cold, making them easy to slice into clean, bakery-style squares.
For serving, I like to cut them into smaller squares since they’re rich and layered. A sharp knife works best, and wiping it clean between cuts helps keep the edges neat. You can also add a light dusting of confectioners’ sugar or a few fresh blackberries on top for a simple finishing touch.
How to Store Blackberry Cream Cheese Bars
Refrigerator: Store Blackberry Cream Cheese Bars covered in the refrigerator for up to 4 to 5 days. Keep them chilled right up until serving, since the filling is soft and creamy.
Freezer: These bars also freeze well. For best results, cut into squares and wrap tightly or place in an airtight container. Freeze for up to 2 months. Thaw overnight in the refrigerator before serving for the best texture.
Make-Ahead Tip: These are ideal for prepping ahead since the texture actually improves after a full chill. Just wait to slice until fully set for the cleanest edges.
Blackberry Cream Cheese Bars
Ingredients
Blackberry Topping
- 4 cups (580 g) fresh blackberries, divided
- ½ cup (50 g) granulated sugar
- 3 tablespoons brown sugar
- 2 tablespoons cornstarch
- 2 tablespoons water
- 1 teaspoon lemon zest
Crust
- 1 cup (110 g) toasted pecans, finely chopped
- ¾ cup (1 ½ sticks / 170 g) unsalted butter, melted
- 2 cups (240 g) all-purpose flour
Filling
- 2 cups (476 g) heavy cream
- 2 cups (220 g) confectioners' sugar
- 2 packages (8 ounces each) cream cheese, room temperature
Instructions
- Preheat oven to 325°F. Line a 9×13-inch baking dish with parchment paper, leaving some overhang for easy removal. Set aside.
Blackberry Topping
- In a large saucepan over medium-high heat, add 2 ½ cups of blackberries, granulated sugar, and brown sugar. Stir until the sugar dissolves and the berries begin to release their juices and soften.
- In a small bowl, whisk together the cornstarch and water until smooth. Pour the mixture into the saucepan and continue stirring until thickened to a jam-like consistency that coats the back of a spoon.
- Remove from heat and stir in the lemon zest. Gently fold in the remaining blackberries.
- Transfer the mixture to a bowl and let it cool slightly, then place it in the refrigerator to chill while you prepare the crust and filling.
Crust
- To toast the pecans, add them to a medium skillet over medium heat. Cook, stirring frequently, until fragrant and lightly browned, about 3 to 5 minutes. Remove from heat and let cool.
- When ready, in a medium bowl, combine melted butter, flour, and toasted pecans. Mix until evenly combined.
- Press the mixture firmly into the bottom of the prepared baking dish.
- Bake 15 minutes. Remove from the oven and let cool to room temperature.
Filling
- Add heavy cream to a mixing bowl. Start mixing at the lowest speed, and then gradually increase speed to medium until the cream starts to get thicker. (The gradual progression prevents you from spraying yourself with cream.)
- When the cream starts to thicken, stop the mixer. Slowly add in the confectioners’ sugar and then resume mixing again, starting with low speed and increasing to medium speed, and eventually moving to a high speed. The cream will thicken and start to peak.
- In a separate large bowl, add cream cheese and beat until creamy.
- Gently fold the whipped cream mixture into the cream cheese.
- Spread the filling evenly over the cooled crust.
- Spoon the chilled blackberry topping over the filling and gently spread it into an even layer.
- *Top with more blackberries if you would like. (I added some extra in my images.)
- Cover and refrigerate for at least 4 hours, or until fully set. For best results, chill overnight before slicing and serving.
