Prep & Cook Time
- Prep Time: 25 minutes
- Cook Time: 10 minutes
- Total Time: 35 minutes (plus at least 4 hours to chill)
- Servings: 16 bars
Ingredients
- 1 cup fresh blueberries
- ¼ cup granulated sugar
- 1 Tablespoon lemon juice
- 12 sheets graham crackers
- 3 Tablespoons granulated sugar
- 6 Tablespoons salted butter
- ½ cup heavy cream
- 1½ cups cream cheese (cool room temperature)
- ⅛ cup sour cream
- ½ cup granulated sugar
- 1 Tablespoon lemon zest
- ¾ teaspoon vanilla
- 2¼ teaspoons lemon juice
Instructions
- Make the blueberry sauce: In a small saucepan over medium heat, combine 1 cup fresh blueberries, ¼ cup granulated sugar, and 1 Tablespoon lemon juice. Cook for 7-10 minutes, stirring and mashing the berries frequently, until the mixture has thickened into a sauce. Remove from heat and let cool completely.
- Prepare the crust: In a food processor, pulse the 12 sheets of graham crackers into fine crumbs. Add 3 Tablespoons granulated sugar and pulse to combine. Melt the 6 Tablespoons of salted butter and pour over the crumb mixture. Pulse until the mixture resembles wet sand.
- Press the crust mixture firmly and evenly into the bottom of an 8×8-inch baking dish lined with parchment paper. Place in the freezer to set while you make the filling.
- Make the cheesecake filling: Using a hand mixer or stand mixer with the whisk attachment, whip the ½ cup heavy cream on medium-high speed until stiff peaks form. Transfer the whipped cream to a separate bowl and set aside.
- In the same mixing bowl (no need to clean it), beat the 1½ cups cream cheese, ⅛ cup sour cream, and ½ cup granulated sugar on medium speed until completely smooth and creamy, about 2 minutes.
- Add the 1 Tablespoon lemon zest, ¾ teaspoon vanilla, and 2¼ teaspoons lemon juice to the cream cheese mixture. Beat on low speed just until incorporated.
- Using a rubber spatula, gently fold the reserved whipped cream into the cream cheese mixture until no white streaks remain.
- Assemble the bars: Remove the crust from the freezer. Spread the cheesecake filling evenly over the crust.
- Drop dollops of the cooled blueberry sauce over the cheesecake layer. Use a knife or toothpick to gently swirl the sauce into the filling, creating a marbled pattern.
- Cover the dish and refrigerate for at least 4 hours, or preferably overnight, until the filling is completely firm. Lift the bars out using the parchment paper, slice into squares, and serve.
Variations
- Frozen Berry Swap: Substitute frozen blueberries for the fresh ones in the sauce; you may need to add an extra minute of cooking time.
- Different Swirl: Instead of swirling, gently fold half of the cooled blueberry sauce directly into the cheesecake filling for a uniform purple hue and berry flavor in every bite.
- Layered Presentation: For a cleaner look, spoon the cheesecake filling into a piping bag and pipe it over the crust before swirling in the sauce.
- Individual Servings: Press the crust into the bottoms of muffin tins lined with paper liners to create individual no-bake mini cheesecakes.
Tips for Success
- Ensure your cream cheese is at a cool room temperature for a perfectly smooth, lump-free filling.
- For clean slices, dip your knife in hot water and wipe it dry between each cut.
- Let the blueberry sauce cool completely before swirling it in; if it’s warm, it will melt the cheesecake filling and become difficult to swirl.
- For the best flavor and texture, allow the bars to chill overnight in the refrigerator.
Storage & Reheating
Store the bars in an airtight container in the refrigerator for up to 5 days. They can also be frozen for up to 2 months; thaw overnight in the refrigerator before serving. This dessert is served cold and should not be reheated.
FAQ
Can I use frozen blueberries?
Yes, you can use frozen blueberries for the sauce. There’s no need to thaw them first; just cook them directly from frozen, possibly adding a minute or two to the cooking time.
Can I use unsalted butter?
Yes. If using unsalted butter, consider adding a tiny pinch of salt to the crust mixture to balance the sweetness.
My filling is too soft to slice. What happened?
The bars likely did not chill long enough. The filling needs a minimum of 4 hours to fully set, and overnight is ideal. Also, ensure you whipped the heavy cream to stiff peaks for maximum stability.
Can I use a different pan?
Yes, a 9×9-inch pan will work, but the bars will be slightly thinner. The chilling time may be slightly less. For a thicker bar, stick with the 8×8-inch pan.
What can I use instead of a food processor for the crust?
Place the graham crackers in a heavy-duty zip-top bag and crush them finely with a rolling pin. Then, mix the crumbs with the sugar and melted butter in a bowl.
Can I make these ahead of time?
Absolutely. These bars are an excellent make-ahead dessert. They keep well in the fridge for several days and their flavor improves as it chills.
