Full Ingredients

Raspberry Swirl

• 1 cup (120 g) fresh or frozen raspberries
• 2 tablespoons (25 g) granulated sugar
• 1 teaspoon fresh lemon juice
• 1 teaspoon cornstarch
• 1 teaspoon water (for mixing with cornstarch, if needed)

Buttery Shortbread Base

• 1 1/2 cups (195 g) all-purpose flour
• 1/3 cup (70 g) granulated sugar
• 1/4 teaspoon fine salt
• 3/4 cup (170 g) unsalted butter, cold and cut into small cubes
• 1 teaspoon vanilla extract (optional, for extra flavor)

Vanilla Cheesecake Layer

• 16 ounces (454 g) full-fat cream cheese, at room temperature
• 2/3 cup (135 g) granulated sugar
• 1/4 cup (60 g) sour cream, at room temperature
• 2 large eggs, at room temperature
• 1 teaspoon vanilla extract
• 1 teaspoon finely grated lemon zest (optional but recommended for brightness)
• 1/8 teaspoon fine salt

Step-by-Step Instructions

Step 1: Prepare the pan and preheat the oven

Preheat your oven to 325°F (163°C). Line a 9×9-inch (23×23 cm) square baking pan with parchment paper, leaving an overhang on two opposite sides to create a sling. This will make it easy to lift the bars out later. Lightly grease any exposed sides of the pan. Set the pan aside while you make the raspberry swirl and shortbread base.

Step 2: Make the raspberry swirl

In a small saucepan, combine the raspberries, sugar, and lemon juice. Place over medium heat and cook, stirring occasionally, until the berries break down and release their juices, about 3–5 minutes. In a small bowl, stir the cornstarch with 1 teaspoon of water (if needed) to make a smooth slurry, then stir it into the raspberry mixture. Continue to simmer for 1–2 minutes, stirring, until the sauce thickens slightly and looks glossy. Remove from the heat and press through a fine-mesh sieve into a bowl if you prefer a smooth swirl (optional), or leave the seeds for extra texture. Let the raspberry mixture cool to room temperature while you prepare the crust and filling.

Step 3: Make the buttery shortbread base

In a medium bowl, whisk together the flour, sugar, and salt. Add the cold, cubed butter and, if using, the vanilla extract. Using a pastry cutter, two knives, or your fingertips, cut the butter into the dry ingredients until the mixture looks like coarse, damp sand with a few pea-sized bits of butter remaining. It should hold together when you squeeze a small handful. Tip the mixture into the prepared pan and press it firmly and evenly into the bottom using your fingers or the flat bottom of a measuring cup. Try to compact it well so it bakes up crisp and sturdy. Bake for 15–18 minutes, until the edges are lightly golden and the surface looks set. While the crust bakes, make the cheesecake filling.

Step 4: Prepare the vanilla cheesecake filling

In a large mixing bowl, beat the room-temperature cream cheese with a hand mixer (or stand mixer fitted with the paddle attachment) on medium speed for 1–2 minutes, until completely smooth and fluffy, with no lumps. Scrape down the sides and bottom of the bowl. Add the sugar and salt and beat again until well combined and creamy. Mix in the sour cream, vanilla extract, and lemon zest (if using) until smooth. Finally, add the eggs one at a time, mixing on low speed just until each egg is incorporated. Avoid overbeating once the eggs are in; too much air can cause the cheesecake layer to puff and crack. Scrape the bowl again to make sure everything is evenly mixed.

Step 5: Assemble with the raspberry swirl

When the shortbread crust is done, remove it from the oven but leave the oven on at 325°F (163°C). Let the crust cool for 5 minutes so it is no longer bubbling hot, but still warm. Give the cheesecake batter a final gentle stir, then pour it over the warm crust and smooth the top with a spatula. Spoon small dollops (about 1 teaspoon each) of the cooled raspberry sauce all over the surface of the cheesecake layer. Using a thin knife, toothpick, or skewer, gently drag through the dollops in a swirling motion to create pretty marbled patterns. Try not to over-swirl or you will lose the contrast between raspberry and vanilla.

Step 6: Bake the cheesecake bars

Return the pan to the oven and bake for 25–30 minutes, or until the edges are set and the very center still has a slight wobble when you gently jiggle the pan. The top should look mostly set and not wet, with just a bit of jiggle in the middle. If you see large bubbles forming, you can tap the pan gently on the oven rack to release them. Avoid overbaking; the bars will continue to firm up as they cool. Remove the pan from the oven and place it on a wire rack.

Step 7: Cool, chill, and slice

Let the bars cool in the pan at room temperature for about 1–1 1/2 hours, until no longer warm. Then cover the pan and transfer it to the refrigerator to chill until very cold and fully set, at least 3 hours or overnight for the cleanest slices. Once chilled, use the parchment sling to lift the slab of cheesecake out of the pan and onto a cutting board. For neat edges, run a long, sharp knife under hot water, wipe it dry, and cut straight down into 16 squares (4 by 4). Wipe and re-warm the knife between cuts. Garnish with fresh raspberries, a light dusting of powdered sugar, or a few mint leaves if you like, and serve chilled.

Pro Tips

• Room-temperature dairy is key: cold cream cheese or eggs can lead to a lumpy batter. Let them sit out 30–45 minutes before starting.
• Do not rush the chilling time; the bars slice best and taste creamiest when fully cold.
• If using frozen raspberries, there is no need to thaw first—just cook them a little longer to reduce extra liquid.
• Press the shortbread firmly into the pan to prevent crumbling when you slice the bars.
• Swirl gently; a few big, bold swirls look prettier than lots of tiny ones that muddle the colors.

Variations

• Lemon-Raspberry Cheesecake Bars: Increase the lemon zest in the cheesecake to 2 teaspoons and add an extra teaspoon of lemon juice to the raspberry swirl for an even brighter, tangier flavor.
• Mixed Berry Swirl: Replace the raspberries with a mix of raspberries, blueberries, strawberries, or blackberries (keeping the total at 1 cup) for a more complex berry flavor and a beautiful marbled color.
• Chocolate-Drizzled Bars: Once the chilled bars are cut, drizzle them with melted dark or white chocolate and let it set before serving.

Storage & Make-Ahead

Store the raspberry cheesecake bars in an airtight container in the refrigerator for up to 4–5 days. Separate layers with parchment paper if stacking to protect the swirled tops. For longer storage, freeze the fully cooled and chilled bars on a baking sheet until firm, then wrap each bar tightly in plastic wrap and place in a freezer bag or container for up to 2 months. Thaw overnight in the refrigerator before serving. You can also make the raspberry swirl up to 2 days ahead and keep it covered in the fridge, and bake the bars the day before you plan to serve them for the best texture and flavor.
