Method
Make the crust
- Heat the oven to 325°F.
- Line a 9x13-inch baking pan with parchment paper, leaving overhang on two opposite sides.
- Lightly grease the parchment and exposed sides.
- Stir the graham cracker crumbs and melted butter together until evenly moistened.
- Press the crumb mixture firmly into the bottom of the pan.
- Bake for 10 minutes.
- Cool in the pan for 10 minutes.
Make the raspberry swirl
- Warm the raspberry preserves in a microwave-safe bowl for 10 to 15 seconds, until spoonable.
- Stir the preserves until smooth.
Make the filling
- Microwave the white chocolate in a heatproof bowl at 50% power in 20-second bursts, stirring after each, until smooth.
- Let the white chocolate cool for 5 minutes while remaining fluid.
- Beat the cream cheese and sugar in a large bowl with an electric mixer on medium-low speed until smooth, scraping down the bowl as needed.
- Beat in the sour cream and vanilla.
- Mix in the melted white chocolate until just combined.
- Add the eggs one at a time, mixing on low speed just until each is incorporated.
Assemble and bake
- Spread the filling evenly over the crust.
- Spoon the raspberry preserves in small dollops over the top.
- Gently swirl the preserves through the filling with a knife.
- Bake for 35 to 40 minutes, until the edges are set and the center still has a slight jiggle.
- Cool in the pan on a wire rack for 1 hour.
- Cover and refrigerate for at least 4 hours, until firm.
- Use the parchment overhang to lift the bars from the pan.
- Cut into 16 pieces.
Notes
For neat slices, make sure the bars are fully firm before cutting. Store covered in the refrigerator for up to 5 days; freeze yes, tightly wrapped, for up to 2 months. For a gluten-free swap, use gluten-free graham cracker crumbs.
