Raspberry White Chocolate Bars

These bars happened by accident one summer afternoon when I overstocked on raspberries at the farmer's market and had half a block of cream cheese sitting in my fridge. I'd been craving something between a cheesecake and a shortbread, something that didn't require a springform pan or an hour of my Saturday. What emerged was these jewel-like bars with a crisp buttery base, a cloud of white chocolate cheesecake, and ribbons of tart raspberry running through it all. They've become my go-to when I want dessert that feels fancy but tastes like it came together in my kitchen, not a bakery case.

I brought a batch to my sister's potluck last July, and they disappeared before the main course finished. Someone asked for the recipe, then someone else, and suddenly I was writing it down on the back of a grocery list while standing in her kitchen. That's when I knew these weren't just a happy accident anymore—they'd become something I'd be making for years.

Ingredients

• Graham cracker crumbs (200 g): The foundation needs to taste buttery and toasted, so don't skip the pre-baking step or your crust will taste raw and dusty.
• Unsalted butter (75 g, melted): Melted butter coats every crumb evenly, making the crust bind without needing eggs or extra binders.
• Granulated sugar (2 tbsp for crust, plus 100 g for filling, plus 2 tbsp for raspberries): This recipe uses sugar at three different points, so measure carefully or everything gets too sweet.
• Cream cheese (400 g, softened): Room temperature cream cheese beats in smoothly and won't create lumps that ruin the filling's silky texture.
• Eggs (2 large): Add them one at a time and beat well, or the filling will be dense instead of creamy.
• Vanilla extract (1 tsp): A small amount keeps the focus on the white chocolate and raspberry without making it taste like dessert shop vanilla.
• White chocolate (120 g, melted and cooled): Let it cool before folding into the filling or it'll cook the eggs; white chocolate also needs gentle folding to avoid deflating the mixture.
• Sour cream (60 ml): Adds tang that keeps the bars from tasting cloying and helps the texture stay tender rather than dense.
• Fresh raspberries (150 g): Frozen and thawed work just as well and often have better flavor than fresh in winter months.
• Lemon juice (1 tsp): Brightens the raspberry puree so it doesn't taste flat or one-dimensional against the white chocolate.

Instructions

Heat the oven and prepare your pan:

Set your oven to 175°C (350°F) and line a 22 cm square baking pan with parchment paper, letting it hang over two sides so you can lift the whole thing out later. This takes the guesswork out of cutting and serving.

Build the crust:

Mix graham cracker crumbs with melted butter, sugar, and salt until it looks like wet sand, then press it firmly and evenly into the pan bottom. Bake for 8 minutes until it smells toasted and looks lightly golden, then let it cool while you make the next component.

Cook the raspberry puree:

Combine fresh or thawed raspberries with sugar and lemon juice in a small saucepan and cook over medium heat, stirring and mashing as you go, until the mixture thickens and darkens (about 5 minutes). Push it through a fine mesh sieve to remove the seeds so your swirl stays silky, not gritty.

Make the cheesecake filling:

Beat softened cream cheese and sugar together until completely smooth and creamy, then add eggs one at a time, beating well after each one. Mix in vanilla and sour cream, then gently fold in the cooled melted white chocolate just until combined—overmixing here makes the filling tough.

Assemble and swirl:

Pour the cheesecake filling over the cooled crust and smooth it level. Drop spoonfuls of cooled raspberry puree across the surface, then draw a knife or skewer through the puree in zigzag patterns to create marbled ribbons.

Bake low and slow:

Bake for 25–27 minutes—the center should jiggle just slightly when you shake the pan because it will keep cooking as it cools and firms up in the fridge. Overbaking makes the bars crack and tastes dry.

Chill and cut:

Let the bars cool to room temperature, then refrigerate for at least 2 hours before slicing into 16 squares. The parchment paper overhang lets you lift the whole block out, then you can cut neat bars with a hot, wet knife.

One winter my friend brought these bars to a dinner party and someone at the table paused mid-bite and said, 'Wait, is this cheesecake or fruit or chocolate?' That confusion, that moment of not being able to quite name what you're eating, is exactly when you know a dessert has worked.

Why White Chocolate Works Here

White chocolate usually feels like the lesser cousin at the dessert table, overshadowed by dark and milk chocolate. But here it's essential—it buffers the tartness of raspberries without adding competing flavor, and it melts into the cheesecake filling to create a texture that's almost custardy. The sweetness also balances sour cream, which could otherwise feel too tangy on its own.

Crust Matters More Than You Think

The crust gets pre-baked for a reason: it gives you a toasted, slightly crisp foundation that won't absorb moisture from the filling and turn soggy. If you skip this step or don't bake it long enough, the whole bar falls apart when you try to pull it apart, and you'll end up with beautiful layers that turn into a fork-required mess. The parchment paper overhang isn't just for convenience—it's your insurance policy against disaster.

Making Them Your Own

These bars are a canvas, so don't be afraid to experiment. I've made them with blackberries when raspberries were expensive, added a tablespoon of lemon zest to the filling, and even scattered crushed freeze-dried raspberries on top before baking. The formula stays sturdy as long as you respect the ratio of cream cheese to eggs to white chocolate.

• Add 2 tablespoons of chopped nuts to the crust mixture for crunch that lasts through the cheesecake layer.
• Swap graham crackers for digestive biscuits or vanilla wafers if you want a different flavor foundation.
• Chill the bars for at least 2 hours before serving, but they taste even better after sitting in the fridge overnight when the flavors have melded.

Pin It

These bars sit in my fridge most weeks now, a small reward for being the kind of cook who saves the farmer's market raspberries instead of eating them straight from the container. They're the dessert that makes people ask for the recipe and then actually make it, which is the highest compliment a dessert can receive.

Recipe FAQs

→ How do I achieve a smooth swirl effect?

Gently drop spoonfuls of raspberry puree over the filling and use a knife or skewer to lightly swirl without overmixing.

→ Can I prepare the bars ahead of time?

Yes, chilling the bars for at least 2 hours improves texture and flavor. They can be refrigerated up to 4 days or frozen for 2 months.

→ What is best to replace graham crackers in the crust?

Digestive biscuits or vanilla wafers work well for a slightly different yet still buttery crust base.

→ How to ensure the bars bake properly?

Bake until the center is just set but still slightly jiggly to avoid dry texture and maintain creaminess.

→ Is it possible to add crunch to the crust?

Adding chopped nuts to the crumb mixture before baking adds pleasant crunch and texture contrast.
