Raspberry Swirl Lemon Cheesecake Bars
Yield: 12–16 bars
Pan: 9 × 13-inch / 23 × 33 cm rectangular pan
Prep: 25 minutes
Bake: 35–45 minutes
Chill: at least 4 hours, preferably overnight
Ingredients
1. Buttery biscuit base
2 cups (250 g) all-purpose/plain flour
½ cup (100 g) granulated sugar
½ tsp salt
1 cup (226 g) unsalted butter, melted
1 tsp vanilla extract
2. Creamy lemon cheesecake layer
24 oz (680 g) full-fat cream cheese, softened
1 cup (200 g) granulated sugar
3 large eggs, room temperature
¾ cup (180 g) sour cream
2 tbsp lemon juice
1 tbsp finely grated lemon zest
2 tsp vanilla extract
2 tbsp all-purpose/plain flour
¼ tsp salt
3. Raspberry swirl
1½ cups (185–200 g) fresh or frozen raspberries
¼ cup (50 g) granulated sugar
1 tbsp lemon juice
1 tbsp cornstarch
1 tbsp water
Optional: ½ cup (60–70 g) additional fresh raspberries for scattering over the cheesecake.
Full Method
Step 1 — Prepare the pan
Heat oven to 350°F / 175°C.
Line a 9 × 13-inch pan with parchment paper, leaving some paper hanging over the sides.
Lightly grease the parchment.
The parchment makes it much easier to remove the finished bars.
Step 2 — Make the raspberry sauce
Put into a small saucepan:
1½ cups raspberries
¼ cup sugar
1 tbsp lemon juice
Cook over medium heat for about 4–6 minutes, stirring and crushing the berries.
Mix together:
1 tbsp cornstarch
1 tbsp water
Add this slurry to the raspberries.
Cook for another 1–2 minutes, stirring constantly, until thick.
Remove from heat.
For a smoother swirl
Push the mixture through a fine-mesh sieve to remove the seeds.
For the appearance in your photo
Don’t strain all of it. Keeping some raspberry pieces/seeds gives you those beautiful dark raspberry spots.
Allow the sauce to cool while you make the base.
Step 3 — Make the base
Mix:
250 g flour
100 g sugar
½ tsp salt
Add:
226 g melted butter
1 tsp vanilla
Mix until you have a soft, crumbly dough.
Press firmly into the lined pan.
Important
Compact the mixture well, particularly around the corners. A flat-bottomed glass or measuring cup works very well.
Bake for approximately 15–18 minutes, until the edges are just beginning to turn golden.
Don’t overbake it — it will bake again with the cheesecake layer.
Remove from the oven.
Step 4 — Make the lemon cheesecake
Make sure your cream cheese is softened to room temperature.
Beat the cream cheese and sugar until smooth.
Add eggs one at a time, mixing on low speed just until incorporated.
Add:
sour cream
lemon juice
lemon zest
vanilla
flour
salt
Mix only until smooth.
Don’t overbeat
Once the eggs are added, avoid whipping lots of air into the mixture. Too much air can cause the cheesecake to puff and crack.
Step 5 — Assemble
Pour the cheesecake mixture over the warm or slightly cooled base.
Spread evenly.
Now spoon small amounts of raspberry sauce over the surface.
You want irregular dots and streaks, rather than covering the whole surface.
For a look very close to the photograph:
Add raspberry sauce in small blobs.
Add a few fresh raspberries.
Take a thin knife or skewer.
Drag it through the raspberry blobs in sweeping S-shaped motions.
Don’t swirl too much.
A few large raspberry streaks + smaller raspberry spots will give the homemade marbled appearance shown in your picture.
Step 6 — Bake
Reduce the oven to:
325°F / 165°C
Bake for approximately 30–38 minutes.
The edges should look set while the center still has a gentle wobble.
Don’t wait for the center to become completely firm in the oven.
It will continue cooking as it cools.
Step 7 — Cool completely
Remove from the oven.
Let it cool in the pan for about 1 hour.
Then refrigerate for at least:
4 hours
For the cleanest slices, refrigerate overnight.
How to Get Clean Slices
Use a large sharp knife.
For each cut:
Dip the knife in hot water.
Wipe it dry.
Make one cut.
Wipe the knife.
Repeat.
This produces much cleaner cheesecake bars.
Optional Extra-Raspberry Version
If you want it to look even more like the photograph, use:
200 g raspberries in the sauce
plus 100 g fresh raspberries scattered over the cheesecake
plus a few extra spoonfuls of raspberry sauce for the top
Don’t arrange the berries too neatly. Random clusters give the rustic appearance in the photo.

Look for statements such as “may contain nuts” or “made in a facility that also processes…”
Also use clean bowls, utensils, mixer attachments, cutting boards and baking pans that haven’t been contaminated with nuts.
Peanut allergy
This recipe contains no peanuts, but cross-contact is possible with commercially packaged ingredients.

Recipe Q&A
Can I use frozen raspberries?
Yes. You don’t need to completely thaw them for the raspberry sauce.
Frozen raspberries can actually work extremely well because they’re cooked down into the swirl.
Can I use strawberries?
Yes. Replace the raspberries with approximately 200 g strawberries.
Because strawberries contain more water, cook the sauce a little longer until thick.
Can I use blueberries?
Absolutely. Blueberry-lemon cheesecake bars are excellent using the same method.
Can I make this without nuts?
Yes — the recipe is naturally nut-free, assuming your individual ingredients are free from nut cross-contact.
Can I make it gluten-free?
Yes.
Replace the regular flour in both the base and cheesecake layer with a 1:1 gluten-free baking flour blend.
Make sure the blend is certified gluten-free if you’re preparing it for someone with celiac disease.
Can I make it egg-free?
The cheesecake filling is more difficult to make egg-free because the eggs provide structure.
You can use a tested egg-free cheesecake recipe/filling, but I wouldn’t simply omit the eggs from this recipe.
Can I use low-fat cream cheese?
You can, but full-fat cream cheese is strongly recommended.
Low-fat cream cheese generally produces a softer, wetter cheesecake.
Why did my cheesecake crack?
Usually one or more of these:
Overbaking
Oven temperature too high
Overmixing after adding eggs
Sudden temperature change
Not enough moisture in the filling
A small crack isn’t a problem — the raspberry swirl hides imperfections beautifully.
Why is the center still wobbly?
That’s actually what you want.
When you take it out, the center should have a soft jiggle, not behave like liquid.
It firms considerably during refrigeration.
Why is my cheesecake runny?
The most common causes are:
It wasn’t baked long enough.
It wasn’t chilled long enough.
Too much liquid was added.
Low-fat cream cheese was used.
It was cut before completely chilled.
Give it at least 4 hours in the refrigerator, preferably overnight.
Can I make it ahead?
Yes — and it’s better the next day.
Make it the day before serving and keep refrigerated.
How long does it keep?
Covered in the refrigerator:
3–4 days for best quality.
Don’t leave cheesecake sitting at room temperature for extended periods.
Can I freeze it?
Yes.
Cut into individual bars, wrap well and freeze for up to approximately 2 months for best quality.
Thaw overnight in the refrigerator.
Can I add white chocolate?
Yes. White chocolate pairs particularly well with raspberry and lemon.
For a richer version, melt about 100–150 g white chocolate, cool it slightly and incorporate it into the cheesecake mixture.
Because this changes the consistency, you may need to adjust the recipe rather than simply adding a large amount.
Can I add a lemon glaze?
Yes.
Mix:
1 cup (120 g) powdered sugar
1–2 tbsp lemon juice
Drizzle very lightly over completely chilled bars.
For the appearance in your photograph, however, I’d skip the glaze — the raspberry marbling looks better without it.
My Recommended Version for the Photo
If your goal is to reproduce the appearance in the uploaded photo, I’d use:
Golden shortbread base + thick lemon cheesecake + lots of raspberry sauce + some whole raspberry pieces + relatively loose knife swirling.
The key visual trick is not to completely blend the raspberry into the cheesecake. Leave distinct dark raspberry clusters and long pink ribbons.
