There’s something deeply nostalgic about the tang of lemon and the lush sweetness of blackberries. For me, Blackberry Lemon Curd Bars represent a perfect fusion of two seasons—spring’s awakening lemons and the late-summer jewels that are blackberries. Every time I make them, I’m taken back to warm days spent picking berries in my aunt’s backyard, filling up old enamel bowls while swatting at mosquitos and sneaking sun-warmed fruit into my mouth when I thought no one was looking.
My aunt was a master of lemon curd, always whisking it gently over the stove until it reached that perfect, glossy texture. But it wasn’t until she folded in a swirl of blackberry that her classic treat became something truly unforgettable. The flavor was rich but fresh, tart but sweet, all layered on a crust that crumbled perfectly with each bite. I remember her cutting perfect squares and serving them on delicate porcelain plates—simple, yet elegant.
Over time, I’ve made this recipe my own, balancing the buttery shortbread crust with a vivid blackberry-lemon curd that sits somewhere between jammy and custardy. It’s a dessert that holds up beautifully for gatherings, celebrations, or just a quiet treat with a cup of tea. When topped with a soft meringue or dusted with powdered sugar, these bars are as stunning as they are delicious.

Ingredients
- For the Buttery Shortbread Crust:
-
1 cup (141 g) all-purpose flour
-
½ cup (100 g) granulated sugar
-
½ tsp kosher salt
-
8 tbsp (114 g) unsalted butter, melted
- For the Blackberry Lemon Curd Filling:
-
2 cups (227 g) fresh blackberries
-
½ cup fresh lemon juice (from about 3–4 lemons)
-
1¼ cups (250 g) granulated sugar
-
2 whole eggs
-
4 egg yolks
-
6 tbsp (84 g) unsalted butter, cut into pieces
- Optional Meringue Topping:
-
3 egg whites
-
¾ cup (150 g) granulated sugar
Instructions
1. Prepare the Shortbread Crust:
Start by preheating your oven to 350°F (177°C). Line an 8×8-inch square pan with foil, allowing a bit of overhang so you can lift the bars out easily later. Lightly grease the foil with butter or cooking spray.
In a medium bowl, combine the flour, sugar, and salt. Pour in the melted butter and stir until the dough comes together—it should feel sandy but hold when pressed. Transfer the mixture into your prepared pan, pressing it evenly across the bottom with your fingers or the flat bottom of a glass.
Bake for 18–22 minutes, or until the crust is lightly golden and set. Set aside while you prepare the curd.
2. Make the Blackberry Puree:
In a food processor or blender, blend the fresh blackberries until smooth. Pour the puree through a fine mesh sieve into a bowl, using a spoon or spatula to press out as much juice as possible. Discard the seeds and pulp. You should end up with about ¾ cup of rich, deep-purple puree.
3. Cook the Blackberry Lemon Curd:
In a medium, heavy-bottomed saucepan, combine the blackberry puree, lemon juice, sugar, whole eggs, and egg yolks. Add the butter and whisk everything over medium-low heat. Keep whisking constantly—this step takes some patience, but it’s worth it. The mixture will begin to thicken after about 8–10 minutes.
For best results, use a thermometer. The curd is ready when it reaches 185–190°F (85–88°C). Immediately pour it through a clean mesh sieve into a bowl to remove any curdled egg or zest pieces. This ensures your final bars have that silky, luxurious finish.
4. Bake the Bars:
Pour the still-warm curd over your baked crust, spreading it evenly. Bake again at 350°F for 13–15 minutes, just until the edges are set and the center jiggles slightly when you gently shake the pan.
Let the bars cool to room temperature, then chill in the refrigerator for at least 2 hours—or overnight for best texture.
5. Optional Meringue Topping:
If you’d like a show-stopping finish, prepare a meringue. Whisk egg whites and sugar together in a heatproof bowl set over a pot of simmering water (a double boiler). Stir constantly until the mixture reaches 160°F, then beat with a mixer until stiff, glossy peaks form.
Pipe or spoon the meringue on top of the chilled bars and gently toast with a kitchen torch for a golden finish.
6. Slice and Serve:
Using the foil overhang, lift the chilled bars from the pan and place on a cutting board. Slice into 16 neat squares. Wipe the knife clean between cuts for tidy edges. Serve immediately or store chilled.
Notes
-
You can make the curd up to one week in advance and store it in the fridge.
-
The bars will firm up more the longer they chill—overnight is ideal for clean cuts.
-
Meringue is optional but highly recommended for special occasions or guests.

HELPFUL TIPS
- Room temperature eggs integrate more smoothly into the curd.
- Use fresh lemons for the brightest flavor—bottled juice just won’t give you the same pop.
- Strain twice if needed for the smoothest curd—especially if your blackberries are extra seedy.
- Chill completely before slicing to avoid a runny mess.
- Torch the meringue right before serving to preserve the texture and height.

FREQUENTLY ASKED QUESTIONS
Can I make these gluten-free?
Yes! Substitute the all-purpose flour in the crust with a 1:1 gluten-free flour blend.
What if I don’t have fresh blackberries?
Frozen blackberries work well—just thaw and drain them first, then puree and strain as usual.
Do I have to use a thermometer for the curd?
It helps! But if you don’t have one, look for the curd to thicken enough to coat the back of a spoon. Run your finger through it—if the line holds, it’s done.
