Ingredients
For the shortbread base (cookie crust):
- 300g plain flour (all-purpose flour)
- 75g icing sugar (powdered sugar)
- ½ tsp salt
- 175g unsalted butter, melted
For the lemon filling
- 70g plain flour (all-purpose flour)
- Zest of 3 lemons
- 600g caster sugar (superfine sugar)
- 8 large eggs, at room temperature
- 240g fresh lemon juice
For the brûlée topping:
- Granulated sugar, for caramelizing
Equipment:
- 23 x 33cm (9 x 13 inch) baking tin
- Baking paper
- Blow torch
Method

Step 1
Prepare the shortbread base:
- Preheat your oven to 175°C (350°F).
- Line a 23 x 33cm (9 x 13 inch) baking tin with baking paper.
- In a large bowl, whisk together the flour, icing sugar and salt.
- Pour in the melted butter and mix until just combined.
- Press the dough evenly into the lined tin and bake for 20 minutes, or until lightly golden.
Step 2
Make the lemon filling:
- While the base is baking, rub the lemon zest into the caster sugar to release the citrus oils.
- In a separate bowl, mix together the zested sugar and 70g flour.
- Add the lemon juice and eggs, whisking until fully combined and smooth.
Step 3
Bake the bars:
- Pour the lemon filling onto the hot shortbread base, straight out of the oven.
- Immediately return to the oven and bake for 25 minutes, turning the tin halfway through for even baking.
- Remove from the oven and allow to cool at room temperature for 1 hour, then chill in the fridge until fully set.
- Take out of the tin and baking paper, and cut into bars the desired size.
Step 4
Brûlée the top:
- Once cut, evenly sprinkle a thin layer of granulated sugar over the bars.
- Use a blow torch to caramelise the sugar until golden and crisp.
- Alternatively you can use your oven grill: place the bars on a baking sheet without the baking paper underneath, and place under the grill. Keep a very close eye as the sugar will caramelise quickly. (It’s better to do it multiple times for a shorter time than once for too long as the bars will be ruined)
- For an extra hard crack, repeat the brûlée process with another layer of sugar.
- Let the sugar set for a few minutes before serving.
Top tips for perfect Brûlée Bars
✔ Pour the lemon mix onto the hot shortbread, straight out of the oven, then return it to bake. This helps the layers bind perfectly.
✔ Use a damp knife to cut the bars cleanly, re-damping the knife between each slice to prevent sticking.
✔ For a thicker, crunchier brûlée layer, do several layers of caramelised sugar—torch one layer, let it set, then add another.
Enjoy your Lemon Brûlée Bars—crispy, creamy, and delicious!
