These gluten-free blueberry cheesecake bars are the perfect balance of textures and flavours: a crisp, buttery lemon shortbread base, a smooth and creamy vanilla cheesecake layer, and bursts of sweet, juicy blueberries in every bite. Finished with a golden shortbread crumble on top, they’re somewhere between a classic cheesecake and a fruit crumble — and honestly, the best of both worlds.
They’re surprisingly easy to make and, most importantly, you’d never guess they’re gluten free. The secret lies in two key steps: using fresh blueberries and pre-baking the shortbread crust. Together, they guarantee a firm, crisp base and a cheesecake layer that sets beautifully without becoming soggy.
These bars do require a little patience at the end, as they need to cool completely and chill before slicing — but the wait is more than worth it. Once chilled, the flavours deepen, the layers firm up, and you’re rewarded with neat, bakery-style slices that taste even better the next day.

Key Tips for Success
- Use fresh blueberries, not frozen. Frozen berries release too much liquid during baking and can make the bars overly soft.
- Bake the shortbread base first. This step is essential for a crisp bottom layer.
- Skip raising agents. Baking powder or baking soda would make the shortbread too fragile.
- Weigh your ingredients if possible. Gluten-free flours vary greatly in density, and accuracy makes a big difference here.
- Chill before slicing. At least 2 hours in the fridge is essential; overnight is even better.

- 65 g almond flour (or finely ground almonds/almond meal)
- ½ teaspoon xanthan gum
(omit if your flour blend already contains it) - ¼ teaspoon salt

- 450 g full-fat cream cheese, room temperature

How to Make Gluten-Free Blueberry Cheesecake Bars
1. Prepare the Pan
Preheat the oven to 180°C (350°F) and position a rack in the centre. Line a 9-inch (23 cm) square baking pan with parchment paper, leaving some overhang to make removal easier later.

2. Infuse the Sugar
Place the sugar and lemon zest into a large bowl. Rub them together with your fingertips until fragrant — this releases the lemon oils and adds extra flavour to the shortbread.
3. Mix the Butter
Add the softened butter and vanilla. Mix until combined, but do not cream or whip — keeping the mixture dense ensures a sturdy shortbread.
4. Add the Dry Ingredients
In a separate bowl, whisk together the gluten-free flour, almond flour, xanthan gum, and salt. Add to the butter mixture and stir until clumps form. Knead briefly until you have a uniform dough.
5. Bake the Base
Press about two-thirds of the dough evenly into the prepared pan. Bake for 20 minutes, or until lightly golden. Remove from the oven and allow it to cool slightly while you prepare the filling. Keep the oven on.

6. Mix the Base
In a large bowl, gently mix the cream cheese and yoghurt until smooth. Avoid whipping air into the mixture — a spatula or paddle attachment on low speed works best.
7. Add Sugar and Eggs
Stir together the sugar and cornflour, then mix into the cream cheese mixture. Add the eggs and vanilla and mix just until smooth.

8. Layer the Bars
Pour the cheesecake filling over the warm shortbread base and smooth it evenly. Scatter the fresh blueberries across the top. Crumble the remaining shortbread dough over the blueberries, leaving some fruit visible.
9. Final Bake
Bake for 40–45 minutes, until the topping is golden and the cheesecake layer is just slightly wobbly in the centre. It should not jiggle excessively.
Cooling and Chilling
Allow the bars to cool completely in the pan at room temperature. Once cool, transfer to the fridge and chill for at least 2 hours, or preferably overnight. This step is crucial for clean slicing and best flavour.
Lift the bars out using the parchment paper, slice into squares, and serve. Dust with icing sugar if desired.
Storage
- Store in an airtight container in the fridge for 3–4 days
- These bars actually improve after a day as the flavours settle
- Best served chilled
