Ingredients
Here’s everything you’ll need to make this delightful dessert. Make sure to measure accurately to get the perfect results!
Blueberry Sauce:
- 1 teaspoon cornstarch – Helps thicken the sauce and create that perfect texture.
- 2 teaspoons lemon juice (or water) – Adds a hint of citrus to balance the sweetness.
- 1 cup (140g) fresh or frozen blueberries – The star of the show! Fresh blueberries will offer a vibrant color, but frozen blueberries work perfectly as well.
- 2 teaspoons granulated sugar – Just enough sweetness to bring out the blueberry flavor.
Shortbread Crust:
- 1/2 cup (8 Tbsp; 113g) unsalted butter, melted – Butter is essential for that rich, crumbly texture in the crust.
- 1/4 cup (50g) granulated sugar – Adds sweetness to the crust.
- 1 teaspoon pure vanilla extract – For a touch of vanilla flavor.
- 1/4 teaspoon salt – Enhances the sweetness of the crust and balances the flavors.
- 1 cup (125g) all-purpose flour (spooned & leveled) – The base of the crust. Spoon the flour into the measuring cup and level off for accuracy.
Lemon Filling:
- 1 (14 ounce weight) can full-fat sweetened condensed milk – This makes the filling creamy and rich.
- 6 Tablespoons (90ml) lemon juice (about 2 lemons) – Fresh lemon juice is key for that bright, tangy flavor.
- 1 teaspoon lemon zest (1 lemon) – The zest adds a lovely citrus fragrance to the filling.
- 1 large egg yolk – The yolk helps thicken the filling and adds a silky texture.
Optional Garnishes:
- Lemon slices – For a fresh, decorative touch.
- Blueberries – A handful of fresh blueberries will add pops of color on top.
- Leftover blueberry sauce – Drizzle it over the tarts for an extra burst of flavor.
- Whipped cream – A dollop of freshly whipped cream can elevate the presentation.

Step-by-Step Instructions
1. Prepare the Shortbread Crust
The shortbread crust is the foundation of this tart. It’s buttery, crumbly, and the perfect complement to the tart lemon filling.
How to Make It:
- Preheat your oven to 350°F (177°C).
- Mix the crust ingredients: In a medium bowl, combine the melted butter, sugar, vanilla extract, and salt. Stir until well combined.
- Add the flour: Slowly add the flour to the butter mixture. Use a pastry cutter, fork, or your fingers to incorporate the flour into the butter until the dough resembles coarse crumbs.
- Form the crust: Press the dough into the bottom and up the sides of your tart pans. If you’re using individual tart pans, be sure to press firmly so that the dough is evenly spread.
- Chill the crust: Place the tart pans in the fridge for 10-15 minutes. This will help the crust hold its shape during baking.
- Bake: Bake the crust in the preheated oven for about 12-15 minutes or until golden brown. Remove from the oven and let it cool completely.
2. Make the Blueberry Sauce
The blueberry sauce is a sweet and tangy topping that ties everything together. It’s quick to make and really elevates the flavor of the tarts.
How to Make It:
- Cook the blueberries: In a small saucepan, combine the blueberries, sugar, and lemon juice (or water). Stir to coat the blueberries evenly.
- Thicken the sauce: In a small bowl, whisk the cornstarch with a little bit of water (about 1 tablespoon) until smooth. Add this mixture to the blueberries in the saucepan.
- Simmer: Bring the mixture to a simmer over medium heat. Stir frequently and cook for 5-7 minutes, or until the sauce thickens and the blueberries start to break down. Remove from heat and let it cool completely.
3. Prepare the Lemon Filling
The lemon filling is smooth, creamy, and full of zesty citrus flavor. It’s what truly makes these tarts irresistible!
How to Make It:
- Whisk together the condensed milk and lemon juice: In a medium mixing bowl, combine the sweetened condensed milk and lemon juice. Stir until fully incorporated.
- Add the egg yolk and zest: Add the egg yolk and lemon zest to the mixture and whisk until smooth. The egg yolk helps thicken the filling and adds richness.
- Set aside: Once the filling is mixed, set it aside while you work with the crust and the blueberry sauce.
4. Assemble the Tarts
Once the shortbread crust is baked and cooled, it’s time to fill the tart shells with that luscious lemon filling and top them with blueberry sauce.
How to Assemble:
- Fill the crusts: Spoon the lemon filling into each tart shell, filling them almost to the top.
- Top with blueberry sauce: Add a spoonful of the cooled blueberry sauce on top of the lemon filling. You can swirl it lightly for a marble effect or leave it in dollops for more of a visual contrast.
- Chill the tarts: Place the assembled tarts in the refrigerator for at least 1-2 hours, or until the filling sets.
5. Garnish and Serve
Once the tarts have chilled and set, they’re ready to be garnished and served.
How to Garnish:
- Decorate with lemon slices: Place thin slices of lemon on top of the tarts for an extra burst of citrus.
- Add fresh blueberries: Scatter a few fresh blueberries on top for an added touch of freshness and color.
- Drizzle leftover blueberry sauce: If you have any leftover blueberry sauce, drizzle it over the tarts for an extra hit of flavor.
- Top with whipped cream: For an indulgent touch, add a dollop of freshly whipped cream on top.
