Ingredients You’ll Need
This Mixed Berry Tart with Custard Filling Recipe comes together beautifully with simple, every-day ingredients that each play a starring role — from the flaky crust to the silky custard and the jewel-like berries on top. Having them ready and understanding their part will make the baking process that much more enjoyable.
- All-purpose flour: Provides the structure and tenderness of the tart crust.
- Powdered sugar: Adds subtle sweetness and a delicate texture to the crust.
- Salt: Enhances all the flavors, making the crust perfectly balanced.
- Unsalted butter (cold and cubed): Creates a flaky, rich crust when cut into the flour mixture.
- Cold water: Helps bring the dough together without warming the butter.
- Whole milk: The rich base for the creamy custard filling.
- Granulated sugar: Sweetens the custard without overpowering it.
- Cornstarch: Thickens the custard to that perfect spoonable consistency.
- Large egg yolks: Give the custard its smooth texture and golden color.
- Vanilla extract: Adds comforting aroma and depth to the custard.
- Unsalted butter: Stirred into the custard for extra richness and silkiness.
- Mixed fresh berries: A colorful blend of strawberries, blueberries, raspberries, and blackberries tops the tart with sweet and tart flavors.
- Apricot jam (optional): Warmed and brushed over the berries to give a shiny, professional-looking glaze.
How to Make Mixed Berry Tart with Custard Filling Recipe
Step 1: Prepare the Tart Crust
Start by preheating your oven to 375°F (190°C). In a food processor or mixing bowl, combine the flour, powdered sugar, and salt — these dry ingredients form the base of a tender yet sturdy crust. Next, add cold, cubed butter and pulse or cut it into the flour until you get coarse crumbs. This step is what creates the flakiness we all love. Slowly add cold water one tablespoon at a time until the dough forms. Press this dough evenly into a 9-inch tart pan, prick the bottom with a fork to prevent puffing, and bake for 15 to 18 minutes until it’s a lovely light golden brown. Once baked, let it cool completely. This crust will set the stage for the luscious filling and fresh fruit topping.
Step 2: Make the Custard Filling
While the crust cools, it’s time for the custard magic. Heat the milk over medium heat until it’s just steaming — not boiling. Meanwhile, whisk together the sugar, cornstarch, and egg yolks in a separate bowl until smooth and slightly pale. This careful whisking will prevent lumps and give you that silky finish. Slowly pour the hot milk into the egg mixture, whisking constantly, then return everything to the saucepan. Cook over medium heat, stirring frequently, until thickened (about 4 to 6 minutes). Once thick, remove from heat and stir in vanilla extract and butter for that luscious, velvety texture. Transfer to a bowl, press plastic wrap directly on the surface to avoid skin forming, and chill until completely cool.
Step 3: Assemble the Tart
Once the crust and custard are fully cooled, spread the custard evenly inside the shell. Then, gently arrange the fresh mixed berries on top — this is where your tart becomes a vibrant work of art. If you want an extra glossy finish that also helps seal in freshness, warm the apricot jam and brush it lightly over the berries. This step is optional but highly recommended for that wow factor. Finally, refrigerate the tart for at least one hour before serving to let everything set beautifully.
How to Serve Mixed Berry Tart with Custard Filling Recipe

Garnishes
To elevate your Mixed Berry Tart with Custard Filling Recipe, sprinkle a little powdered sugar just before serving for a delicate snow-kissed look. Fresh mint leaves or edible flowers add a refreshing aroma and a pop of color that will impress your guests and make the dessert feel extra festive.
Side Dishes
This tart shines wonderfully on its own, but pairing it with a dollop of freshly whipped cream or a scoop of vanilla bean ice cream takes it to indulgent new heights. A light green salad with a citrus vinaigrette can provide a refreshing counterbalance to this rich dessert if you plan to serve it as the grand finale of a meal.
Creative Ways to Present
For a fun twist, create individual mini tarts using smaller tart pans and arrange them on a serving platter for a party-friendly dessert. You can also drizzle a bit of dark chocolate around the plate or add a berry coulis for a restaurant-style presentation that will wow the senses before the first bite.
Make Ahead and Storage
Storing Leftovers
If by any chance you have leftovers, cover your tart tightly and keep it refrigerated for up to three days. The custard and berries stay fresh, and the crust retains a good amount of its crispness if stored properly. Eating it within this time frame guarantees the best flavor and texture.
Freezing
This Mixed Berry Tart with Custard Filling Recipe is best enjoyed fresh, but if you want to freeze, only freeze the tart shell or the custard separately before assembly. The berries do not freeze well and can become mushy. When ready to serve, thaw and assemble the tart fresh to preserve the delightful contrast between creamy custard and fresh fruit.
Reheating
Because this tart is best served chilled, reheating is not recommended. If you want to warm the crust a bit, you can carefully heat the crust alone in an oven at low temperature before adding the chilled custard and berries. This trick can revive some crispness if the crust has softened after refrigeration.
FAQs
Can I use frozen berries for this tart?
While fresh berries are ideal for their texture and flavor, you can use frozen berries if fresh aren’t available. Just make sure to thaw and drain them well to avoid a soggy tart.
How long does the custard need to chill?
Chilling the custard for at least an hour is best to ensure it sets properly and is cool enough to spread without melting the crust or berries atop.
Can I make the tart crust ahead of time?
Absolutely! The crust can be made and baked the day before, then stored covered at room temperature or lightly wrapped in the fridge. This makes assembly on the day of serving quick and easy.
What if my custard is too runny?
If your custard doesn’t thicken enough, next time try adding an extra teaspoon of cornstarch. Cooking it a bit longer while stirring should also help it thicken without curdling.
Is this recipe suitable for vegetarians?
Yes, the Mixed Berry Tart with Custard Filling Recipe is vegetarian-friendly but not vegan due to the eggs, milk, and butter involved.
Final Thoughts
I can’t recommend this Mixed Berry Tart with Custard Filling Recipe enough — it’s a dessert that brings warmth and joy to any table. Its simple ingredients come together to create a show-stopping dessert that’s both elegant and approachable.

Description
A delightful French-inspired mixed berry tart featuring a buttery, flaky crust filled with smooth vanilla custard and topped with a vibrant mix of fresh berries. This summer dessert balances sweet and tangy flavors with a luscious texture, perfect for any occasion.
Ingredients
For the crust:
- 1 1/4 cups all-purpose flour
- 1/4 cup powdered sugar
- 1/2 teaspoon salt
- 1/2 cup unsalted butter (cold and cubed)
- 1–2 tablespoons cold water
For the custard filling:
- 2 cups whole milk
- 1/2 cup granulated sugar
- 1/4 cup cornstarch
- 4 large egg yolks
- 1 teaspoon vanilla extract
- 1 tablespoon unsalted butter
For the topping:
- 1 1/2 cups mixed fresh berries (such as strawberries, blueberries, raspberries, and blackberries)
- 1 tablespoon apricot jam (optional, for glaze)
Instructions
- Prepare the crust: Preheat the oven to 375°F (190°C). In a food processor or mixing bowl, combine the flour, powdered sugar, and salt. Add cold cubed butter and pulse or cut in until the mixture resembles coarse crumbs. Gradually add cold water, one tablespoon at a time, until the dough comes together. Press the dough evenly into a 9-inch tart pan and prick the bottom with a fork to prevent bubbling. Bake for 15 to 18 minutes until lightly golden, then let cool completely.
- Make the custard filling: Heat the milk in a saucepan over medium heat until just steaming. In a separate bowl, whisk together sugar, cornstarch, and egg yolks until smooth. Slowly pour the hot milk into the egg mixture while whisking constantly to temper the yolks. Return the combined mixture to the saucepan and cook over medium heat, stirring constantly, until thickened to a custard consistency (about 4–6 minutes). Remove from heat, stir in vanilla extract and butter until smooth. Transfer to a bowl, cover with plastic wrap directly on the surface to avoid skin formation, and chill until cool.
- Assemble the tart: Once both the tart shell and custard are completely cooled, spread the custard evenly into the shell. Arrange the mixed fresh berries on top of the custard. If using apricot jam, warm it slightly and brush over the berries to create a glaze for shine and added sweetness.
- Final chill: Refrigerate the assembled tart for at least 1 hour before serving to allow the flavors to meld and the custard to set firmly.
Notes
- For convenience, make the crust and custard a day ahead to simplify assembly on serving day.
- Store-bought tart shells or prepared custard can be used as quicker substitutes if pressed for time.
- To achieve a firmer custard, increase cornstarch by an additional teaspoon during preparation.
