This fruit tart filling is a silky, vanilla-scented pastry cream (crème pâtissière) that holds its shape under a crown of fresh fruit. It comes together in about 15 minutes on the stove, then chills until set, giving you a stable, sliceable base for any tart shell. The recipe balances richness with just enough sweetness to let the fruit shine, and it works with everything from strawberries to kiwi to peaches.
Ingredients
- 2 cups (480 ml) whole milk
- 1/2 cup (100 g) granulated sugar, divided
- 1/4 cup (30 g) cornstarch
- 4 large egg yolks
- 2 tablespoons (30 g) unsalted butter, cut into small pieces
- 1 1/2 teaspoons vanilla extract
- 1/8 teaspoon salt
Instructions
- In a medium saucepan, heat the milk and half of the sugar (1/4 cup / 50 g) over medium heat, stirring occasionally, until steaming and small bubbles form around the edges. Do not let it boil.
- Meanwhile, in a medium bowl, whisk the remaining 1/4 cup (50 g) sugar with the cornstarch, egg yolks, and salt until pale and thick, about 1 minute.
- Slowly pour about 1/2 cup of the hot milk into the yolk mixture, whisking constantly to temper the eggs. Then pour the yolk mixture back into the saucepan with the remaining milk.
- Return the saucepan to medium heat and cook, whisking constantly, until the mixture thickens and comes to a gentle boil. Once it bubbles, cook for 1 full minute, still whisking, to eliminate any raw cornstarch taste. The mixture will be very thick.
- Remove from heat and immediately whisk in the butter, vanilla, and salt until smooth.
- Pour the pastry cream through a fine-mesh strainer into a clean bowl to remove any lumps. Press a piece of plastic wrap directly onto the surface to prevent a skin from forming.
- Refrigerate for at least 2 hours, or until fully chilled and set. The cream will thicken further as it cools.
- Whisk the chilled pastry cream briefly before spreading into a pre-baked tart shell. Fill the tart and top with fresh fruit.
Tips
- Substitutions: For a lighter filling, replace up to half the whole milk with half-and-half or coconut milk (not coconut beverage). For a dairy-free version, use a high-quality plant-based milk (like oat or soy) and vegan butter; the texture will be slightly softer.
- Storage: Pastry cream keeps in the refrigerator for up to 3 days. If it gets too thick after chilling, whisk in a tablespoon of milk to loosen it.
- Common mistake: Not cooking the cream long enough. If you stop as soon as it thickens, the cornstarch won’t be fully activated and the filling will be runny. Always let it boil for 1 minute.
- Lumps: If lumps form, don’t panic. Strain the hot cream through a fine sieve and it will be silky smooth.
Serving Suggestions
Spread the chilled pastry cream into a fully baked 9-inch tart shell and top with a colorful arrangement of fresh berries, sliced kiwi, mango, or stone fruits. Brush the fruit with a light apricot glaze (warm apricot jam with a splash of water) for shine. Serve within 2–3 hours of assembling for the crispest crust.
Variations
- Lemon pastry cream: Add 1 tablespoon of lemon zest with the milk and replace the vanilla with 1 teaspoon of lemon extract.
- Chocolate pastry cream: Whisk 2 ounces (55 g) of melted dark chocolate into the hot cream after straining.
- Coconut: Replace the milk with coconut milk and add 1/2 cup (40 g) of unsweetened shredded coconut with the milk.
- Lighter option: Fold in 1/2 cup (120 ml) of softly whipped heavy cream after the pastry cream has chilled, for a mousse-like texture.
Storage and Reheating
Unfilled pastry cream can be stored in the refrigerator for up to 3 days, with plastic wrap pressed on the surface. Do not freeze, as it will separate upon thawing. Once the tart is assembled, it is best eaten the same day; leftovers can be refrigerated for up to 1 day, but the crust may soften. To reheat, warm the pastry cream gently in a saucepan over low heat, stirring constantly, until just warm (do not boil). Use leftover filling within 2 days.
Frequently Asked Questions
Can I use this filling for a no-bake tart?
Yes, but you must fully chill the pastry cream first, and the crust should be a pre-baked or no-bake cookie crumb crust. The filling is cooked, so it is safe, but it needs to set in the fridge for at least 2 hours.
Why is my pastry cream runny?
Most likely the cornstarch wasn’t cooked long enough. Make sure the mixture reaches a boil and cooks for 1 full minute. Also, ensure you measured the cornstarch correctly – too little will result in a thin filling.
Can I make this ahead of time?
Absolutely. Prepare the pastry cream up to 3 days in advance, keep it chilled, and whisk before using. Assemble the tart no more than a few hours before serving to keep the crust crisp.
Can I use this filling for cream puffs or éclairs?
Yes, this is a classic crème pâtissière that pipes beautifully. Use it as a filling for choux pastry, and it will hold its shape.
What if I don’t have cornstarch?
You can substitute with 1/2 cup (60 g) of all-purpose flour, but the texture will be slightly more gelatinous and less silky. Cook for 2 minutes after boiling to eliminate the raw flour taste.
Can I skip the butter?
Yes, the butter adds richness and shine, but you can omit it for a leaner filling. The texture will be slightly less creamy, but it will still set.
