# What You’ll Need:
→ Sweet Tart Crust
01 - 1¼ cups all-purpose flour
02 - ¼ cup powdered sugar
03 - ½ cup unsalted butter, cold and diced
04 - 1 large egg yolk
05 - 1–2 tablespoons cold water
06 - Pinch of salt
→ Chocolate Flan Custard
07 - 2 cups whole milk
08 - 1 cup heavy cream
09 - 4 oz bittersweet chocolate, chopped
10 - ½ cup granulated sugar
11 - 3 large eggs
12 - 2 large egg yolks
13 - 2 tablespoons cornstarch
14 - 1 teaspoon pure vanilla extract
15 - Pinch of salt
# Directions:
01 - Combine flour, powdered sugar, salt, and diced cold butter in a bowl. Rub together with your fingers or pulse in a food processor until the mixture resembles coarse sand. Add the egg yolk and just enough cold water to bring the dough together. Flatten into a disc, wrap tightly in plastic, and refrigerate for 30 minutes.
02 - Preheat oven to 350°F. Roll out the chilled dough on a lightly floured surface and carefully press it into a 9-inch tart pan. Prick the base several times with a fork. Line with parchment paper and fill with baking beans. Bake for 12 minutes, then remove the beans and parchment. Continue baking for 5–7 minutes until the crust is lightly golden. Set aside to cool slightly.
03 - In a medium saucepan, gently heat the whole milk and heavy cream until steaming but not boiling. Remove from heat and stir in the chopped bittersweet chocolate, whisking until fully melted and smooth.
04 - In a large bowl, whisk together the granulated sugar, whole eggs, egg yolks, cornstarch, vanilla extract, and salt until completely smooth. Gradually pour the warm chocolate mixture into the egg mixture, whisking constantly to temper the eggs without scrambling them.
05 - Pass the custard through a fine-mesh sieve to remove any lumps, then pour the smooth filling into the pre-baked tart shell. Gently tap the pan on the counter to release any trapped air bubbles.
06 - Bake at 350°F for 30–35 minutes, until the edges are set but the center still has a gentle wobble when nudged. Avoid overbaking, as the custard will continue to set as it cools.
07 - Allow the tart to cool completely to room temperature, then refrigerate for at least 3 hours before slicing. Serve chilled, optionally dusted with cocoa powder or accompanied by fresh berries.
# Expert Suggestions:
01 -
- The custard sets into something so smooth it barely holds together, which is exactly how it should be and your guests will notice.
- You can make the entire thing a day ahead and it actually tastes better after a night in the fridge, making it a stress free dinner party dessert.
- Using bittersweet chocolate instead of semisweet gives you a grown up flavor that is not too sweet and pairs beautifully with coffee or dessert wine.
02 -
- Pouring the hot chocolate mixture all at once into the eggs will give you scrambled chocolate custard, so add it slowly and whisk without stopping.
- The center of the flan should still wobble slightly when you take it out of the oven and if you bake it until fully firm it will be rubbery once chilled.
- Straining the custard feels like an extra step but it is the single thing that separates a lumpy home version from something that tastes like it came from a French bakery.
03 -
- Let the tart crust cool completely before pouring in the custard because a warm crust will start cooking the filling at the edges before the center has a chance to set evenly.
- Cover the surface of the dough with plastic wrap directly against the pastry while it chills to prevent it from drying out and cracking when you roll it.
