Ingredients
For the Chocolate Custard:
- 3 egg yolks
- 2 whole eggs
- 1 cup (200g) white sugar
- ⅓ cup (42g) cornstarch
- ½ teaspoon salt
- 2 ½ cups (600ml) whole milk
- 1 ¾ cups (400ml) heavy cream
- 7 oz (200g) dark chocolate, chopped
- 1 tablespoon jam (for brushing on top)
For the Chocolate Tart Base:
- 1 cup (120g) all-purpose flour
- ⅓ cup (35g) icing sugar
- ¼ cup (25g) cocoa powder
- ¼ teaspoon salt
- 1 stick (114g) butter, melted
- ½ teaspoon vanilla extract
Instructions
- Make the Chocolate Tart Base:
- In a bowl, combine the flour, icing sugar, cocoa powder, and salt.
- Preheat the oven to 350°F (180°C) and line a baking sheet with parchment paper.
- Melt the butter in the microwave and add it to the dry ingredients along with the vanilla extract.
- Mix until a smooth, thick paste forms.
- Knead the mixture into a dough for 3-4 turns. Be careful not to overwork it.
- Flatten the dough into a large circle, slightly bigger than your pastry ring. You can use your hands or a small rolling pin. The edges don’t need to be perfect as they will be trimmed.
- Bake for 10 minutes, or until the top looks dry.
- Immediately press the pastry ring into the baked pastry like a large cookie cutter. Do not remove the pastry ring.
- If using a loose-bottomed cake pan instead of a pastry ring, refer to the notes for adjustments.
- Make the Chocolate Custard:
- Whisk the egg yolks, whole eggs, and sugar together in a bowl for about 30 seconds until the mixture lightens slightly.
- Add the cornstarch and salt, whisking until smooth.
- Heat the milk and cream in a large saucepan over medium heat. Once steam begins to rise, slowly add a small amount of the hot milk mixture to the egg mixture, whisking constantly. Gradually add more milk, a little at a time, while continuing to whisk to avoid cooking the eggs.
- Once all the milk has been incorporated, return the mixture to the saucepan and reduce the heat to medium-low. Whisk continuously until the custard starts to bubble, then cook for another 1-2 minutes until it thickens.
- The custard is done when it coats the back of a spoon and a line remains when you run your finger through it.
- Remove from heat and, if necessary, strain the custard through a sieve to remove any lumps.
- Add the chopped dark chocolate to the custard and whisk until fully melted and smooth.
- Assemble the Chocolate Flan:
- The pastry ring should still be sitting on the cooled pastry. Trim away any excess pastry from the sides.
- Lightly grease the inside of the pastry ring with butter.
- Pour the chocolate custard into the ring, smoothing the top with a palette knife.
- Bake for 50-60 minutes. The flan should be set around the edges but still jiggly in the center.
- Let the flan cool to room temperature, then cover with plastic wrap and refrigerate overnight.
- Finishing Touches:
- Once chilled, carefully remove the flan from the pastry ring. If it doesn’t release easily, use a sharp knife around the edges or apply some heat to the outside.
- For a glossy finish, melt 1 tablespoon of jam in the microwave for 20 seconds, then brush a thin layer over the top of the flan. Apricot jam is traditional, but strawberry jam works well too.
Tips
- Ensure that the milk mixture is hot enough before adding it to the egg mixture to prevent curdling.
- If the flan cracks during baking, reduce the oven temperature slightly next time.
- Be careful not to overbake the custard; it should still have a slight jiggle in the center when you take it out.

Variations and Substitutions
- Flavored Jam: Use different types of jam, such as raspberry or apricot, for a unique finish.
- Vegan Option: Use non-dairy milk (like coconut milk) and a dairy-free butter substitute for the tart base and custard.
- Spiced Chocolate Flan: Add a pinch of cinnamon or chili powder to the custard for a spicy twist.
FAQs
- Can I make this ahead of time?
Yes, the flan can be made up to 2 days ahead. Just be sure to let it chill completely in the fridge. - Why is my custard not thickening?
If your custard isn’t thickening, it may need more cooking. Keep whisking on medium-low heat until it reaches the desired consistency. - Can I use a different type of chocolate?
You can substitute milk chocolate or white chocolate, but the texture and flavor of the flan will change. Dark chocolate gives the custard a rich, intense flavor.
Serving Suggestions
- Serve the chocolate flan with a dollop of whipped cream or fresh berries for added texture and flavor.
- A light dusting of cocoa powder or grated chocolate on top can enhance the presentation.
- Pair it with a cup of coffee or a glass of dessert wine for a sophisticated dessert experience.
