-
Whole Milk (2 ½ cups / 600ml) – Provides creaminess; you can replace with almond or oat milk for a dairy-free version.

Step‑by‑Step Instructions for French Chocolate Flan
Step 1: Prepare the Tart Base
In a mixing bowl, combine 1 cup of all-purpose flour, ⅓ cup of icing sugar, ¼ cup of cocoa powder, and ¼ teaspoon of salt. Mix these dry ingredients until well blended. Then, add 1 stick of melted butter and ½ teaspoon of vanilla extract; use your hands to blend until the mixture becomes crumbly. Press this dough into a tart pan, ensuring an even layer, and pre-bake in a preheated oven at 350°F (175°C) for about 10 minutes, or until slightly firm.
Step 2: Make the Chocolate Custard
While the tart base is baking, whisk together 3 egg yolks and 2 whole eggs in a mixing bowl. Gradually add 1 cup of white sugar, ⅓ cup of cornstarch, and ½ teaspoon of salt, mixing until smooth. Slowly stir in 2 ½ cups of whole milk and 1 ¾ cups of heavy cream, ensuring everything is well combined. Afterwards, melt 7 ounces of dark chocolate, then gently fold it into the custard mixture until fully incorporated and silky.
Step 3: Bake the Flan
Once the tart base is ready, remove it from the oven and pour the chocolate custard mixture into it. Set the tart pan into a larger baking dish and fill the larger dish with hot water, creating a water bath. Bake the French chocolate flan at 325°F (163°C) for about 50-60 minutes, or until the custard is just set but still slightly jiggly in the center. Check for doneness by gently shaking the pan; the edges should be firm while the middle remains soft.
Step 4: Cool and Serve
After baking, carefully remove the tart pan from the water bath and let the flan cool at room temperature for about 30 minutes. Once cooled, refrigerate for at least 2 hours, allowing the flavors to meld and the texture to set. Before serving, give the top a glossy finish by brushing it with 1 tablespoon of jam, and enjoy a slice of your beautifully made French chocolate flan with friends and family!

French Chocolate Flan Recipe FAQs
What type of chocolate should I use for the flan?
Absolutely! I recommend using high-quality dark chocolate (around 70% cocoa) for a rich flavor. If you prefer a less sweet option, you can opt for unsweetened chocolate. Its depth will truly elevate your flan!
How can I tell when the flan is done baking?
Very important! The flan should be slightly jiggly in the center when it’s done, but it shouldn’t look liquidy. A gentle shake of the pan should show firm edges while the middle retains a soft wobble. This is the hallmark of a perfectly cooked custard!
How should I store leftovers of the French chocolate flan?
To keep your delicious flan fresh, store it in the refrigerator, covered, for up to 3 days. This allows the flavors to deepen beautifully over time. Always make sure it’s airtight to prevent it from absorbing any unwanted odors from your fridge.
Can I freeze the French chocolate flan?
Absolutely! You can freeze individual slices of the flan for up to 2 months. Wrap each slice tightly in plastic wrap, followed by aluminum foil to protect it from freezer burn. When you’re ready to enjoy, simply thaw in the refrigerator for a few hours before serving.
What should I do if my custard breaks or curdles?
No worries! If your custard looks curdled, it might be a sign of overheating or using cold ingredients. To remedy this, ensure all ingredients are at room temperature before mixing. Also, try to bake in a water bath; this gentle cooking method helps prevent curdling. If you notice curdling, you can blend it briefly to smooth it out before pouring it into the tart shell, but be careful not to overdo it!
Is there a way to make this recipe dairy-free?
Yes, indeed! You can substitute the whole milk and heavy cream with plant-based alternatives like almond milk or coconut cream. Ensure that the dark chocolate you choose is dairy-free as well. This way, you can still enjoy a luscious flan without the dairy!
