French Chocolate Flan Ingredients
For the Custard
• Egg Yolks – Provides richness and helps set the custard.
• Whole Eggs – Contributes to structure and stability in the custard.
• White Sugar – Adds sweetness to the custard; can use coconut sugar for a caramel flavor.
• Cornstarch – Acts as a thickening agent for the custard; substitutable with arrowroot.
• Salt – Enhances sweetness and balances flavors.
• Whole Milk – Adds creaminess to the custard; substitute with almond milk for a lighter version.
• Heavy Cream – Provides richness; can be replaced with full-fat coconut milk for a dairy-free option.

Step‑by‑Step Instructions for French Chocolate Flan
Step 1: Prepare Tart Base
In a bowl, whisk together 1 cup of all-purpose flour, 1/4 cup icing sugar, 1/4 cup cocoa powder, and a pinch of salt. Pour in 1/2 cup melted butter and 1 teaspoon vanilla extract, mixing until combined. Press this mixture evenly into the bottom and up the sides of a tart pan. Chill in the refrigerator while you prepare the custard.
Step 2: Make Custard
In a separate bowl, whisk together 4 egg yolks, 2 whole eggs, 1/2 cup sugar, 2 tablespoons cornstarch, and a pinch of salt until smooth. In a saucepan, heat 2 cups of whole milk and 1 cup of heavy cream over medium heat until it just starts to boil. Slowly whisk this hot mixture into the egg mixture to temper the eggs, preventing curdling.
Step 3: Add Chocolate
Melt 7 ounces of dark chocolate in a microwave or a double boiler until smooth. Gradually stir the melted chocolate into the custard mixture, blending until completely combined and glossy. This chocolate concoction will serve as the rich filling for your French Chocolate Flan.
Step 4: Bake
Preheat your oven to 350°F (175°C). Pour the custard mixture into the chilled tart shell, filling it to the top. Bake for 40-50 minutes, or until the edges are set and the center is slightly wobbly. Keep an eye on it; a firm outer edge with a slight jiggle in the middle is the perfect indication it’s ready.
Step 5: Cool and Glaze
Once baked, remove the tart from the oven and allow it to cool at room temperature for about 30 minutes. For a beautiful finish, brush the top of the flan gently with your choice of fruit jam, creating a lovely glaze. Place it in the refrigerator and chill for at least two hours before slicing to set the flavors beautifully.
Step 6: Slice and Serve
When ready to serve, use a sharp knife to slice your French Chocolate Flan into wedges. The silky custard pair with crunchy tart is just dreamy. Consider serving it with fresh berries or a dollop of whipped cream for an added touch of indulgence, transforming this dessert into an irresistible treat.

Make Ahead Options
You can easily prepare the French Chocolate Flan ahead of time, making it a fantastic option for busy home cooks. Start by making the tart base and store it in the refrigerator for up to 3 days, completely covered to maintain its crisp texture. As for the custard, you can whip it up 24 hours in advance; just remember to let it cool completely before filling the tart shell. To keep the custard creamy and flavorful, cover the top with plastic wrap to prevent any unwanted skin from forming. When you’re ready to serve, simply bake the assembled flan as directed, cool it, and glaze with jam for a glossy finish. With these make-ahead strategies, your dessert will be just as delicious while saving you precious time!
Expert Tips for the Best French Chocolate Flan
-
Room Temperature Ingredients: Always use room temperature eggs and milk for a smoother custard. It helps prevent curdling and creates the perfect texture.
-
Slow Whisking: When mixing hot milk into the eggs, whisk slowly to avoid cooking the eggs too quickly. This prevents a grainy texture in your French Chocolate Flan.
-
Chill Before Glazing: Allow the flan to cool completely at room temperature before glazing with jam. This yields a beautiful, even finish and prevents the jam from melting.
-
Check for Doneness: Keep an eye on the baking time. The flan should be set at the edges and slightly jiggly in the center; this ensures a creamy consistency.
-
Flavor Variations: Don’t hesitate to add a splash of espresso or orange zest to the custard for a unique twist. It enhances the chocolate flavor beautifully!
-
Storage Tips: If you have leftovers, store them covered in the refrigerator. Enjoy them within three days for the best flavor and texture.
Storage Tips for French Chocolate Flan
Fridge: Store any leftover French Chocolate Flan tightly covered in the refrigerator for up to 3 days to maintain its creamy texture.
Freezer: For longer storage, you can freeze the flan for up to 1 month. Ensure it’s wrapped tightly in plastic wrap and then sealed in an airtight container.
Thawing: When ready to enjoy, thaw the flan overnight in the refrigerator. Avoid microwaving, as this can alter the delicate texture.
Reheating: If you prefer it warm, gently reheat individual slices in a preheated oven at 300°F (150°C) for about 10 minutes, ensuring not to overheat it.
What to Serve with French Chocolate Flan
There’s nothing quite like creating a delightful spread to accompany the rich flavors of your homemade dessert.

French Chocolate Flan Recipe FAQs
What type of chocolate is best for this French Chocolate Flan?
For the richest flavor, use high-quality dark chocolate with a cacao percentage of 60-70%. If you prefer a sweeter profile, semi-sweet chocolate is also a great choice. I often experiment with different types, and dark chocolate always yields a beautifully intense flavor.
How should I store leftovers of French Chocolate Flan?
Store any leftover French Chocolate Flan tightly covered in the refrigerator for up to 3 days to maintain its creamy texture. If you want to prolong its shelf life, you can freeze it for up to 1 month. Just wrap it tightly in plastic wrap and place it in an airtight container.
Can I make this French Chocolate Flan in advance?
Absolutely! This dessert actually tastes better when made a day ahead, as it allows the flavors to meld beautifully. Just make sure to store it in the refrigerator covered with plastic wrap or foil to keep it fresh.
What if my custard curdles while making the French Chocolate Flan?
If your custard curdles, don’t panic! This can happen if the hot milk is added too quickly. To fix it, pour the mixture into a blender and blend it until smooth. Then, strain it through a fine-mesh sieve to remove any curdled bits before pouring it into the tart shell.
Can I use non-dairy alternatives for the ingredients?
Yes, absolutely! For a dairy-free version, substitute heavy cream with full-fat coconut milk and whole milk with almond milk. This maintains the richness of the dessert while accommodating dietary preferences. Just ensure that all substitutes are unsweetened to avoid altering the flavor.
How can I tell when the French Chocolate Flan is done baking?
To check for doneness, look for a firm outer edge with the center still slightly wobbly when you shake the pan gently. It should take about 40-50 minutes at 350°F (175°C). The flan continues to set while cooling, so you don’t want it to be completely firm in the oven.
