French Chocolate Flan Ingredients
For the Custard
• Egg Yolks (3) – Adds richness and structure to the custard; you can substitute with whole eggs, but yolks yield a creamier texture.
• Whole Eggs (2) – Contributes to the custard’s firmness and texture; none needed as substitutions are part of the recipe’s foundation.
• White Sugar (1 cup / 200g) – Sweetens the custard, balancing the chocolate’s bitterness; try using brown sugar for a caramel-like flavor.
• Cornstarch (⅓ cup / 42g) – Acts as a thickening agent for the custard; arrowroot powder can be a gluten-free alternative.
• Salt (½ teaspoon) – Enhances sweetness and flavor of the chocolate; sea salt works well for a gourmet touch.
• Whole Milk (2 ½ cups / 600ml) – Provides a creamy base for the custard; almond milk can be used for a dairy-free version.
• Heavy Cream (1 ¾ cups / 400ml) – Adds richness and smoothness to the custard; substitute with coconut cream for a dairy-free option.
• Dark Chocolate (7 oz / 200g) – The star ingredient for deep chocolate flavor; semi-sweet chocolate can be used, but it may change the sweetness.
• Jam (1 tablespoon) – Used for brushing on top for a glossy finish; chocolate or apricot jam can work for a different flavor.
For the Tart Base
• All-Purpose Flour (1 cup / 120g) – Essential for the structure of the tart base; gluten-free flour blend can substitute for a gluten-free tart.
• Icing Sugar (⅓ cup / 35g) – Adds sweetness and enhances texture of the tart base; powdered sugar can be used in its place.
• Cocoa Powder (¼ cup / 25g) – Infuses chocolate flavor into the tart base; dark cocoa powder gives a richer taste.
• Butter (1 stick / 114g, melted) – Binds the crust ingredients together, adding richness; coconut oil can be a dairy-free alternative.
• Vanilla Extract (½ teaspoon) – Enhances and deepens the flavor profile; for a more intense flavor, use vanilla bean paste.
Indulge your taste buds with this delightful French chocolate flan, where creamy custard meets a crisp tart base.
Step‑by‑Step Instructions for French Chocolate Flan
Step 1: Prepare the Tart Base
In a large mixing bowl, combine 1 cup of all-purpose flour, ⅓ cup of icing sugar, ¼ cup of cocoa powder, and a pinch of salt. Pour in 1 stick of melted butter and ½ teaspoon of vanilla extract, then mix until a smooth dough forms. Press the dough evenly into a tart pan and chill in the refrigerator for 30 minutes to firm up and set.
Step 2: Make the Custard
In a saucepan, whisk together 3 egg yolks, 2 whole eggs, 1 cup of white sugar, ⅓ cup of cornstarch, and ½ teaspoon of salt until well combined. Gradually stir in 2 ½ cups of whole milk and 1 ¾ cups of heavy cream. Cook over medium heat, continuously whisking for about 10 minutes until the mixture thickens. Remove from heat and stir in 7 oz of dark chocolate until completely melted and smooth.
Step 3: Assemble and Bake
Preheat the oven to 350°F (175°C). Remove the chilled tart crust from the refrigerator and pour the creamy custard mixture into the crust. Bake in the preheated oven for 35-40 minutes, or until the edges are set but the center is still slightly wobbly. Once baked, remove from the oven and allow to cool at room temperature.
Step 4: Finish and Serve
Once the French chocolate flan has cooled, brush the top with 1 tablespoon of your chosen jam to achieve a glossy finish. Chill the flan in the refrigerator for at least 2 hours before slicing, allowing the flavors to meld beautifully. Serve cold or at room temperature, enhancing each piece with fresh berries or a dollop of whipped cream if desired.

How to Store and Freeze French Chocolate Flan
Fridge: Cover the flan with plastic wrap or aluminum foil and store in the refrigerator for up to 3 days. For the best texture and taste, enjoy within 2 days.
Freezer: For longer storage, freeze the French chocolate flan wrapped tightly in plastic wrap and then aluminum foil. It can keep for up to 2 months. Thaw overnight in the fridge before serving.
Reheating: To enjoy it again, allow the flan to come to room temperature after thawing. If needed, you can warm individual slices in the microwave briefly, but be careful not to overheat.
Serving: After storage, freshen up the flan by brushing with a bit more jam before serving to restore its glossy appearance and those sweet flavors!
Expert Tips for French Chocolate Flan
Constant Whisking: Ensure you whisk continuously while preparing the custard to avoid curdling; this keeps the texture smooth and creamy.
Watch the Time: Keep an eye on your baking time; overbaking can lead to a dry custard, ruining the velvety consistency of your French chocolate flan.
Cooling is Key: Allow the flan to cool completely before slicing; this enhances the flavors and makes it easier to cut perfect pieces.
Chill for Flavor: Refrigerate the flan for at least two hours before serving; chilling allows the flavors to meld together beautifully for a luxurious taste.
Decorate Thoughtfully: Brush the top with jam for a glossy finish, but avoid overdoing it—too much can distract from the flan’s rich chocolate beauty.
Make Ahead Options
These French Chocolate Flan are perfect for meal prep and can be made up to 24 hours in advance! To save time, you can prepare the tart base and custard separately: simply make the tart crust and store it covered in the refrigerator. The custard can also be cooked and cooled, then kept in an airtight container for up to 3 days. When you’re ready to serve, gently reheat the custard if it’s been refrigerated, and pour it into the chilled tart shell. Allow it to set briefly before brushing with jam. This make-ahead strategy not only saves you time but also enhances the flavors, ensuring your French Chocolate Flan is just as delicious when you serve it!

French Chocolate Flan Recipe FAQs
How do I select the best chocolate for my French chocolate flan?
Absolutely! For the richest flavor, opt for high-quality dark chocolate with at least 60% cacao. Look for chocolate that has a smooth texture and minimal additives to ensure a delightful, luxurious taste in your flan.
What’s the best way to store leftover French chocolate flan?
Very! To store your leftover flan, cover it tightly with plastic wrap or aluminum foil and refrigerate. It will last up to 3 days, but for the best flavor and texture, I recommend enjoying it within the first 2 days. Always remember to bring it to room temperature before serving for the best experience!
Can I freeze French chocolate flan? How do I do it?
Absolutely! You can freeze the flan for up to 2 months. First, ensure it is completely cooled, then wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. To thaw, simply place it in the refrigerator overnight. If you want to serve it warm, you can briefly heat individual slices in the microwave, but do so cautiously to avoid overheating.
Why did my custard curdle during cooking?
Oh no! Curdling can often happen if the heat is too high or if the custard isn’t whisked constantly. Always cook the custard over medium heat and whisk continuously to maintain a smooth texture. If you find your custard has begun to curdle, you may try blending it again once it’s cooled slightly for a smoother consistency.
Can I make this recipe dairy-free?
Definitely! To make a dairy-free version of the French chocolate flan, substitute whole milk with almond milk or oat milk, and replace heavy cream with coconut cream. The dark chocolate should also be dairy-free. These substitutions will maintain the richness without sacrificing flavor!
Is there a way to make this dessert nut-free?
Absolutely! If you need to avoid nuts, ensure your chocolate does not contain any nut-based components, and stick with lactose-free dairy alternatives. All other ingredients in the flan are naturally nut-free, making this delectable dessert suitable for various dietary needs!
