French Chocolate Flan Ingredients
For the Custard
- Egg Yolks (3) – Adds richness and structure to the custard. No direct substitute; for a vegan version, consider silken tofu or a vegan custard powder.
- Whole Eggs (2) – Provides additional structure and helps bind the custard. Substituting with flax eggs is possible for a vegan option.
- White Sugar (1 cup / 200g) – Sweetens the custard. Brown sugar can add a slight caramel flavor.
- Cornstarch (⅓ cup / 42g) – Thickens the custard for a smooth consistency. Arrowroot powder can be used as a substitute.
- Salt (½ teaspoon) – Enhances flavor and balances sweetness. Important for flavor profile; no substitute necessary.
- Whole Milk (2 ½ cups / 600ml) – Forms the base of the custard. Almond milk can be a non-dairy alternative.
- Heavy Cream (1 ¾ cups / 400ml) – Adds richness and creaminess. Coconut cream works as a vegan substitute.
- Dark Chocolate (7 oz / 200g, chopped) – Main flavor component; contributes richness. Use semi-sweet chocolate for a sweeter taste.
- Jam (1 tablespoon for brushing) – Adds shine and aesthetic appeal. Apricot or raspberry preserves can be used for flavor variation.
For the Chocolate Tart Base
- All-Purpose Flour (1 cup / 120g) – Provides structure. For gluten-free, use a gluten-free flour blend.
- Icing Sugar (⅓ cup / 35g) – Sweetens and gives a tender texture to the crust. Regular sugar can be substituted but may alter texture slightly.
- Cocoa Powder (¼ cup / 25g) – Enhances chocolate flavor in the crust. Carob powder can be a non-cocoa alternative.
- Salt (¼ teaspoon) – Balances sweetness in the tart. Essential to enhance flavors.
- Butter (1 stick / 114g, melted) – Binds crust ingredients and adds richness. Vegan butter can be used for a dairy-free version.
- Vanilla Extract (½ teaspoon) – Adds a warm flavor profile. Use quality pure extract for best results.
Step‑by‑Step Instructions for French Chocolate Flan
Step 1: Prepare the Tart Base
In a large mixing bowl, combine the all-purpose flour, icing sugar, cocoa powder, and salt, ensuring even distribution. Pour in the melted butter and vanilla extract, mixing until a cohesive dough forms. Press the dough evenly into the bottom and sides of a tart pan. After shaping, chill the pan in the refrigerator for 30 minutes to firm up the crust.
Step 2: Preheat Oven
While your tart crust chills, preheat your oven to 350°F (175°C). This temperature is perfect for blind baking the crust and achieving that delightful crispness. Ensure your oven has reached this temperature before proceeding to the next step for optimal baking results.
Step 3: Blind Bake the Tart Crust
Once the oven is ready, line your chilled tart crust with parchment paper and fill it with baking weights or dried beans. Bake in the preheated oven for 15-20 minutes until the edges are lightly golden. Carefully remove the weights and parchment, then bake for an additional 5 minutes until the crust is set. Allow it to cool completely before proceeding.
Step 4: Make the Chocolate Custard
In a medium saucepan over medium heat, whisk together the egg yolks, whole eggs, sugar, cornstarch, and salt until well combined. Gradually whisk in the whole milk and heavy cream, stirring continuously as you cook. Heat until the mixture thickens and coats the back of a spoon, about 6-8 minutes. Remove from heat and stir in the chopped dark chocolate until melted and smooth, creating your rich chocolate custard.
Step 5: Combine and Bake
Carefully pour the chocolate custard into the cooled tart crust, spreading it evenly with a spatula. Place the tart back into the oven and bake for 30-35 minutes, or until the custard is just set in the center. You should see a slight jiggle while the edges should be firm. This step is crucial for a perfect French Chocolate Flan.
Step 6: Cool & Serve
Once baked, remove the tart from the oven and let it cool at room temperature for about 30 minutes. Then, refrigerate the flan for at least 4 hours, or overnight for the best flavor. Before serving, brush the top with your choice of jam for a beautiful glossy finish and a hint of sweetness. Slice and present to enjoy the luxurious flavors of your homemade French Chocolate Flan!

French Chocolate Flan Recipe FAQs
What is the best way to select ripe ingredients for the French Chocolate Flan?
Absolutely! When selecting your eggs, look for those that are fresh and have bright, vibrant yolks—this indicates quality and freshness, which is essential for a rich custard. Choose dark chocolate with a high cocoa content (at least 70%) for a deeply satisfying flavor. For the cream and milk, opt for organic, if possible, to enhance the overall taste of your dessert.
How should I store French Chocolate Flan?
The best way to store your French Chocolate Flan is by covering it tightly and placing it in the refrigerator, where it can last for up to 3 days. If you make it ahead of time, it’s even better! The flavors will deepen and become richer. Just ensure it’s completely cool before storing to maintain that lovely texture.
Can I freeze French Chocolate Flan?
Very! To freeze your French Chocolate Flan, wrap it tightly in plastic wrap, then cover it with aluminum foil to prevent freezer burn. It can be frozen for up to 2 months. When you’re ready to enjoy it, thaw the flan overnight in the fridge. This method preserves its creamy texture and rich taste beautifully!
What if my custard is too runny?
If your custard hasn’t thickened as expected, don’t fret! You can return it to the heat gently, whisking constantly to prevent curdling. If it remains runny after baking, it likely needs more time—risk a gentle jiggle in the center. Ensure you’re cooking the custard mixture over medium heat, stirring continuously until it coats the back of a spoon, typically about 6-8 minutes. Patience is key here!
Are there any dietary considerations with the ingredients used in French Chocolate Flan?
Of course! If you have dietary restrictions, there are excellent alternatives. For a dairy-free version, substitute whole milk with almond or soy milk, and use coconut cream instead of heavy cream.
