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. Pour in 1 stick of melted butter and add ½ teaspoon of vanilla extract. Mix until a soft dough forms, then press it evenly into the bottom of a 9-inch tart pan. Chill the tart base in the refrigerator for 30 minutes to firm up.
Step 2: Make the Chocolate Custard
While the tart base chills, whisk together 3 egg yolks, 2 whole eggs, and 1 cup of white sugar in a saucepan. Gradually stir in ⅓ cup of cornstarch until smooth, then add 2½ cups of whole milk and 1⅓ cups of heavy cream. Heat over medium heat for about 10 minutes, stirring continuously until the mixture thickens and bubbles gently. Remove from heat and stir in 7 oz of chopped dark chocolate until completely melted and smooth.
Step 3: Bake the Flan
Preheat your oven to 350°F (175°C). Carefully pour the rich chocolate custard into the prepared tart shell, smooth the surface with a spatula. Place the tart pan on a baking sheet to catch any drips, then bake in the preheated oven for 30-35 minutes, or until the center is just set but still slightly wobbly. Keep an eye on it to avoid overbaking.
Step 4: Cool & Glaze
Once baked, remove the French chocolate flan from the oven and let it cool at room temperature for about 1 hour. After cooling, brush the top lightly with 1 tablespoon of jam to create a glossy finish. Once completely cooled, refrigerate for at least 3 hours to firm up the custard before serving.
Step 5: Serve and Enjoy
Once chilled, carefully slice the flan with a sharp knife. For a beautiful presentation, serve each slice with a few fresh berries or a dollop of whipped cream. The French chocolate flan, with its luxurious custard and crispy tart base, is now ready to delight you and your guests!

Make Ahead Options
Preparing your French Chocolate Flan in advance is a fantastic way to save time, especially for busy weeknights or special occasions! You can prepare the tart base up to 24 hours ahead; simply press the dough into the tart pan and refrigerate it until you’re ready to bake. The chocolate custard can also be made up to 3 days in advance; after cooking, let it cool completely, pour it into the tart shell, and then cover it with plastic wrap to maintain freshness in the refrigerator. When you’re ready to serve, bake the flan as instructed and allow it to chill for a few hours before cutting into it—this ensures a creamy and luxurious result that tastes just as delicious as when freshly made!

Chill for Best Flavor: Allow the flan to chill in the refrigerator for at least three hours; this not only sets the custard but also enhances the flavors.

French Chocolate Flan Recipe FAQs
What type of dark chocolate should I use for the flan?
Absolutely! For the best results, I recommend using high-quality dark chocolate with at least 70% cocoa content. This will ensure a rich and deep chocolate flavor in your custard. Look for chocolate bars rather than chips, as they tend to melt more smoothly and integrate better into the mixture.
How should I store leftover French chocolate flan?
Very! Store your French chocolate flan in the refrigerator, covered with plastic wrap or in an airtight container, for up to 3 days. This will help maintain its creamy texture and prevent it from drying out. If you find yourself with leftovers, you can also freeze individual slices for up to 2 months. Wrap them tightly in plastic wrap and place them in an airtight container.
Can I freeze French chocolate flan? How?
Yes, you can! To freeze, wrap individual slices tightly in plastic wrap and then place them in an airtight container. This way, they won’t absorb any unwanted odors from the freezer. When you’re ready to enjoy a slice, simply thaw it in the refrigerator overnight. For a quick treat, you can microwave a slice for about 15-20 seconds to warm it up—though I personally love it chilled!
What should I do if my custard is lumpy?
Oh no! If your custard becomes lumpy, it might mean it was heated too quickly or not stirred enough while cooking. To fix this, try using an immersion blender or a regular blender to smooth it out before pouring it into the tart shell. If you’ve already poured it in and baked it, don’t worry too much—the delicious flavors will still be there, but make sure to keep an eye on the stirring next time!
Are there any dietary considerations for this recipe?
Absolutely! If you have dietary restrictions, you can make a few adjustments. For a dairy-free version, substitute whole milk and heavy cream with non-dairy alternatives like almond or oat milk combined with a suitable dairy-free cream. Additionally, ensure that any chocolate and other ingredients you use are free from allergens like dairy or gluten, especially if you have guests with allergies.
What should I do if I don’t have all-purpose flour for the tart base?
No worries! You can substitute the all-purpose flour with a 1:1 gluten-free flour blend if necessary. Alternatively, for a different flavor, try using almond flour—it will give the crust a slightly nutty taste and can be quite delicious! Just remember that the texture might change slightly, but it will still be a fantastic sweet foundation for your flan.
