French Chocolate Flan Ingredients

For the Custard

Egg Yolks (3 yolks) – Adds richness and color to the custard. No substitutions; crucial for texture.
Whole Eggs (2) – Provide structure and stability to the custard. Could use egg substitutes for a vegan version, but texture may differ.
White Sugar (1 cup/200g) – Sweetens the custard. Can substitute with coconut sugar for a less refined option.
Cornstarch (⅓ cup/42g) – Thickening agent for the custard, giving it a smooth consistency. Can use arrowroot powder as a substitute.
Salt (½ teaspoon) – Enhances flavor of the dessert. No substitutes; essential for balance.
Whole Milk (2½ cups/600ml) – Base for the custard, lending creaminess. Almond milk may be used for a dairy-free version, but may alter flavor.
Heavy Cream (1½ cups/400ml) – Adds richness and creaminess. Substitute with coconut cream for a dairy-free option.
Dark Chocolate (7 oz/200g, chopped) – Provides the chocolate flavor intensity in the custard. Can be substituted with semi-sweet chocolate for a sweeter taste.

For the Tart Base

All-Purpose Flour (1 cup/120g) – Forms the chocolate tart base. Gluten-free flour could be used for a gluten-free version.
Icing Sugar (⅓ cup/35g) – Sweetens the tart base and helps in creating a tender texture. Regular sugar can work but may affect texture slightly.
Cocoa Powder (¼ cup/25g) – Adds chocolate flavor and color to the tart crust. No substitutes; important for the cocoa taste.
Salt (¼ teaspoon) – Balances the sweetness of the tart base. No substitutes.
Butter (1 stick/114g, melted) – Binds the tart base and adds richness. Vegan butter can be used as a substitute.
Vanilla Extract (½ teaspoon) – Enhances the flavors of the custard and tart. No direct substitutes, though vanilla paste could be used for a richer taste.

Finishing Touches

Jam (1 tablespoon, for brushing on top) – Provides a glossy finish; apricot jam works well. No direct substitutes, but can skip for a simpler finish.

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 well until evenly blended. Then, add 1 stick of melted butter and ½ teaspoon of vanilla extract, stirring until a dough forms. Press this dough evenly into a tart pan, ensuring it’s compact, and refrigerate for about 30 minutes to chill.

Step 2: Make the Chocolate Custard
In a separate bowl, whisk together 3 egg yolks and 2 whole eggs until well combined. Over medium heat in a saucepan, whisk together 1 cup of white sugar, ⅓ cup of cornstarch, and ½ teaspoon of salt. Gradually stir in 2½ cups of whole milk and 1½ cups of heavy cream, heating until warmed but not boiling, stirring constantly to avoid scorching.

Step 3: Combine Chocolate and Egg Mixture
Remove the saucepan from heat and stir in 7 ounces of chopped dark chocolate until melted and the mixture is smooth. Gradually incorporate the egg yolk mixture into the warm chocolate mixture, whisking continuously to ensure the eggs don’t curdle, resulting in a velvety chocolate custard essential for your French Chocolate Flan.

Step 4: Bake the Flan
Preheat your oven to 350°F (175°C). Once the tart base has chilled, pour the chocolate custard mixture into the prepared tart shell, filling it evenly. Bake for about 30-40 minutes, or until the custard is set but still slightly jiggly in the center. Remove from the oven and allow to cool completely at room temperature.

Step 5: Chill for Optimal Texture
After cooling, cover the flan with plastic wrap and refrigerate for a minimum of 4 hours, or until fully chilled. This chilling time allows the flavors to develop and the custard to firm up, giving your French Chocolate Flan the perfect texture for slicing and serving.

Step 6: Add the Finishing Touch
Before serving, gently heat 1 tablespoon of jam in the microwave until warm and brush it over the top of the chilled flan to create a glossy finish. Slice the flan into wedges and present it chilled, and get ready to impress your guests with this luxurious dessert!
