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 icing sugar, ¼ cup cocoa powder, and ¼ teaspoon salt. Pour in 114g of melted butter and ½ teaspoon vanilla extract, and mix until a dough forms. Press the dough evenly into the bottom and sides of a tart pan, then chill for at least 30 minutes to firm up.
Step 2: Make the Chocolate Custard
In a separate bowl, whisk together 6 egg yolks, 2 whole eggs, 1 cup sugar, ⅓ cup cornstarch, and ½ teaspoon salt until well combined and pale. In a saucepan, heat 2 ½ cups whole milk and 1 ¾ cups heavy cream over medium heat until just boiling. Gradually pour the hot mixture over the egg mixture while whisking continuously to prevent curdling.
Step 3: Add the Chocolate
Once combined, stir in 200g of chopped dark chocolate into the warm custard until it melts completely and the mixture is smooth and glossy. This is the rich, chocolatey core of your French Chocolate Flan, and it’s important to ensure the chocolate is fully incorporated for an even flavor throughout.
Step 4: Bake the Flan
Preheat your oven to 350°F (175°C). Pour the chocolate custard gently into the prepared tart crust. Bake for 45-50 minutes, or until the edges are set and the center has a slight jiggle—it will firm up as it cools. Keep an eye on it towards the end to prevent overbaking, which can impact texture.
Step 5: Cool and Finish
Once baked, remove the flan from the oven and allow it to cool at room temperature for about 30 minutes. Brush the top with 1 tablespoon of jam for a beautiful glaze. Refrigerate the French Chocolate Flan for at least 2 hours, allowing it to set completely and develop its decadent flavors.
