Melt the sugar with the water in a saucepan over medium heat without stirring until you get a golden, amber caramel, then immediately pour it into the bottom of a twenty-centimeter square pan.
Melt the dark chocolate with the butter in a double boiler or in the microwave at low power, then smooth with a spatula.
Add the sugar to the slightly cooled chocolate mixture, beat in the eggs one at a time, then finish with the flour and salt without overworking the batter.
Gently spread the brownie batter over the set caramel in the pan using the spatula.
Whisk the eggs with the sweetened condensed milk, whole milk and vanilla extract in a bowl until fluid and smooth, then gently pour this mixture over the brownie batter.
Place the pan in a large baking dish, pour boiling water halfway up the pan to form the water bath, then bake for until the surface of the flan is set and firm to the touch.
Let cool at room temperature, then refrigerate for at least so the two layers set perfectly.
Run a thin blade along the sides, unmold the cake onto a serving platter, cut into square pieces and garnish with fresh mint before serving.

Good to know

Chef's tip

To keep the separation between the two layers clean when slicing, pour the flan mixture very slowly over the back of a spoon above the brownie layer. During baking, the densities naturally swap places.

Freezing : Can you freeze this recipe?

Yes

Very well, up to 2 months in an airtight or wrapped container.

Storage : How long does it keep?

Keeps 3 to 4 days max in an airtight container in the fridge.

Making ahead : Can you make it the day before?

Yes

Ideally prepared the day before for better texture and flavor.

Reheating : How do you reheat it?

Usually eaten cold or at room temperature. Reheating not recommended (affects texture).

Variations

  • Coffee version: add a teaspoon of coffee extract or strong coffee to the flan mixture for a tiramisu-like flavor profile.
  • Gluten-free version: replace the wheat flour in the brownie with an equal amount of cornstarch.
  • Pecan version: sprinkle chopped pecans over the brownie batter before pouring in the flan to add crunch.

Mistakes to avoid

  • Unmolding the cake while still warm, which would make the creamy texture of the flan collapse.
  • Baking without a water bath, which would dry out the brownie and make the flan grainy with air bubbles.
  • Whisking the flan mixture too vigorously, creating too much foam that interferes with the surface setting.

Frequently asked questions

Why do the layers swap during baking?

The brownie batter, denser but aerated by the fat, slowly rises while the liquid flan mixture slides to the bottom on contact with the caramel, creating two distinct layers.

Can I use store-bought liquid caramel?

Yes, you can coat the bottom of the pan with ready-to-use liquid caramel, although homemade caramel gives a more amber color and a deeper flavor.

How do I know if the brownie flan is cooked?

Insert a knife blade into the center: it should come out clean from the flan, with a slightly jiggly texture in the middle that will set completely while resting in the refrigerator.

What type of chocolate should I use for the brownie?

Choose a dark baking chocolate between 50 and 70% cocoa to balance the very sweet side of the caramel and the condensed milk flan.
