- 1 1/2 cups (360ml) whole milk (or evaporated milk for extra richness)
- 1/3 cup (35g) unsweetened cocoa powder
- 2 teaspoons vanilla extract
- Pinch of salt
For the Crispy Walnuts

- 2 tablespoons brown sugar
- 1 tablespoon butter

Preparation Time
- Prep time: 20 minutes
- Bake time: 45–55 minutes
- Cooling time: 1 hour
- Chill time: 4–6 hours (or overnight)
- Total time: About 6–8 hours
Step-by-Step Instructions
Step 1: Preheat and Prep
Preheat oven to 325°F (165°C). Place a kettle of water on to heat (you’ll need hot water for a water bath).
Have an 8–9 inch round cake pan or flan mold ready.
Step 2: Make the Caramel
In a saucepan, combine sugar and water. Cook over medium heat without stirring (swirl the pan gently) until it turns a deep amber color.
Quickly pour caramel into your pan and tilt to coat the bottom evenly. Set aside to harden.
Step 3: Mix the Chocolate Custard
In a bowl, whisk eggs until blended (don’t whip too much). Add condensed milk, milk, cocoa powder, vanilla, and salt. Whisk until smooth.
For extra smooth flan, strain the mixture through a fine sieve.
Step 4: Pour and Prepare the Water Bath
Pour custard over the hardened caramel. Place the pan inside a larger roasting pan.
Carefully pour hot water into the roasting pan until it reaches halfway up the sides of the flan pan.
Step 5: Bake
Bake for 45–55 minutes, until the edges are set and the center still jiggles slightly.
Remove from oven and water bath carefully.
Step 6: Cool and Chill
Let cool at room temperature for 1 hour, then cover and refrigerate for 4–6 hours (overnight is best).
Step 7: Make Crispy Walnuts
In a skillet over medium heat, melt butter. Add walnuts, brown sugar, and salt. Stir for 3–5 minutes until toasted and glossy.
Spread on parchment paper to cool and crisp.
Step 8: Unmold and Serve
Run a thin knife around the flan edge. Place a serving plate on top and flip quickly.
Let caramel drizzle over the flan, then top with crispy walnuts.
Serving Suggestions
- Serve chilled with extra caramel spooned over the top.
- Add whipped cream for a light, creamy contrast.
- Sprinkle with cocoa powder or chocolate shavings for a “gourmet” finish.
- Pair with fresh berries or orange slices to brighten the richness.
