Decadent Chocolate Flan with Sesame Brittle

The memory still warms me – my Abuela Elena, humming a tune as old as the volcanic rock in her garden, pulling a shimmering, mahogany-colored flan from the oven. The aroma of caramelized sugar and rich cocoa would fill her tiny kitchen, a beacon calling us grandchildren in from our games. It wasn’t just dessert; it was a symbol of her love, poured into every creamy, trembling spoonful. I’ve spent years trying to recreate that magic, and I’m thrilled to share my version of this classic, infused with the deep, comforting flavor of chocolate and the surprising crunch of sesame brittle.

Instructions

To begin, create the caramel base. Place ½ cup of the granulated sugar in a small saucepan over medium heat. Allow the sugar to melt undisturbed until it begins to turn brown around the edges.
Using a heatproof rubber spatula, gently pull the melted sugar from the edges towards the center of the unmelted sugar. This helps to ensure even melting and prevents burning.
Continue cooking, constantly pulling in the melted sugar, until all of the sugar is melted and transformed into a caramel that is uniformly dark brown. The caramel should smell toasty and rich, but not burnt, which can impart a bitter flavor. This process should take about 10–12 minutes total. If you still have undissolved lumps of sugar, remove the saucepan from the heat and stir until they melt completely.
Carefully pour the hot caramel into the 8-inch diameter cake pan, creating an even layer that is approximately ⅛”–¼” deep. Tilt the pan to ensure the caramel coats the bottom evenly. Set aside and allow the caramel to cool completely and harden.
Next, prepare the chocolate infusion. In a medium saucepan, bring 1 cup of water to a simmer over medium-high heat.
Whisk in the cocoa powder until it is fully dissolved and no lumps remain. This step is crucial for a smooth and silky flan.
Add the heavy cream, whole milk, split vanilla bean, and crushed ceylon cinnamon sticks to the saucepan and return the mixture to a simmer.
Remove the saucepan from the heat and let the chocolate mixture steep for 30 minutes. This allows the flavors to meld and deepen.
While the chocolate mixture steeps, prepare for the baking process. Place a rack in the middle of the oven and preheat to 350°F (175°C). Bring a large pot of water to a boil.
In a blender, combine the eggs, remaining ½ cup granulated sugar, and ¼ teaspoon kosher salt. Purée the mixture until it is smooth and the sugar is completely dissolved, approximately 1 minute.
Strain the steeped chocolate mixture through a fine-mesh strainer into the egg mixture, discarding the solids (vanilla bean and cinnamon sticks). Blend on low speed to combine the two mixtures.
Skim any foam that forms on the surface of the mixture. This will help to create a smoother flan. Gently pour the chocolate-egg mixture into the prepared cake pan with the cooled caramel.
Line a roasting pan with a thick kitchen towel. This serves two purposes: it prevents the baking dish from sliding around in the water bath and it insulates the flan, preventing it from overcooking.
Set the cake pan containing the flan mixture on the towel inside the roasting pan. Carefully place the roasting pan in the preheated oven.
Pour the boiling water into the roasting pan until it reaches the same level as the flan mixture in the cake pan. This creates a water bath that gently and evenly cooks the flan.
Bake the flan until it appears set, resembling Jell-O in consistency – it should wobble slightly when gently shaken. This will typically take 35–45 minutes.
Carefully remove the roasting pan from the oven. Transfer the cake pan containing the flan to a wire rack and allow it to cool to room temperature.
Once cooled, cover the cake pan with plastic wrap and chill in the refrigerator until completely set and cold, at least 3 hours, or preferably overnight (up to 24 hours).
While the flan is chilling, prepare the sesame brittle. Increase the oven temperature to 350°F (175°C).
In a small bowl, toss the sesame seeds, agave syrup, and ¼ teaspoon kosher salt together until the seeds are evenly coated.
Scrape the sesame seed mixture onto a silpat mat or a piece of parchment paper placed on a rimmed baking sheet. Spread the mixture into an even layer.
Bake the sesame brittle until the sesame seeds are golden brown and the syrup is bubbly, approximately 15–20 minutes.
Remove the baking sheet from the oven and let the sesame brittle cool completely until hardened.
Once the brittle is cooled and hardened, break it up into small pieces. Discard any pieces that are very dark brown or have a bitter taste.
To unmold the flan, run a small knife around the edges of the cake pan to loosen it from the sides.
Invert the flan onto a serving platter. The caramel will now be on top, creating a beautiful and delicious sauce.
Garnish the flan with the crushed sesame brittle just before serving.

Expert Tips & Tricks

Don’t burn the caramel! This is the most common mistake. Low and slow is key. If you smell burning, immediately remove the pan from the heat.
Use Dutch-processed cocoa powder. It has a smoother, richer flavor and will give your flan a deeper chocolate color.
The water bath is crucial. It prevents the flan from curdling and ensures a silky smooth texture. Make sure the water level reaches at least halfway up the sides of the cake pan.
Don’t overbake the flan. It should still wobble slightly when gently shaken. It will continue to set as it cools.
For an even smoother flan, strain the egg mixture through a fine-mesh sieve a second time before pouring it into the cake pan.

Serving & Storage Suggestions

Serve the chocolate flan chilled, garnished with the crushed sesame brittle. The contrast between the creamy flan, the rich caramel, and the crunchy sesame is heavenly. Leftover flan should be stored in an airtight container in the refrigerator. It will keep for up to 3 days. The sesame brittle is best stored separately in an airtight container at room temperature to maintain its crispness. Reheating is not recommended, as it can affect the texture of the flan.

Coffee Chocolate Flan: Add 1-2 tablespoons of instant espresso powder to the chocolate mixture for a mocha flavor.
Boozy Chocolate Flan: Add a tablespoon of your favorite liquor, such as rum or Kahlua, to the chocolate-egg mixture before baking.
Gluten-Free: While the flan itself is gluten-free, the sesame brittle might be prepared with ingredients containing gluten. Be sure to use certified gluten-free agave syrup.
Less Sweet: Use a sugar substitute in the brittle and reduce the sugar in the flan custard by 2 tablespoons.

FAQs (Frequently Asked Questions)

Q: Can I make the flan without a blender?
A: Yes, you can whisk the eggs and sugar together vigorously until smooth, but a blender ensures the mixture is fully emulsified for a smoother final texture.

Q: How do I know if the flan is done?
A: The flan is done when it jiggles slightly when shaken gently. It should look set around the edges but still have a slight wobble in the center.

Q: Can I use a different size cake pan?
A: Using a different size pan will affect the cooking time. A smaller pan will require a longer cooking time, while a larger pan will require a shorter cooking time. Keep an eye on the flan and adjust accordingly.

Q: Can I make the sesame brittle ahead of time?
A: Yes, the sesame brittle can be made up to 2 days in advance and stored in an airtight container at room temperature.

Q: Why did my flan curdle?
A: Overbaking is the most common cause of curdled flan. Make sure to use a water bath and check the flan frequently during baking.
