Flan cake, also known as chocoflan or impossible cake, is a mesmerizing dessert that combines the creamy, silky texture of flan with the rich, moist crumb of chocolate cake. The magic lies in its self-layering process during baking, where the batter somehow switches positions, leaving the flan on top and the cake at the bottom. This impressive dessert is easier to make than you might think, and this comprehensive guide will walk you through each step to create a flawless chocoflan that will wow your family and friends.
Understanding the Magic of Chocoflan
Before diving into the recipe, it’s helpful to understand why the cake and flan layers switch places during baking. This phenomenon is due to the differences in density and viscosity between the two batters. The chocolate cake batter is lighter and less dense than the flan mixture. As the cake bakes, it rises, and the denser flan mixture sinks beneath it. Once the cake is cooked, the layers invert again when you unmold the cake, revealing the smooth flan topping. Understanding this density difference is crucial for achieving the perfect layered result.

Making the Flan Cake: Step-by-Step Instructions
Now that you have all your ingredients and equipment ready, let’s get started on making this delicious dessert.
Step 1: Preparing the Caramel
The caramel layer is the foundation of the flan and adds a rich, sweet flavor. It’s crucial to get the caramel right, as it will impact the overall taste and texture of the flan.
- In a heavy-bottomed saucepan, combine the granulated sugar and water.
- Cook over medium heat, stirring constantly until the sugar dissolves.
- Once the sugar is dissolved, stop stirring and let the mixture simmer until it turns a deep amber color. This process usually takes about 8-10 minutes.
- Immediately pour the caramel into the bottom of your 9-inch fluted tube pan, tilting the pan to coat the bottom evenly.
- Let the caramel cool and harden while you prepare the flan and cake layers. Be careful, hot caramel can cause serious burns.
Step 2: Making the Flan Layer
The flan layer is what makes this dessert so special, giving it that creamy, melt-in-your-mouth texture.
- In a large mixing bowl, combine the sweetened condensed milk, evaporated milk, eggs, and vanilla extract.
- Whisk all the ingredients together until well combined and smooth. Avoid over-mixing, as this can introduce air bubbles that will affect the texture of the flan.
- Gently pour the flan mixture over the hardened caramel in the tube pan.
Step 3: Preparing the Chocolate Cake Layer
The chocolate cake adds a rich, contrasting flavor and texture to the flan, creating a delightful combination.
- Prepare the chocolate cake batter according to the instructions on the box or your favorite homemade recipe.
- Ensure the cake batter is smooth and free of lumps.
- Gently pour the chocolate cake batter over the flan mixture in the tube pan. Don’t worry if it seems like the cake batter will sink – that’s exactly what’s supposed to happen.
Step 4: Baking the Flan Cake
Baking the flan cake requires a water bath, which helps to ensure even cooking and prevents the flan from cracking.
- Preheat your oven to 350°F (175°C).
- Place the tube pan containing the flan and cake batter inside a larger baking sheet.
- Carefully pour hot water into the baking sheet, reaching about halfway up the sides of the tube pan. This creates a water bath, also known as a bain-marie.
- Bake for approximately 1 hour and 15 minutes to 1 hour and 30 minutes, or until a toothpick inserted into the cake comes out clean. The flan should be set but still slightly jiggly.
- Remove the baking sheet from the oven and carefully remove the tube pan from the water bath.
- Let the flan cake cool completely at room temperature.
- Once cooled, cover the tube pan with plastic wrap and refrigerate for at least 4 hours, or preferably overnight. Chilling the cake thoroughly will make it easier to unmold.
Step 5: Unmolding and Serving
This is the moment of truth – unmolding the flan cake to reveal its beautiful layers.
- Run a thin knife or spatula around the edges of the flan cake to loosen it from the sides of the tube pan.
- Place a serving plate over the top of the tube pan.
- Invert the pan onto the serving plate, holding it firmly.
- Gently shake or tap the pan to release the flan cake. The caramel should drizzle down the sides of the cake, creating a beautiful presentation.
- Slice and serve. The flan cake is best served chilled.
Tips and Tricks for the Perfect Flan Cake
Here are some additional tips to help you achieve a flawless flan cake:
- Don’t overbake: Overbaking can cause the flan to become rubbery and the cake to be dry.
- Use a water bath: The water bath is essential for even cooking and prevents the flan from cracking.
- Let it cool completely: Cooling the flan cake completely before refrigerating helps it to set properly.
- Refrigerate overnight: Refrigerating the flan cake overnight allows the flavors to meld and makes it easier to unmold.
- Grease the pan lightly: Some bakers like to grease and flour the bundt pan before adding the caramel, to further ensure easy unmolding.
Variations and Additions
While the classic flan cake is delicious on its own, there are many ways to customize it to your liking. Here are a few ideas:
- Coffee Flan Cake: Add 1-2 tablespoons of instant coffee granules to the flan mixture for a coffee-flavored twist.
- Coconut Flan Cake: Substitute coconut milk for some of the evaporated milk in the flan mixture.
- Dulce de Leche Flan Cake: Swirl dulce de leche into the flan mixture before baking.
- Spiced Flan Cake: Add a pinch of cinnamon, nutmeg, or cardamom to the flan or cake batter.
- Chocolate Variations: Use different types of chocolate cake mixes, such as dark chocolate or devil’s food cake.
Troubleshooting Your Flan Cake
Even with the best instructions, things can sometimes go wrong. Here are some common problems and how to fix them:
- Flan is rubbery: This is usually caused by overbaking. Reduce the baking time next time.
- Cake is dry: This can also be caused by overbaking. Make sure to use a water bath and don’t overbake the cake.
- Flan doesn’t set: This could be due to not enough eggs or not enough baking time.
- Cake and flan layers didn’t switch: This could be due to the densities of the batters not being different enough, or the batter was mixed improperly. Ensure you follow the recipes closely.
- Cake sticks to the pan: Make sure the caramel has cooled completely before pouring in the flan mixture. Running a knife around the edge before unmolding can help.
Serving Suggestions
Flan cake is a versatile dessert that can be enjoyed in many ways. Here are a few serving suggestions:
- Plain: Simply slice and serve the flan cake on its own.
- With whipped cream: Top each slice with a dollop of freshly whipped cream.
- With fresh fruit: Garnish with fresh berries, sliced peaches, or other seasonal fruits.
- With chocolate sauce: Drizzle chocolate sauce over the flan cake for an extra decadent treat.
- With caramel sauce: Enhance the caramel flavor by drizzling additional caramel sauce over the cake.
Storing Leftover Flan Cake
Leftover flan cake can be stored in the refrigerator for up to 3-4 days. Cover it tightly with plastic wrap or store it in an airtight container to prevent it from drying out. The caramel may soften over time, but the flavor will still be delicious.

What is chocoflan, and what makes it unique?
Chocoflan, also known as “impossible cake” or “magic cake,” is a dessert that consists of a layer of chocolate cake and a layer of flan, baked together in a single pan. What makes it truly unique is the way the layers magically switch during baking, with the chocolate cake sinking to the bottom and the flan rising to the top, creating a visually stunning and delicious dessert.
The transformation occurs due to the difference in density between the two batters. The flan batter is denser than the chocolate cake batter. As the cake bakes, it rises, and the denser flan batter slips underneath. The caramel at the bottom further anchors the flan in place, solidifying its position as the top layer after baking and inverting.
What ingredients are essential for making a good chocoflan?
The essential ingredients for chocoflan can be divided into three main components: the caramel, the flan, and the chocolate cake. For the caramel, you need granulated sugar. For the flan, you’ll need eggs, sweetened condensed milk, evaporated milk, vanilla extract, and potentially cream cheese for a richer texture. The chocolate cake requires the standard ingredients: flour, sugar, cocoa powder, baking powder, baking soda, salt, eggs, milk, oil, and vanilla extract.
The quality and freshness of these ingredients significantly impact the final product. Using high-quality cocoa powder will result in a richer chocolate flavor, and using fresh dairy products will give the flan a smoother and creamier texture. Make sure your baking powder and baking soda are not expired for optimal rising action in the chocolate cake.
What kind of pan is best for baking chocoflan?
A bundt pan is generally considered the best pan for baking chocoflan. The shape of the bundt pan allows for even heat distribution and ensures that the cake cooks evenly throughout. It also creates a visually appealing presentation once the cake is inverted, showcasing the distinct layers of chocolate cake and flan.
A tube pan can also be used as a substitute for a bundt pan. Whichever pan you choose, it’s crucial that it is well-greased and floured, or sprayed with baking spray with flour, to prevent the chocoflan from sticking and ensure a clean release after baking. Properly preparing the pan is key to preventing the dessert from falling apart when inverted.
How do I prevent the chocoflan from sticking to the pan?
The key to preventing chocoflan from sticking to the pan lies in thoroughly greasing and flouring the pan before adding the caramel. Use shortening, butter, or baking spray with flour, ensuring that every nook and cranny is covered. Flour helps create a barrier between the dessert and the pan, making it easier to release the cake after baking.
Allowing the chocoflan to cool slightly after baking is also crucial. Let it sit for about 15-20 minutes before attempting to invert it onto a serving plate. This allows the caramel to firm up slightly and the cake to pull away from the sides of the pan, making the inversion process smoother and reducing the risk of sticking.
What is the best way to ensure the flan layer is smooth and creamy?
To achieve a smooth and creamy flan layer, it’s essential to blend the flan ingredients thoroughly until they are completely smooth. Avoid over-mixing, as this can incorporate too much air and affect the texture. Strain the flan mixture through a fine-mesh sieve before pouring it into the pan. This removes any lumps or imperfections, ensuring a silky-smooth final product.
Baking the chocoflan in a water bath (bain-marie) is also critical for achieving a smooth and creamy flan. The water bath provides gentle and even heat, preventing the flan from curdling or developing a rubbery texture. Make sure the water level reaches about halfway up the sides of the pan to ensure proper temperature regulation during baking.
How do I know when the chocoflan is done baking?
Determining when a chocoflan is done baking requires testing both the cake and the flan layers. For the cake, insert a toothpick into the center. If it comes out clean or with a few moist crumbs, the cake is done. Be careful not to overbake the cake, as this can make it dry.
The flan layer should be set but still have a slight jiggle in the center. If it’s completely firm, it may be overbaked. The baking time can vary depending on your oven, so it’s essential to keep a close eye on the chocoflan and adjust the baking time accordingly. The water bath should also be monitored, ensuring the water level doesn’t drop too low.
Can chocoflan be made ahead of time, and how should it be stored?
Yes, chocoflan can be made ahead of time, which is often recommended as it allows the flavors to meld together and the texture to improve. After baking and inverting, allow the chocoflan to cool completely at room temperature. Once cooled, cover it tightly with plastic wrap or place it in an airtight container.
Store the chocoflan in the refrigerator for at least 4 hours, or preferably overnight, before serving. This chilling period allows the flan to set properly and the flavors to develop fully. Chocoflan can be stored in the refrigerator for up to 3-4 days. When serving, let it sit at room temperature for about 15-20 minutes to soften slightly, enhancing the texture and flavor.
