Introduction

Chocoflan cake, often called the “impossible cake,” is one of the most fascinating and rewarding desserts to make at home. It combines two beloved classics in one pan: a moist chocolate cake and a silky vanilla flan, all topped with glossy caramel. What makes this dessert truly special is the baking process itself. The layers magically switch places in the oven, creating a stunning presentation without any complicated techniques. The first time I made chocoflan, I was genuinely skeptical, but the result was flawless and surprisingly elegant. The rich chocolate base contrasts beautifully with the creamy flan, while the caramel ties everything together with gentle sweetness. This cake is perfect for celebrations, family gatherings, or any occasion where you want to impress without stress. Despite its dramatic appearance, chocoflan is approachable, forgiving, and consistently delivers a dessert that feels both nostalgic and sophisticated.

Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Granulated Sugar
Granulated sugar is used to create the caramel layer. When melted slowly, it develops a deep amber color and a slightly bittersweet flavor that balances the sweetness of the cake and flan.

Eggs
Eggs are essential for both layers. They provide structure to the chocolate cake and give the flan its signature custard-like consistency.

Sweetened Condensed Milk
This ingredient adds richness and sweetness to the flan while contributing to its smooth, creamy texture.

Evaporated Milk
Evaporated milk lightens the flan mixture and helps create a delicate, melt-in-the-mouth finish.

Cream Cheese
Cream cheese adds subtle tang and extra body to the flan, resulting in a richer and more stable custard.

Vanilla Extract
Vanilla extract enhances the flavor of the flan and adds warmth and aroma without overpowering the dessert.

All-Purpose Flour
Flour forms the foundation of the chocolate cake layer, giving it structure while keeping it tender.

Cocoa Powder
Cocoa powder provides deep chocolate flavor and balances the sweetness of the flan and caramel.

Baking Powder
Baking powder ensures the chocolate cake rises properly and remains light despite the custard layer.

Salt
Salt sharpens the chocolate flavor and balances the overall sweetness of the cake.

Butter
Butter adds moisture and richness to the chocolate cake, contributing to a soft, velvety crumb.

Milk
Milk helps create a smooth cake batter and ensures even baking.

Directions

Begin by preheating your oven to 175°C. Prepare a Bundt or deep round pan by setting it aside. In a saucepan over medium heat, melt the granulated sugar until it turns amber. Carefully pour the caramel into the bottom of the pan, tilting to coat evenly.

In a blender, combine the eggs, sweetened condensed milk, evaporated milk, cream cheese, and vanilla extract. Blend until completely smooth and set aside.

In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt. In another bowl, cream the butter with sugar until light, then add eggs and milk, mixing until combined. Gradually incorporate the dry ingredients to form a smooth chocolate batter.

Pour the chocolate batter gently over the caramel layer. Slowly pour the flan mixture over the cake batter. Place the pan in a larger roasting dish and add hot water halfway up the sides to create a water bath. Bake for approximately 60 minutes, or until set. Cool completely before refrigerating for at least four hours. Invert onto a serving plate before serving.
