What Is Chocoflan? The Science Behind the 'Impossible Cake'

Known across Mexico as 'Pastel Imposible' (The Impossible Cake), Chocoflan is a culinary marvel where chocolate cake and caramel flan magically switch places during baking.

What Is Chocoflan? The Science Behind the 'Impossible Cake'

The Baking Magic of Density and Steam

When poured into the pan, the dense chocolate batter goes in first, followed by the liquid flan custard. In the oven, the flan sinks to the bottom while the aerated chocolate cake rises to the top!

Two Textures in One Decadent Slice

When inverted, the top layer is silky caramel flan bathed in caramel syrup, resting atop a moist, rich Mexican chocolate cake base.
