Ingredients
Here's everything you will need to make this flancocho:
- white granulated sugar
- nonstick spray or butter, to grease the pan
For the Flan:
- evaporated milk
- sweetened condensed milk
- vanilla extract
- eggs
- a pinch of salt
For the Vanilla Cake:
- vanilla cake box mix
- any other ingredients required for the box cake mix
See recipe card for quantities.
Step by Step Instructions
Make the caramel. Pour the sugar into a pan and melt over medium heat. Shake the pan occasionally to make sure the sugar doesn't stick or burn.
Once melted, carefully pour into the bundt pan, moving the pan around to get an even layer at the bottom.
Prep the bundt pan. Preheat the oven to 350° F/ 176° C. Once completely cooled, grease the walls of the bundt pan with butter. Set the pan into a dutch oven or baking dish.
Make the flan batter. In a blender combine all ingredients for the flan and blend until smooth and creamy.
Pour the flan into the bundt pan over the caramel.
Make the vanilla cake batter. In a mixing bowl, make the cake mix according to the directions on the box. Gently pour the batter over the flan batter.
Hint: Make sure to use warm water (it can be from a tea kettle) in your water bath, to jumpstart the baking process.
Bake the flancocho. Add hot water to the baking dish the bundt pan is sitting in. Cover loosely with aluminum foil and carefully transfer to the oven. Bake for 60-90 minutes, or until a toothpick comes out clean from the cake.
Cool, flip & serve. Let the flancocho rest in the water bath for 20 minutes before removing from the water bath and setting aside to cool (this can take up to 2 hours). Carefully loosen the sides of the cake with a knife.
Carefully flip onto a platter.
Serve with the caramel drizzled over top.

Special Tools
To make this recipe you will need a few special tools:
- A blender to make the flan batter - alternatively use a hand mixer or stand mixer
- A bundt pan to bake the flancocho - you can also just use a traditional cake pan if you don't have a bundt
- Nonstick spray or butter to prevent the cake from sticking to the pan
Aside from those, make sure you have a mixing bowl to mix together the vanilla box cake and a pan to make the caramel.
