Preheat oven to 180°C (350°F) and grease a 9-inch bundt pan.
Caramel Layer: Melt sugar in a non-stick pot over medium heat, stirring until it becomes a deep amber color. Pour into bundt pan to set.
Flan Layer: Blend eggs, cream cheese, condensed milk, evaporated milk, vanilla, and salt until smooth. Sieve the mixture and pour over the caramel layer in the bundt pan.
First Bake: Cover the pan with foil, place in a roasting pan with boiling water halfway up the sides, and bake for 45 minutes.
Cake Layer: Mix cocoa powder with hot water, then add oil, yogurt, and eggs. In a separate bowl, mix flour and sugars, then combine with the wet ingredients until smooth.
Second Bake: Pour cake batter over the flan, re-cover with foil, and bake for 1 hour 20 minutes to 1 hour 30 minutes, removing foil after 1 hour.
Cool and Chill: Let the chocoflan cool slightly, then refrigerate for at least 3 hours (overnight is best).
Remove from pan, slice, and enjoy!
