Mission: Impossible Cake

How do they make it? That was the first question that popped in my mind the first time I had a piece of the so-called Pastel Imposible (Impossible Cake). I love flan and I love chocolate in any form. Chocolate flan was just an idea back then, but a flan and a chocolate cake baking together and yet not mixing together was something that really seemed like an impossible thing to do, a very tasty dream.

I did what I always do when I have a culinary blockade. I called my mom. It turned out that the impossible task was not so impossible after all. It actually was a very easy recipe that has become one of my favorites since. Ladies and gentleman, the only, the original, the Impossible Cake!

Mission: Impossible Cake
Recipe type: Dessert
Cuisine: Mexican
Serves: 8-10
  • **For the Flan
  • •4 eggs
  • •1 can sweet condensed milk
  • •1 can evaporated milk
  • •1 tbsp vanilla extract
  • •4 oz. (100gr) cream cheese
  • •chocolate sauce
  • **For the Chocolate Cake:
  • •1 cup devil’s food cake mix
  • •½ cup vegetable oil
  • •½ cup milk
  • •1 egg
  1. Preheat oven to 350° F (175° C)
  2. Blend together eggs, milks, vanilla and cream cheese until well mixed.
  3. In a separate bowl prepare devil’s food cake mix by mixing all the ingredients together until you obtain a smooth batter.
  4. Pour about 2-3 TBSP of chocolate in the bottom of a baking pan. (You can use some non-stick spray in the pan)
  5. Pour the flan mix over the chocolate sauce.
  6. Pour the chocolate batter slowly and evenly over the flan mix (it will go straight to the bottom, but it will raise while baking)
  7. Place the pan into a larger pan with about ½ cup of water in it to bake in bain Marie or double boiler.
  8. Cover with foil and bake for about 1 hour. The chocolate cake will move to the top and you can check readiness with a knife or toothpick.
  9. Remove from oven and let it cool.
  10. Refrigerate for at least 2 hours before inverting the cake over a cake dish. The chocolate sauce will flow over the cake.

As you can see this Impossible Cake is not as tough as its names suggests. I like to use chocolate sauce for this particular flan, but you can use caramel as the original recipe calls for. I also like to make it Neapolitan flan (cheese flan) instead of just the egg custard. So this is a tree-recipe cake in one, if you look at it that way, a flan, a chocolate cake and a not so impossible cake.

Buen provecho!
