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!

- **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
- Preheat oven to 350° F (175° C)
- Blend together eggs, milks, vanilla and cream cheese until well mixed.
- In a separate bowl prepare devil’s food cake mix by mixing all the ingredients together until you obtain a smooth batter.
- Pour about 2-3 TBSP of chocolate in the bottom of a baking pan. (You can use some non-stick spray in the pan)
- Pour the flan mix over the chocolate sauce.
- Pour the chocolate batter slowly and evenly over the flan mix (it will go straight to the bottom, but it will raise while baking)
- Place the pan into a larger pan with about ½ cup of water in it to bake in bain Marie or double boiler.
- 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.
- Remove from oven and let it cool.
- 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!

You are quite the creative cook, Ben. This cake sounds and looks really, REALLY delicious. You know, one of those dangerous things that you get up in the night for when no one is looking! And absolutely no calories, of course! YUM.
Ben
Thank you Kelly. I know it is a dangerous thing to have in the fridge, but every once in a while we should indulge ourselves with delicious treats.

This is a might fine slice of Impossible Cake! Great pic, Ben.
Ben
Thank you Cynthia. I didn’t think the picture was going to turn out that pretty. I was experimenting with my camera and some new lighting setting, but it worked!
Lynda
That looks yumm… what would I do if I couldn’t find devils food cake mix? Not an easy thing to find in Egypt.
Ben
Hi Lynda, you could use regular chocolate cake or make your own with cocoa powder. I will post a recipe for a chocolate cake in the future.
How’s life in Egypt?

Did you get a new camera? That’s a GREAT picture. I like it when you make sweet stuff.
So this is a chocolate cake with flan on top? Wow- great idea. I’ve never eaten or made flan, before. I’m putting this on my to-do list.
Ben
Hi Emiline,
No, I haven’t gotten a new camera yet. I am still using my obsolete, yet amazing Minolta film camera. I love that camera and all its functions, the downside is that I have to wait a long time to develop the film.
Let me know when you make it. It is a delicious cake!
Christina
That looks incredible! I can just about imagine biting into the silky flan, then through the fudgy chocolate layer.
Lovely pictures, Ben!
Ben
Hi Christina!
