This is an extremely rich cake which is easy to prepare. The inside is soft and rather creamy. While it is great the first day, we think the flavor improves the second (if you still have any left!). Cooking time does not include cooling time in the oven.
- Pre-heat oven to 180°C.
- Lightly oil (or butter) a non-stick 20 cm springform pan; if yours is not non-stick, butter the bottom, line bottom with parchment paper, then butter the sides and the parchment as well.
- Melt the chocolate and butter in a heat-proof glass bowl over a pot of simmering water, stirring with a wooden spoon until both are completely melted and the mixture is smooth; take the bowl off the heat (and off the pan of water).
- Mix the instant coffee granules and 3 TBS cocoa powder into the chocolate mixture and set aside.
- In a large bowl, beat the eggs and the granulated sugar together for five minutes at high speed, until they are light in color and thickened.
- Grind 30 g of the walnuts in a spice or coffee mill until they become a fine powder.
- Coarsely chop the remaining walnuts.
- Stir the ground walnuts and walnut pieces into the egg mixture.
- Carefully fold the chocolate mixture into the egg mixture until they are completely combined (I like to use a glass bowl so I can see that I've done so).
- Pour the mixture into the prepared pan.
- Bake 40 minutes or until the top of the cake is dry.
- Turn the oven off, leaving the cake undisturbed IN THE OVEN to cool COMPLETELY.
- When the cake is cooled, remove from the oven.
- Remove the cake from the pan, remove parchment paper if used, and sprinkle with the reserved cocoa powder and powdered sugar.
Thank you for this amazing recipe. The minute I placed the cake on the table it was gone!! I used a full cup of walnuts dived as per the recipe. I kept the cake for 2 hours inside the oven to cool. Then I transferred it straight to the fridge for another 2 hours before serving it. It is very rare that you come across a simple recipe like this one, and end up with a delicious result. Thanks again!!!
I just made this cake today and used the advice in the comments and left it for a few hours after cooking. I tasted it and it was extremely rich, very very filling and a tiny slice was enough to fill me. I made this cake because I was extremely intrigued about the fact that this cake had no flour and wanted to see how it would turn out. It was extremely moist and wet and sticky, beautiful. Extremely filling and very naughty! I found the cake extremely easy and quick to make, it does rise a ot so make sure that the tin that you put the mix in has a bit of room at the top. The walnuts really did make the cake fantastic, it would just be goo if there was not a crunchy walnut flavour in there. I also had fun with the cocoa powder and icing sugar garnish on top. Picture will be posted up soon.
This cake is quite good! I took note of the other comments and cut down on the baking time a smidge and then left the oven door ajar to help it cool faster. The meringue on top collapsed a little, which maybe it's not supposed to, but the result was a fudgy, delicious cake! Yum! One other comment is that I think the cake might be better without the walnuts.
