  • 200g self-raising flour
  • 2 tbsp very strong coffee (instant is fine)
  • 1 tsp vanilla extract

For the ganache and to decorate

  • 284ml pot double cream
  • 200g dark chocolate (70% cocoa)
  • 50g white chocolate, melted
  • small bag white chocolate Maltesers (optional)


  1. Heat oven to 180C/fan 160C/gas 4. Butter and bottom-line 2 x 20cm sandwich tins. For the cake, break the white and dark chocolate into two small bowls, then melt in the microwave on High for 1 min or over a pan of simmering water. Put everything else, except the coffee and vanilla, into a large bowl, then beat until creamy.

  2. Divide the mixture in two, then add the coffee and melted dark chocolate to one bowl, and the vanilla and melted white chocolate to the other. Stir until mixed through, then tip into the tins. Bake for 20-25 mins until risen and slightly shrunk from the sides of the tins. Cool in the tins for a few mins, then turn onto a wire rack.

  3. For the ganache, heat the cream in a pan, then break the dark chocolate into a large bowl. Once the cream is just boiling, pour it onto the chocolate, then leave for 5 mins. Stir until smooth, then leave until thickened and cool. Split the cakes in two across the middle (a bread knife works well), layer up the pieces, alternating white and dark layers, and sandwiching, then topping them with the ganache.

  4. To decorate, spoon the melted white chocolate into a piping bag with a fine nozzle (or use a sandwich bag and snip off the end instead). Zig-zag the white chocolate over the cake, then finish with a scattering of white Maltesers. Serve on its own or for dessert with pouring cream. Best eaten on the day, but keeps in an airtight container for up to 3 days.

Hi All, I really want to make this cake but in the recipe it refers to vanilla yet this is not in the ingredients listing that I can see.. how much do I need? Can anyone advise?

To all of those that are still debating whether to bake this cake and are chocoholics.......ITS FANTASTIC! Bake it! With the melted chocolate added to the sponge mixture it really makes the sponge extremely moreish......I followed the recipe to the letter and used the chocolate they recommended however, I couldn't find the white maltesers and used 'milkybar white moments' instead...still very nice!!

Thanks Midas that was really helpful. Cool now im ready to rock 'n' roll, will let you know how it went. Im gonna make it on Sat. :-)

For Jooles. No, Jooles you do add water. To make it really strong I just used a tablespoon of instant coffee, added a couple of tablespoons of boiling water to make it dissolve and then measured out a tablespoon of the strong stuff! Hope you enjoy it!

I made this cake for Easter Sunday and although I'm not a huge chocolate fan, my family loved it. I must admit that I didn't have the problem of the cake sinking because it needed longer cooking but I did find that the white chocolate cake cooked more quickly than the dark one so that although the dark one was perfect when it came out the white one was not as light as it had been slightly over cooked. I used different brands of white and dark chocollate and I wonder if this was the reason? The white choc maltezas made a lovely extra touch I thought.

Well after reading everyones comments im defenetly going to make this on Sat. It looks totally yum and really easy to make.
I'll be back to let you all know how it went.

Just one question, i dont want to sound silly, but i take it when you add the coffee it is dry coffee and not addeed to hot water before adding to the cake??
Can anyone help....:-)

I made this and it was delicious, and i baked it for 25 minutes. I found it a very dense cake but the ganache was delicious. I left out the coffee and it still tasted great. Great cake A**

Made this as it looked so fab in the magazine. the receipe was very easy to follow. As I dont like coffee in any shape or form I left this out of the chocolate part of the cake but it still tasted ok. However I wont be making this again for the simple reason that I didnt like it! Neither did my two young sons who demolish 75% + bars of chocolate

Super texture and flavour, everybody loved it!
Have already been asked to make it for a birthday party next week.

With you all there, definately needs longer to cook. (I thought it was my oven!) Very tasty though.

We loved it, but I would agree that it needs longer to bake. Left the second cake in for 30mins which worked well in my oven. Could make this recipe as an adult dessert by sprinking cut layers with Tia Maria...yum!

I would say that the cake needs to be cooked a little longer than 20-25 mins. I checked mine after 20 mins and it was still uncooked in the middle, and then it sunk because Id opened the oven too soon. I have to say it was very tasty once it was cooked but unfortunately didn't look great!
