So at a friend's dinner party a month ago, my friend made a chocolate and salted caramel cake from the hummingbird bakery cook book and it was amazing!! So this weekend it was my brothers birthday and we had some friend's staying so I thought I'd give it a try as well!
The recipe is for a huge three tier chocolate cake, with chocolate icing and salted caramel sandwiched between the layers of cake. My friend had previously made the full three tiers but I decided I would use two tiers for a birthday cake and have the last single tier as dessert with friends.
The first part of the process is to make the salted caramel, this was slightly different to the salted caramel ice cream I'd made over the summer but I weighed out my sugar, some golden syrup and some water in a pan. I'm really scared of burning the sugar and also really scared of it crystallising. The method I use is: I swirl the water at the beginning to make sure that it gets all of the sugar wet and there are no dry sugar clumps and I make sure the pan is super clean to start with. I also make no attempt to stir it at any point, apparently you can stir it before the sugar has completely dissolved but I'm always really scared that this will cause the sugar to just clump together so I just stand close guard over the pan and if it looks like the sugar is not melting consistently I swirl the pan. The recipe suggests you boil the sugar for 10 minutes, but does not state the temperature you should heat it too and I do have a sugar thermometer so I stuck that in but I was quite nervous about burning the caramel and also about getting it all the way up to this temperature so I don't think I quite cooked it for the right length of time or to quite the right heat. But it wasn't burnt which was the main thing! You then need to heat the cream and the salt and then pour this into the caramel, off the heat. This bubbled up lots and luckily I poured the cream quite slowly otherwise I think there would have been a lot of mess over my cooker hob. I would definitely recommend you use a high sided pan to cook the caramel in initially as it came pretty close to overflowing! You then just stir this and pour it into a small bowl to cool. Mine was quite runny in the end, although it did thicken as it cooled, but I wonder if I had cooked it for a bit longer and slightly hotter if it would have thickened up a bit more...here is the caramel just cooling in a bowl!
Then on to the chocolate icing, this also needs a caramel base to start with, so I washed up my two pans and went through the same process again without the salt! This time I didn't bother with the thermometer and just timed it for the 10 minutes but had turned down the heat a little. You then pour in the cream again and then leave this to cool for a minute before pouring it over the chocolate! There is so much chocolate in the recipe 450g followed by a whole pack of butter (and a bit more) which does not sound healthy at all, but it tastes AMAZING! So you stir the chocolate and caramel mixture until it is well mixed then you use an electric mixer to mix it for about 10 minutes until the mixture is cool, before adding the butter. I thought I hadn't let this get cool enough as when I added in the butter it started to melt and was gone before I knew it, and the recipe then says to mix this until it is whipped then put it in the fridge to cool for 40-50 minutes. My mixture was pretty liquid so I thought it had all gone horribly wrong and I had no idea how I would be able to ice the cake with liquid... so with little confidence I whisked it for a minute or two then poured it into another bowl and whacked it in the fridge. Here is the frosting just before it went into the fridge.
On to the easy part, the sponge. I mixed together all of the dry ingredients with the butter then added the eggs and buttermilk mix. Split the mixture into three lined sandwich tins and whacked it in the oven. DONE! I let the cakes cool down a bit then took them out of the tins and left them on a wire rack.
Now on to assembling the cake. I took out my cooled frosting from the fridge, and I was so surprised. It had completely set and was solid but easily spread over the cake. Like the consistency of Nutella!
I got my first layer of cake, then spread three tables of the salted caramel mixture over the top followed by the frosting then sandwiched on the second layer. Here is a picture of just the salted caramel before the rest of the frosting. As you can see the caramel is quite runny and could do with being slightly thicker...
I then covered the cake in the frosting, as an aside there is loads of spare frosting that I just ended up throwing in the bin as I didn't know what to do with it, and thats even after I iced the single tier cake as well. I also added lots more of the salted caramel to the single tier as there was lots left and this was really nice. I think it does need quite a lot of salted caramel, as the salt adds a really nice dimension to the sweet cake.
Here is a final picture of the cake with a few salt flakes dusted over the top:
And here is a picture of the structure of the cake after we all had a slice!
