Chocoholic Birthday Cake with Cadbury Twirl

My fiancé is a total chocoholic so for his birthday this month I wanted to make him an awesome chocolate cake. I have a lot of baking books and they pretty much all have chocolate cake recipes - so where to start?

I realised I hadn't baked anything from my Outsider Tart book, Baked in America, for a little while. Outsider Tart is a bakery in Chiswick that is meant to be amazing, though I've never actually been there (even though I live in a different London borough it would take me about an hour and a half to get there - but I'm starting to think it might be worth the trip!). The bakery is run by two Americans who have brought a lot of new techniques to their baking and new ideas to 'bridge the culinary divide'. What they have also done is provide some amazingly decadent, delicious recipes that approach baking in ways that you wouldn't necessarily have thought of.

The cake I made is called "Coke layers" and is on p175 of their book Baked in America. I know that it's possible to reproduce a recipe on a blog, because the original author can copyright the ingredients but not the way they have described the method, but in a way this cake is as much about the method as the ingredients so I wouldn't feel quite right reproducing it without their permission (if I get around to asking and getting permission I will update this post!). After all, have you ever made a chocolate cake using buttermilk, oil, AND butter and 5 eggs.... but more to the point, using marshmallows and Coca-Cola?

I'm going to share with you some of the process I went through. The recipe makes three layers of cake, and half way through adding the ingredients I realised I was going to end up with a LOT of cake -far too much in fact as I was only catering for a meal with my fiancé's parents, not a huge party (that will come next year, when he's 40!).

Starting off by melting butter with the Coca Cola

adding marshmallows and chocolate

Mixing the sugar, oil and vanilla

Here it is after adding the eggs - all 5 of them

Now adding in the cooled chocolate mixture

Two layers about to go in the oven

After baking - three giant layers of cake!

I made a ganache from melted chocolate and sour cream and spread it between two layers

I spread more on top and decorated the top with Twirl Bites

I then decided it needed ganache around the side and more Twirl Bites on top!

I actually ended up with all three layers of the cake baked and decided it was just too big and put one layer in the freezer! I also used self-raising flour rather than plain flour and raising agents, and milk chocolate rather than plain - which would have made the cake sweeter but actually it wasn't an incredibly sweet cake in itself, but the icing was. Mmm, the icing....

I made the chocolate sour cream fudge frosting from the same book to spread in between the layers and on the to, then ran out of sour cream so made a chocolate ganache with double cream which I spread around the sides. I then decorated the top with Cadbury Twirl bites as they were the perfect little chunks of chocolate - slightly unevenly shaped and 'rock' like which appealed to me for this cake.

My fiancé absolutely loved the cake and said it was one of the best I've ever made and I'm inclined to agree. It was light and moist; the cake itself wasn't too sweet but the icing was deliciously decadent.

As I used Twirl on top I'm sharing this with Alphabakes, the blog challenge I co-host with Ros of The More Than Occasional Baker as the letter I've chosen is T.

I'm also sharing this with Love Cake, hosted by Ness at JibberJabberUK. Her chosen ingredient this month is things you can drink, and this cake includes Coca-Cola.
