I know I may have mentioned it once or twice (or a thousand) times before but I am a Birthday cake addict. I'm not fussy either.
It doesn't have to be my Birthday, I just love Birthday cake. I love eating it and oh how I love to make it. Last weekend we celebrated The Twins' mum's Birthday and of course I put my hand up to make the surprise Birthday cake.

Deciding on the type of cake wasn't difficult - she loves white chocolate mud cake but I didn't want to do a plain white chocolate ganache. I don't know about you but I find it overly sweet and this cake is sweet enough.
For some reason my brain always turns to raspberries when I need something to cut the sweetness. It also helped that they'd add a lovely natural pink - the Birthday girl's favourite colour.

I wanted to do a double layer so there'd be a nice surprise icing spread between the two cakes when she cut into them so I was going to double the recipe.
That's when I saw there was 350g of butter in one cake. IN ONE CAKE! Yes this was going to be tasty. Instead I trusted my instinct and made one batch knowing I could make another if it didn't spread between the two tins. Let me tell you, one batch was plenty.
If you only want a small cake I'd even advise halving the recipe although dividing 3 eggs in half may prove tricky. Maybe you could divide it by 3?

The original recipe advises you not to discard the trimmings when you even out the top of the cake. It actually tells you to eat them because they're tasty. Well who am I to not follow instructions?
I may have gone to bed with a bit of a sore belly on Friday night. Don't make this cake alone if you have weak self control. It's really really moreish.
Sorry about the inside shot. I forgot to take my camera to the party and these were some terrible snaps with my phone while trying to stay out of the way of the cake eaters.

The pretty and girly theme sort of came out of nowhere when I started randomly decorating before bed on Friday night.
I slightly regretted making the pearl trim when I got what I thought had to be nearly all the way around and realised I was about a quarter done. It does look rather nice though so remind yourself of that if you decide to copy mine and start to curse me.
I made the little flowers with an 8-point fat star tip and added some sugar pearls to the middle of each one. I've also done bigger versions with a Malteaser in the middle (yum!).
I absolutely loved this cake and I'm not even a big white chocolate fan. To me it's really more like a white mud-cake or a chocolate mud cake for people who can't have chocolate. Enjoy!
What about you? Do you like making or eating Birthday cakes or both?

Recipe

White chocolate mud cake with raspberry buttercream
Ingredients
Cake
- 180 g 6.3oz white chocolate, chopped
- 350 g 12.3oz unsalted butter, softened
- 2 ⅔ cups caster superfine sugar
- 1 ½ cups milk
- 2 cups plain flour
- ⅔ cups self raising flour
- 1 teaspoon vanilla extract
- 3 free-range eggs slightly beaten
Icing
- 4 tablespoon butter softened
- 100 g 3.5oz raspberries, fresh or frozen and thawed
- 4 cups icing confectioner's sugar
- A few tablespoon milk
Instructions
- Pre-heat the oven to 140C (310F) fan-forced and grease and line two round 20cm cake tins.
- In a large saucepan, combine the white chocolate, butter, sugar and milk and stir over medium heat until smooth.
- Transfer the mixture to a large bowl and set aside to cool for at least 15 minutes.
- In another bowl, sift the flours together and in a separate bowl, lightly whisk the eggs and vanilla.
- Alternate between the flours and the eggs and whisk them into the chocolate mixture, half at a time. Whisk just until everything is incorporated.
- Divide the batter evenly between the two tins and bake for 1h 45m or until a cake tester inserted in the middle comes out clean.
- Leave the cakes to rest in the tins for 5 minutes before turning out onto a wire rack to cool completely.
- In the bowl of an electric mixer, beat the butter until light and creamy.
- Add the raspberries and beat until smooth.
- Slowly add the icing sugar beating until it is all mixed in.
- Add a little milk to get it to a spreadable consistency and then beat for 2-3 minutes or until fluffy.
- Slice the top off one of the cakes to flatten it out and place, bottom down, onto a serving plate.
- Ice the cut side of the cake.
- Trim the other cake then place it cut-side-down on top of the first cake.
- Ice the cakes completely then decorate as you wish.

Sorry Claire, I ment to say is there a certain height that the tin is supposed to be?
Thankyou!
Claire says
Oh sorry Ebony! My tins are about 6-7cm deep
Ebony says
Hey Claire,
I couldn't find what size tin you used for the two cakes so I was just wondering if you were able to let me know?
Thank you!
Claire says
Not a problem Ebony - they were 20cm round tins.
milena says
Hi Claire,
Im looking to make this cake at least one or even two layers higher. Do you think i will need to add additional support to hold it up? As you mentioned, it is quite generous.
thanks so much! xx
Claire says
Hi Milena. It's probably a good idea to add some re-inforcement to make sure it doesn't collapse. You can do this easily with straws with skewers in them and then a cake board on top then the next layer. Good luck!
Arielle says
Hi Claire!
This is such a great recipe and perfect for my best friends birthday who loves both these key ingredients! Do you know relatively how tall/high the cake is? I am hoping it will fit into a container I have, in order for me to be able to transport it! Thanks!
Claire says
Hi Arielle. I think it is about 10cm tall. You can make it in a bigger tin and just do one layer if you prefer? Or another option would be to ice it when you get there? I hope it works out and your friend loves it!
Debbie O'kane says
Do you know if this cake is dense enough to hold up under fondant? Thanks In advance!
Claire says
Hi Debbie. Yes it should be fine under fondant.

Claire says
I thought so Stephanie!
Jess says
Oh my - that is one very pretty cake, friend! I have absolutely no self control with baked sweets, and an invitation to nibble on the pieces...well, it would be all over for me.
Claire says
I need to find some baking buddies so I don't eat it all myself!
Hotly Spiced says
The cake looks very pretty. Such a lovely colour. I bet your friend was overjoyed. Good on you for putting up your hand to make the cake xx

Claire says
Thanks Tania!
Lorraine @ Not Quite Nigella says
Aww what a pretty shade of pink! And yep fellow birthday cake addict here too. In fact I'm waiting for someone to have a birthday so that I can bake a cake! *taps feet impatiently*
Claire says
Didn't the raspberries make a nice colour? Maybe we should start celebrating half Birthdays?
The Life of Clare says
This cake looks amazing! I also love cake! All kinds! However it was J's birthday this week and I failed in my foodie wife duties and didn't even think to make a cake!
Claire says
I know what you mean Clare. Will's not a big cake eater so he's not really fussed if I make a Birthday cake or not!
Maureen | Orgasmic Chef says
I love the idea of cake but when I eat it I think, "why did I make so MUCH cake?" John doesn't eat cake so it's always up to me. :)
Your cake is really pretty, Claire!
Claire says
Me too Maureen! Will doesn't really eat cake either. It's dangerous!
