Yum. White chocolate mud cake. Yum, indeed.
Before making this cake, I’d heard of mud cake but never white chocolate. Scrolling through Pinterest, a recipe from one of my favourite blogging bakers, Jess from The Sweetest Menu popped up. A layered white chocolate mud cake. It looked good and simple. It had to be mine. And it was.
Before trying my cake, I’d wondered how different a mud cake would be from a regular sponge. It didn’t appear that different. Oh, but it was. The sponge was very dense but at the same time, really soft. It was delicious. I changed very little from the original recipe, but added a touch more milk to compensate for the spelt flour. I also decided to make only one cake rather than layer it.
The frosting is my own and came about as a freak accident. I wanted a white chocolate ganache but on going to the fridge to fetch my cream found I didn’t have any. It was a Saturday afternoon with me in my comfy clothes and I didn’t want to leave the house. Faced with the dilemma of either changing my plans (with the control freak that is myself screaming loudly against that idea) or adapting to what I had, I went with making ganache using milk and butter.
I Googled the possibility of doing this and several dark chocolate recipes popped up. Nothing for white chocolate, though. Feeling brave and undeterred (and still not wanting to leave the house), I tried it. It worked but didn’t set very thickly (or perhaps I was a little impatient). So, next idea: let’s whip up that ganache. Success! It was really lovely and went amazingly well with my white chocolate mud cake.
I didn’t pipe the frosting. Hello! This is me, remember. But I swirled it a little. And topped it with Guylian’s chocolate seashells (just because I felt like it) and white chocolate shavings. Third day in, the cake was softer and tastier than the day it was made. All in all, a total winner.

Instructions
Cake:
- Pre-heat the oven to 175°C (350℉) and line/grease a 7" (18cm) springform pan.
- Add the butter, chocolate, sugar and milk to a pan and heat until the chocolate and butter have just melted and the sugar has dissolved. Put to one side to cool for a short while.
- Add the egg and vanilla and mix just until combined. Add the flour and baking powder and stir until everything is combined (don't over mix).
- Pour into the prepared pan and bake for around 40-45 minutes (in the lower part of the oven) until an inserted skewer comes out clean.
- Allow to cool for around 10 minutes, then remove the pan and allow to cool on a wire rack until it is completely cold.
Frosting:
- Chop or break the chocolate into small pieces and place in a fairly deep bowl.
- Melt the butter and milk together until the butter is melted and it starts to bubble slightly at the edges.
- Pour the milk/butter mixture over the chocolate (making sure all of the chocolate bits are covered) and leave for five minutes.
- Whisk quickly, until everything comes together and you're left with a thick mixture.
- Place in the fridge for a couple of hours to thicken.
- Add around 20g of icing sugar to the chocolate mixture and whip/whisk until a thick frosting forms.
- Spread all over the cake and top with whatever decoration you fancy.
- To make chocolate shavings chill a block of white chocolate and scrape down it with a knife. Decorate with whatever you fancy (or leave as it is). Slice and enjoy!
