White Chocolate Mud Cake with Whipped White Chocolate Ganache
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.

White Chocolate Mud Cake
- 115g butter
- 150g white chocolate
- 100g sugar
- 130ml milk
- 1 large egg
- 1 teaspoon vanilla extract
- 175g spelt flour (see notes)
- 1 teaspoon baking powder
- 150g white chocolate
- 75ml milk
- 30g butter
- 20g icing sugar
- White chocolate shavings
- Chocolate seashells (use anything)
- Pre-heat the oven to 175°C and line/grease a 6" (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 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.
- 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. Slice and enjoy!
- I use metric measurements in my recipes. If you prefer imperial (cup) measurements, Cook it Simply offer a handy conversion tool.
- You can use plain (all purpose flour) if you prefer. Just reduce the amount of milk used by 10ml.
