I love experimenting with recipes that I haven’t tried before. But some recipes I sort of pop in the ‘too hard basket’ and making mud cakes seems to be in that category for me! I have tried lots of cakes that claim to be mud cakes but are really just moist cakes or rich cakes, lovely but not dense mud cakes!
So it is with that in mind that I decided to experiment with white chocolate mud cakes after coming across a stash of white chocolate left over from my Christmas Baking!
This recipe is really really simple, strange but simple and I have found similar recipes in many places online. It results in a lovely dense but moist mud cake that holds that gorgeous white chocolate almost caramelly flavour.
But I have to be honest the winner in the whole deal is definitely the icing – this white chocolate ganache is so easy and just gorgeous! I played around with the quantities to get it just right and it is delicious! So creamy and rich it was worth the experimenting.
Just like normal chocolate ganache it uses just chocolate and cream and is delightful! You leave it to cool in the fridge until it comes to the right consistency for what you are using it for – filling cakes and piping it will need to be left longer but icing cakes it can be still pouring consistency but slightly like peanut butter if that makes sense! Just keep stirring and checking on it until you are happy with it.
Without further ado as I realise you are here for the recipe not my waffling here it is, enjoy & let me know how you get on.
Pin It! White Chocolate Mud cake
On to the recipe!
White Chocolate Mud Cake
Ingredients
- 250 grams White Chocolate
- 250 grams Butter, diced
- 1 1/2 Cups Caster Sugar, 300 grams
- 1 Cup Milk, 250mls
- 1 1/2 Cups Self Raising Flour, 225 grams
- 1 Cups Plain White Flour, 150 grams
- 2 Eggs, Lightly Beaten
- 1 teaspoons Vanilla Essence
- 1/2 teaspoon Salt
White Chocolate Ganache Icing
- 1/2 Cup Cream
- 375 Grams White Chocolate
Instructions
- Preheat Oven to 150 Degrees C
- Prepare a 20 or 22 cm round cake tin - spray liberally with cooking spray and line the bottom and sides with baking paper and spray again.
- In a large saucepan combine the white chocolate, diced butter, sugar & milk and melt over a low to medium heat until the chocolate has melted and the sugar dissolved - approx. 4 minutes
- Remove from the heat and set aside to cool slightly while you prepare the remaining ingredients (approx. 10 minutes to cool)
- Combine the self raising flour and plain flour together in a large bowl with the salt and lightly whisk together.
- In a small bowl combine your eggs & vanilla and whisk them lightly.
- Once chocolate/butter mixture has cooled slightly add the eggs and vanilla and whisk well.
- Add to this the flours and using a whisk quickly beat together all the ingredients until smooth and no lumps remain.
- Pour into the prepared cake tin and bake for an hour and a half or until a skewer or knife comes out with no wet batter, but a few crumbs ok. Take care not to over cook, each oven is different so check at 50 minutes if needed.
- Remove from the oven and allow to sit in the cake tin for at least 25 minutes before turning out onto a wire rack to cool.
- Cake needs to be completely cool before icing, will store well sealed in plastic wrap and then in foil or an airtight container for a number of days until required or freezes well also.
- Mudcakes improve as the days go by, can make ahead up to 3 days in advance or more.
- White Chocolate Ganache
- Microwave your white chocolate pieces in a medium heatsafe bowl for one minute to slightly soften it
- Heat cream in a small saucepan until it begins to simmer
- Once the cream is simmering remove from the heat and pour over the slightly softened white chocolate and let it sit for five minutes
- Whisk gently to combine the cream and white chocolate
- Pour the ganache into a shallow dish to allow it to firm up to the desired consistency, either at room temperature or in the refrigerator.
- Once the ganache is the consistency of thick spreadable peanut butter, stir the ganache to a creamy thick frosting when ready to use
- Spread the ganache all over the cake and smooth
- Store in an airtight container - this will keep at room temperature for a time but best in the fridge if the weather is likely to be warm.
- Enjoy!
And it is as simple as that and absolutely beautiful. This would be such a great cake to use for birthdays, as a special occasion cake or just because! It holds its shape really well and is dense and rich! Perfect for the white chocolate lovers in your life!

This looks like a great recipe is it ok to make in advance and freeze it?
justamumnz says
Yes you can make the cakes ahead of time and then remove from the freezer and ice once they have thawed.
Courtney Black says
Hi there ,
Could you use normal dark chocolate instead of white chocolate? ?
justamumnz says
I haven’t tested this yet sorry. I wonder if the difference in cocoa solids & milk might make a difference. I need to try it soon ☺️
Helen B says
This recipe sounds divine. Do you think I can add raspberries in the mixture ?
justamumnz says
Yes you could, it will change the moisture content so may take a little longer to bake but just keep an eye on it. ☺️
Maria says
Hi Anna, I’ve got a cookie tray 31cm x 22cm (9x12inch) 1.5 inches high and need a sheet cake to be about 1inch high, will the batter of this recipe make two trays of 1inch high approx. Thanks Maria
justamumnz says
Yes it should, just take care with the baking time for such thin cakes. Let me know how you get on.
Vicky says
In regards to the white chocolate mud and, you state “Preheat Oven to 160 Degrees C”. Is that on fan bake, or normal?
justamumnz says
Bake, so normal. Anna 🙂
Vicky says
Thank you. Making it today ??
Nana G says
Hi. I’d like to make this cake in a 26cm round cake tin. How high would the cake be?
justamumnz says
Sorry for the delay in getting back to you, the. She should be at least 3 inches high if not more. I find cakes rise differently due to lots of factors so hard to say exactly. Anna
Annie says
Hello, I would like to cook this in a rectangular brownie tin, how should I adjust the cooking time and temperature?
Thanks
justamumnz says
What size is the brownie pan and what depth? I tend to cook for less time usually any way so in this instance I would check at 40-45 minutes then take 5 minute increments from there ? Let me know how it goes.
Gabby says
Hi there,
Do you use thickened cream in the pottles or just regular cream for the ganache? I’m going to use the recipe for my twins’ 3rd birthday cake this weekend.
justamumnz says
Hi, I use regular cream. Hope it goes well!! Feel free to ask any questions ?
Ros Willcocks says
Thanks Anna for this great recipe, I was looking for a mud cake that only has 2 eggs as my grandson can only tolerate that many in a cake …what a winner, as you say holds it’s shape so well and is very yum… I did use a double layer of baking paper on the bottom and lined the sides with a double layer collar of brown paper to prevent burning …it turned out golden brown … I also added a circle of baking paper on top half way through cooking to prevent top becoming too brown …Thanks Ros
justamumnz says
I’m so pleased you enjoyed this cake Ros!
Kelly says
Just made this for Hubby’s Birthday. My Tiny Humans loved it! I need more practice at making ganache though as mine wouldn’t set enough (even in the fridge for two hours!). Took leftover into kindy and the teachers were very grateful for a Friday treat 🙂
justamumnz says
Hmm might be the ratios, I’ll just have to make it to test it again for you!! So glad you enjoyed it ?
Muffin-top says
Sounds fab, I’m going to give it a try. Did anyone try adding coffee? I also wondered if adding sour cream may help with the dense texture.
justamumnz says
Great ideas!! Coffee would be nice but I’m not a coffee drinker hence no coffee recipes on here lol
Vidu says
Thank u for a great recipe. It came out well. Everybody enjoyed. Thank u!

Made this cake to cheer my other half up after a stressful few weeks at work. Was very well received and beautiful! Serves 24 – more like serves 2 piggies! Thank you!
justamumnz says
Hey Michael, that is awesome! What a nice thing to do 😀 Thanks so much for letting me know – and I agree – 24 serves…….dreaming lol
Lynda says
This sounds great, I realy want to try it! I wonder what it would be like with some coffee added to the hot water?
justamumnz says
Now that’s an idea! I don’t like coffee so never tried but if you do let me know how it goes! 😀

I have been disappointed in the past with mud cakes just like you. Unlike you I haven’t experimented. Thank you for sharing this recipe and for using Dream (my favourite white choc). I will make this for Easter.
