This soft and tender White Chocolate Mud Cake is perfect for your next party or celebration. Two layers of white chocolate mud cake covered in creamy white chocolate buttercream.
I’m on a mud cake bender.
My latest obsession? This White Chocolate Mud Cake 👇🏻 Two layers of buttery mud cake covered in luscious white chocolate buttercream and topped with clouds of chocolate frosting.
Big, buttery and oh-so-irresistible.
First there was my Chocolate Mud Cake. Then my Caramel Mud Cake. And now my favourite White Chocolate Mud Cake.
All I know is when you put chocolate in your cake batter, it transforms into one rich, buttery cake with a truly enviable texture. And when you add White Chocolate Frosting that’s also made with real chocolate, well then you are in chocolate heaven.
While I’m usually partial to one layer cakes, some celebrations call for something special. And that’s when a layer cake like this White Chocolate Mud Cake is just perfect.
Two layers of cake covered in white chocolate buttercream with clouds of chocolate frosting piped on top, with squares of chocolate in between.
This White Chocolate Mud Cake recipe is so easy to make, in fact, you don’t even need an electric mixer. It can be baking away in the oven within 30 minutes.
All you need to do is mix together butter, white chocolate, sugar and milk on the stove until smooth and creamy. Then it’s time to add the remaining ingredients. A quick stir and then it’s time to bake.
What you’ll end up with is a soft and tender cake. One that’s moist and buttery and tastes like deliciously smooth white chocolate. But what sends the cake over the top is the frosting.
Just like my Caramel Mud Cake, I used white chocolate buttercream. I’ve long been a fan of adding real chocolate to my buttercream, but I only recently tried adding white chocolate. And let’s just say, I’ve been putting it on e-v-e-r-y-t-h-i-n-g ever since.
It’s also the perfect frosting for decorating a layer cake – smooth and creamy and really easy to work with. You could stop there, but for a little something extra, whip up a small batch of chocolate buttercream.
Then add your favourite chocolates on top. What you’ll end up with is a buttery mud cake made with real white chocolate, a creamy frosting also made with white chocolate and a little real chocolate buttercream sitting alongside pieces of your favourite chocolate.
ALL. THE. CHOCOLATE. THINGS.

White Chocolate Mud Cake
A delicious two layer White Chocolate Cake covered in white chocolate buttercream.
Ingredients
White chocolate mud cake
- 230 grams (1 cup / 2 sticks) unsalted butter, roughly chopped
- 300 grams (2 cups) good quality white chocolate
- 200 grams (1 cup) caster sugar or granulated sugar
- 240 ml (1 cup) full fat or whole milk
- 2 large eggs
- 2 teaspoons vanilla extract
- 350 grams (2 and 1/2 cups) plain flour or all purpose flour
- 2 teaspoons baking powder
- 1/4 teaspoon salt
White chocolate buttercream
- 230 grams (1 cup / 2 sticks) butter, room temperature
- 150 grams (1 cup) good quality white chocolate, broken into pieces
- 1 teaspoon vanilla extract
- 435 grams (3 and 1/2 cups) icing sugar or powdered sugar
- 2 tablespoons whole or full fat milk
Chocolate buttercream
- 115 grams (1/2 cup or 1 stick) butter, room temperature
- 100 grams (2/3 cups) dark chocolate, broken into pieces
- 250 grams (2 cups) icing sugar or powdered sugar
- 2 tablespoons full fat or whole milk, room temperature
- Cadbury Topdeck Chocolates, for decorating
Instructions
- Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Grease and line two 8-inch round cake pans with baking or parchment paper.
- In a medium saucepan, add butter, white chocolate, sugar and milk. Place on medium heat, stirring until smooth and sugar has dissolved. Set aside for a few minutes to cool slightly.
- Add eggs and vanilla to cooled white chocolate mixture and stir until combined. Add flour, baking powder and salt and stir until combined – don’t worry if the batter is a little lumpy.
- Divide the cake batter between the two cake pans and place in the oven for approximately 30-35 minutes or until a skewer inserted in the middle comes out clean. Transfer to a wire rack to cool completely.
- To make the white chocolate frosting, place butter in a large mixing bowl and beat with an electric mixer on medium speed until pale and creamy. Meanwhile melt the chocolate in a microwave, stirring in between 20 second bursts, until just melted and set aside.
- Add vanilla, half the sugar and one tablespoon of milk to the butter and beat until combined. Add the remaining sugar and beat until smooth.
- Add melted chocolate, ensuring the chocolate is still smooth and melted but is not warm. Beat until the chocolate is completely mixed through. If frosting is too thick, add an extra tablespoon of milk.
- Place one cake layer onto a cake board or stand. Cover the top with white chocolate buttercream. Place second cake layer on top (upside down for a nice flat top). Frost the top and sides of cake. Smooth sides using a cake scraper.
- To make the chocolate frosting, place butter in a large mixing bowl and beat with an electric mixer on medium speed until pale and creamy. Meanwhile melt the chocolate in a microwave, stirring in between 20 second bursts, until just melted and set aside.
- Add half the sugar and one tablespoon of milk to the butter and beat until combined. Add remaining sugar and beat until smooth. Add melted chocolate and beat to combine. Add an extra tablespoon of milk if needed.
- Add chocolate frosting to a piping bag fitted with a large round tip and pipe frosting around the edge of the cake. Decorate with chocolate pieces.
Eleanor says
How far in advance can this cake be made. I’m baking Thursday for Sunday. Am I better freezing or will it store ok wrapped and in airtight container?
Jessica Holmes says
Hi Eleanor, I recommend freezing it to maximise freshness. I hope you love it!
Sara says
Hi there. I want to make this cake tomorrow – was wondering if 8inch cake tins that are 4cm deep be ok? Or will it like overflow ? Thank you
Jessica Holmes says
Yes they should be fine Sara!
Elisha says
Hi Jess,
I’m excited to try out this receipe for my daughters rainbow birthday cake ( Ive actually never made a mud cake before) . My question is can I make the layers a few days in advance and freeze them to decorate the day before the party or will this ruin the texture of the cake?
Thanks
Jessica Holmes says
Hi Elisha, excited you are going to make this cake! Yes you can freeze it – it keeps quite well.
Emma says
Hi Jess,
If you only have 1 cake tin, could you bake all together a little longer? I have a deep cake tin. Also could you add raspberries to it?
Thanks 🙂
Jessica Holmes says
Hi Emma, one of the problems of using one 8-inch cake pan is that the cake will take much longer to cook. Because of the sugar and white chocolate in this cake, it browns quite quickly so it’s likely the outside would overcook before the inside was completely baked through. You could use a quarter sheet pan to make one layer. Or you could use your one cake pan and then cook the remaining batter as cupcakes?
Heidi says
Do you also have a chocolate mud cake recipe like this white one or shall I just reduce the amount of flour and add cocoa powder instead please?? X
Jessica Holmes says
Hi Heidi, I do have a Chocolate Mud Cake recipe!
Heidi says
Can both of these cakes be made in a sheet cake pan (approx 9x13inches) as I’d like to try doing a number cake and posts I’ve seen on instragram say mud cakes are more stable for using when cutting out numbers from a template xx
Jessica Holmes says
Absolutely! But this recipe would only make one quarter sheet pan cake (9 by 13 inches).
Shirley says
Hi, could i put a layer of strawberry jam in the middle of the cake along with the white chocolate butter cream, or would this make it to sickly?
Jessica Holmes says
I think that would be lovely Shirley! And if you are worried, you can reduce the icing sugar in the white chocolate buttercream to 375 grams (3 cups).
Saarah says
Amazing recipe, thank you! Cooked it for a few minutes less than suggested so I recommend checking it after 25 mins.
Jessica Holmes says
Great, thanks for the feedback!
Sharon Chawner says
Found this recipe easy to use, However my cake when cutting, is a little crumbly.
I checked in on my cake and found 45 minutes to be cooked. I used 16 inch round tin.
Any suggestions to avoid being crumbly?
Jessica Holmes says
Hi Sharon, if it was crumbly, it sounds like it was a bit overbaked. I would take it out a little bit earlier next time and I’m sure that’ll make a difference.
Tina says
Hi Jess
I’m wondering…how tall does this cake stand? I have 4inch high pans and love the height. Will I need to increase the recipe to achieve that do you think?
Jessica Holmes says
Hi Tina, oh I think this one is about two inches deep.
Grace says
Hi Jess, would I be able to use this recipe for cupcakes? If so, what would I adjust the cooking time to be, if using standard 12-hole cupcake trays? Thank you!
Jessica Holmes says
Yes absolutely Grace! Typically, a cupcake would take around 16-18 minutes. You’ll know they are ready when they spring back lightly to the tough and/or a skewer inserted into the middle comes out clean. Alternatively, you could try my Caramel Cupcakes which are similar (and delicious).
Anna says
Hi Jess,
My partner’s birthday is tomorrow and this recipe is everything he loves!! I cannot wait to make this for him but I wanted to know if it would be better to be made fresh on the day it will be eaten (tomorrow) or if it is okay to make it 1 day in advance and store in the fridge over night ? Would there be a noticeable difference in the taste and/or texture of the cake after it has been refrigerated?
Thank you in advance 🙂
Jessica Holmes says
Hi Anna, I’m excited you’re going to try this cake! It can definitely be made a day in advance. However, I try to avoid putting my cakes in the fridge as they can dry out. I recommend wrapping them in plastic wrap once they are completely cooled and storing them in an airtight container at room temperature. Then frost them on the day of serving. I hope that helps!
Teesha says
Hi, i love love love your recipe, i made it and the whole cake was gobbled up within they day ha!
My question now is, can i colour the batter been that it has white chocolate in it? i want to make a rainbow layer cake for my daughters birthday using your recipe 🙂 Thanks!
Jessica Holmes says
Hi Teesha, I’m so glad you loved the cake! Yes colouring the cake batter should be fine. I do highly recommend using good quality food gels rather than food colouring (they are too watery). Also try not to over-mix the cake batter when adding the colours.
Polly says
All other white chocolate cakes I have made in the past do not compare to this cake. It is absolutely spot on with the flavour of white chocolate coming through really nicely. A really delicious cake that I will be making again!!
★★★★★
Jessica Holmes says
I’m so happy to hear that Polly! Thank you for the lovely feedback.
Ruby says
Hi
Would you have a recipe for a same cake but for 25cm round pan?
Or could this same recipe be used for a 25cm round pan since you’ve used two 8inch pans
Thank you
Jessica Holmes says
Hi Ruby, this article will help you convert recipes to different pan sizes.
Tracy Stojanovski says
Hi, this recipe sounds yummy 😊
My is can this recipe be doubled need to make 9 13 inch sheet cake.
Can’t wait to start making😊
Jessica Holmes says
Hi! You can make this recipe as is and use it to make one 9 by 13 inch cake. Hope you enjoy it!
Heidi says
Can this recipe be used to make a number cake if I put the cake mixture into a sheet cake tray. I’ve some number templates I’m desperate to try but want a recipe that will work to cut the number out from x
Jessica Holmes says
Hi Heidi, yes! You could use this recipe to make one 9 by 13 inch sheet cake.
