Recipe testing
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.

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 recipe
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.

Cheryl says
I just made this cake does it not rise I thought it would be much higher only about one and a half high is this how it supposed to be.
Jessica Holmes says
Hi Cheryl, yes 1.5 inches per 8-inch layer is about right. It won’t dome too much but be nice and flat and dense like a mud cake should be. If it didn’t rise at all, I would maybe check your baking powder hasn’t expired.
Margaret Mackay says
Hi, could I mix up layers using caramel,chocolate & white choc.
Also if doing a naked wedding cake should I use plain buttercream without the choc ?
Jessica Holmes says
Hi Margaret, excited you are going to try this one. What do you mean by mix up the layers? I also have a great Caramel Mud Cake recipe you might like. I actually love using my favourite White Chocolate Buttercream for naked cakes. But either will work!
Margaret says
Hi Jessica, sorry I just mean’t could I do a layered cake with each cake a different flavour
Jessica Holmes says
Oh absolutely! This cake layers and stacks well.
Jade says
Hi Jess!
Im wanting to make this for hubby’s bday – being that the cake is quite thick (per pan) can I slice the cakes in half to create a 4 layered cake or would it loose its moistness?
Jessica Holmes says
Absolutely! It’s funny you ask that today because I just made it myself and sliced it in half to create four layers. It worked like a dream!
Katie says
The chocolate you add to the cake in the beginning are these chocolate chips, melted chocolate, shaved chocolate, or powder?
Jessica Holmes says
Hi Katie, I use a block of white chocolate. I hope that helps!
Judy Douglas says
I made this cake for my son‘s proposal and I think it was one of the tastiest cakes I ever made and I’ve been cooking and baking for 50 years!
Jessica Holmes says
I love that Judy! How special that you used this cake for your son’s special day!
Gwen says
Hi there!
I have made this recipe a few times now and absolutely love it.
I want to try add a few raspberries to the batter next time- would this work okay?
Thanks so much!
Jessica Holmes says
Hi Gwen, so pleased you enjoyed this one! Yes I’ve done this one with raspberries before – it’s divine. You can use either fresh ones or frozen, but if you use frozen ones don’t thaw them. Just add them to the batter frozen and gently stir so they don’t bleed into the batter. Enjoy!
Karen says
Hi I made this cake and it was delicious.
I wonder how many days will it keep at room temperature?
Many thanks
Karen
Jessica Holmes says
Yay! So glad you enjoyed this one Karen! I find it keeps well for 3-4 days. Otherwise, it freezes REALLY well.
Veronica says
I made this cake for my father in law. It’s exactly as advertised. It’s a cross between a pound cake and a regular layered cake. The cake itself is not too sweet. The buttercream frosting was very smooth. I did add extra milk because it was little thick. Everyone enjoyed this cake.
Jessica Holmes says
That’s so wonderful to hear Veronica! So glad you enjoyed it!
Raiha Fredricsen says
Tried the white chocolate mud cake…for 6 yr old great grandson birthday.
Great success. Recipe is so easy . Will be adding this to my fave recipe book. Much appreciated.
Ollie’s nana Raiha
Jessica Holmes says
This makes me so happy Raiha! So pleased you and your great grandson enjoyed this one!
Miriam says
How early can I make the cake before serving? Can you freeze it or leave it in the fridge for a day or two before decorating and serving?
Jessica Holmes says
Hi Miriam, absolutely! This cake will freeze really well. I highly recommend baking it in advance and freezing it to maximum the freshness. Avoid keeping it in the fridge for days in advance as it’s likely to dry out. Hope you enjoy it!
Harry says
Could this recipe be adapted to a single layer cake?
Jessica Holmes says
Hi Harry, rather than halving the recipe, I recommend following it as is. You can always freeze the extra layer or make a few extra cupcakes! Let me know how you go.
Liz says
Followed recipe correctly twice and both times cake was dense not light soft and moist at all.
Jessica Holmes says
Hi Liz, I’m so sorry to hear that! Did you make any changes to the recipe? This cake is a dense cake since its a ‘mud’ cake. It should be soft and very moist though! If you want to troubleshoot, feel free to email me at jessica@sweetestmenu.com
Kristina says
Do u think this cake would work well being made gluten free
Jessica Holmes says
Hi Kristina, I’m sorry I haven’t tried this cake using gluten free flour. They vary so much I can’t really say without trying it myself. If you do try it, let us know how it goes!
Sandra O'Callaghan says
