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.
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 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 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
- 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
- Cadbury Topdeck Chocolates, for decorating
- 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 and baking powder 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.
