Thermomix White Chocolate Mud Cake

This Thermomix White Chocolate Mud Cake with white chocolate buttercream is rich, decadent and delicious. Perfect for parties... or just because.

I often make a Thermomix chocolate cake for birthday cakes, but my daughter has been nagging me to make a white chocolate mud cake for ages, so I set about experimenting for her.

This is the result - a truly rich, super moist and indulgent cake that you are going to love!

Even if you are not a fan of white chocolate (like me) I am sure you are going to love this cake. I have had countless people say "I don't even like white chocolate but this is amazing!"

The white chocolate flavour in the cake itself is subtle, while the white chocolate buttercream packs a punch of flavour... it is rich, sweet and oh so irresistible.

Ingredients for the cake

Aside from the white chocolate, you should already have everything for this white chocolate cake in your pantry/fridge. You will need:

How to make the cake

Full instructions are located in the recipe card at the bottom of this post.

First make sure you have pre-heated the oven and greased and lined your cake tins. I use two 8-inch (20cm) tins.

To make the cake, start by grating the chocolate in the Thermomix. Then add the milk, butter and sugar and heat it all for 4 minutes, until the chocolate is melted and the mixture is smooth.

Next mix in the eggs and vanilla extract. And then finally add the flour and baking powder and mix.

Now pour it into your prepared cake tins and bake for around 30-35 minutes, until a skewer inserted in the middle comes away clean.

Allow to cool on a wire rack completely before adding the buttercream icing.

White Chocolate Buttercream

While the white chocolate flavour in the actual cake is pretty subtle, you get the full white chocolate hit with this decadent and indulgent buttercream.

Yes, it's a little sinful but it is soooo delicious 🙂

You will need:

• White chocolate - good quality eating chocolate is best, but I have also made this with baking white chocolate.
• Icing sugar
• Butter - cold, straight from the fridge works best
• Milk
• Vanilla extract

To make the buttercream, start by grating and melting the white chocolate. Now set it aside to cool to room temperature while you clean and dry the bowl.

(I find by the time I run the pre-clean mode on my TM6 then rinse and dry the bowl, it is at the right temperature.)

Next, blitz the icing sugar for 10 seconds on speed 9 to make sure it is well sifted, and set aside.

Then, whip up the butter for 30 seconds on speed 5 before adding in the sugar, milk and vanilla extract and mixing for a further 30 seconds.

Finally, set the Thermomix mixing and slowly pour the melted chocolate through the hole in the lid to mix it all together.
