White Chocolate Mudcake – any size you need!


Originally given to me by my mother in law, I can’t tell you how much I love this handy recipe! The white chocolate mud cake that results is moist, not too rich and stores well for ages even if you don’t freeze it – though it does freeze very well. Here you’ll find the quantities for almost every kind of cake tin you might need to use, which is just terrific. Finally, the other great thing about this recipe is that it is just a melt and mix cake – no creaming butter and sugar. Even though white chocolate adds to the cost of the cake, the cost of this recipe is still quite reasonable, especially compared to store-bought cakes (and this one is much, much nicer). Today I’m using this versatile recipe for my daughter’s birthday cake – she’s turning 3 tomorrow!

  1. Hi,
    I’m looking to use this recipe for my daughters birthday cake. It’s so great that you’ve given quantities for various sizes tins.
    I just wanted to check that when you say vanilla are you talking about vanilla essence? And that the temperature is in Celsius? Lol!

    Thanks 🙂

  2. Hello, thanks so much for the recipe. I made the 20cm cake today and although it tasted absolutely delicious and the outside lovely and golden, the inside looked raw. I checked with a skewer and it came out clean??!! Should I just have kept it in the oven longer? I know it’s mud cake so should look different to other cakes, but I’m a bit nervous serving it up to people as if I was given it I would think that it wasn’t cooked! Appreciate your advice. Thanks.

    • Hi Pam,

      Thanks for your encouragement. Hard for me to say without being able to see the cake myself. You’re right about the consistency – it’s meant to be firm and moist, without being gooey or wet. Mud cakes, like Brownies, and anything with a large sugar content continue to cook once they come out of the oven, and often once completely cooled, I’m glad I haven’t baked these things for longer. But as long as it isn’t gooey, I would go right ahead and serve it – the eggs will be completely cooked and most people prefer things moist. Hope this helps.
