There’s something about chocolate fudge cake that is just perfect, the combination of the rich dark sponge and sweet decadent icing works like a dream. I’ve got plenty of wonderful chocolate cakes on my website, but this one is OH MY GOODNESS AMAZING! You really need to make this one! Whilst being allergy-friendly and vegan you would never know, this cake really is up there with the best!

If you happen to be celebrating the Coronation of King Charles III next weekend, or just having any celebratory occasion coming up, then this cake with certainly be the ‘icing on the cake’!


The sponge is extra dark with lots of cocoa but also has a great bouncy texture and slight tang from the yogurt which really enhances the cocoa flavour. Believe you me, this is no dry crumbly and underwhelming sponge, this is a sponge of dreams, light, fluffy but also robust enough to cope with copious amounts of the beyond delicious icing!

I’m not really sure what makes a chocolate fudge cake, as they rarely contain actual fudge (which would be a bit weird wouldn’t it?) but to my mind the icing on this cake makes the best chocolate fudge cake around. It’s not just a buttercream, but one that is whipped with a LOT of dark chocolate, it’s rich, delicious and difficult to stop eating! Combine the beautiful chocolate sponge with the incredible icing and you really do have the chocolate fudge cake of your dreams. Many a bought chocolate cake delivers more in looks than flavour as they’re often over-sweet, this cake on the other hand balances sweet with dark giving a really well rounded flavour profile. I’m actually going to make the bold claim that here we have a recipe for chocolate cake perfection, that just happens to be dairy-free, egg-free and vegan. Jackpot!

This cake works equally well as a show-stopping layer cake or as a more simple traybake – i’ve given instructions in the recipe on how to make the traybake version. I topped mine with copious amounts of chocolate shavings, but feel free to use any decoration you like.
