Chocolate and Beetroot Cake

Jump to Recipe

A dark, moist earthy cake finished off with a dark chocolate ganache

I had some leftover beetroot from a dinner party and wanted to use it in a cake. My mind initially went to red velvet, but I have honestly never enjoyed the flavour of beetroot in a red velvet cake. I had a chocolate and beetroot cake a long time ago and really enjoyed how the earthy notes of the beetroot complemented the cocoa in the cake – so a chocolate and beetroot cake it was!

The cake is actually really simple to throw together and comes together in one bowl. The cake is not an intensely deep, fudgy chocolate cake as I wanted the beetroot to come through as well. In combination with the dark chocolate ganache however, the depth of chocolate really comes through and adds a lovely silkiness to each bite of the cake.

If you want a chocolate cake with a more dense, fudgy crumb, I suggest this dark chocolate mud cake.


  • Can I substitute the oil in the recipe, with butter? No, the oil here is key to giving the cake a level of moistness. This will not be achieved with butter.
  • What can I substitute for sour cream? If you do not have sour cream, you can use yogurt instead.
  • My ganache split, what should I do? It is likely that the cream was too hot and caused the ganache to split. This may produce an oily feel to the ganache. Heat about two tablespoons of cream, until just hot, but not boiling, and stir it in, until the ganache comes together. This will soften the ganache a bit though, so be mindful of that.
