The Best Chocolate and Beetroot Cake – Our Go-To, Never-Fail Birthday Cake (updated)

Ah, it’s a big day here at Casa Catastrophe.

It’s Dexbox’s 13th birthday, we lose another son to the Teenage Years.

To celebrate and commiserate, here’s the recipe for the cake the twins and I will be baking for him. It’s a chocolate and beetroot cake, rich and indulgent but with veggies too. And super easy, that’s important.

It’s a cake that has stood the test of time in this family.

Beetroot and Chocolate Cake Recipe

  • 3 eggs
  • 450g can of whole baby beetroot
  • 50g cocoa
  • 200g SR flour
  • 200g caster sugar
  • 125g unsalted butter
  • 100g dark chocolate
  1. Heat oven to 180 degrees C.
  2. Drain beetroot and then blend with the eggs until very smooth.
  3. Melt the chocolate and butter together. I gently microwave, but use whatever method you prefer.
  4. Sift flour then mix in with cocoa and sugar.
  5. Mix all ingredients together.
  6. Use one 23cm diameter baking tin or two 20cm baking tins… or make cupcakes.
  7. Baker for 20 – 30 minutes depending on pan or less for cupcakes.


For a really big chocolate cake for birthdays, I often double this quantity and make 2 x 23cm diameter round cakes.

I have been using wholewheat flour when I am making this cake for not so special occasions eg using it to make cupcakes for the kids’ lunchboxes.  You just need to use 10g less flour and let it stand for 10 mins before baking.

But for the birthday cake, I do use white flour and then usually ice with a mix of half dark chocolate, half sour cream, very decadent.

    I googled “best beetroot chocolate cake” and this is where I ended up! It was wonderful. Thank you for sharing the recipe. I noted when I was half way through mixing that you hadn’t included a time for baking. I baked it in a ring tin and it took 45mins
    .No-one could believe there was beetroot in it!

    I’ve always wanted to try a chocolate cake with beetroot, so thanks I’ll try this one when the fancy takes me.

    Two teenagers, what an achievement for both of you.
    Happy Birthday.


    PS Hope you are rocking your new job

    Thanks for sharing, we made muffins, and they were lovely. Quantity was enough for 12, baked for 20mins at 180deg. And no one could tell there was beetroot in them.

      Oh thank you, great to hear this. It’s been my go-to cake for years, I must put up my Thermomix version of the recipe one day. Lovely to hear from you.

  • How did I miss this before? Two of my favourite foods combined – I love beetroot and of course chocolate. I have about 10 chocolate cake recipes for different occasions (quick, healthy, gluten free, divine, brownies etc) and now one more. Thanks! Can’t wait to eat it 🙂

    Wow how many teens in the house now ? Congratulations! this recipe sounds good, once I get my oven up and working I’ll give it a go. I like icing with sour cream – it balances out the sweetness.

    I loved this recipe – made it in to cupcakes. The result was very rich and tasty, but possibly a little dry. I made it using my thermomix. I would love to see your thermomix version – I’m always a little unsure how much to mix cake in the thermo.
