Guest Recipe: Jodi’s Decadent Chocolate Cake + hidden vege

Sharing is caring!

This Decadent Chocolate Cake recipe has been a favourite of our family and friends for birthday celebrations for many years.

I love its simplicity and the addition of beetroot is something I love, it adds another level of flavour!

It makes a big cake so perfect for a crowd or a stash in your freezer!

I’m excited & feeling very privileged to be sharing a recipe for the 10 year celebrations. I hope you love it!

We tested this recipe from Jodi (yes – the original creator of the Creamy Tuscan Chicken Potato Bake & the delicious Whisky Cream Sauce) and thought it was a perfect sweet treat to help celebrate Skinnymixer’s 10 year anniversary!

Honestly, this is one of the nicest chocolate cakes I have ever eaten and can’t wait to make the beetroot version. If you don’t want to add the beetroot and just want a deliciously decadent chocolate cake – this is the recipe for you! 

The beetroot adds another dimension to the chocolate flavour and also some extra hidden vegetables… so really you have no excuse not to eat delicious chocolate cake!

This recipe can be made into cupcakes or as a whole cake and works perfectly with gluten-free flour.

Honestly, this is one of the nicest chocolate cakes I have ever eaten and can’t wait to make the beetroot version. If you don’t want to add the beetroot and just want a deliciously decadent chocolate cake – this is the recipe for you! The beetroot adds a whole new level to the flavour though & reduces the refined sugar further.

  • For an extra dense cake pop the slightly cooled cake into the fridge to completely cool then ice with your favourite ganache.

    Seriously good cake! I made 1 x 6 inch cake (2 x 6 inch cakes) and 1 x 4 inch mini cake. The ganache was used to fill and crumb coat the 6 inch cake and then I decorated with buttercream. The mini cake was filled with buttercream only and decorated. I didn’t use the beetroot version, but I will probably try in the future. Many thanks Jodi for an amazing recipe 🤩

    Halved the recipe and made 12 moist cupcakes! They were delish, better than a coles mudcake. I halved the ganache and added 1/4 cup of icing sugar and a touch of vanilla essence. Absolutely devine!

    The first time with the ganache I found it to be too bitter for my liking. The icing sugar lifted it 😊

  3. I have just made the non beetroot version, I used brown sugar in mine. I didn’t get 24 as I slightly Chubbymixered the quantity in each cupcake wrapper and they look suitably Chubbied as a result 😉
    But omg they are so good.

  4. 5 stars
    These are amazing as cupcakes done in muffin tins. Rich, moist, and delish. I made the beetroot version with gluten-free flour. Absolutely delish hot or cold.

    We had them plain but iced or with whipped cream or ice-cream or custard would all equally

    Jodi, thanks for sharing this amazing recipe. 💗
