Flourless Citrus Chocolate Cake Thermomix Conversion (Thanks Nigella!)

  • Author: The 4 Blades

  • Yield: 6-8


Bec first came across this recipe when her sister-in-law made it for a family get together. It was love at first bite. While Bec avoids dairy, she tolerates pure butter OK so this cake is Bec-friendly if dairy / soy free chocolate is used. That’s why we used the Lindt 85% dark chocolate. It has become one of Bec’s favourite chocolate cake Thermomix recipes.

In fact, she loves it so much that it was featured in Episode 53 of the podcast – Bec’s Best Birthday Thermomix Cake Recipes.

The original recipe is called ‘Chocolate Lime Cake’, but after a lot of testing to get this conversion just right for you, we know that you can get creative and use any kind of citrus. Using half an orange is just delicious for those Jaffa-lovers out there!

This chocolate cake has a tendency to burn on top (and it will very likely crack by the end of cooking) so be sure to follow the steps listed in the recipe to minimise the chance of this.
