Gluten Free Chocolate Pistachio Cake With Mascarpone Chocolate Icing

This is one of those cakes that gives a little wow factor and what a lovely birthday cake it makes. You can substitute the sugar for agave syrup and although I really like the addition of the mascarpone icing it does taste great without it as the grated courgette gives it a moist bake. This bake had it’s issues as I managed to get some marks from the wire cooling rack on the top of the cake as I didn’t do what I usually do and add a clean tea towel first! 

Another one of my weekend bakes inspired by the free from bakes on the GBBO and I have been really pleased that the girls in particular liked this bake, as they really don’t like courgette at all. It’s the one vegetable that they both dislike so it was good to bake this without them knowing my secret ingredient, and once they had tasted a slice they were amazed when I let them in on the secret, and even more amazed that they liked it!

To Make The Icing

  • Add the cream and dark chocolate to a small pan and heat gently until all the chocolate has melted and the mixture is smooth.
  • Switch the heat off once at this stage and mix thoroughly, it will be thick and smooth depending on how warm your kitchen is.
  • In a food mixer beat the mascarpone cheese and icing sugar together until smooth and creamy.
  • Slowly add the chocolate ganache to the mascarpone and icing sugar mixture and slowly beat until combined.
  • Once the icing is ready add some of the icing to sandwich the two cakes together, and spread with a palette knife. Sprinkle on the pistachios.
  • Pipe the top of the cake with a star nozzle, you can also pipe around the bottom of the cake to decorate. Finally add some of the reserved pistachios on the top of the cake and  decorate with silver edible balls and serve.

    That looks great! I'm not very good with how things look as I'm a little clumsy but who cares as long as they taste great (apart from Mary Berry)?

    It's so hard to believe this is gluten free – it looks so moist!

      It's a tasty recipe Rebecca and I love that it is packed with courgette to keep it really moist, a great recipe to have if you or someone you know has a gluten intolerance.

    I've never heard of pistachio cake before. Even better, a gluten free one. I bet it tastes divine.
