Chocolate courgette cake
Use up a glut of courgettes in this decadent, chocolaty cake that serves up to 12 – great for a birthday or other celebration
Put the pistachios into a food processor and pulse to a fine powder - don´t over-blend as you don´t want to release the oils, it should still look dry. Line a 20cm x 25cm cake tin with baking paper. Heat the oven to 200C/180C fan/gas 6.
Beat together the butter and sugar with an electric whisk until pale and creamy. Add the eggs, one at a time, then briefly mix in the ground pistachios, flour, baking powder, yogurt, courgette and lime zest to make a thick batter. Scrape into the tin, smooth over the top and bake in the middle of the oven for 50 mins-1 hr or until the cake is risen and golden (cover after 45 mins if the top gets too dark), and a skewer comes out clean. Leave to cool.
Mis the icing sugar with enough of the lime juice to create a thin icing. Pour over the cooled cake and top with the pistachio nibs and more zest to serve.
