Measure out the flour, sea salt, baking powder and paprika in a separate bowl, then fold into the eggs, followed by the buttermilk and olive oil. Roughly chop the sun-dried tomatoes, olives and hazelnuts and add to the batter. Grate the courgette on the coarse side of a box grater and add. Crumble in the goat’s cheese in bite-sized chunks.
