    Delicious and truly as easy as described. I milled the orange rind with the sugar as an earlier comment suggested as I have two fussy boys who dont like lumps in their food. They loved this cake with no idea about the zucchini. Trying to give it 5 stars but cant get it to work!

  • Lovely flavours. I reduced

    Lovely flavours. I reduced sugar to 170g, butter to 140 g , flour to 190 g, but added 110 g almonds which I milled at the start and also 1 tsp baking powder. Will definitely make again. Also I peel off the Orange rind at the start and mill it with the sugar before I add the butter. This way the flavour infusers better.  tmrc_emoticons.)

    It does not give a temperature setting so I am assuming it is about 180 degrees.  I have used coconut sugar and a manderine instead of an orange.  Here is too fingers crossed it works.

  • Great recipe, I had no butter

    Great recipe, I had no butter so used peanut oil instead and used a tangerine instead of an orange. Lovely and moist because of the zucchini
