* Preheat the oven to 170c/350f/gas mark 4 before you begin.
* Sift the flours and cocoa together into a mixing bowl, add the sugar and mix well.
* Add the butter. Using just the tips of your fingers, rub together the ingredients until the mixture resembles fine breadcrumbs.
* When all the butter is evenly mixed in, make a well in the centre and add the syrup and the egg.
* Mix well, drawing in any of the flour left at the sides of the bowl and stop as soon as a ball has formed.
* Place the dough onto your clean worktop. Divide into two and squash the dough into two even-sized flat discs. Cover and chill until ready to use, or roll out immediately.
* Easter egg shaped cutters are widely available online, or you can choose to make your own. Simply identify the egg size you want to trace and lay a sheet of parchment on top, carefully tracing around. Carefully cut the template out with scissors. You can find some of our favourite templates in the Biscuiteers Book of Iced Biscuits.
* If you are planning to hang your biscuit eggs on your Easter tree, now is the time to pierce the holes. The best way to do this is with a straw.
* Bake in the oven for 14-18 minutes until golden brown.
* Remove the trays from the oven and transfer the whole sheet of parchment to a cooling rack.
* Leave to totally cool before starting to ice.
