Preheat oven to 180c/Gas Mark 4. Line a baking tray with baking paper.
Cream butter & sugar in a large bowl. Mix in the golden syrup and gradually add the egg - beating well.
Sift the flours, ginger & baking powder into the bowl and mix until a dough is formed.
Gather the dough into a ball with floured hands and roll out onto a floured surface until approx 0.5cm thick.
Use a cutter to cut shapes from the dough and place carefully on the baking tray. Gather the offcuts and repeats until all the dough is used.
Cook for 8mins or until browned. Leave to cool on the tray.
When completely cool, mix the icing sugar with a little water until it is thick but still slightly runny. Use a piping bag to decorate your gingerbread shapes and stick smarties on!
