In a large bowl, mix the flour, bicarbonate of soda and spices together. Add the butter and rub in with your fingertips until the mixture resembles fine breadcrumbs, then stir in the sugar.
In another bowl mix eggs, treacle and golden syrup/ honey.Please consider I used 300 g honey because treacle and golden syrup aren't common in Italy.
Mix the ingredients from the two bowls and knead until smooth.
Wrap in cling film and refrigerate for at least one hour.
Roll the dough on a slightly floured surface, cut your shapes ( there is enough dough for a small house too) and put them on a lined baking tray.
Bake in preheated oven at 180°C/ 360°F for about 15 minutes.
When completely cool mix icing sugar with some drops ( you need very little) of milk.Put the icing into a piping bag with a n.2 round nozzle ( writing nozzle) and decor your cookies.
They will last about a week into a tin box.
