Notes
Powdered sugar: if you don't have any powdered sugar/icing sugar than you can use castor sugar or regular granulated sugar. Just pop it in to a blender/spice/coffee grinder and grind until the consistency resembles that of powdered sugar/icing sugar. You can use white/light brown sugar.
Salt: so not add additional if you are using salted butter as you don't want the cookies to be too salty.
Add-ons: you can easily add chopped nuts, chocolate chips, small nougat pieces etc. You can experiment as you like. I prefer chopped almonds. You can also melt some chocolate and once the cookies have cooled down, you can dip them in chocolate - divine!
