Preheat oven to 200°C. Grease 2 oven trays.
Combine butter, golden syrup and sugars in a medium heavy-based pan. Stir over low heat until butter is melted; cool for 5 minutes. Stir in flour and cinnamon.
Roll rounded teaspoons of mixture into balls. Place about 2cm apart on greased oven trays. Gently flatten with a floured fork until 1cm thick. Bake for about 12 minutes or until browned. Stand for 1 minute before lifting onto wire racks to cool.
