Preheat the oven to 350°F (175°C). Line a cookie sheet with parchment paper.

In a large bowl, mix the flour, sugar, desiccated coconut, rolled oats, and baking soda until evenly combined.

In a small saucepan over medium-low heat, melt the butter with the golden syrup, stirring until smooth.

Pour the melted mixture into the dry ingredients and stir until a thick dough forms.

Scoop portions, place on the cookie sheet, and flatten into thin rounds.

Bake for 10–12 minutes, or until golden brown.

Cool on the pan for 5–10 minutes, then transfer to a rack to cool completely and crisp up.
