Step 1

Preheat oven to 180°C. Brush an 18cm (base measurement) square cake pan with melted butter. Line with non-stick baking paper, allowing the edges to overhang.

Step 2

Process flour, sugar, baking powder and 50g (2/3 cup) of coconut in a food processor for 20 seconds. Add butter, eggs, lime juice and lime rind. Process until well combined.

Step 3

Pour into the pan and smooth the surface. Bake for 40 minutes. Sprinkle with remaining coconut and bake for a further 10 minutes or until a skewer inserted into centre comes out clean. Set aside for 5 minutes to cool slightly. Transfer to a wire rack to cool completely.
