Steps
- Preheat the oven to 350°F / 180°C. Grease and line a 16 × 12in / 40 × 30cm baking pan.
- Melt 375g of unsalted butter in a saucepan over medium heat. Dissolve 2 teaspoons of baking soda in 2 tablespoons of milk, then stir into the butter with 3 tablespoons of golden syrup.
- Mix 230g of rolled oats, 340g of sifted cake flour, 200g of unsweetened desiccated coconut, 275g of sugar, and 1 pinch of salt. Stir into the butter mixture until combined.
- Press firmly into the pan. Bake for 30 minutes, until golden. Cool slightly, cut into 1½in / 4cm squares, and leave in the pan until fully cool.
