In a medium saucepan, melt the butter and golden syrup. Dissolve the baking soda with hot water in a small bowl and add it to the butter and golden syrup. Be careful as the hot mixture will bubble up. Remove it from the stove.
1/2 cup butter, 2 tbsp golden syrup, 1 tsp baking soda, 2 tbsp filtered water
In a large bowl, combine the dry ingredients including flour, sugar, desiccated coconut, and rolled oats.
1 cup all-purpose flour, 3/4 cup brown sugar, 3/4 cup desiccated coconut, 1 cup rolled oats
Add the wet ingredients to the flour mixture. Mix until everything is well combined. Shape the dough into a large ball.
Cover the bowl with a tea towel and place it in the fridge for 30 minutes.
Preheat the oven to 350F/180C and line a cookie tray with parchment paper.
Remove the dough from the fridge and form 12 balls. Place them onto the tray and space them out well.
Bake for 12 minutes and remove the biscuits from the oven. If you bake them longer, the biscuits will be crunchy instead of chewy.
Let them cool on a wire rack and enjoy!
Notes
Be careful when adding the baking soda to the hot butter mixture as it will bubble up.Make sure the wet mixture doesn't simmer or boil.By chilling the dough in the fridge for 30 minutes before baking, the biscuits will hold their shape during baking and get their chewy texture.
