Preheat your oven to 180°C (350°F) and line a 9x9 inch (23x23 cm) square baking pan with parchment paper.
Step 2
In a mixing bowl, combine the flour, desiccated coconut, and melted butter. Mix until well combined.
Step 3
Press the mixture evenly into the bottom of the prepared baking pan. Use the back of a spoon to smooth it out.
Step 4
Bake in the preheated oven for 15-20 minutes or until the crust turns golden brown. Remove from the oven and let it cool slightly.
Step 5
In a saucepan over low heat, combine the brown sugar, sweetened condensed milk, and golden syrup. Cook, stirring constantly, for about 5 minutes or until the mixture thickens and turns a caramel color.
Step 6
Pour the caramel mixture evenly over the baked crust. Return it to the oven and bake for an additional 10-12 minutes or until the caramel is bubbling and golden.
Step 7
Remove from the oven and let it cool in the pan.
Step 8
In a microwave-safe bowl, melt the dark chocolate and vegetable oil together in 30-second increments, stirring until smooth.
Step 9
Pour the melted chocolate over the cooled caramel layer and spread it evenly.
Step 10
Refrigerate for at least 2 hours or until the chocolate is set.
Step 11
Once set, remove the caramel slice from the pan and cut it into 16 squares.
