Ingredients
Method
Grease a 19cm square cake pan. Line the base and sides with baking paper, extending the paper 2cm above the pan edges.
Put dark chocolate, condensed milk, butter and golden syrup in a saucepan on medium heat. Stir over heat for 5 minutes, or until melted and smooth. Cool for 2 minutes.
Combine biscuits and coconut in a large heatproof bowl. Mix in the chocolate mixture to completely coat the biscuit mixture. Spoon the mixture into the prepared pan, pressing it well to compact. Cover. Refrigerate for 3 hours.
For Topping, put milk chocolate and butter in a microwave-safe bowl. Microwave on HIGH (100%) for 1 minute, or until melted and smooth, stirring halfway through cooking. Pour over the slice, spreading to level. Refrigerate for 1 hour or until set.
Remove the slice from the fridge 15 minutes before cutting into squares.

Storage tips
Store in an airtight container in the fridge for up to 1 week. Hedgehog slice also freezes well—wrap individual pieces in baking paper and store in a zip-lock bag for up to 2 months.
