Grease and line a rectangular slice tin.

Melt the butter, chocolate and sweetened condensed milk in the microwave (or on a stove-top or in a Thermomix).

Stir until completely melted and combined.

Mix through the crushed biscuits, coconut, walnuts and cocoa powder.

Stir until the dry ingredients are well coated.

Expert Tips & FAQ

Hedgehog slice is so quick and easy to make!

Here's a few tips for making it perfectly every single time:

Line the baking tin

Line the baking tin with baking paper and allow the paper to hang over the edges - this will make it much easier to remove from the tin once set.

Why should I use full-fat sweetened condensed milk?

Using full-fat sweetened condensed milk, instead of skim or light, makes the slice set firmer.

Can I make this nut-free?

Of course! You can omit the walnuts for a nut-free version -either replace with sultanas or if omitting entirely, reduce the amount of sweetened condensed milk by approximately 50g.

Why add coconut oil or vegetable oil to the chocolate layer?

Adding a small amount of vegetable oil or coconut oil to the melted chocolate that is poured over the top of the slice will help it to stop cracking when cut into pieces. It is optional, but I find it really helpful.

Cutting the slice

Take your slice out of the fridge at least 20 minutes before cutting into pieces - this will help the chocolate from cracking when cut.

Storing

Store the slice in an airtight container in the fridge for up to 5 days.

Freezing

Freeze the slice in an airtight container with greaseproof baking paper between each layer for up to 3 months.
