    What You Need

    My no-bake chocolate hedgehog slice recipe couldn't be any easier to make... and all you need is a few pantry staples:

    Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.

    • butter - either salted or unsalted butter are fine to use in this recpe
    • sweetened condensed milk - use full fat - not skim
    • dark chocolate - choose any type of dark chocolate or dark chocolate melts (cooking chocolate). Alternatively you can use milk chocolate if you prefer.
    • plain sweet biscuits - (known as cookies in the US). I generally use Arnott's Marie biscuits, but you can use any type of plain biscuit/cookie you like
    • desiccated coconut - which is finely shredded dried coconut 
    • walnuts - omit for a nut-free version (see notes below)
    • cocoa powder - choose a cocoa powder such as Cadbury, Hersheys or Nestle brand.

    The ingredients for chocolate hedgehog slice.

    Step By Step Instructions

    With just 15 minutes prep time and a few basic steps, this chocolate hedgehog slice recipe could not be easier making it the perfect recipe for beginners through to experienced cooks.

    Note: Please scroll to the recipe card at the bottom of the post for ingredient quantities and the full detailed method.

    Step 1 - Melt

    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.

    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.
