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 is fine to use in this recipe
- 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 biscuits or cookies 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 from Cadbury, Hershey's, or Nestle.
- Vegetable oil or coconut oil is optional. This helps to prevent the chocolate layer from cracking when it is cut into pieces.

To make this easy hedgehog slice, you will need:
- food processor, blender, Thermomix or rolling pin for crushing the biscuits
- large mixing bowl
- microwave, stovetop or Thermomix for melting the chocolate

Step By Step Instructions
With just 15 minutes of 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 (18cm X 28cm).
Melt the butter, chocolate and sweetened condensed milk in a large bowl in the microwave on low heat in 30 second burts (alternatively, you can melt the ingredients on a stove-top over low heat or in a Thermomix).
Stir the chocolate mixture until completely melted and combined.
Step 2 - Mix
Mix through the crushed biscuit crumbs, coconut, walnuts and cocoa powder.
Stir until the dry ingredients are well-coated.
Step 3 - Press Into Tin
Press the mixture firmly into the prepared baking tin. Use the back of a spoon to evenly smooth the surface.
Step 4 - Top With Chocolate
Melt the extra dark chocolate mixed with coconut oil/vegetable oil (optional) and pour the chocolate topping over the slice.
Chill in the fridge for at least 3 hours before cutting into small pieces.
Expert Tips
No bake hedgehog slice is so quick and easy to make and is the perfect sweet treat!
Here are a few tips for making it perfect every single time:
- 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.
- Use full-fat sweetened condensed milk instead of skim or light as it makes the slice set firmer.
- Nut free - You can omit the walnuts for a nut-free version - either replace them with sultanas or, if omitting them entirely, reduce the amount of sweetened condensed milk by approximately 50g.
- Cutting the slice - Take your slice out of the fridge for at least 20 minutes before cutting it into pieces - this will help prevent the chocolate from cracking when cut.
- Storing & Freezing - Store the slice in an airtight container in the fridge for up to 5 days. Freeze the slice in an airtight container with greaseproof baking paper between each layer for up to 3 months.
FAQs
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.
Yes you can! I have included both the conventional method and the Thermomix method for preparing hedgehog slice in the recipe card below.

I liked this recipe, because it had less butter than other hedgehog recipes, and no extra added sugar, just what is in the condensed milk, and choc, which I used dark chocolate. I made this and it turned out great. So yummy! My youngest son doesn't like the coconut bits, but my oldest son doesn't mind them, he loves it! I didn't add the walnuts, but maybe next time ☺

I make this often for my partner who is a Hedgehog lover. This recipe is a winner and oh so easy. Love a no bake recipe. Today I subbed the extra dark chocolate for white chocolate and sprinkled some mini M&M’s over the top. Fingers crossed it’s just as good as the original.
Charlie
Hello. Just want to clarify please, there are two quantities of dark chocolate, one is called 'extra dark chocolate'. But in the recipe, only 'dark chocolate' is referred to and I'm not clear on which quantity is which. Could you please clarify? is 'extra dark' referring to 70% dark chocolate? is this the one that is used for the topping?
Thanks!
Lucy
Sorry the extra just means in addition to! Thjis is for the topping!
