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 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.
Using full-fat sweetened condensed milk, instead of skim or light, makes the slice set firmer.
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.
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.
Take your slice out of the fridge at least 20 minutes before cutting into pieces - this will help the chocolate from cracking when cut.
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.

Hi Lucy, we made this yesterday, texture was great - chocolatey and chewy. My daughter didn't like nuts so we omitted it. When I put the base into the pan, it was very glossy of butter on top (I dabbed it off with tissues), like the butter didn't mix into the mixture properly? Why do you think could be? I weighed everything and followed as per instructions (I used malted biscuits).
Lucy
Hi Thao, the base will look quite glossy thanks to the butter. As long as you mixed it well, it will be absolutely fine once chilled!
Rachael
I just made this! Texture is great and recipe is so easy... but it’s sooooo rich and a little bitter, I think I could possibly have omitted the extra cocoa powder. Or used a mixture of milk and dark melts
Lucy
Hi Rachael, hmm I haven't found it to be bitter. I wonder if it might be the brand of cocoa used? I generally use Nestle or Cadbury cocoa which is not too strong flavoured. Good luck! xx
Alexi
Hi there. Where are the quantities for this recipe..I can't see them anywhere!

ray
Is the 150 grams chocolate for the top or the centre?
Lucy
Hi Ray, 150g is for the base and an extra 290g is for the top.
Tyler
I made this! The base was very sticky and wet and didnt set, I measured the correct ingredients why do you think it turned out this way
Lucy
Hi Tyler, it could depend on the brand of biscuits you used. Also, I'm not sure if you measured in cups or grams (grams is always the most accurate way). The only other thing I can think of it if you used skim condensed milk? This doesn't set as well as full fat condensed milk. I hope that helps!
Marjo
Check the size of biscuit packet. They used to be 250gms but some are only 200gms!!! I also added finely diced dried apricot into mixture .....rather yummy.
Marjo
Forgot to mention,that if biscuits are only 200gms you can bulk it up with something bland like oats, rice bubbles or weetbix otherwise mixture is too sickly sweet and wet. I probably wouldn’t use sultans as they are sweet. Happy cooking and eating!!!
