Hedgehog Slice is a classic no bake, chocolate fudge recipe that only requires a handful of ingredients and minimal time setting in the fridge. This is a no bake hedgehog slice without condensed milk! With only six ingredients, this no bake hedgehog slice is a simple recipe for bakers of all skill levels.

I always think of hedgehog slice as a classic, easy NZ recipe like the lolly cake recipe. This was staple at my Grandmas house (though we just knew it as chocolate fudge) and everyone in the family who knew about the no bake chocolate slice recipe would walk in the house, head straight to the fridge and grab a few pieces before they were all gone. Needless to say, this recipe is nostalgic and a family favourite.
There are a lot of different ways to make hedgehog slice. Some use eggs and melted chocolate, others don't use melted chocolate at all. Some even use condensed milk! The commonality between all the recipes is the classic chocolate icing which is purely a touch of butter, warm water and icing sugar.
