Hedgehog Slice

  • 250 grams digestive biscuits* (about 17 biscuits or 9 oz)
  • 1/2 cup chopped walnuts (65 grams)
  • 1/2 cup desiccated coconut (50 grams)
  • 85 grams unsalted butter (6 tablespoons)
  • 3 tablespoons cocoa powder
  • 1 395 gram tin sweetened condensed milk (14 oz can)
  • 250 grams dark chocolate* (9 oz)

Chocolate Topping

  • 150 grams milk chocolate* (5.3 oz)
  • 2 teaspoons vegetable oil


Hedgehog Base

  • Line a slice pan (18x28 cm or 20x20 cm/ 8x8 inch) with parchment paper leaving an overhang around the sides.
  • Break up the biscuits by hand so that there are both pieces and crumbs and place in a large glass bowl. Add in the chopped walnuts and coconut.
  • Add the butter, cocoa, sweetened condensed milk and dark chocolate to a medium saucepan over low heat. Melt together while gently stirring until smooth.
  • Pour the mixture over the dry ingredients, and stir to combine.
  • Pour into the prepared pan, press down frim, and place in the fridge to chill for 30 minutes.

Chocolate Topping

  • Add the chopped chocolate to a microwave-safe bowl. Microwave for 30-second intervals on medium power (NOT high), stirring between each, until just melted.
  • Stir in the oil.
  • Pour the chocolate over the bars, and spread smooth.
  • Place back in the fridge to set (about 1-2 hours).
  • When firm, slice into squares. For easier slicing - when the chocolate is about 75% hardened, score the top with a thin knife where you plan to cut the bars.


1.Graham crackers or Arnott's Marie biscuits also work.
2.I used 50% dark chocolate in the base. Semi-sweet or 60% dark chocolate work too. I wouldn't use milk chocolate or any stronger form of dark chocolate in the base. For the topping you could use milk, dark or semi-sweet chocolate.
