Chocolate Hedgehog Slice Recipe

This no-bake chocolate hedgehog slice combines the crunch of Marie biscuits with the nuttiness of walnuts, the sweetness of desiccated coconut and the richness of cocoa powder all bound together with a luscious mixture of condensed milk and butter.

I’ve refined the base of this hedgehog slice by omitting melted chocolate, as combining it with sweetened condensed milk made it excessively sweet.

This adjustment ensures the slice retains the classic hedgehog flavor without the overpowering sweetness, especially since there’s also a melted chocolate topping.

Why is it called hedgehog slice?

The hedgehog slice gets its name from its appearance. Once the slice is cut, the surface, studded with bits of crushed biscuits and sometimes nuts, resembles the spiky back of a hedgehog.

It’s popular in Australia and New Zealand and is known for its delicious chocolate texture combined with crunchy biscuit pieces!

Can I use dark chocolate for the topping instead of milk chocolate?

Absolutely! Dark chocolate can be used for a richer taste instead of milk chocolate.

What can I use instead of walnuts in the recipe?

If you’re allergic to walnuts or simply prefer another option, almonds, pecans, or even pistachios make great substitutes. You can also use seeds like sunflower or pumpkin seeds for a nut-free version. Or you can simply leave the walnuts out of the recipe and add more desiccated coconut.

Expert Tips

  • Biscuit Texture: Break the biscuits into uneven pieces for a more interesting texture.
  • Cutting the Slice: To cut clean slices without cracking the chocolate, let the slice sit at room temperature for about 10 minutes before cutting. Use a sharp knife warmed under hot water and wiped dry to slice through the chocolate layer neatly.

Ingredients
 
 

Base

  • 250 g (8.9 oz.) Marie biscuits, or arrowroot / plain digestives biscuits
  • 1/2 cup desiccated coconut
  • 1/2 cup walnuts, roughly chopped
  • 3 Tbsp unsweetened cocoa powder
  • 3/4 cup (225g) full-fat sweetened condensed milk
  • 200 g unsalted butter, cubed

Topping

  • 180 g milk chocolate block, broken into squares
  • 2 tsp coconut oil, or vegetable oil

Instructions
 

Base

  • Line Tin: Line a 11 x 7-inch (20cm x 30cm) brownie pan with parchment paper. Set aside.
  • Prepare Biscuits: In a high-speed food processor, crush biscuits, leaving about half the biscuits in larger pieces. Alternatively, you can do this by placing them in a zip-lock bag and crush them using a rolling pin. Set aside.
  • Combine Dry Ingredients: Add the biscuits to a large mixing bowl. Add the coconut, chopped walnuts and cocoa powder. Mix until well combined. Set aside.
  • Melt: In a saucepan, add the condensed milk and cubed butter and slowly melt over low-medium heat, stirring until completely melted and the mixture is smooth. Remove from the heat.
  • Combine: Pour the melted condensed milk and butter mixture into the dry biscuits. Use a wooden spoon or spatula to mix until well combined.
  • Transfer Mixture: Spoon and press the mixture firmly into the lined pan. Set aside.

Topping

  • Melt Chocolate: Melt the broken up milk chocolate with the coconut oil in a double boiler over low heat or microwave until smooth.

  • Pour and Spread: Pour the melted chocolate over the base. Move the pan around with your hands to evenly spread the chocolate.

  • Chill: Chill for 1-2 hours or until firm. Cut into squares and enjoy!

  • Slice and Serve: Lift it out of the tin and place it on a cutting board. Let it sit for about 10 minutes for the chocolate to come slightly to room temperature so it does not crack when you cut it. Run your knife under hot water, wipe it dry then cut the hedgehog into squares. Enjoy!

Notes

  • Storage: Store the hedgehog in an airtight container in the refrigerator for up to 1 week.
 
  • Freeze: For longer storage, wrap the entire slab or individual slices in cling film, then place in a freezer-safe bag or container. It can be frozen for up to 3 months.
