A. List of ingredients

  • 200g (7 oz) of plain sweet biscuits (such as Marie or Digestive)
  • 1/2 cup of desiccated coconut
  • 1/2 cup of chopped walnuts
  • 1/2 cup of cocoa powder
  • 1 cup of sweetened condensed milk
  • 125g (4.4 oz) of unsalted butter, melted
  • Extra chopped walnuts and coconut for topping (optional)

B. Explanation of why each ingredient is important

  • Plain sweet biscuits: These biscuits provide the base and texture for the slice. They are crushed and combined with the other ingredients to create a crunchy and crumbly texture. Marie or Digestive biscuits are commonly used, but you could also use graham crackers or other plain biscuits.
  • Desiccated coconut: Adds flavor and texture to the slice. If you don’t like coconut, you can omit it or replace it with another ingredient such as crushed cornflakes or chopped dried fruit.
  • Chopped walnuts: Adds crunch and nutty flavor to the slice. You can substitute with other nuts such as almonds, pecans or hazelnuts.
  • Cocoa powder: The main flavoring ingredient that gives the slice its rich chocolate taste.
  • Sweetened condensed milk: Binds all the ingredients together and adds sweetness to the slice. You can use unsweetened condensed milk if you prefer less sweetness.
  • Unsalted butter: Helps to bind the ingredients together and adds richness to the slice. You can use salted butter if you prefer a slightly saltier flavor.

C. Possible substitutions or modifications

  • You can add raisins or other dried fruits to the mix for a more fruity taste.
  • For a vegan version, substitute the sweetened condensed milk with coconut cream or condensed coconut milk.
  • To make it gluten-free, substitute the plain biscuits with gluten-free biscuits or rice cakes.
  • Instead of topping with chopped walnuts and coconut, you can use sprinkles, melted chocolate or other decorations.
