Ingredients
  

For the Cake:

  • 250 g digestive biscuits or Marie biscuits, rich tea biscuits
  • 200 g dark chocolate semi-sweet or milk chocolate works too
  • ½ cup 115g unsalted butter
  • ¼ cup 60ml heavy cream or whole milk
  • ¼ cup 60ml honey or golden syrup
  • 2 tablespoons cocoa powder
  • 1 teaspoon vanilla extract optional
  • Pinch of salt

Optional Add-Ins:

  • ½ cup chopped nuts almonds, walnuts, hazelnuts
  • ¼ cup dried fruits raisins, cranberries, chopped apricots
  • 1 tablespoon instant coffee powder or orange zest for extra flavor
  • 2 tablespoons rum or whiskey for an adult version

Instructions
 

Step 1: Prepare the Ingredients

  • Line a Cake Pan: Use parchment paper to line a loaf tin, round cake pan, or square dish.
  • Crush the Biscuits: Place the biscuits in a ziplock bag and use a rolling pin to break them into small pieces. Avoid crushing them into fine crumbs; keeping some chunks adds texture.

Step 2: Make the Chocolate Mixture

  • Melt the Chocolate: In a saucepan over low heat, melt butter and chocolate together. Stir until smooth.
  • Add the Cream & Sweetener: Pour in the cream (or milk) and honey (or golden syrup). Mix well.
  • Enhance the Flavor: Stir in cocoa powder, vanilla extract, and a pinch of salt. If using nuts, dried fruits, or alcohol, add them at this stage.

Step 3: Combine and Shape

  • Coat the Biscuits: Pour the melted chocolate mixture over the crushed biscuits. Gently stir to coat all pieces evenly.
  • Transfer to the Pan: Press the mixture firmly into the lined cake pan using a spatula. Smooth the top.

Step 4: Chill and Serve

  • Refrigerate the Cake: Cover and place it in the fridge for at least 3 hours or until firm.
  • Slice and Enjoy: Once set, lift the cake out of the pan, slice into portions, and serve!
