Ingredients
300g (10.5 oz) digestive biscuits or tea biscuits (Marie or Rich Tea work great)
200g (7 oz) dark or semi-sweet chocolate, chopped
100g (3.5 oz) milk chocolate, chopped
100g (3.5 oz) unsalted butter
120ml (½ cup) heavy cream
3 tbsp golden syrup or honey
1 tsp vanilla extract
Optional add-ins: chopped nuts, dried fruits, or mini marshmallows
Optional Ganache Topping:
100g (3.5 oz) dark chocolate
100ml (⅓ cup + 1 tbsp) heavy cream
Instructions
Step 1: Prep the Biscuits
Break the biscuits into small pieces (about 1–2 cm chunks). Do not crush them into crumbs—texture is key!
Step 2: Make the Chocolate Mixture
In a saucepan, heat butter, cream, golden syrup, and both chocolates over low heat. Stir until smooth and glossy.
Remove from heat and stir in the vanilla extract.
Step 3: Combine and Shape
Pour the chocolate mixture over the biscuit pieces. Stir gently to coat everything evenly.
Transfer the mixture into a lined 8-inch round or loaf pan. Press it down evenly with a spatula or the back of a spoon.
Step 4: Optional Ganache Topping
Heat cream and pour it over the chopped chocolate. Let sit for 2 minutes, then stir until smooth.
Pour over the cake and smooth out.
Step 5: Chill and Set
Refrigerate for at least 3–4 hours, or until firm.
Remove from the pan, slice, and serve!
