- 300 g milk chocolate or semisweet chocolate
- 150 g dark chocolate (for richness)
- 120 g butter
- ½ cup sweetened condensed milk (or ½ cup heavy cream)
- 1 teaspoon vanilla extract
- Pinch of salt
Crunch additions (choose 1–3)
- 200 g digestive biscuits or tea biscuits (roughly crushed)
- OR 3 cups rice krispies
- OR chopped wafers
- OR cornflakes
- OR roasted nuts (almonds, hazelnuts, peanuts)

Outer coating

- 1 tablespoon oil or butter
- ½ cup puffed rice or crushed nuts (for crunch)
Optional extras
- Mini marshmallows
- Dried fruit

🍫 Step 1 — Melt the Chocolate Base
Place dark and milk chocolate in a heatproof bowl with butter.
Melt gently using one of two methods:
Double boiler:
Place bowl over simmering saucepan (don’t touch water), stir until smooth.
Microwave:
Heat 20–30 seconds at a time, stirring between bursts.
Add condensed milk or cream, vanilla, and pinch of salt.
Stir until silky and glossy.
🔨 Step 2 — Add the Crunch
Place crushed biscuits and/or chosen mixers in a bowl.
Pour warm chocolate mixture over the crunch elements.
Stir well to coat every piece — this ensures every bite gets that perfect texture.
If adding marshmallows or dried fruit, mix them gently at this stage.
The mixture should be thick but spreadable.
If too liquidy, add more crushed biscuits.
📦 Step 3 — Shape the Cake
Line a loaf tin with parchment paper, leaving sides hanging for easy removal.
Pour mixture into the tin, pressing with a spatula to eliminate air pockets.
Smooth the top evenly.
Cover and refrigerate 2–4 hours until solid.
Freeze 30 minutes if you want faster results.
🍫 Step 4 — Chocolate Crunch Coating
Melt chocolate + 1 tablespoon oil until smooth.
Stir in puffed rice or crushed nuts.
This gives the incredible bumpy coating you see in the picture!
Remove cake from tin and pour or spread coating evenly all over, using spatula to cover edges.
Let set in fridge 20–30 minutes until firm.
🔪 Step 5 — Slice & Serve
Use a sharp knife warmed in hot water (dry before cutting) for clean slices.
Serve at:
- Room temperature for soft fudge texture
- Chilled for candy-bar style firmness
Each slice will reveal ribbons of chocolate with crunchy surprises throughout — a total showstopper.
