Layer 4 – White Chocolate Cornflake Crunch
- 150g white chocolate (5.3 oz)
- 75g cornflakes, lightly crushed (3 cups)

Instructions:
Step 1:
Make the Blondie Base
- Line your tin with parchment.
- Melt 150g white chocolate with 100g butter in a heatproof bowl (microwave in 20-sec bursts or over a pan of simmering water). Let cool slightly.
- Whisk in 100g brown sugar, then 2 eggs, and vanilla until smooth.
- Fold in 100g flour and pinch of salt until just combined.
- Gently fold in 100g white chocolate chunks.
- Pour into the prepared tin and smooth the top.
- Bake at 160°C fan (350°F) for 20–25 mins – until the edges are golden and the centre is just set (a little wobble is okay).
- Cool completely in the tin.
Step 2:
Make the Firm White Chocolate Ganache
- Put 100ml of double cream and 250g of white chocolate in a microwaveable bowl
- Ensure Microwave is set to 50%-70% Power
- Heat for 20 second increments, stirring gently.
- Pour ganache over the cooled blondie base. Tilt gently to spread.
- Chill in the fridge for 20–30 minutes, until slightly firm but still tacky.
Step 3:
Add the White Twix Layer
- Place whole White Twix bars in a single layer over the ganache. Press in gently so they stick but don’t sink.
- Chill again for 15 minutes while you make the topping.
Step 4:
Make the Cornflake Crunch Topping
- Melt 150g white chocolate (microwave in short bursts or over a double boiler).
- Stir in 75g crushed cornflakes and a pinch of salt (optional).
- Spread the mixture gently over the Twix bars to fully cover them.
- Chill for at least 2 hours or until fully set.
