How to Make No-Bake Rocky Road Slice

1. Prepare the Pan: Grease a 20cm square cake pan that s 4.5cm deep. Line the base and sides with baking paper, ensuring you have a 2cm overhang on each side for easy removal.

2. Make the Base: Process the plain chocolate biscuits until finely chopped, then add the melted butter. Mix until combined. Press the biscuit mixture firmly into the base of your prepared pan. Cover and refrigerate for 30 minutes to set.

3. Dissolve Gelatine: In a heatproof jug, combine the boiling water and powdered gelatine. Stir until fully dissolved and set aside. In a saucepan, combine the marshmallows and milk over medium heat, stirring until the marshmallows melt into a smooth mixture.

4. Combine Mixtures: Transfer the melted marshmallow mix to an electric mixer. Gradually beat in the dissolved gelatine until well combined. Spread this marshmallow layer evenly over the chilled biscuit base. Cover and refrigerate for another 30 minutes until set.

5. Prepare the Chocolate Topping: In a large microwave-safe bowl, combine the CADBURY Baking Milk Chocolate Blocks with the chopped butter. Microwave on medium (50%) for 1 to 2 minutes, stirring every 30 seconds until the mixture is smooth.

6. Add the Crunch: Stir in the dry-roasted almonds, shredded coconut, and halved glace cherries into the chocolate mixture until well combined. Spoon this over the marshmallow layer, pressing it down to level it out.

7. Chill to Set: Refrigerate for 1 hour until the chocolate topping is firm. Once set, carefully remove the slice from the pan using the overhanging baking paper.

8. Serve: Cut into squares and serve your delicious no-bake rocky road slice.

Optional: Drizzle with extra melted chocolate for a delightful finish.
