Step 1

Line base and sides of a deep, 22-23cm loose-bottomed round tin with baking parchment. Mix the biscuits, melted butter and 2 tbsp of the sugar, then press into base. Chill while you make the filling.

Step 2

Divide cream cheese and cream evenly between 2 bowls. Add the white chocolate to one, and the milk chocolate, malt and remaining 3 tbsp sugar to the other. Beat each with an electric whisk until smooth.

Step 3

Spread the milk chocolate mixture evenly in the tin. Wipe round the edge to give a smooth edge. Spoon the white chocolate mix over the top and gently smooth. Decorate with Maltesers and chill for at least 5 hrs until firm.
