Turn off the heat, add the crushed biscuits and cocoa and mix thoroughly, ensuring the chocolate colour is evenly distributed. Add the fruit and mix carefully
Press the mixture into the tin with the back of a spoon. Push it down firmly. Turn the spoon over and use the edge to tidy up the edges of the tiffin
Leave to cool.
FOR THE TOPPING:
When the base has cooled, tip the tiffin out of the tin and remove the liner

Leave to cool, then cut into squares.
Notes
Everyday Cooks tips:
If the cocoa has lumps, don’t bother to sift it. Just make sure you mix it in thoroughly, pressing the lumps out as you go.
Storage - Chocolate Tiffin keeps well for a week or so in an airtight tin or plastic box. It will keep for longer in the fridge, but the chocolate may look less shiny.
