397g (14oz) of condensed milk
275g (10oz) icing sugar
350g (12oz) desiccated coconut
1 teaspoon vanilla essence
Food colouring of your choice
1 Lightly grease a 18cm (7in) square baking tin and line with greaseproof paper.
2 Place icing sugar, condensed milk and vanilla essence in a bowl and beat until thoroughly mixed.
3 Add the desiccated coconut and keep beating until thoroughly mixed. The mixture will be quite stiff but keep going until all the ingredients are well combined.
4 Divide the mixture in two. Spread the first half of the mixture evenly over the base of the prepared baking tin. Use your hand to level the mixture evenly.
5. Add a few drops of your chosen food colouring to the remaining mixture and mix well with a spoon. Once you’re happy with the colour, spread this mixture evenly over the plain mixture and level out.
6 Put the tin in the fridge and leave to set overnight or until firm. When set, remove the block from the tin and use a sharp knife to cut into squares.
