Grease and line a 22cm X 32cm rectangular slice tin with baking paper.
Crush biscuits and place into a bowl.
Add coconut and grated lemon rind.
Mix to combine.
Add melted butter, condensed milk and lemon juice to the biscuit mixture.
Mix thoroughly until well combined.
Press into the prepared tin.
Place into the fridge.
In a bowl, whisk the icing sugar, room temperature butter and lemon juice in a bowl until creamy and ‘frosting-like’ – if the frosting is too thick to spread, add a little more lemon juice.
Spread the frosting over the slice, sprinkle with the extra coconut and place back into the fridge to set completely.
Cut into slices.
Store in an airtight container in the fridge for up to 1 week.
Recipe Notes
TIPS FOR FREEZING SLICES
you can freeze the slices as a whole or cut into individual pieces;
wrap the slice in plastic wrap then wrap in a layer of foil and place into an airtight container in the freezer (these 3 steps will keep your slices tasting great!);
slices with a soft filling (or cheesecakes) don’t tend to freeze well;
slices kept in the freezer will taste best within the first month, but can last longer.
