Instructions
Biscuit Base
- Prepare Baking Pan: Line a 9 x 9 inch (22cm x 22cm) square baking pan with parchment paper. Set aside.
- Crush Biscuits: In a high-speed food processor, crush the biscuits to a fine crumb.
- Mix Base Ingredients: Transfer the biscuit crumbs to a large mixing bowl. Stir in the desiccated coconut, lemon zest and orange zest. Add sweetened condensed milk, melted butter, and lemon and orange juice. Mix with a wooden spoon or spatula until the mixture is well combined.
- Press into Pan: Press the mixture firmly into the prepared pan, using the back of a spoon, a spatula, or your hands. Place in the refrigerator to chill while preparing the icing.
Citrus Icing
- Make Citrus Icing: In a medium-sized mixing bowl, sift the icing sugar. Add melted butter and lemon and orange juice. Whisk until smooth and thick.
- Apply Icing: Spread the icing evenly over the biscuit base.
- Chill to Set: Return the pan to the refrigerator and chill for at least 2-3 hours, or until the icing is firm and the base is solid.
- Slice and Serve: Once set, remove the slice from the pan, peeling away the parchment paper. Cut into squares and enjoy!

- Storage: Store the slice in an airtight container in the refrigerator for up to 1 week.
- Freeze: For longer storage, wrap the entire slab or individual slices in cling film, then place in a freezer-safe bag or container. It can be frozen for up to 3 months.
- Thaw: Thaw the slices in the refrigerator overnight. For quicker thawing, leave them at room temperature for a few hours until they are soft enough to eat.
