What You Need
Just 6 basic ingredients is all you need to make this classic no-bake lemon coconut slice.
Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.
For The Slice:
- Butter - you can use either salted or unsalted butter in this recipe
- Sweetened condensed milk - choose full fat sweetened condensed milk (not light or skim versions as they don't set as firmly)
- Plain sweet biscuits - like Arnott’s Marie biscuits in Australia, graham crackers in the US, or digestive biscuits
- Desiccated coconut - use fine dried desiccated coconut in this recipe
- Lemon juice
- Lemon zest - finely grate the yellow part of the lemon rind
For The Frosting:
- Icing sugar - choose pure icing sugar for a firmer frosting. Icing sugar mixture will result in a softer icing. I prefer to use pure icing sugar as the firmer frosting is more suitable for lunch boxes.
- Butter - you can use either salted or unsalted butter in this recipe
- Lemon juice
- Desiccated coconut - for sprinkling over the top

Note: Scroll to the recipe card at the bottom for the ingredients quantities and full detailed method.
Step 1 - Crush The Biscuits
Use a food processor, a rolling pin or your Thermomix to crush the biscuits into fine crumbs (a few larger chunks is fine too).
Step 2 - Mix
Mix through the coconut and lemon zest until combined.
Step 3 - Add The Wet Ingredients
Stir through the melted butter, sweetened condensed milk and lemon juice.
Mix until combined.
Step 4 - Press Into Tin
Use the back of a spoon to spread out the slice evenly and press the mixture very firmly into the tin.
Place in the fridge to chill while you prepare the frosting.
Step 5 - Make The Frosting
Whisk together the room temperature butter, icing sugar and lemon juice until smooth and creamy.
Spread evenly over the slice making sure it is completely covered in a layer of icing.
Sprinkle the extra coconut over the top and chill in the fridge. That's it!
Tips For Making The Perfect Lemon Frosting
Follow these simple tips for a beautiful and creamy lemon frosting:
- Use pure icing sugar (as compared to icing sugar mixture) as it will set the frosting firm when placed in the fridge. This is especially important when sending the slice in school lunch boxes
- Sift the icing sugar before using to remove any lumps (pure icing sugar tends to have more lumps than the softer icing sugar mixture so don't miss this step!)
- Use room temperature butter
- If your frosting is too thick to spread, add a small amount of extra lemon juice and mix again
- If your frosting is too soft, add some extra icing sugar
- Whisk the frosting until it's smooth and creamy and no lumps of butter or icing sugar remain
FAQ
Yes, absolutely! Click here for the coconut lime slice no-bake recipe.
You can use any type of plain sweet biscuits for the base (like graham crackers in the US, or digestive biscuits). Simply crush until fine crumbs remain (a few chunks are fine!)
I prefer a firm frosting on my lemon coconut slice and so I use pure icing sugar instead of icing sugar mixture. Once I've mixed it together, I add a little extra pure icing sugar if I think it's not thick enough. It should be quite difficult to stir and spread at this stage. Use a hot knife to spread the frosting over the base.
This slice will last for up to 7 days in an airtight container in the fridge.
Alternatively, it can be frozen in an airtight container for up to 2 months and brought to room temperature before consuming.
