Why you’ll love this recipe
- Quick and easy – all you need is one bowl, a slice tin and about 5 minutes to prepare!

Ingredients you will need
Ingredient notes
- Sweet cookies – store bought are best here! And any type of plain, sweet biscuit can be used. If you’re in Australia, I recommend using Marie, Arrowroot or Digestives. In other areas like the US, Graham crackers or any other sweet-tea cookie will work.
- Coconut – I use desiccated coconut for the finer crumb and texture. Shredded coconut can also be used, but the texture of the base will be different.
- Butter – you will need real, unsalted butter for this recipe rather than margarines or dairy spreads.
- Lemons – fresh lemons are highly recommended, because we will be using both the zest and freshly squeezed juice. Bottled juice just won’t have the same taste.
Step by step photos
Once the biscuits have been crushed to the desired consistency and mixed with the coconut, the melted butter, condensed milk, lemon zest and juice is added to form the base of the slice.
Use a metal spoon to firmly press the biscuit base into the prepared slice tin. To finish, use your fingers to press the edges.
Mix the icing to your desired consistency and spread over the base. Add the slice to the refrigerator and allow to set for 3 hours, or overnight. Sprinkle with a little extra lemon zest and coconut and use a clean, sharp knife to cut into slices of desired size.
FAQs
How do you store lemon slice? Keep it in the fridge in an airtight container for 4-5 days (if it lasts that long!).
Can I freeze this? Yes! Once set, the slice can be cut into individual pieces, wrapped in paper and frozen in an airtight container for up to 2 months. To thaw, simply place the pieces out at room temperature for around 30 minutes, or add them to the fridge overnight.
Which lemons are best? I love Meyer lemons for their sweet flavour and high juice content. But any lemons will work fine! For something a little different, you can also make lime slice or any other citrus slice by simply switching the lemons for your favourite citrus fruit.
Handy tips
- For the perfect lemon icing, sift the icing (confectioners) sugar before mixing, to avoid lumps. If your icing is too runny, add a little more icing sugar. If it’s too thick, add a little extra lemon juice.
- I use a rolling pin to crush the biscuits, either in a mixing bowl or bag. I prefer this method because I like to leave larger chunks of crunchy biscuits throughout the mixture. Smashing them with a rolling pin is also quite therapeutic! If you prefer a finer base, the biscuits can also be added to a food processor and blended until fine.
- For a tropical twist, add 2-3 tablespoons of passion fruit pulp to the icing. You will need to use a little less lemon juice to prevent the icing from becoming too runny.
- Use a little extra zest and coconut to sprinkle over the top of the finished slice!

Lemon Coconut Slice
Ingredients
For the slice
- 400 grams Arnott's Marie biscuits or any other plain, sweet biscuit (Arrowroot, Digestives, Graham Crackers). Around 4 cups.
- 1 ½ cups desiccated coconut
- ⅓ cup melted butter around 85 grams
- 1 cup sweetened condensed milk 1 x 395 g can.
- zest of 2 lemons
- 3-4 tbsp lemon juice
For the lemon icing
- 4 cups icing sugar sifted
- 5-6 tbsp lemon juice
- 2 tsp butter melted
- zest of one lemon
Optional
- additional coconut and lemon zest, to top
Instructions
For the slice
- Prepare a 16 cm x 26 cm slice tin (with sides at least 3 cm high) by adding a layer of baking/parchment paper.
- Place the biscuits/cookies into a large mixing bowl or bag and use the end of a wooden rolling pin to press down on the biscuits until they are mostly fine crumbs mixed with some larger pieces. Alternatively, place the biscuits into a food processor and blend until the mixture resembles fine crumbs.
- Add the coconut to the crushed biscuits and then add the butter, condensed milk, zest and juice.
- Stir until completely combined.
- Pour the biscuit base mixture into the prepared tin and use a metal spoon to firmly press the base into the tin. Use your fingers to finish any rough edges.
For the icing
- Add the icing ingredients together in a mixing bowl and beat until completely combined and smooth. The icing should be thick enough to almost hold its shape. If too runny, add a little more icing sugar. If it is too thick, you can add a little more lemon juice or a little milk.
- Spread the icing over the top of the slice and place into the refrigerator to set for around 3 hours, or overnight if possible.
- Once set, use a clean, sharp knife to cut the slice into pieces of desired size. Enjoy!

Hi, I made this recipe and looooooved it but the Australian sun isn’t very forgiving and the icing was very melted.
Do you think i could make these into a truffle ball and coat in white chocolate, rather than the icing? Could i mix white chocolate and lemon to enhance the lemon flavour?
Thanks so much 🙂
Hi Helen! I’m so happy to hear that you loved the recipe. I would highly recommend keeping the slice in the fridge until ready to serve- you can also make the icing a little thicker if you choose by adding some extra icing sugar. I haven’t tried making the slice into truffle balls in the way you’ve described, but you can certainly give it a try! The mixture should be pressed into firm balls and set to hold them together. Melted white chocolate and lemon zest would be a lovely addition 🙂
This Lemon Coconut Slice is so good! I love it’s lemony-ness. So often Lemon slice tastes like biscuits and icing, but this one is so deliciously lemony. My family were very vocal that this was not to be shared by my colleagues.
Thank you Helen, you have made my day! I’m so happy to hear this. I love the extra lemony-ness of this one too. And I don’t blame you for not taking it to work! Thanks for taking the time to comment, it’s really appreciated 🙂
I love the lemon – coconut combination, and the fact that these are no bake is a definite winner! My son will love them!
Thanks Robyn! No bake treats are so easy- your son will have fun helping with this one too!
I’m in heaven – these are/were delicious!!! Great easy step by step recipe

Ohhh these look yummy, I haven’t had lemon slice in years. And so quick and easy to put together. Will have to make this as soon as we get more lemons from our tree.
It’s certainly an old-fashioned favourite! It’s one of my go-to recipes every time we have lemons on our tree! I hope you enjoy it 😀
Oh these looks So delicious and so easy to make! I love the lemon/coconut combo si I definitely need to give these a try!
Lemon and coconut is one of my favourite combos! And the old-fashioned lemon slice is a perfect way to use them. I hope you enjoy!
This slice reminds me of school bake sales as a kid! I love how simple slices are to prepare and that lemon icing looks divine – although I do love the idea of adding passion fruit as another option!
Hi Sally! It’s such a super simple slice to make in a hurry- and I remember them from bake sales too!
