To make dairy free lemon slice you’ll need:
- 205g (2 cups/7oz) plain milk/egg/nut/soy/gluten free cookies
- 90g (1 cup) desiccated coconut
- 160g (1/2 can) non-dairy condensed milk
- 2 Tablespoons non-dairy spread (eg Nuttelex or similar), melted
- grated rind of one fresh lemon
- 3 Tablespoon fresh lemon juice (1 for the slice, 2 for the icing)
- 1 1/2 cups icing sugar (powdered sugar)
- extra desiccated coconut for decoration
Vegan and allergy-friendly plain biscuits or cookies
We used an arrowroot biscuit in this recipe, but you can use any type of plain crunchy cookie that is suitable for your allergies. The Woolworths brand Free From arrowroot biscuits we used are free from gluten, milk, eggs, nuts and soy, but if you don’t need to avoid soy the Leda arrowroot biscuits are very similar.
Other options include Enjoy Life vanilla honey graham cookies, Eskal vanilla tea biscuits (contain soy) or Schar digestives (contain soy). Make sure you check the ingredient labelling and any precautionary allergen statements carefully to choose something safe for you.
Desiccated Coconut
Make sure you use desiccated coconut and don’t try to substitute shredded coconut or coconut flakes. Desiccated coconut is a finely grated, dry coconut product. I usually buy McKenzies desiccated coconut. Don’t Shredded coconut and coconut flakes are too moist and don’t give the same texture.
Dairy free condensed milk
For this dairy free lemon slice, we used Pandaoroo sweetened condensed coconut milk. Another great option is Nestle Plant Based Condensed Milk Alternative (with oat milk). Both of these are available at our local supermarket.
Dairy free condensed milk comes in a smaller can than traditional condensed milk. For this recipe we only use half a can, so if you want to use the whole can just make double quantity!
If you can’t source a suitable non-dairy condensed milk, you can always make your own. For a vegan sweetened condensed milk, reduce about 650ml of your non-dairy milk with 50g of sugar in a saucepan over low heat. You can also add a dash of vanilla.

Method
Grease and line a 20x20cm (8×8 inch) baking pan with non-stick baking paper, allowing the paper to sit above the pan edge on 2 sides.
Crush the biscuits to make a fine crumb. You can do this in a food processor, or when I don’t feel like washing the whole processor I like to use my Bamix stick blender and the processor attachment. If you don’t have either, just put the biscuits in a bag and crush with a rolling pan.
Combine the dry ingredients – the crushed biscuits and the desiccated coconut – in a large mixing bowl using a wooden spoon. Add the grated lemon rind and mix well.
Melt the non dairy spread in a small saucepan (or heat for 30second on medium heat in the microwave).
Make a well in the dry ingredients and add the wet ingredients – the condensed coconut milk, 1 Tablespoon of lemon juice and melted Nuttelex. Mix these ingredients until well-combined. The mixture should form a ball.
Press the lemon slice mixture into the prepared pan to create an even layer. Use the back of a spoon or spatula to press down until the top is smooth and even.
Chill the slice in the fridge for 1/2 hour.
Make the lemon icing by mixing icing sugar and the remaining 2 Tablespoons of lemon juice. The consistency of the icing should be quite thick but spreadable. (You can add more icing sugar or lemon juice as required to get the right consistency).
Remove the prepared slice from the fridge, spread lemon icing over the top and sprinkle with extra desiccated coconut. Return to the fridge until the icing is set.
Once firm, cut into small pieces with a sharp knife.
This recipe makes about 24 pieces of lemon slice. Prepared slice will keep in the fridge for about a week.

These lemon slices are so perfect and I appreciate that they’re vegan and nut free. Definitely going to make these for the toddler more often!
They are going to be on my list for this weekend baking!
Love this recipe especially as they cater to so many dietary requirements and still taste amazing! Accidentally adding too much lemon juice in the base turned out amazing for my lemon loving family and was more of a dense and sticky bar YUM! Do we know if these freeze well?
Hi Steph. So glad to hear you enjoyed this recipe! Yes, I have frozen this lemon since with great success. I like to put some non stick baking paper between the slices before freezing to make sure they don’t stick together. Hope that helps 🙂
Quantities should be increased for the 20cm x 20cm pan. For the slice to look as pictured, I would double quantities of everything. Tastes lovely but looks quite thin.
Thanks Katie. The recipe quantity does make a reasonably thin slice as it’s quite sweet, but if you prefer a thicker version double quantity is a great idea. Glad you enjoyed it!
Looking forward to trying these. One question, will the icing melt if left out for an afternoon? Or will it keep stable?
Hi Anna. The icing doesn’t have any butter, so it won’t melt like buttercream does, but I expect it would get soft quickly if left out too long. Especially on a warm day. You could try making it thicker by adding more icing sugar, or even adding a little starch (corn flour) to increase the stability if that’s suitable for your allergies.
