An easy, no-bake slice made from crushed biscuits combined with butter, sweetened condensed milk, lemon juice and zest and coconut, topped with a sweet lemon icing. This slice is great for school lunches or afternoon tea.

The beauty of a biscuit-base, no-bake slice is that you can't really muck it up (please don't try and prove me wrong). There's no oven involved which means you can't over or under bake the base. You simply melt the butter, crush the bikkies, mix the other ingredients in and press into the tin. Spread the icing and voilà, you have a beautiful No Bake Lemon Slice.
This is not unlike a 'hedgehog slice' if you're familiar with that term. I have an excellent recipe called Chocolate Fish Slice which also uses this method.

Ingredient notes:

- Biscuits: Any type of plain biscuits will work in this recipe. From Arrowroots to Maries, to Super Wines or even Malt biscuits if you like. Gluten free arrowroots will also work.
- Sweetened Condensed Milk: This is one of those niche baking ingredients that I try and keep stocked in the cupboard at all times. Own Brand versions will work just as well and are often cheaper.
- Butter: You may have noticed that I pretty much always use salted butter in my making recipes. I love the salty flavour it adds to sweet slices.

Step by step instructions:
Line a slice tray 30 cm x 20 cm with baking paper. In a large glass bowl, heat the butter in the microwave for 40 seconds until melted. Stir in the condensed milk. Place the biscuits in a food processor, one packet at a time. Add the desiccated coconut with the first packet and blitz until fine crumbs form. For the second packet, blitz but leave larger chunks.


Combine the crushed biscuits and coconut with the butter and condensed milk mixture in the bowl. Add the lemon zest and juice and mix until well combined.


Press into the lined baking tray, flattening it down evenly and spreading out to the edges. Place in the fridge while you prepare the icing.


Add the icing ingredients to a bowl then whisk together until smooth. Spread the icing evenly over the base.


Place the tray in the fridge and let it set for 3+ hours or overnight.


Once set, cut into pieces and store in an airtight container in the fridge for up to a week.

Hi Vanya, This looks delicious! Do you have any suggestions as a replacement for the coconut? I have a family member who doesn't like it.
VJ cooks says
You could leave it out and reduce the butter to 100g. Or, try substituting it for 1/3 cup of oats. I haven't tested it these ways though.
Wendy says
Hi there can you leave out the coconut In this recipe please ?

Su says
Another winning recipe. So yum and zesty. My mum made this and I only got a taste test before she took it to her church and it was gone. She made it without the coconut. I got her to make it again with coconut and it was also really, really good.
VJ cooks says
That's awesome. Thanks for the feedback, Su 🙂
Sam says

Kim Reilly says

Corina says
Hi- lovely recipe, as always!
If i wanted to add a bit of white chocolate, could I add white chocolate chips to the base? Rather than meting chocolate which doesn’t always love lemon?
Thanks!
VJ cooks says
Sure thing.
Rosie says
Made this with Krispie biscuits, and fresh limes instead of lemon. Absolutely delicious!
VJ cooks says
Oh that's great to know. Thanks for the feedback, Rosie.
Helen says

Bonnie says
I got compliments on this. It tastes like the one my mother used to make, but maybe my memories are a little sweeter there for other reasons. The ratios are all well balanced. Thanks from Pukekohe!
VJ cooks says
