Expert Tips

  • Crush biscuits to a fine crumb: The easiest way is in a food processor. If there are chunks of biscuits, they will not stick properly in the base layer.
  • Don’t have a food processor? Simply place the biscuits into a large zip-lock bag, seal it closed and with a rolling pin, roll it over the biscuits until they’re finely crushed.
  • Press the base into the tin with your hands: This will ensure you create an even base layer.
  • Spread lemon icing out with a spatula: Using a rubber spatula, it’s easier to spread the icing all the way to the edges as it’s thick.

Do I have to use gluten-free biscuits?

No, you can use plain Marie Biscuits, plain Digestive Biscuits, or any plain sweet biscuit for this no-bake lemon coconut slice recipe. 

Can I make this lemon slice ahead of time?

Absolutely! Prepare it a day or two in advance and store it in the refrigerator. Just make sure to cover it well or place it in an airtight container to maintain its freshness and prevent it from drying out.

    1. Hi Sue, that’s wonderful to hear you’re enjoying this lemon slice recipe, thanks 🙂 I’ve personally have never tried freezing these before but I don’t see why it wouldn’t work. Just be sure to leave enough time of them to defrost back to room temperature. The base may not freeze solid due to the condensed coconut milk, as it doesn’t freeze sold itself. The frosting however will freeze, again just bring it back down to room temp before serving so both base and topping are the same. Hope that helps! Sam x

      1. These were so good! I also was wondering about making a larger batch to take to events! Thank you for sharing

        1. Hi Kristina! Thrilled to hear you enjoyed the slice! Doubling the recipe should work just fine for a larger batch, use a 9×13 inch rectangular tin instead. If you don’t have a 9×13 inch tin, using two square 9×9 inch tins will also work; just split the doubled mixture evenly between them. Have fun sharing them at your events! Kindest, Sam x

  1. Oh my! This Lemon Sice is amazing!
    I recently made it for my family & it was a huge hit.
    I’ve had to change my diet, no longer able to have wheat or oats, so to find a substitute for the traditional lemon slice & caramel slice, which I’ve been making for 30+ years, is terrific.
    I’ve just made the Caramel Slice today, so hubby will be taste testing it for me in about 2 hours.
    Raw desserts & bliss balls rock (& hubby & the family approves)

    1. Hi Sonia, I’m so happy to hear this! This vegan lemon slice is such a wonderful recipe, especially for you to transition into your new lifestyle. I’m glad it has lived up to your exceptions, especially not being able to enjoy your traditional lemon and caramel slices. How did you go with the caramel slice? Hope you and your family enjoyed the taste of that one also. Thank you so much for sharing this with me, looking forward for you to make more healthy sweet treats! Sam xx

  2. Hi Kim, thanks so much!! It’s definitely delicious 😀 I don’t have a straight substitute for white chocolate but here are a couple of options; you can use vegan dark chocolate as a swap (that’s only if you can find a dairy free and soy free dark chocolate product of course?). Switching to dark chocolate will change the flavour profile of the slice, but any chocolate is good right?! ;). Otherwise you can omit the white chocolate completely and just have a regular frosting recipe, without the addition and flavour of white chocolate. You will just be making a plain frosting which still tastes fantastic and will absolutely work in this recipe. If you choose to omit the white chocolate, you may not need as much icing sugar to thicken the mixture, so just gradually add the powdered sugar until you reach desired creamy frosting consistency. Hope this helps and I hope you enjoy this slice – YUM! xx

  3. Hi Samantha, this recipe looks AMAZING! I cannot wait to try them. Is there anything I can use if I omit the white chocolate in the frosting? I am soy free so unfortunately the only vegan white chocolate I have found contains soy 🙁

  4. how can these be vegan when you are using Arrowroot biscuits, which contain milk and condensed milk?///

    1. Hi Melanie, I use dairy free and egg free arrowroot biscuits which can be found from health food shops. I do state in the recipe that you can use regular arrowroot biscuits or find vegan arrowroot biscuits 🙂

    1. Hi Anna! That’s wonderful to hear! This recipe is one of my family favourites too. Each time we make them for friends, they also devour them! So irresistible and decadent, enjoy! xx

  5. This slice is seriously my fave, ever! And you’ve made it vegan – nice work! I don’t know that I’ve ever come across condensed coconut cream, tho – where did you find it?

    1. Hi Alison! Thanks so much, I’m seriously addicted to it now. I found my condensed coconut milk from my local supermarket which is Woolworths (in Australia), it’s the brand ‘Pandaroo’. This is not my photo but this is what the can looks like http://veganact.org.au/wordpress/wp-content/uploads/2015/08/Pandaroo-Sweet-Condensed-Coconut-Milk.jpg
      You also may be able to find it in an asian grocer? I just did a quick Amazon search and here is what they list: http://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=condensed+coconut+milk

      Hope this helps Alison and i hope you give the slice a try once you find some condensed coconut milk/cream! xx

      1. Tried it today! Absolutely lush – soft and gooey which I like. I used lemon juice instead of almond milk in the frosting for that citrus tang I love so much. xx

        1. Hi Alison, oh good! I’m so glad you enjoyed the slice, you got me craving it now! Definitely sounds like it will be one of your favourite go-to recipes 🙂

  6. It’s so funny, lemon slices were the very first vegan dessert I’ve tried, and I’ve had them on my mind recently, and then BAM, this stunning recipe pops up in my inbox! And gosh it sounds like the perfect mix of zesty lemon, and sweet coconut! You’re a genius!

    1. Thanks so much Rachel! I can read your mind hehe! I’ve already had about 3 slices today and I’m still craving more, yum! Hope you give it a go! xx
