Recipe testing

I just love slices and no bake slices are even better! Whether it’s a chocolate-y Mars Bar Slice or a tangy wake-up call like my Easy Passionfruit Slice, these simple recipes are some of the best.

They’re perfect to share for morning or afternoon tea or even for a low-key birthday party. And this buttery Lemon Slice recipe ticks all the boxes.

Made with crushed store bought biscuits, fistfuls of coconut, and plenty of fresh lemon juice and lemon zest, it’s bright and flavourful.

Then comes a little butter and oodles of sweetened condensed milk to make it both buttery and moreish. You’re welcome!

The final touch is a thin layer of lemon icing which takes the lemon flavour over-the-top in the best kind of way.

Ingredients

You only need a handful of basic ingredients, six in total, to make my easy Lemon Slice. Let’s take a look:

• Storebought biscuits: Any plain, sweet storebought cookies or biscuits should work. I use Digestives for the biscuit base, but Graham Crackers, Arnotts Marie or Rich Tea biscuits will work too. You’ll need to crush the biscuits into fine crumbs. A food processor is a quick way to do this but if you don’t have one, you can put them in a sandwich or zip lock bag and give them a good bash with a rolling pin – it’s effective and a little therapeutic.
• Desiccated coconut: I recommend using unsweetened coconut. Desiccated coconut is nice and fine so lends itself well to this slice, but shredded coconut will also work.
• Lemons: You’ll need both fresh lemon juice and zest for this recipe for maximum flavour.
• Butter: If you use unsalted butter, add a pinch of salt to the dry ingredients.
• Sweetened condensed milk: I tested this recipe with both sweetened condensed milk and skim sweetened condensed milk – both worked. I used Nestle brand. Don’t use evaporated milk – it’s not the same.
• Icing sugar: Or powdered sugar. This is used to make the two-ingredient lemon glaze icing. Make sure your sugar is sifted for a smooth icing. Don’t use caster sugar or regular sugar – only icing or powdered sugar will work here.

How to make Lemon Slice

This is a really quick and easy recipe. You don’t need an electric mixer and it’s completely no bake. Here’s a summary of how to make it, with the full instructions listed in the recipe card below.

1. In a large mixing bowl, add crushed biscuits, coconut and fresh lemon zest (photo 1).
2. Give dry ingredients a quick stir (photo 2).
3. Add sweetened condensed milk, melted butter and fresh lemon juice (photo 3).
4. Stir until crumbs are fully coated – the mixture should resemble wet sand (photo 4).
5. Transfer mixture to prepared pan and press down using the back of a dessert spoon into one even layer (photo 5). Place in the fridge to firm up slightly.
6. Stir together icing sugar and lemon juice. Drizzle over lemon icing and spread out into one even layer (photo 6). Place in the fridge to set.
7. Sprinkle slice with extra lemon zest. Slice into squares to serve.

Biscuits: Any sweet plain store bought biscuits will work. I’ve used Digestive biscuits but graham crackers, Arnotts Marie or Rich Tea biscuits would also be fine. You’ll need to crush the store bought biscuits. If you don’t have a food processor, you can put them in a sandwich or zip lock bag and give them a good bash with a rolling pin – it’s effective and a little therapeutic. 

Coconut: I recommend using unsweetened coconut. Desiccated coconut is nice and fine so lends itself well to this slice, but shredded coconut will also work. 

Sweetened condensed milk: I tested this recipe with both sweetened condensed milk and skim sweetened condensed milk – both worked. I used Nestle brand. Don’t use evaporated milk – it’s not the same.

Storage: Keep Lemon Slice in the fridge in an airtight container.
