NO BAKE LEMON COCONUT SLICE
Makes: 20-24 squares Difficulty: Easy
EQUIPMENT:
28 x 18 cm Baking tin
INGREDIENTS:
Squares
170g Sweetened Condensed Milk
125g Unsalted butter
250g packet of plain biscuits, finely crushed (e.g Marie, Milk Arrowroot)
1 teaspoon grated Lemon Rind
1 cup Desiccated Coconut
Icing
225g Icing Sugar Mixture (or more, depending on how thick you want the icing)
2-3 tablespoons fresh lemon juice
15g Unsalted Butter, softened
2 tablespoons Desiccated Coconut
METHOD:
In a small saucepan add the condensed milk and butter. Stir together over low heat until the butter has melted and the ingredients are combined. Set aside.
Use a food processor to turn the biscuits into fine crumbs a small batch at a time. If you don’t have a food processor place the biscuits into zip-lock bags and break them down with a heavy rolling pin or meat hammer.
Grab a large bowl and add the crushed biscuits, lemon rind and coconut. Pour in the melted butter and condensed milk mixture. Mix it all together with a spatula until the biscuit crumbs are evenly coated. It might look a bit dry but it’s ok.
With clean hands tip the mixture into the prepared baking tin and firmly press the mixture in place. Leave it in the fridge for 1 hour.
While the slice is in the fridge prepare the icing. Add the icing sugar mixture and softened butter in a medium bowl. Add enough lemon juice to form a smooth spreadable icing.
Remove the slice from the fridge after 1 hour. Spread the icing over the top and sprinkle it with coconut. Allow the frosted slice to set in the fridge.
Once the icing has set, cut the slice into squares. Store the square in the fridge.
BAKING TIPS:
- While Milk Arrowroots are a specific type of biscuit, really any type of plain biscuit will do.
- Store the lemon slice in a container in the fridge

Oooh…these look amazing. Gorgeous!
These look so yummy!!! And i’m with you! I dun really like the heat and never ‘run’ to the beach hehe :) thanks for sharing this recipe! Gonna give this a go soon ~
I make these!! I love how lemony they are. Yours look so pretty and light.
Yeah I like Summer until around February when I’ve had enough and want cosy winter. Although we haven’t had much of a summer up here this year, it’s been worse for you folks down south.
I would love no bake treats every now and again….Quick and easy! And oh so tasty too. Page bookmarked!
These would be perfect in the lunchbox…although I think I’d have to hide them from the man of the house – he’s a bona fide lemon-flavour addict!
Hi Cake Mistress,
I just cut my slice this morning (I made it last night) however the icing was still a bit gooey. Is this normal?
Thanks,
eburger
I am a lemon addict! What a fantastic, no bake slice. Perfect for summer ‘baking’ :)
Very tasty recipe and healthy too.
I nearly always take this into work for “birthday morning-teas”. There’s NEVER any left to squirrel-away for later!! And I have to do this, otherwise I’d sit down & eat the entire tray! I actually make in the large DECOR 4L rectangular plastic container 24 cm x 17cm (approx). It fits into the fridge & then there’s minimal washing up after! I also mix the dessicated coconut (for sprinkling on the icing) 50:50 with shredded coconut – it looks a little fancier!
I love this!
How do I make the icing less sweet and tangy?
