Make this Easy Chocolate Coconut Slice in no time at all – simply melt & mix! Conventional and Thermomix instructions included.
A few weeks ago, one of of my best friends had her second baby. Before I went to visit for lots of bubba cuddles, I asked if there was anything she wanted me to bring over… her answer – chocolate! You can see why we’re friends! Anyway, I thought I’d go one better and make one of my favourite chocolate slices. If you’ve never made this Easy Chocolate Coconut Slice before, then you are really, really missing out!!
This was actually one of the very first recipes I ever put on the blog, but after two years, I thought it was time it had an update, or a foodie makeover… because every good recipe needs a makeover now and then. The thing I love the most about this slice is that you probably have all of the ingredients in your cupboard and fridge – which means no extra trips to the supermarket (am I the only person who seems to live in the supermarket?).
It’s also the simplest thing ever. You literally just ‘melt and mix’ the ingredients in the base, pop it into the oven, and then spread the icing over the slice. I like to spread my icing on while the slice is still warm, in fact when it’s just out of the oven, because the heat of the base makes it so easy to spread. As you can see by the pictures, this recipe makes quite a lot of icing, so leave a bit off if you’d rather a thinner layer (but come on… it’s icing and who on earth can say no to thick icing?).
So whether you’re making this slice for yourself, as a great little lunchbox filler, or for a friend who’s just had a gorgeous little bub, you really can’t beat this easy chocolate coconut slice. Puh-leeeeze make it, make it, make it!!! Trust me on this one – there’s simply nothing better!

Oh Sammie – as always, you’re far too kind. xx
I just made the chocolate slice.
Very easy and very yummy and my friends kids loved it.
Thank you for the making my pants fit again. They were a little loose and they doctor did say the other day that there was far to much blood in my cholesterol system anyway.
But will soldier on…cant waste it.
Regards,
Your new Australian cooking friend
Anthony
Hahaha I love that!! So glad your pants now fit!
Sent these with my friend who works in a hospital. I added raspberries (chopped) and they were awesome.
I am moving to Melbourne for work and they have asked me to send them care packages….lol. live your work
Anthony
That’s awesome! Thanks so much!
Yum! I’d make that today except I’d have to go and buy the ingredients, and can’t be bothered!! Looks great tho!!
Oh no!! Maybe tomorrow then Lydia!
This slice looks magical Lucy! Perfect for a sweet tooth like me. And those perfect edges – swoon!
Thank you so much Jess. Hahaha yes I love that you are slice cutting obsessed too!
Yummy! Might have to try this!
Oh definitely do Jody – you and your kids will love it!
You are amazing! This slice looks so yummy. Look at those perfectly cut pieces again! Agree that you are the Queen of Slice!
Oh thank you so much Cindy – you’re so lovely.
Oh it looks so good Lucy…..and thick icing is the best!! I will definitely have to try this one so thank you !!
#TeamMM
Haha yes thick icing is definitely the best!
My mum used to make this slice (with slight variations) when I was going up. LOVE LOVE LOVE. Another one to add to the long list of Bake Play Smile recipes to make!
Yes definitely! I know – I can’t remember the number of times we made this!
This looks so yummy, my slice never looks as photogenic as yours!
Oh yes they do!! Your’s are great Shari!
Oh, my favourite flavours! Your slice looks sensational.
Thanks lovely xx
Yummo! I love the look of this – and I think I may actually be able to make a vegan version if I sub the butter and eggs… 😀
Oh that’s a great idea!
Hi, just made these this morning – not sure if they have turned out right though as my kids have pinched my measuring cups, so I had to go online to do weight conversions! Is it supposed to have a brownie like texture? Also, what is 2tlb of water? I assumed it to be 2 tablespoons, but this wasn’t enough so added a good bit more and even then my icing was very thick and not very spreadable! Thanks!
Hehehe oh thats very funny! Lol yes it’s meant to be 2tbs – thanks for picking up my typo! I’ll go and change it now. The icing can depend on the brand of icing sugar/icing mixture you use and so yes, sometimes you do need to add a bit more. 🙂
Great! I’m in the UK, so def using different brands they tasted delicious though!
Fantastic to hear Mel!
Mmmm, these do look easy and very, very yummy. Thank you. #MummyMondays
Oh definitely – couldn’t be easier!
I love a classic chocolate and coconut slice! This definitely reminds me of my childhood.. I must make this recipe soon!
Oh me too! It’s just the best!!
I do just happen to have all those ingredients in the fridge/cupboard! Going to have to whip up a batch asap 😉
this slice makes me feel quite nostalgic because my mum made it regularly when I was a kid – lovely to see it here looking so beautiful
Oh mine too!
Yum!! I make a similar slice and it’s always a winner 🙂 I feel some baking maybe in the cards today YUM! I’ve pinned this for later #fabulousfoodiefriday X
Anything with a chocolate coconut combo is a winner in my book, yum!
Absolutely 🙂
This brings back memories of what my mum used to make when I was a kid. So yummy for afternoon tea!
Yes exactly Eva!
These coconut slices look delicious. Could you please tell me what SR Flour is? Thanks!
Hi Dawn, SR flour is self raising flour 🙂
Yet another amazing recipe from your blog! Thank you so much once again for sharing, I am currently preparing for my second little baby’s arrival, hence nesting and baking up a storm! You’re recipes are honestly some of the best and easiest to make. Thank you!
Hi Honi, oh thank you so much! You are just so sweet. You sound so organised! Congrats on your pregnancy!! xx
~ Uh oh… My base turned out REALLY hard and crunchy like a biscuit! Eep! Hmmm… I guess I have two choices: 1) Make another batch and cook at a lower temp (maybe 150C for 15-20min); 2) Leave my current batch as is and label it “crunchy coconut slice). Haha, oh dear… 😉
Hmm that’s so strange!!! I would say that lowering your oven will definitely help! Hehehe or you could just go with crunchy!
Hi, can this be frozen – I’m looking for tray bakes that I can make ahead and freeze for a church event next month and this looks great
Yep definitely!
Hello. I would love to bake this chocolate coconut combo. Would you please let me know the measurements in grams of the following. I have tried on internet searches for conversion but found different measurements.
Thank you
1 cup firmly packed brown sugar
½ cup plain flour
⅓ cup SR Flour
¼ cup cocoa powder
½ cup desiccated coconut
ICING:
1½ cups icing sugar
¼ cup cocoa powder
Hi there!!
I think this link will help you not only with that particular recipe, but any in general!

An old post but my ten year old made this today, all I had to do was melt the butter in the microwave. Making her own lunchbox treat- definitely a winner.
Fantastic!!!! I LOVE hearing about kids in the kitchen! Your daughter sounds like quite the mini MasterChef!
OMG seriously the best Choc Slice I have ever made!! And Easy!! Kids are totally in love with it – and have asked for it to made again for a birthday party on the weekend!!! Too good!
So happy to hear that! Thank you!
Oh wow! Thank you so much!!! I’m thrilled that you liked it!!
Just letting you know Lucy that my slice turned out Amazing! The texture was kind of like a fudge-y cake, moist, but not wet, and definitely not crumbly… And the taste was better than I expected – almost like chocolate-caramel, Yum! We started with a hot knife (for cutting) but that caused the icing to melt and stick to the knife, so for us it was a much cleaner cut with a cold knife. Very hard to just have one, or two or…. Thanks for sharing this recipe.
Hi Lucy, this looks amazing, I am going to try this tomororrow! I was wondering your opinion of adding cherries to this? Do you think I could puree them or add whole? And if so, would I need to add sweetener to the cherries first as I still want it to be super chocolately rather than tart. So many questions – sorry! Might just stick to the original 😉 Thank you!
Yes definitely!!!! I would add them whole or perhaps cut them in half – they should be sweet enough! 🙂
Definitely will be making this one
Enjoy!!! I think you’ll love it!
Just Made it fantastic simple tasty
Thanks Paula
Hi can the egg be replaced with something else? Due to allergy
Hi Michelle, you could try making ‘flax eggs’?? xx
http://minimalistbaker.com/how-to-make-a-flax-egg/
Just made these because I felt like something sweet at night! Sooo good. Like delicious chocolatey coconut brownie slices of pure goodness. My mum ate 3 pieces!! Hahaha. Speaks for itself.
Hahaha I love that!!! Good on your Mum!! xx
HI
I just googled slices to make ahead and freeze and came across your site of 15 freezable slices.
I am wanting to make this chocolate slice and freeze but would I ice it and then freeze or freeze then ice after defrosting?
Thank you and love your site and gourgeous photos.
Dolly
Yes you can absolutely ice it before freezing! Thank you so much for your lovely comment xx
HI Lucy
i’m making this today for kids lunchboxes – thank you ! Could you please tell me if I could freeze this ?? I like to be able to freeze lunch box stuff so I can just pull out what they want that day for their lunch box.
Many thanks Jen
You definitely can freeze it!!! Also check out this post (it might help in the future too): https://bakeplaysmile.com/15-freezer-friendly-slices-best-ones/
Hi i just made them for a 3rd bday tomorrow and just wanted to know how are they best kept.
Thanx
Hi Laura, just in an airtight container at room temperature. 🙂
Thanks for the tip & awesome recipe.
Hi, I’ve all the ingredients on hand for this and it looks like a great recipe! But the biggest pan I’ve got is a 9×13 inches. So can I divide the recipe in half and make it?!
That will be fine!! It will just be thicker and may need to bake slightly longer. 🙂 xx
Oh my goodness. I had a recipe very similar to this that I used to make a lot. When I got married and moved I lost it and was quite devastated. I am so glad I found your site!!!
Oh yay!!! Enjoy! xx
MMMMMM these sound delicious!!!! my great grandmother once told me that the future would hold your recipe of a beautiful coconut slice. i thought she was a bit funny in the head but turns out she was right. i can travel to outer space and it is the most wonderful place on earth1!! i think i might try making this in space while looking at the stars.
Hahaha oh thats so lovely!! She wounds very wise!
Hi is this the recipe from Treat Yourself Sweeter as she messaged me to let me know that she gave u her recipes and im after her recipes for her chocolate coconut slice p;ease if u can let me know Id be forever grateful.
Cheers
Hi Sonya, no this is one of mine sorry xx
Can these be frozen? And thawed for lunchboxes as needed?
Absolutely!!
Mine was like a fudgey brownie. Sooo good! We had it for morning tea – it didn’t last! Thanks for the recipe.
Yay!! So glad you liked it Kirsten!! xx
