I first published this recipe in April 2014.
A few weeks ago in my Thermofunkies Members facebook group we were talking about this recipe.
Jenene said this also works with zucchini and carrot OR just 200g carrots! Jenene also reduces the sugar to 180g. Emma another member, said she likes to add a tsp of cardamom too!
I’d love to hear if you have made any tweaks to it. :)
This is the most amazing cake. 23 seconds in the Thermomix! There is no need to squeeze the moisture out of the zucchini and as a benefit to this it keeps the cake so moist for days and days. I love the thought of having hidden vegetables in cakes, as then I don’t feel guilty for indulging! :) This cake also is sensational even without the cream cheese frosting. I took the cake to work and it was demolished in literally seconds and everyone wanted the recipe for it!

Magda says
This is one of my favourite recipes, I make it so often. Beautiful soft texture and it’s so easy and quick. I have substituted the zucchini with pear and it was great too.
thermofun says
Thank you so much Magda! I can’t wait to try it with pear now!
Lisa says
Yum! I made this and it was delicious!
I only used 100 grams of sugar. And I used half oat milk/ half coconut oil.
thermofun says
Thanks Lisa – love your tweaks too! :)
Happy thermomixer says
This is AMAZING! My fiancé HATES zucchini so I snuck this in and he LOVED it! (Wasn’t too chuffed about being tricked ;) ). I gave some to friends and neighbors and they all loved it too! I’m going to try it again but cut back on the sugar so it’s not so bad for you!
Natalie Ann CAMPBELL says
Yum!! This is my go to zucchini cake. Today I added 30gms of cacao powder and the zest of an orange instead of lemon.
thermofun says
Yum sounds great Natalie :)
Natasha says
Love this recipe! Our daughter is allergic to eggs, so i use 3 tblsp of vinegar, and 2 tbls extra oil instead! I also halve the sugar and add 30g organic cacao powder to make ‘chocolate muffins’ my 3 kids devour them!!!! Sometimes ill peel them and add white choc chips (instead of cacao powder), for something different! They really are a no fail cake or muffin recipe!!
thermofun says
Thank you Natasha, fabulous to hear the vinegar and extra oil subs well too! Great to hear re the cacao too – I’ve also done that and it worded a treat!
Joeanne Hanlon says
Just wondering if you can peel the zucchini? As my husband is extremely fussy and if he seen green specks in it he wouldn’t even try it.
thermofun says
Yes you can Joeanne. :)
shaun says
Hi Leonie
thank you so much for this recipe I always struggle with cakes but I have made this 6 times and it turns out every time.I am going to do some mods and will let you know how it goes
Shaun E
thermofun says
Great to hear Shaun – I am sure you will love all the other cakes as well :D Yes please to the mods :D
Marion says
I made this with a lemon drizzle icing as I didn’t have room in the fridge with cream cheese frosting. It was delicious and enjoyed by all.
thermofun says
Thanks Marion – I love the sound of the lemon drizzle icing too! :)
Patricia McGrath says
This is a super recipe!! I added 50g cocoa powder and substituted orange for lemon zest – and voila! – a delicious moist chocolate cake that doesn’t crumble when you cut it. Great recipe. This will be my go to chocolate slice now
thermofun says
Thanks Patricia, I love your tweaks! I will certainly look forward to trying! :)
Juliet says
Is there a way this can be done with a little less sugar ?
thermofun says
Juliet, I haven’t made it with less sugar but many others have and have said it turned out great. I think it will end up being personal preference to find what works for your family.
SusanE says
I made this today but added lime. I replaced the lemon and vanilla in the batter with the zest and juice of 1 lime, and then replaced vanilla in the icing with the zest of 1 lime and the juice of 1/2 lime. It is really good!
Kylie Berryman says
I make this cake almost weekly, great in the lunch box (without frosting), also make it into cupcakes. I reduce the sugar by 100gms and sometimes replace oil with same amount of applesauce, works well every time. Today I made it with Gluten Free flour (250gm) and it turned out amazing. Until I tried this recipe I could not bake cakes and I was well known for my cake flops, now whenever I have to make a cake to take I trot this baby out and sit back and enjoy the yums! Thanks Leonie.
thermofun says
Thanks Kylie – great to know it is just as good with gluten free flour and less sugar too! Great idea re the apple sauce too, I will have to try that! :)
cecilia says
Hi
I made this and couldn’t to taste it, it looked amazing but it took longer for it to cook mine took an extra 30mins in the oven and once it was ready to eat all i could taste was the bicarb in it and i followed the instructions and i made sure i only put 2 tsp of bicarb in, its eatable but everyone says there is a funny taste to it…. i used a zucchini from my dads garden that is light green in colour and though that this may have been the problem with the longer cooking time as it may have been more watery than the normal dark green zucchini… did anyone else have trouble with the taste of bicarb? luck i taste tested it on my family before i took it to my friends house.
thermofun says
oh no Cecilia :( To be honest you are the first I’ve heard say that for this particular recipe. Hopefully others may have some ideas for you as to why this may have happened.
Lisa says
Hi, thanks for this recipe. Delicious cake and gorgeous texture! I used a large baking tin as per your measurements, but it has come out pretty flat, so I will use a smaller square tin next time. I also reduced the sugar to about 90g. Thanks again.
Tara says
I made this gf and dairy free using Tofutti cream cheese and Nuttlex for the icing. It took a little longer than to cook, however it was very moist and delicious!
thermofun says
Thanks Tara great to know. :)
Jenny Sullivan says
Well silly me ordered 2 x 500g packets of zucchini’s on my coles online order instead of just 2, this week oops. So I went straight to this recipe to use up some, I think I might make the other one as well with the pistachio’s and lime frosting, as I definitely have enough Zucchini’s. Thanks Leonie for yet another amazing cake recipe so yummy and moist.
thermofun says
lol that’s rather funny Jenny about your order! :)
[email protected] says
sooooo amazing made this last week and everyone loved it and one of our station hands asked for it for his birthday :) So moist you don’t need the icing but the icing is lick your lips delicious.
thermofun says
Thanks! It’s certainly a keeper! :)
Jenene says
That should say 100g coconut sugar, sorry!
thermofun says
Thank you :)
Jenene says
This cake is so versatile. I made it AGAIN today with g coconut sugar only as thats all i had. Turned out perfectly!
thermofun says
That’s great to know about the coconut sugar Jenene. thanks :)
Kirsten says
I added frozen raspberries and it was delicious!!
thermofun says
oh wow what a fabulous idea Kirsten. thank you for sharing. :) Is there any chance you can recall how many grams you added?
Kirsten says
Hi I think it was about 1/2 cup frozen raspberries at the very end and carefully stirred so they didn’t break up. The cake got many compliments at the work morning tea – thanks
thermofun says
Many thanks Kirsten. I and I’m sure many others will look forward to trying it with raspberries. Thanks for letting us know how much you used. :)
Tara says
Amazing as usual! Have made this cake soooo many times, and always turns out a charm.
Tomorrow it will be going to a bake sale to raise some money for my daughters dance club, and its always the first sold!
Thanks Leonie!
thermofun says
Thank you Tara. I hope the bake sale went well today. :)
Jules says
very nice cake. I reduced the sugar though to 100grams
Shell hall says
Can anyone help I am cooking this now it’s been in the oven for 35 min and still completely wobbly in the middle. I have checked the temp and it is right.
thermofun says
Sorry Shell just saw this now. It’s the weirdest cake as some do seem to take a lot longer than others.
Lisa Roberton says
okay, given the high praise I just read I will give this a go as have always been a bit hesitant in making cake with veggies – just a me thing…….. Stay tuned.
thermofun says
oh I am TOTALLY with you on that Lisa re veggies in cakes!! lol! Seriously though this one you will not know! I can’t wait to hear what you think! :)
Tricia casey says
I tried this using coconut oil and I put a full punnet of fresh blueberries on the bottom of the cake before placing in the cake mixture. Served it with the orange custard instead of the cream cheese icing. Made a great dessert. What was left still made a great lunch box cake without the icing. Thank you for this lovely versitile recipe
thermofun says
Wow Tricia what an awesome idea with the fresh blueberries on the bottom – thanks for letting us know. :)
Rhiannon says
I am yet to receive my TM, and desperately want to try this recipe… Would I just bung it all in the good ole food processor??
thermofun says
Yes that should be fine Rhiannon :)
Chrissie DiCarlo says
Hi tested this out the other day, in the cake i used coconut sugar instead of raw sugar & i used half coconut flour & half wholemeal plain flour. I found that the amount of sugar in the icing was way too much(to sweet) so i will lessen that next time, as i didnt have any coconut sugar left i used raw sugar in the icing, i added more philly cheese & butter to try & unsweeten it a little, but must say the cake was eaten up within a couple of days, we all loved it, thank you for recipe. Next time I make it, I am planning on using all coconut flour & coconut sugar in both the cake & icing, fingers crossed it works.
thermofun says
Chrissie I’ll be very interested to know how it goes with coconut flour and coconut sugar. :)
Twissty says
hi there am testing this recipe with zucchini and pumpkin, the batter tastes so that’s a good sign
thermofun says
oh I’ll be dying to hear how it goes with pumpkin! :)
Twisty says
Was really yummy with pumpkin and zucchini mix! We made them into patty cake sizes for lunch boxes and used Betty Crocker vanilla icing as my kids are dairy free. Delicious! About to make more
thermofun says
oh great to hear it works with pumpkin. :)
Kez says
i’ve just made this cake it is baking as we speak, I used rice bran oil as all had left in cupboard (didn’t see the comments re coconut oil – will use that next time) but I added Black Chia Seeds, LSA & Cocao be interesting to see how it turns out as I didn’t measure just a couple of tsp of each.
Chrissie DiCarlo says
Hi I was just wondering if I could use wholemeal plain flour? Also was wondering why do you use the plain flour & baking powder if this equals self raising flour, why not just use self raising flour?
thermofun says
Hi Chrissie,
the usual reason for using plain flour plus baking soda is that allows you to control the ratio of flour to raising agent. And some countries don’t have SR flour so specifying plain plus baking soda makes it more widely useful. In this recipe the ration is about the same as SR flour, so it should be OK, you would still need the bicarb soda as well.
I haven’t tried it with wholemeal flour but I would be keen to hear how it goes.
Here’s a great article on plain flour vs SR flour:

JANET LAVER says
Everyone has loved this cake.
It freezes well, and about to make them into cupcakes to take with me next week for my grand-children :-)
Missyann says
Very very yummy! It took more than 60 minutes for the cake to cook but it’s the first time I’ve cooked a cake in my oven so I’m not sure if it needs longer or if my ovens a bit slow. It’s is such a moist but springy cake. I have another zucchini in my fridge so I think I might make another one tomorrow for my dad. Thanks for the recipe.
Vicki says
Hi I just tried this!! The bad news was my oven died as when I went to check the oven just wasn’t hot enough and the cake just wasn’t cooking! Will have to try this again!
thermofun says
oh no that is such a shame Vicki re your oven. :(
Alice Shaw says
I recently made this cake. Used coconut oil as I noticed another commenter had done and it turned out brilliantly. The kids ate it without me even icing it. High praise indeed :-)
thermofun says
Thanks Alice,- it is amazing that it is so moist isn’t it?! I often make it without icing it! :)
Silvana says
Hi just wondering if there are any sugar substitutes that have been used for this recipe please. I want to try it but trying to cut out sugar :) thanks
thermofun says
Sorry Silvana I haven’t heard of any yet for this cake. I have certainly reduced the sugar successfully so you could try that and see how you go.
Silvana says
Thanks I will try making it tonight with a substitute and will let you know how I go.
Kelly says
I can’t get over how light and moist this cake is! It really is superb! I do have a question, possibly a silly one….I’m a 2 week old Thermomix newbie and have had more thank my fair share of baking flops! What is the reason to have baking soda and powder in the recipe? Is it possible to cut back on the baking soda? I swear I can taste it. My hubby thinks I’m crazy! Won’t stop me from having a second piece, though! I better hurry..everyone loves it! :) it really is fantastic!
thermofun says
yes it is really moist isn’t it Kelly. :) The baking soda adds to the lightness of the cake, but you can leave it out if you wish. It just won’t be so light. If you can taste it, perhaps halve the quantity next time you make it.
The baking powder added to the plain flour works as a raising agent – that’s how we can make self raising flour if we have run out. (2 tsp baking powder to each cup of plain flour = self raising flour!)
Deb says
Great recipe. I didn’t have enough zucchini so used carrott and zucchini and it tastes so good and was so simple…..not sure it will last long enough to put the frosting on it
thermofun says
Great idea with the carrot Deb. I made this the other day and only had 2 eggs and not even 190g in sugar and it still worked and was yum! Certainly a NO FAIL recipe for a cake no matter what we do I’m thinkin’! :)
Lise says
I used a little more oil and added some water, which then made the batter quite runny so added about 50g more flour to thicken it up a little. Was very yummy, though my cake was decidedly green!
Lise says
Looks divine! About to attempt an eggless version…!
thermofun says
oh I’d love to know how it goes with no eggs Lise – what will you sub them with?
Nadia says
Am also going to attempt an eggless version… Have recently been subbing egg with mashed banana so will see how it goes! Might put in some ‘chia egg’ too. It’s also going to have to be gf…can’t wait to taste it !
thermofun says
oh Nadia I will be very interested to hear how it goes with no eggs. :)
Nadia says
It was fantastic! The banana added a nice flavour. Although I think next time I will use 1/2 oil and 1/2 milk (oat, we’re also dairy free) because I found it a little too greasy for my taste.
Nicky Jellesma says
Hi. I made this with coconut oil and it taste amazing. Thank you. At this time of year always looking for ways to use up zucchini.
thermofun says
Thanks Nicky – yes it is amazing isn’t it! And healthy too with the zucchini!! lol
Ana says
Hi I made this today and my toddler loved it kept asking for more. The sugar still had bits of it on the icing I don’t know what a did wrong . I put some orange on the icing it was really nice. Thanks for sharing its our family favourite now.
