Tried and tested
Not quite a cookie and not quite a cake my copycat of Millie’s Cookies Giant Iced Cookie Cake is a dense, chewy, fluffy cakey delight studded with bitter sweet chocolate chips, iced with vanilla and chocolate buttercream and decorated with rainbow sprinkles. What’s not to love?
This recipe has now been on the blog for a good 18 months and in that time it has received A LOT of attention, which you’ll see in the comments below. A few people have had a few hiccups along the way to cookie cake perfection but I can assure you that this recipe WORKS as many of my readers will happily tell you!
Just see what Sam said earlier this year:
Made this for hubby’s birthday yesterday and it’s amazing! And dangerously moreish!
And the guys at Platter Talk said:
This is one of my favorite copycat recipes; fun and delicious!
I use this recipe for birthdays, anniversaries, an excuse to bring cookies/cake into the office and I’ve even done a heart shaped variation for Valentine’s Day. The possibilities really are endless and you can decorate it any way you choose!
Top tips
If you’re having any trouble with the recipe please don’t hesitate to drop me a comment below. But here are a few helpful hints that should help you along the way to Giant Iced Cookie Cake perfection.
- Check your oven temperature – it’s amazing how much the internal heat can vary from what it says on the dial! I have a handy oven thermometer
so I can be sure what temperature I’m cooking at. They are very cheap but worth their weight in gold!
- Use butter “sticks” or a butter “block” not the spreadable kind from a tub!
- Make sure you use self-raising flour not plain flour or you won’t get any rise and the cake will be super dense.
- Chill the mix before baking on a hot day. If you find the butter has melted and the mix is a little wetter than you expected chill the mix just like you would a cookie dough before putting it in your tin.
so I can be sure what temperature I’m cooking at. They are very cheap but worth their weight in gold!I hope that helps!

The cookie-cake recipe
They key to this recipe is to use a mix of brown and white sugar and to use A LOT of bitter sweet chocolate chips. I find that milk chocolate is just that little bit too sweet. You’ll be grateful for the bitterness that the dark chocolate brings.

Notes
Nutrition
When iced in the same style as Millie’s Cookies you’d never know that this was cooked at home – until you slice into it that is! It is SO close to the Millie’s Cookies Giant Iced Cookie but it is ten times better because its got that extra cakey-ness which takes this from just an oversized cookie to a real show stopper!
Let them eat cake!
Like this? Then you’ll love some of the other cakes and bakes I have on the blog.
Nice! BUT, because i’m a bad person I cant do grams for biscuit making, only do ounces!
Haha that doesn’t make you a bad person 🙂 at least there are some good conversion tools out there! I am forever converting cups to grams. I have cup measures but still prefer grams where possible 🙂
Me too! Looking back over my ‘cooking journey’ made me realise that I prefer ratios over all the diverse weighing systems and I found a great book by Michael Ruhlman called unsurprisingly Ratio. It’s fab give it a read it really helps your cooking.
Oooh sounds interesting I’ll have to see if I can hunt down a copy!
This looks amazing! It is my boyfriends birthday this week and I was looking for something a bit different to bake so I really want to try this. Not sure my piping will be anywhere near as good as yours though!! x

Aww fab! If you do give it a go I’d love to see pictures :-D!
This is one of my favorite copycat recipes; fun and delicious! Our kids will go gaga over this one; thanks so much for sharing!
My pleasure I’m glad you like it! It’s not only delicious but I’m sure the kids will have a ball customising it too!
Wow…that is awesome….you made your own cake. At least you got exactly what you wanted. It’s like a birthday present from you to YOU!! Hope you enjoyed it…it looks yummy!!
Haha thanks Gloria that is certainly one way of looking at it. It really was delicious and fun to make too 🙂
Happy belated birthday! This looks so good! Two of my kids have birthdays next month, I think I know what I’m baking to celebrate!
Thanks Melissa!!! I’m sure they will love it! Don’t forget to go crazy with thr sprinkles – a birthday must!
Happy belated birthday! This cookie cake sounds like the perfect option to celebrate with! Looks great
Thanks Oana 🙂
Hi dot. Sorry to hear you had some issues! Can you confirm precisely what went wrong. We’ve made it lots of times and it makes a very dense cookie cake.
Made this for hubby’s birthday yesterday and it’s amazing! And dangerously moreish!
Woohoo! Glad you liked it Sam! If you’ve got a photo I’d love to see the finished product 🙂 hope your hubby had a lovely birthday. All the best x
Is there anything I can use instead of a Vanilla Pod
Hi Jodie, any vanilla essence or vanilla extract will do just fine! If you leave it out completely it won’t be the end of the world 🙂 Enjoy!
My giant cookie is currently in the oven…….it’s not a cookie, it’s a cake!
I don’t know what went wrong as I followed the recipe. My batter didn’t look like the one in the photo on the blog, it was much wetter.
I was going to use this recipe for Father’s Day, but I’m not sure now.
Any ideas on what I have done wrong??
Oh no! Rebecca I’m really sorry to hear that! It is a “cookie cake” so the texture should be somewhere between the two. That being said it most certainly should have been more like a dough than cake batter. How wet and runny was it when it went in? It may be that it comes out more like a cake – hopefully it will still be delicious!
There was nothing doughy about it, more a Victoria Sponge mix. I’ve baked it for long as it was still slopy in the middle after 35 mins. It looks good, but not what I was looking for.
I’m gutted for you Rebecca! I can only imagine there wasn’t enough flour in the mix cake baking is such a science. If it still needs to cook in the middle I’d recommend covering it in foil to stop it browning and placing it low into the oven until cooked all the way through.
Hi there! making this now! did you use melted butter? or just room temp?
Hi Beth! Butter should be room temp 🙂 enjoy!
Nice idea but i did it exactly as the recipe and cooked it for less than the time suggested and it was like a very over done cake – all sawdusty in texture although the flavour was nice – did i do something wrong???
Hi Janey. What flour did you use? I’ve not heard anyone say it’s sawdusty before! Sorry it didn’t turn out quite like you’d hoped.
Mine turned out like a flat cake too
Hi K. Just want to be clear this is a “cookie cake” as it says in the title. It’s neither a cookie nor a cake but a hybrid of the two!
I’ve used this recipe numerous times now and it always turns out perfect and totally scrumptious!
Thanks Sam 🙂 I’m glad you’ve used the recipe so many times! I’d love to see a photo next time you do! I’m going to be making it again this weekend for a christening 😀
There’s nothing better than a giant cookie! Need to try making one for a birthday sometime! My kids would love it!
Hi Anjali thanks for stopping by! If you do get to make this do send me a pic on twitter or facebook! I’d love to see 😀
Hope you had a great day!! and how adorable does that cake look!!?? Perfect way to ring in your bday…
Thanks Swayam 😀
Giant cookies are the best!!!!
I love the extra tips! I’m not a regular baker so I forget sometimes how technical it all is 🙂
Thanks Sarah! It really is a science! Weighing the ingredients accurately is so important too. I’ve never understood why cups are so common in so many recipes! They are much more unreliable. glad you found the section useful 🙂
Yum! Cookie cakes are perfect for so many occasions. And I’m with you…bittersweet chocolate or at least semi-sweet is better than milk chocolate!
We do often chuck semi-sweet in if that’s what we’ve got to hand! A mix of both is quite nice too 🙂 glad you like the recipe Andrea!
I made the cookie cake last weekend and it was so good!
Awwwww glad you enjoyed it Jo 😀 always good to hear feedback
Hi there what chocolate drops would you recommend? Do you mean plain chocolate or dark chocolate?
TIA x
Hey there plain or dark will work just fine!
How do you make the heart shaped version? Is there a special tin I need to buy or do you bake and stick together afterwards?
Hi Laura, you can buy heart shaped tins which is the easiest method and the way I have done it in the past – http://www.amazon.co.uk/heart-shaped-cake-tin/s?ie=UTF8&page=1&rh=i%3Aaps%2Ck%3Aheart%20shaped%20cake%20tin
Though I know a friend who shaped the dough into a heart shape straight on to a baking sheet. You could use rolled up tinfoil to stop it spreading!
Hope that helps.
Hi I made this yesterday for my husband, I did exactly the same as the recipe said and I found it quite dry and crumbly. What did I do wrong, I will be trying it again sometime though.
Hi Linda. Which size eggs were you using? Make sure you have large eggs and if its a bit criumbly try adding some milk. Enjoy!
Ok thank you, I’ll have to remember that the next time. I used mixed sized eggs. The mixture seemed quite wet before cooking and it was crumbly when cooked
The texture is somewhere between an cookie and a cake. Perhaps thats why it has more of a crumb like texture?
I’d love to try this recipe but would like to know how much vanilla extract to use as don’t have vanilla pod. Also what is the icing ingredients? Many thanks Emma
Hi Emma thanks for your comment.
I’d use a tsp of extract – though it’s hard to say as different brands have different strengths!
For the icing I use the basic mix of 150g butter to 300g icing sugar. You can add a splash of milk if its too thick to pipe.
For chocolate buttercream, 75g milk chocolate, 200g butter 400g icing sugar 4 tbsp cocoa powder. Whisk together the butter, icing sugar and cocoa powder then melt the chocolate (let it cool down) and then mix into the buttercream.
Hope that helps!
Hi, how many calories would he while cake contain??
Hi Leila. I’m afraid I’m not able to calculate calorie content as it will decide on a number of different factors. The short answer is ALOT!
Making this for the fourth time now. I’ve done it for my sons birthday, my husbands and my work and now I’m making it for my parents golden wedding anniversary! The cookie is always a real winner. Thanks so much for sharing the recipe
Awww Hannah! Messages like these really make my day 😀 thank you so much. I’m pleased you love the recipe. Do you have any photos?! I’d love to pull together a gallery of readers making my recipes 🙂
Fab recipe….. my son didn’t want a cake for his birthday but loves cookies so I made this….It went down very well….
Hey I am planning to make this and wanted some help with the buttercream for decoration. Was this home made? If so could you advise?
Hi there! It certainly was homemade. The best ratio is 2:1 icing sugar to butter. So for 200g icing sugar use 100g of butter. I also add in some vanilla paste and a splash of milk until it’s a good piping consistency.
For chocolate buttercream swap out some of the icing for cocoa powder 🙂 enjoy!
Hey thanks for the help with the buttercream. Could I use a tart tin to bake this in?
I haven’t tried it myself. What kind of tart tin is it? It will probably help if it’s loose bottomed and I would try and line it with greaseproof paper if you can!
Wow just made this and it was scrummy. I used salted caramel favouring and fudge pieces as I can’t eat chocolate. Thank you for the recipe
You’ve made my day! Glad you liked it 😀
Hi, I’ve made this numerous of times and everyone loves it. I was just wondering if I put 40grams of less sugar in would it make much difference apart from being less sugary. Thanks!
Hi Sharon, I can’t say I’ve tried it with that particular ratio of sugar. It doesn’t seem like a huge reduction so it shouldn’t have that big an impact on consistency. If you do try it let me know how you get on.
All the best
Emma
Love this recipe. I’ve made it lots of times for various Birthdays. I’ve got a special multi Birthday celebration coming up so am going to try and make a Gluten free version as well as the normal recipe. Thankyou so much for sharing this recipe it definitely is amazing, even when it’s a bit drier( obviously using wrong size eggs after reading earlier comments) everyone loves it.
I’m so glad to hear that Ann. I hope it continues to be a recipe you love.
Great result, thankyou for this fab recipe, really pleased
So pleased you enjoyed it.
