Chocolate Biscuit Cake: A Bounty Full Birthday
A rich and indulgent chocolate tiffin, also known as biscuit cake or fridge cake. Studded with coconut and flavoured with coconut liqueur, this chocolate biscuit cake is a not overly sweet adult version of a children’s classic.
Last year I asked CT what he would like for his birthday. A trifle was his response. OK. I duly made a trifle and very nice it was too, but this year I didn’t ask. I know he’s very fond of tiffin, otherwise known as biscuit cake or refrigerator cake. If Prince William can have one for his wedding, I couldn’t see any reason why CT shouldn’t have one for his birthday.
Chocolate Biscuit Birthday Cake
But it was a birthday cake, so it couldn’t be just any old biscuit cake. It had to be a full on tiffin with plenty of chocolate and one that we could easily slice.
I remembered seeing a potentially suitable recipe in Kate Doran’s excellent book, Homemade Memories, which I reviewed a while back. Well, it was suitable and I duly went about adapting it and adding a rich chocolate glaze to the top, just in case there was any danger of chocolate stinginess. In the end, the cake used a whopping half a kilogram of chocolate!
Kate’s recipe included honeycomb, but I omitted that and used toasted coconut flakes instead. CT has a rather unhealthy attraction to Bounty bars, so I thought I’d go several better than that. Not only did I use coconut flakes, but I also added some Latvian chocolate coconut vodka that I won from Dashing Dom over at Belleau Kitchen last year with this pomegranate choctail.

CT was duly impressed and vowed to give up Mars confectionery – if I made this every week. It had a good coconut flavour, sliced well and was richly decadent. This is not a cake to be eaten on the go as it needs to be savoured with a nice cup of tea. Heaven.

Much as I was tempted to enter my Black Forest Gateau into We Should Cocoa, it was this tiffin I had in mind for it.

Gosh, this looks,absolutely delicious, what a lucky thing to have this for a birthday cake. My family would adore this too.
That’s what I thought too Lucy. I would love someone to make me this for my birthday – tiffin is a major weakness of mine.
That looks wonderful and I bet tastes amazing. I would never have thought of adding the booze to a tiffin cake but it’s a great idea. Now can you make it daily?! GG
I regularly add amaretto GG, it goes brilliantly well. This one was a little more refined 😉
What a fab adaptation on tiffin & birthday cake. This looks absolutely gorgeous & adding coconut just sends it over the top. I know a couple of people who would love me to make this for their birthdays. Sammie
If you can’t have an over the top cake on your birthday, there’s not much point having a birthday I reckon 😉
CT is one very lucky man – this cake looks fab! Can you make me a birthday cake?
Haha Sarah, I seem to have created a job for myself 🙂
Oh Choclette this looks amazing. I love coconut with chocolate so this is definitely going on my to make list.
It’s really quite addictive George and should come with some sort of warning 😉
Your bounty bar look incredible! I would love this for my birthday too.
Thanks Angie, I would love one for my birthday too 😉
OMG! How decadent is that! Looks like the perfect birthday treat 🙂

PS Happy birthday Mr T&T
Thanks Janie, it was already a few weeks ago now – how time flies.
great birthday cake – just wanted to check I could comment – after having problems both commenting and linking up to WSC I found that when I started to navigate around the site I could finally comment and then when I came back here I could comment here too – fingers crossed the problem is fixed
Thanks for your persistence Johanna. How very strange, but like you I’m crossing fingers. I always enjoy your comments and have missed them.
I’ve not made a refrigerator cake in years! This looks fab….. Perfectly crunchy-coconutty-chocolatey heaven…. Happy birthday to CT! I hope he gets to enjoy many more such masterpieces.
From time to time I have to indulge in a bit of tiffin and the beauty of making your own is that it doesn’t have to be sickly sweet and full of margarine. It would be so easy to make it GF too.
My God! How great thou art! That’s tremendously beautiful and I need it in my belly right now. Hahaha. Wow.
Haha, thanks Byron. Would a virtual slice be any good to you?
refrigerator style cakes have always been a favourite of mine – I remember a relative used to make one with cut prunes in it too and it had a lovely chewiness to it when served cold from the fridge
Ooh I like the sound of including prunes CC – you are such a great source of inspiration 😀
This looks AMAZING! I’ve been craving something like that for a while now so I will be making this cake sometime this week!! xx
Thanks Diana. It really is delicious, but not something to make very often – it is far too tempting. Looking forward to seeing your version.
Oh please can I come visit you on my birthday and get a slice of this?
If you fancy dropping by Bintu, I’d be delighted to make you one 🙂
Bars looks yummy
Thank you. It’s dead easy to make, so do give it a go.
This looks so delish.
Thank you, it really was most delicious 🙂
These look so yumm.. Is there a way to make it eggless?
I don’t normally make Tiffin with eggs, Abhilasha, but it does make it additionally rich. This one for example has no eggs – /2013/11/chocolate-amaretto-biscuit-cake/
This sounds amazing and oh so tempting since i’m on a diet!
Ah yes Michelle, possibly not what you should be eating on a diet 🙁
‘Biscuit Cake’ are my weakness and with Chocolate Coconut Vodka, this sounds even more yum.
Biscuit cakes are a universal favourite I reckon Molly but it’s nice to have an adult only version sometimes.
That looks and sounds spectacular. I wish someone would make me something like that for my birthday.
Haha, me too Tracy. It seems the fate of food bloggers is to have to make their own birthday cakes 😉
That is some serious foodporn there..the instructions are so detailed and the cake looks delicious.
thanks for the recipe. 🙂
Thank you, I like to think I can manage a bit of food porn from time to time 😉
Well I’m glad to be of service. It looks like a stunning cake and CT is one lucky chap! I actually need a slice right now, if that’s ok? Please…
Sadly, that one’s long gone Dom. I could do with a slice of it myself 😉
Looks fabulous! That Stoli looks really interesting too – never seen that flavour before.
Thanks Helen. The Stoli is really interesting. I’m not much of a drinker, but I do like it in baking, oh and maybe the odd cocktails 🙂
Ahhh fridge cakes are one of my faves! Not had one in years though 😛 Need to make one soon! Looks so good Choclette 🙂
Thank you Nadia. I think fridge cake is one of those universal favourites which we all remember so well from childhood.
Wow Choclette this looks awesome! So decadent and so much chocolate mmmm! Thanks for linkin my bars 🙂
Your bars look great Sus and so much healthier too 🙂
Good Morning to you, I agree with CT, Bounty bars are fabulous…. yes I have that same unhealthy attraction to these gorgeous little bars…. a mix of chocolate and coconut is perfection. I have made Refrigerator Cake before, but I have never added vodka….. a nice little addition. Guess what….. I will be using your recipe….. and guess what else…. I know I am going to love it as much as CT did.
Best Wishes
Daphne
Hello Daphne, lovely to hear from you. I like the combination of chocolate and coconut too, but I find the bounty filling far too sweet. I hope you make it and hope you like it as much as CT did 😀
