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.

Chocolate biscuit birthday cake aka tiffin.

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.

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.

  1. 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

  2. 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

  3. 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

    1. 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.

  4. 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

    1. 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/

  5. 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…

  6. Wow Choclette this looks awesome! So decadent and so much chocolate mmmm! Thanks for linkin my bars 🙂

  7. 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

    1. 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 😀
