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.
