The inspiration for this chocolate biscuit cake came when I went for a stroll downtown with the kids a couple of days ago. We came up with the idea to make Prince William’s groom’s cake which he has requested be served at the wedding reception. 

Apparently, this easy no-bake refrigerator cake is a childhood indulgence of his and a particular favourite of the entire royal family. With this idea in mind, we dropped into Fat Nanny’s grocery store on Duckworth Street.

There, I procured the necessary Lyle’s golden syrup and a large sleeve of McVities original digestive biscuits. Both Lyle’s and McVities are venerable brands in the UK, which adds a little extra authenticity to the recipe on this occasion.

Dark Chocolate Chips, to melt and dip the biscotti

I use good quality dark chocolate chips at about 50% cocoa in this recipe but semisweet chips can also be used.

Golden syrup is a little difficult to come by in these parts, so I would use dark corn syrup as a substitute. Any brand of digestive biscuits will do.

Dark chocolate is the way to go with this recipe but you can mix semisweet and dark chocolate if you like the chocolate flavour to be a little lighter.

I’ve also read numerous versions of this recipe online that include such ingredients as dried cherries, and roasted nuts. I even saw one ingredient I might just try the next time I make this; broken Crunchie bars!

There’s lots of room for experimentation with this recipe, so go discover your own favourite version.

Are you sure a pound of butter?

Will you clarify the amount of butter, please. The cake calls for 1 pound (which is 2 cups), and the recipe for the squares reduces the ingredients by half. Except for the butter, which is quartered, to 1/2 cup. Which I amount of butter is correct? (I assume the lesser amount.)

I use Malte Milk Biscuits & Milk Chocolate which has always proved to be a winning combination

You way overcomplicated this. It's refrigerator cake, and it requires two ingredients only: milk chocolate, and digestive biscuits. Bash the digestive biscuits into small pieces, melt the chocolate in a double boiler (or Pyrex bowl over a saucepan), stir the biscuit pieces into the chocolate, pour the mixture into a cake tin, smooth the top, pop it in the fridge or freezer overnight. In the morning, carefully cut into small rectangles with a sharp knife. That's how it's traditionally done in England.

In Australia we can buy a digestive biscuit called chocolate wheaten but it is topped with chocolate (the more the merrier)I’m going to use this as my rocky road base recipe. Thanks so much. Kerry 😀
