I first wrote about chocolate biscuit cake around the time of the Royal wedding of Prince William and Kate Middleton. That was way back in April of 2011. It was chosen by the prince as the groom’s cake at the wedding reception. Read that post here.

The full recipe makes quite a large “cake”, which in reality is more akin to a giant sliceable chocolate bar. It is great to have around at the holidays to be enjoyed in small slivers, like fruitcake.

Prince William's Chocolate Biscuit Cake

The full chocolate biscuit cake is perfect for dessert for a large group or to be enjoyed over the course of a week. This favourite of the entire royal family is rumoured to be required to return to the dinner table every day until finished.

Most dessert leftovers, apparently go to the palace staff but not this one. I can definitely see why. With all that creamy smooth chocolate interspersed with crunchy cookie chunks, it is pretty irresistible.

Dark Chocolate Chips, to melt and dip the biscotti

Dark Chocolate Chips at 50% cocoa, is my preference, but you can use whatever chocolate you like best.

Prince William Squares are a new holiday favourite.

This year during the holidays, I again wanted to serve this delicious, super easy, no bake treat on Christmas day. With my Pecan Pie already on the dessert menu as well as my simplified Christmas Pudding, a full cake would just be overkill.

In order to downsize the recipe, I decided to do what I had thought about for a while. Make the recipe as no bake cookie bars! I figured making them at half the height of the cake would be ideal for more bite sized treats.

With a little applied geometry was required to adjust from a round 9 inch springform. I figured making a half batch in a 9×9 square pan would work well. It worked out beautifully.

The original cake recipe calls for a covering of ganache over the whole cake. That layer is really nice for presentations sake. I did not feel it was necessary in this case so I omitted that step in the recipe.

The cookies/biscuits in this recipe.

McVities Digestive Biscuits.

McVities Digestive Biscuits. This recipe uses about half a 400 g package.

The digestive biscuits (cookies) in this recipe could be substitutes for any crisp cookie you like if they are not available in your area. McVities Digestive biscuits are what I used and they are readily available across Canada.

My Christmas guests loved these little squares, particularly my daughter Olivia, who may have eaten half the batch over a few days!

I make a similar recipe that my Aunt gave me 40 years ago topped with coffee buttercream. One of my favorites.

I'm wanting to make this for Christmas but I notice some big differences between this and the version posted by The Royal Chef. Yours doesn't use an egg and doesn't include creaming butter and sugar together at the start. Can you advise why the differences so I can decide which direction would be best for me?
