A couple weeks ago I showcased a recipe for traditional English fruit cake, the sort of thing that Prince William and Princess Catherine sliced at their wedding reception on April 29. 

Well today I’ll post the recipe for their other cake: the groom’s cake. The recipe is courtesy of royal chef Darren McGrady (, who was Princess Diana’s personal chef. This is a treat that’s been in the royal family for years, and was a teatime standard at Buckingham Palace (beloved by HRH). It was a childhood favorite of William’s, so when it came time to choose his groom cake he went with this memorable delicacy. 

This no-bake concoction of decadence is basically chocolate, butter, sugar, and biscuits and looks absolutely divine.

Servings: Makes one 6-inch round cake (8 portions)

  • 1/2 tsp. butter , for greasing
  • 8 ounces Rich tea biscuits
  • 4 ounces unsalted butter , softened
  • 4 ounces granulated sugar
  • 4 ounces dark chocolate , for the cake
  • 1 egg
  • 8 ounces dark chocolate , for coating
  • 1 ounce chocolate , for decorating
To make cake: Lightly grease a 6″ x 2 1/2″ cake ring and place on a tray on a sheet of parchment paper.

Break each of the biscuits into almond-size pieces by hand and set aside.

Cream the butter and sugar in a bowl until the mixture starts to lighten.

Melt the 4 ounces of dark chocolate and add to the butter mixture while constantly stirring.

Beat the egg into the mixture.

Fold in the biscuit pieces until they are all coated with the chocolate mixture.

Spoon the mixture into the prepared cake ring. Try to fill all of the gaps on the bottom of the ring because this will be the top when it is unmolded.

Chill the cake in the refrigerator for at least 3 hours.

To coat and decorate: Remove the cake from the refrigerator and let it stand while you melt the 8 ounces of dark chocolate.

Slide the ring off the cake and turn it upside down onto a cake wire.

Pour the melted chocolate over the cake and smooth the top and sides using a palette knife.

Allow the chocolate to set at room temperature.

Carefully run a knife around the bottom of the cake where the chocolate has stuck to the cake wire and lift it onto a tea plate.

Melt the remaining 1 ounce of chocolate and use to decorate the top of the cake.

I've had a passion for everything British my entire life, despite being raised as a small-town girl in the American Midwest, After years of dreaming, I got the chance to live and work in England for an entire year. Now I write about my favorite country, and hopefully inspire my fellow Britophiles to get over there and experience it for themselves.

    She’s not Princess Catherine, she’s Catherine, Duchess of Cambridge. If William hadn’t been created DoC, she’d be Princess William of Wales. One is only “Princess Your Own Name” by birth (or by gift of the title by the Sovereign), not by marriage to a Prince.

    And before anyone mentions Princess Diana, that was not her correct title which was Diana, Princess of Wales.

    @ Neil and Carol – You are certainly right! Once more, an example of how American tabloids have ruined proper British forms of address!
