Many secrets surrounded the Royal Wedding of Prince William to Kate Middleton, but the groom's cake is no longer 'under wraps.' Former Royal Chef Darren McGrady has agreed to share the recipe with us! This chocolate biscuit cake is a tea-time favorite of the Queen, and was requested specifically by Prince William for the wedding.
Lightly grease a 6 inch by 2 ½ inch 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 chocolate (in a double boiler if you have one). Off heat, add the butter mixture whilst constantly stirring.
Beat in the egg to 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 un-molded.
Chill the cake in the refrigerator for at least three hours. Remove the cake from the refrigerator and let it stand while you melt the 8 ounces of 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 it 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.
