Recipe for Prince William's Chocolate Biscuit Cake


1/2 teaspoon of soft butter (first amount)
8 ounces or 227 grams of McVities rich tea biscuits.
4 ounces of butter, softened (second amount)
1 egg
4 ounces of good quality chocolate, dark (first amount)
1/2 cup of sugar
8 ounces of good quality chocolate, dark (second amount)
1 ounce white chocolate


You will need a springform pan. Line the bottom of the springform pan with parchment paper, waxed paper or silicon paper. Butter the sides, using the first amount of butter.

Chop up the McVities rich tea biscuits so they form small pieces approximately the size of a nut.

In a separate bowl, cream together the sugar and the second amount of butter.

Using a double boiler or your microwave, melt the first amount of dark chocolate. Pour this melted chocolate into the butter mixture and stir. Beat the egg well and add the beaten egg to the creamed mixture. Mix again.

Add the chopped up biscuits and mix well. Be sure that all of the biscuits are thoroughly covered with the chocolate mixture.

Pour this mixture into your lined pan. Press it down well. Remember that the ingredients at the bottom of the pan will form the top of the cake when it is removed.

Place your chocolate biscuit cake in the refrigerator and chill for about three hours. You want to leave it there long enough to set.

When ready, remove your cake from the fridge and let it sit at room temperature while you melt the second amount of dark chocolate. Also melt the white chocolate, but in a separate bowl or container.

Turn the springform pan upside down over a serving plate and unmould the cake.

Drizzle the melted dark chocolate over the top and sides of the cake, forming an icing.

Lastly, drizzle the white chocolate over top of the dark. The two chocolate will tend to run together and that is fine.

Now Prince William's Chocolate Biscuit cake is ready to serve. Your guests will eat like royalty.
