Chocolate Biscuit Cake for Prince William

Have you been up all night watching the wedding of Prince William and Kate?
Wasn't she a beautiful bride and he a handsome prince?
We simply can't let this day go by without posting a cake in their honor.
When I heard that he had chosen Chocolate Biscuit Cake for the groom's cake I googled it and saw that it was hardly a recipe at all.  I regularly make ganache to frost cakes and this cake is essentially broken cookies added to the melted ganache.
It's been well known that Queen Elizabeth made sure that this cake was served for tea when Prince William would come to the palace.

It's a no-bake cake with just a handful of ingredients.  You can tweak this however you like and be sure that it is nearly impossible to ruin.  I used  a combination of little bricks of dark and milk chocolate and 3/4 of a large package of Digestive biscuits.  It seems that if you open the package before you plan to make it. ..your package might not be full when you make your cake.  That happened to me so I added in some Breton Original crackers and it tastes terrific.  The cake can be made a day or two ahead, just wrap well with plastic wrap once it is firmly chilled.  Here is how I made my cake.

  • 1/2 cup unsalted butter
  • 1 cup whipping cream (33 % milk fat)
  • 1 pound chocolate. .half dark and half milk
  • 2 tbsp. cane syrup ( If not available you could use corn syrup)
  • 1 egg
  • 1 large packet  (500 gm)  or 2 7.5 ounce packages digestive biscuits. . .or 3/4 package and some Breton's.  (The exact amount is not a huge deal. . .if you want it more biscuity then add more biscuits and if you want more solid chocolate  ..add less.  Simple. If you can't find digestive biscuits where you live, just substitute any plan tea biscuit.
  1. Line a 9-inch Springform pan with parchment paper. .and then use one long strip to line the side once the pan is closed.  It will be loose in there but will quickly be pushed to the sides once you pour in your cake batter.
  2. Melt the butter over low heat, add the whipping cream and chopped chocolate and stir until melted.  If you are worried about scorching the chocolate, do it over a double boiler but do not allow the chocolate to get wet. .it will seize on you and you'll have a mess.  Alternately, heat it in the microwave and stir every minute until it is melted.
  3. Add the cane syrup and stir well.
  4. In a small bowl, beat the egg with a fork, add a small amount of melted chocolate into the egg and beat ..add a bit more chocolate to adjust the egg to heat.  Repeat this two more times so that your egg does not turn to scrambled egg.  Pour the egg and chocolate back into the chocolate and continue to stir over the heat one more minute.  The mixture should start to thicken slightly when the egg cooks.  If you are heating the chocolate in the microwave,  remove every 20 seconds and stir for an additional cooking time of 1 minute.
  5. Put the digestive biscuits in a large zip loc bad ..squeezing out the air.  Crust to almond-sized chunks.  Some pieces will turn to crumbs. .this is okay.
  6. Stir the digestive biscuits into the melted chocolate mixture.
  7. Pour into the prepared pan and chill until solid.
  8. Remove from pan and set on a cooling rack which is on a piece of waxed paper.
  9. Remove from pan, flip over to have the bottom at the top and pour ganache over, chill and serve with whipped cream.
Melted Ganache
  • 1 cup whipping cream
  • enough chocolate chips to just come to the top of the cream.
  1. Simply warm your cream until bubbles begin to form.
  2. Dump in the chocolate chips. ..just enough so you can see them poking through the cream.
  3. Stir until silky smooth.
  4. Pour over the cake and smooth over sides.  Chill.

May Prince William and his bride Kate have a long and loving relationship.
God save the Queen!


  1. I will have to try this cake,I think it would be well accepted by my family.I received my cookbook yesterday,and am looking forward to using it often.My Granddaughter was excited to see two of her favourites included,Ruhrie and Rollkuchen.

  2. :d ..I posted the same cake...ahahahahhahah... have a nice day...

  3. great picture and presentation. The recipe looks and sounds great.

  4. Sounds like a yummy cake and I love that the Queen is very much a grandmother making sure her grandson has his favorite things for tea.

  5. Way to go Lovella... you are on toop of it! I did watch the wedding with a group of friends and our daughters!

  6. Looks delicious, I made scones, and of course tea!

  7. I was curious about Prince William's grooms cake so thanks for posting a recipe! It looks delicious.

    What are digestive biscuits??? What's the closest cookie we might have in the U.S.? Possibly a butter cookie?

  8. Sorry to ask what may seem a silly question, but what are "digestive biscuits"? Do you have any idea what would be substituted for them in the U.S.?

  9. If you can't find digestives..(I saw McVities at fred meyer by the import things.. .just use a tea biscuit.

  10. So cool! I was wondering what a bisquit cake was! Thanks ladies. I am enjoying your blog!

  11. I was told graham crackers was the equivalent to digestive biscuits.

  12. It looks delicious and so easy to make. I know quite a few chocolate lovers in my family would enjoy this cake. Your photographs are beautiful!

  13. I am so happy you posted this. I wanted to make it after hearing so much about it lately.

    I live in the U.S. but I'm pretty sure the grocery store near the University sells these cookies in their British section!

  14. Thanks for showing a slice of this! For the last 2 hours I've been trying to find out what the inside of a biscuit cake looks like. I know that biscuit is cookie to us yanks so I sort of guessed at what it would look like inside. Turns out I wasn't too far off :-) This looks positively heavenly...wish I had an occasion to make it!

  15. Digestive biscuits don't really taste like graham wafers (which are definitely not British) but I'm sure graham wafers would work fine--I have seen these types of cakes made with all sorts of crackers or cookies. Digestives are sold at our local stores (I'm in Canada) so although they might not have been noticed before in yours they may be there somewhere!

  16. Such fun to make a cake in honour of Will and Kate. She was a beautiful bride.

  17. I make this as a slice, have for years!! I like to add macadamia nuts. Or you can add peppermint if you want to change the favorite. Coconut is another thing that can be added.

    My sons use to love this.

    Beautiful wedding, watched it with joy.

  18. Thanks so much for sharing! This looks like it will be fun to make with the kids.

  19. Hi:
    Just noted the recipe; but the original recipe from the chef to to Princess Diana & the boys Darren McGrady, was in the Province paper on Friday. It can also be found on Oprah's site as she had the chef on her show Friday as well. It is less in calories & uses McVities rich tea biscuits for the biscuits. There is also no whipping cream in it. I haven't tried it yet, but probably tomorrow for dessert. Anyway, I thought I'd share this with you all. Bettye

  20. This looks really good! I just noticed that there is an egg in your picture but none written in the recipe....should there be an egg in it?

  21. Annonymous. .about the egg. .good eye ..and yes I forgot to add it to my recipe. I'll go edit that now. Thanks for noticing.

  22. I've had this once and have always wondered how to make it. Thanks for sharing the recipe! Just a question - when do you add the cane syrup? I've read the recipe several times but can't seem to find it in the directions.
