Prince William's Favorite Chocolate Biscuit Cake is a delightfully-dense and rich chocolate cake made with graham cracker "biscuits" right in the batter.

This English-inspired dessert is unique in that it is rich and chocolately but also cripsy and full of crunch from the graham cracker scattered throughout.

Cooking MethodNo Bake

Cooking Vessel Size9-inch spring form pan


  • For the Cake
  • 1 pound butter
  • 2 pounds dark chocolate, chopped
  • pinch of salt
  • 1/4 cup whipping cream
  • 1/4 cup light Karo corn syrup
  • 2 tablespoons honey
  • 1 (14.4-ounce) box graham crackers
  • For the Glaze
  • 1 cup whipping cream
  • 1 tablespoon corn syrup
  • 8 ounces dark chocolate, chopped


  1. Prepare a 9-inch spring form pan by lining the bottom with parchment paper. Set aside.

  2. Place a medium saucepan with 2 inches of water over medium heat. Insert a medium size heat-proof bowl and melt the butter in it. Stir in the chocolate and salt and continue to heat until chocolate is melted, stirring until smooth. Off the heat, stir in the syrup and honey.

  3. Break the graham crackers into approximately 1-inch pieces and stir them into the chocolate mixture to coat. Spoon into the prepared spring form pan and smooth the top. Cover lightly with plastic wrap and refrigerate for 4 hours or overnight.

  4. To make the glaze, melt the chocolate in a medium size heat-proof bowl set over simmering water and stir until smooth. Add the syrup and stir to mix. Remove the sides of the cake pan and set the cake onto a serving plate. Smooth the glaze over the top of the cake using a thin icing spatula. Chill again until ready to serve.

  5. At serving time, bring cake to room temperature for 20-30 minutes. Use a sharp knife dipped into warm water and wiped on a towel to cut into thin slices.


The cake traditionally uses English golden syrup and digestif biscuits (cookies) which may be difficult to find. This version has been adjusted to use more readily available ingredients.

Maybe you could ask Prince William where he purchases his Graham Crakers and Karo Syrup as they are not available in England !

A friend of mine posted this dessert on her Instagram stories, and i was dying with jealousy at work because it was at least three hours until i get off but i knew what i was going to make this weekend. I'm looking forward to this chocolate biscuit cake, but I' ism mostly hoping the biscuit retains its crunch, and the chocolate melts in my mouth when i take a sip of tea.

Whoa, I haven't seen cake that looks like this before. I might have to request it as my birthday cake to try it out!

What a decadent looking dessert and so perfect for the chocoholic in your family. For me, it's just too much sweet on sweet going on and I'd be lucky to eat a bite without going into a sugar coma...but I really love this concept and think to lighten it up a little maybe some marshmallow fluff can be used instead of the corn syrup and honey.

This looks incredibly rich and indulgent. The graham crackers are a great crunchy addition to what is basically a really good chocolate fudge. I'd be interested in trying some Marias cookies in place of the graham crackers. The Marias are available in Krogers and almost any decently stocked Mexican grocery. One small piece would definitely fulfill my chocolate cravings.

This is like candy. Very rich! Make sure you have a drink handy. Just a small piece should satisfy any chocolate lover. The glaze is a bit much for me. I think it would be perfect served with a dollop of whipped cream instead of the glaze called for.

Crunchy chocolate = delicious. Also if I ever meet Prince William I will totally be bringing out this recipe.

I loved the crunchy cookies in the fudgy chocolate. Just a thin slice was enough to fill me. I wouldn't consider this cake, however. It's more like fudge.

This cake was a little too rich for me, but I still really enjoyed the texture that the biscuits provided. Less chocolate fudge would make this cake a bit easier to eat.

This cake is definitely more biscuit than cake, but that's not a bad thing. The cookies give it an extra crunch. It's very rich, though, so expect to only eat a little at a time.

I've never had a cake like this before. The cookies gave it a really cool texture, and the chocolate was fudgy. I loved it.

This cake had a great texture! I really enjoyed the richness of the chocolate and the crunchiness of the biscuits. This is a great treat to have with tea or coffee, but a small slice is all you need. Make sure you have some friends to share it with.

This cake was good, but it was a little rich for my taste. Next time I think I would add in some nuts and decrease the chocolate frosting. That said, it looks beautiful once it's finished!

I love digestives, but with the super thick chocolate fudge it was a bit much. And I have a huge sweet tooth, so that's saying a lot.

This was very tasty, although I would probably not define it as a cake. The fudge surrounding the cookies was incredibly rich and delicious. I'm obsessed with chocolate, and I couldn't even finish it because it was so rich!

I really like how this cake was crunchy; it was a nice change from regular chocolate cake. And yes, it definitely tasted like fudge :)

This is delicious! It's essentially a thicker fudge plus some biscuits, and the combined texture is just amazing. I definitely want to make this as a holiday dessert!

If you love cake that is more like fudge, then this is the one you should bake. It's nothing like fluffy cake, but I love the density in the chocolate. And the little crunchy biscuit bits really compliment the flavor and texture. Totally recommend this one!
