Chocolate Biscuit Cake Recipe

This is the recipe for a chocolate biscuit cake I made for Ruairí’s 6th birthday. He’s not a huge lover of cream and sponge type cakes so I wanted something he’d love. This was a winner not only with him but the whole family. As you can see it I decorated it for him with some of his favourite Lego, Star Wars. This was all the decoration he needed.


This is a recipe that doesn’t have exact amounts so you may need to play around with it and it’s ingredients are local to me so you may want to substitute what you have and what is available, it is a recipe that lends very well to tweaking.

Chocolate Biscuit Cake

Ingredients :-

  • 4 Large bars of cadbury chocolate (any milk chocolate should do though)
  • Butter
  • 1 Pack of chocolate digestive ( I used dark chocolate ones just for added flavour)
  • 1 Pack of ordinary digestives
  • 1 Large re-sealable bag of malteasers
  • 4 Crunchie bars
  • 2 Kinder Buoenos
  • 1 Can of condensed milk
  • Maple syrup

Method :-

Line an 8inch tin with cling film.

  • Melt the chocolate in the microwave with a good chunk of butter. It melts really quickly so keep an eye on it and stop and stir it.
  • I poured a small amount of the chocolate into my tin and let it set in the fridge. This gave me the chocolate top to the cake.
  • In a large freezer bag crush the biscuits, malteasers, crucnhies and buoenos.
  • Add the tin of condensed milk to the chocolate and butter.
  • Combine the wet and dry ingredients and add a large dollop of maple syrup.
  • When all the biscuits are coated add to the baking tin and allow to set in the fridge.


I don’t normally have a recipe that is so lacking in actual quantities. I am a baker at heart, I like quantities and methods and I don’t do so well with dollops and chunks but what I will say about this recipe is that it works.  It was a really tasty cake and everyone loved it. It might also look like it’s not so covered in chocolate and that’s ok too, it’s supposed to look like that.

Do take it out of the fridge a good hour before you want to serve it.

    This sounds so yummy, Now I just have to google about half of the ingredients to see what they are so I know what to ‘sub’ for them. Thanks for sharing.

      Yes do it’s very much a cake made from chocolate and bars available here in Ireland but I’m also pretty sure you will find substitutes.

    Looks yummy but I have no idea what most of the ingredients are! 🙂 What a wonderful birthday he had even though he was still dealing with spots.

  4. It looks yummy but from the sounds of the ingredients I don’t know if I could make it….I’ll google like Marsha and see what I come up with. As long as he liked it that’s all that counts.
