The Best 15 Minute Chocolate Biscuit Cake recipe -I’ve tried hundreds!

last slice standing

The birthday cake is often a bit of a last minute panic in our house because I’m not a perfectionist when it comes to baking. And when there’s a party, there’s always a lot to organise so an easy to make home made cake is an ultimate winner in my opinion.

Chocolate Biscuit Cake is one of my (many) weaknesses- I hope heaven is filled with chocolate biscuit cake because then I’d eat it non-stop and never worry about my shape. I craved it just after I had my first baby and I wouldn’t be surprised if my milk was chocolate flavoured. I stopped when my baby got spots and the midwife said, “Have you been eating chocolate?” (Oh the misery!)

This recipe really did only take me 15 minutes to make. It needs four hours afterwards to set though.

You could make this with dark chocolate but leave out the cocoa for an extremely rich cake. Adding walnuts makes it kind of a posh alternative option for adults. Adding raisins makes it sort of healthy. 🙂

So this is what you need:

  • A 20cm cake tin
  • 200gm good milk chocolate
  • 125gm butter
  • 75gm golden syrup
  • 2 tablespoons cocoa
  • 1 egg
  • 50gm digestive biscuits
  • 100gm ‘Rich Tea’ or ‘Marie’ biscuits
  • 50gm roughly chopped walnuts (optional)
  • 50gm raisins (also optional)
  • ANOTHER 200gm milk or dark chocolate for the topping.

And this is how you do it:

  1. Set a double boiler on the stove (quicker to heat if you boil a kettle first and use the water).
  2. Add chocolate broken into blocks.
  3. Next throw in the butter, syrup and cocoa.
  4. Grease and line the tin with baking paper while you wait for the chocolate to melt
  5. Stir the pot a few times.
  6. Bash biscuits roughly in a bowl (I use a pestle and a bowl larger than my mortar)
  7. Stir the pot a bit more.
  8. Add walnuts and raisins to bashed biscuits.
  9. Once the chocolate mix is smooth, break the raw egg into the hot mixture and stir gently to pasteurize the egg.
  10. Pour melted chocolate mix over biscuit mix, stir all together and pour into the loaf tin.
  11. Seriously, leave it in the fridge to set for at least four hours.
  12. Melt the other 200gm chocolate and pour over the top, allow to set and decorate if you like.

To serve, turn it out of the tin and slice. Leave a few pieces for your guests.
