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 it’s not unheard of for me to end up with a cake that looks more pan than cake. Chocolate Biscuit Cake is my kids’ favourite, and mine too, so I’m always more than happy to make it for their birthday parties.
When there’s a party, there’s always a million other thing to organise and think about, so a quick and easy to make home made cake is an ultimate winner in my opinion. (It’s also apparently the Queen of England’s favourite cake so good enough for royalty).
“Woah, that cake was pretty awesome” actual words from 13 yr old son
This recipe really only takes me 15 minutes to make, it needs four hours afterwards to set though.
Adding walnuts makes it kind of a posh alternative option for adults (and royalty). Adding raisins makes it even feel healthy.
So this is what you need:
- A round 20 cm cake tin, greased and line the base with grease-proof paper
- 400 gm rich tea biscuits
- 200 gm digestive biscuits or finger biscuits
- 250 gm butter
- 1/2 cup of sugar
- 8 tablespoons cocoa
- 4 eggs
- 6 teaspoons vanilla essence
- 50gm roughly chopped walnuts (optional)
- 50gm raisins (also optional)
- 200gm milk or dark chocolate for the topping.
And this is how you do it:
- Put the butter, sugar and cocoa into a saucepan and melt slowly over a low heat, stir intermittently and don’t allow to boil.
- Bash biscuits roughly in a bowl, largest chunks should be no bigger than a euro or pound coin (I use a pestle and a large bowl).
- Add optional walnuts and raisins to broken biscuits.
- Remove melted chocolate mix from the heat and allow to cool for a few minutes.
- Whisk eggs and vanilla with a fork in a separate bowl.
- Pour raw egg into the hot mixture and stir or wisk briskly to pasteurize the egg.
- Pour melted chocolate mix over biscuit mix, stir all together and press into the cake tin.
- Leave it in the fridge to set for at least four hours.
- Melt the 200 gm chocolate and pour over the top, allow to set and decorate if you like.
For decoration we have pressed ‘jazzles’, white chocolate buttons or Smarties into the melted chocolate topping while it is still runny so that they set into the top. We have also glued (with melted chocolate) Kit Kat, Jive or Twix bars around the sides to create walls.
To serve, turn it out of the tin and slice. (Leave some pieces for your guests 😀 ).
