This Polish Cake is a no-cook, chocolate refrigerator cake. It's easy for children to make and is a great addition to a party table, however old you are!

The recipe was given to my mother by a Polish friend over 50 years ago, but it certainly stands the test of time. No-bake traybakes are quick and easy to make when you want a special teatime treat.
Key Ingredients in Polish Cake
Cocoa
Any sort of cocoa is good in this recipe, just make sure it isn't drinking chocolate, which contains sugar and milk powder too, and isn't chocolatey enough for this recipe.
Milk or plain chocolate to cover your fridge cake?
The original recipe used chocolate cake covering, which was very common in the seventies but has to be called something else now because it's not really chocolate.
For myself, and other adults, I use half and half milk and very dark chocolate as a coating. If I'm making a chocolate fridge cake for children I always use milk chocolate. So use what you prefer.
Ring the changes
Add a handful of sultanas or raisins when you stir in the biscuits for a fruity variation.
I also have two other versions of this no bake chocolate cake: Chocolate Tiffin and Christmas Tiffin. Both have dried fruit in and the Christmas version has it soaked in your favourite tipple.
Secrets of Success
Bash the biscuits to the right size
Bashing the biscuits is very therapeutic, but you can overdo it. You want some pieces of biscuit that are large enough to see, but some must be almost powdered so that it absorbs the syrup and butter. Look at the photos to get the idea.
The easiest way to do it is to put the biscuits in a plastic bag and hit them with a rolling pin or a meat hammer. Now that I'm more conscious of the environment, I might use a paper bag or a biodegradeable one. You could try putting the biscuits through a food processor but a) the biscuits are easily pulverised or left too big, and b) it isn't so satisfying.
What equipment do you need?
You will need a 20cm (8inch) square traybake tin or equivalent rectangular tin, probably 18cm x 22cm.
Instead of greasing the tin, I use a non-stick reusable liner. Just cut it to size and keep it in the tin. It cuts down on the washing up, as the tin is cleaner without greasing, and the cake doesn't stick. Best of all the liner goes in the dishwasher.

Alli says
I’ve grown up with this recipe. We don’t have any connections with Poland. So it’s a mystery to how we knew it. But it’s a family favourite. As kids we called it “Aunty Sue Mud Cake”. It’s a must-have for any of our family get togethers. The only extra ingredient we have is a big handful of sultanas.

Hi Alli, Sultanas sounds like a great idea. I might pinch that one. Thanks 🙂
