I’m currently in love with this no bake chocolate fridge cake. Supremely chocolatey and easy, what’s not to love?!! Chocolate, cookies and Maltesers all mixed up and set so that you can slice it like a cake

  • Super delicious
  • 8 ingredients
  • 15 minutes to make
  • No oven required
  • Great for kids to make but grown ups love it too
  • Make ahead

No bake desserts are always winners in my book and this chocolate biscuit cake is no exception. It’s a great dessert to get the kiddies involved in since the only real cooking is melting the chocolate mix together in the microwave and heating the cream for the ganache.

This Caramel Malteser Slice is another great no bake recipe using Maltesers too and this Chocolate Hedgehog Slice is a very similar Aussie classic treat.

This no bake cake was just what I had been searching for. It was lovely and moist too.

What is no bake chocolate biscuit cake?

You might also know this as a chocolate biscuit cake, a favourite of the royal family, and one that Prince William had as his grooms cake.

It’s also very similar to what we know in Australia as a hedgehog slice and consists of broken up biscuits (cookies) mixed into a chocolate mixture that sets to an almost fudge-like texture. This Malteser traybake is actually a no bake bar that’s a combination between hedgehog slice and this fridge cake.

The biscuits soften a little, so I added Maltesers to add a few little crunchy bursts and I top mine with a very simple chocolate ganache. I know you’re going to love this one.

How to store fridge cake

Chocolate fridge cake needs to be kept cool at all times as it will begin to soften and if left in hot weather may start to melt and be gooey. Keep it in the fridge until 30 minutes before you want to serve.

It will last well in the fridge for 4-5 days in an airtight container or tightly wrapped in plastic wrap. You can freeze it too, also wrapped in plastic wrap and / or inside an airtight container for 1-2 months.

Oh yeah, did I mention this can be made ahead too? Well it can. Since it’s a cake that sets in the fridge you can make it a couple of days in advance. Make sure to store it in an airtight container.

Cooks tips

  • Biscuits: Milk Arrowroot or Milk Coffee biscuits work perfectly but you can also use digestive biscuits like McVites or Graham Crackers.
  • Golden Syrup is important in this recipe – it gives it sweetness and adds to the rich flavour. I most often use CSR brand but Lyle’s golden syrup is also wonderful.
  • Cocoa: I like to use Dutched Process Cocoa for it’s dark colour but any cocoa will work.
  • Just melt the chocolate mixture, making sure not to overheat. This should take no longer than 2 minutes in the microwave but make sure to do it in 30 second bursts and stir well between each one.
  • No need to wait for the cake to set before making the ganache, you can add this straight away.


There are so many ways to customise this cake. Here are just a few ideas

  • Biscuits: As noted above, you can use anything from regular tea time biscuits to Graham crackers and everything in between. Just go for something crunchy. I imagine Biscoff cookies would be amazing, and so would Oreos.
  • Chocolate: Use milk chocolate in the ganache instead of dark.
  • Maltesers: You could leave them out or add more. For that matter swap them for broken up Kit Kat or honeycomb.
  • Add ins: Try nuts, coconut or marshmallows – or add them all to get a rocky road cake. Or how about some dried fruit or sprinkles.
  • Decorating: I used Maltesers to decorate this one really simply but you could make extra ganache and pipe it on, use sprinkles or chocolate curls or even crumble up loads of Maltesers and pile them up in the middle.

  1. Biscuits: Milk Coffee or Milk Arrowroot work perfectly, but you could also use graham crackers or digestive biscuits (like mcvites). You just need a crunchy cookie.
