Chocolate Biscuit Cake

Chocolate Biscuit Cake (also known as refrigerator cake) has long been a favorite of children in the United Kingdom. It's place in society was sealed when Prince William requested one as his "groom's cake" at his wedding to Kate Middleton. Simple and super fun to make, with no baking required; even the youngest kids can get involved in helping to create these. And everyone in the family will enjoy helping to eat them!

  • 150g milk chocolate (cadburys dairy milk works well!)

  • Step 5

  1. Place approximately 4-5 biscuits into the freezer bag and crush until they are broken down into small crumbs. You can speed up this process by using a rolling pin to roll over the biscuits and to smash them. Add to a large mixing bowl
  2. Repeat until all the biscuits are reduced to crumbs
  3. Break up the chocolate and melt. This can either be done by placing the chocolate into a small bowl placed over a pan of simmering water and stirring - or by heating in 10s increments in the microwave, stirring at the end of each 10s.
  4. Pour the melted chocolate into the bowl with the biscuit crumbs. Stir until all the crumbs are coated in chocolate.
  5. Take a small non stick baking tin e.g. a loaf tin, and transfer the crumb mix into the tin. Using the back of a spoon or better still your fingers (!), push down on the mixture until you have a layer of compressed crumbs across the bottom of the tin.
  6. Using the back of a knife, score lines across the surface of the mix to create squares about 2"x2".
  7. Place a smartie (or other candy piece) in the center of the square
  8. Place in the refrigerator for about an hour to set, and then remove and cut into squares.
  9. Enjoy


  1. Be careful when crushing the biscuits so as not to make a hole in the plastic bag - otherwise the crumbs will make a big mess
  2. SAFETY: Adult supervision is required to melt the chocolate.
  3. SAFETY: Ensure that the mix has cooled before using your hands to press the mix into the tin.
  4. When you first mix the chocolate and biscuit crumbs, it will look as if there is not enough chocolate to coat the biscuit. Do not fear, as you continue to stir the chocolate will quickly being to coat the crumbs
  5. You can also add nuts and dried fruit to the mix before adding to the tin. And if you wish for a very indulgent version, you can add melted chocolate to the top.
  6. Did you know that Prince William requested that a chocolate biscuit cake be served at his wedding as his groom's cake. Apparently chocolate biscuit cake was one of his childhood favorites. The grooms cake was made using a special private recipe from Buckingham Palace and was made by McVities in collaboration with British chocolatier Barry Colenso:

These were fun and easy to make, the hardest part was stopping my little one eating the ingredients before we had made the cake!
