  • 200g caster sugar

  • 200g milk chocolate

  • 200g butter, softened

  • 4 eggs

  • 200g plain chocolate

  • 1 packet of orange jelly

  • 200g self raising flour


For the sponge

  1. Preheat the oven to 180C/350F/Gas 4.
  2. Cream the butter and the sugar together
  3. Beat in the eggs.
  4. Sift over the flour and fold in using a large spoon
  5. Transfer to a large sandwich tin
  6. Bake for 30 minutes or until you think it's done.

For the jaffa/jelly

  1. Make up a standard packet of orange jelly but with half of the required water so the jelly is thicker. Let the jelly set on a dinner plate covered in cling film so you can easily lift the jelly later on.

For the chocolate covering

  1. Once the jelly is set (good to leave it overnight), tip the plate onto the sponge base and trim to the desired shape.

  2. Melt the chocolate in a bain-marie or microwave, I used a mix of plain and milk chocolate but you can change this to taste. I layered the chocolate on with a pastry brush initially just to make sure the jelly didn't melt. Once you do the first layers you can then build it up to whatever thickness you like.

Handy Hint

Use cling film on a dinner plate in order to get a good depth of jelly, the cling film ensures you'll be able to lift the jelly off cleanly!

    Am currently in the 'covering with chocolate' part, I've been returning it to the fridge between layers of choc to let the jelly re-set. The very warm evening is not helping!
