Ingredients for 5 portions:
- Tesco values sponge mix
- 100g dark chocolate tablet
- 20ml vegetable oil (or hazelnut oil)
- 1 orange
- 150g marmalade
- 1 egg
- Butter for greasing
Carefully follow the instructions on the sponge mix package to prepare the two halves of the sandwich. Before pouring the mix to bake, grate and mix in the zest of 1 orange.
Once the haves are baked, leave to cool for few minutes and turn both of them upside down.
Score the base of both cakes and evenly spread the jam on them making sure that it is well absorbed. Now put both cakes on top of each other on the jammed side. Set aside.
Preparing the chocolate covering. Break the tablet of chocolate in small pieces and place them in a heat-proof bowl. Add the 20ml of oil. Now, in a small sauce pan, boil 300ml of water and place the bowl containing the chocolate pieces in it while it is still simmering.
Gently stir the contents of the bowl until all the pieces of chocolate are melted and all what is left is a very smooth, rich and glossy chocolate sauce.
Now place the sponge sandwich on a rack or a plate, then pour the chocolate sauce on it making sure to cover all the top and the sides of the cake too. One single layer of the sauce is just enough to keep it light. Decorate the cake before placing it in the fridge to allow the chocolate to harden. 30 minutes to 1 hours should be enough depending on the thickness of the chocolate covering.
The cake above was decorated with heart shapes filled with white chocolate shavings on the outer and poppy seeds in the inner heart. The fresh orange piece were lightly dipped in caramel before being placed on the edges of the cake. Make sure to decorate your cake before placing it the fridge to harden.
This would be a great birthday cake or one to offer to friends.
