[Review] M&S Marks and Spencers Dark chocolate and Cherry Jaffa cakes

I was feeling peckish after dinner in TST so went to Marks and Sparks.
The Jaffa cake is basically a layer of Genoise sponge base, a layer of orange jelly coated in chocolate.
Discovered the Dark chocolate and Cherry Jaffa cakes so I had to get it because the cherry is a new invention.

The pack was a strange because it was twin packs which didn't really say on the packaging.
All of the packs on the shelf were twin packs.

Anyway, I couldn't wait to eat the Jaffa cake and it was delicious.
It tastes a bit like a black forest cake but the cherry jelly was not tart enough.

On the receipt, there is a 10% discount if you share your shopping experience at Marks and Sparks on tellmands which I did because I love shopping at Marks and Sparks but the incentive is rather useless because you have to spend $500-1000 to use that 10% discount.
