Sainsbury's Café chocolate cake. It had loooads of layers. The bottom one was biscuity stuff like cheesecake base.
(for any Americans Sainsbury's is a supermarket)
Kate and I had lunch in the recently refurbished and upstairs café in the Sainsbury's near the M5 in Taunton. They've got sofas and coffee shop type drinks as well as OAP scampi & chips :D
