This was a delicious cake and very popular with my guests. I found the mixture to be a little too much for my cheesecake tin, but I increased the mixture by a half and divided it between two 8 cm sponge cake tins. This made two wonderful cakes. Put first tin on trivit. Place upturned empty tin without base on top to separate and place second cake carefully on that. Bring to pressure and cook in usual way. Remember to adjust ingredients carefully. 300g of chocolate, 3 eggs, 3 tubs of cheese, 8oz sugar etc. A 300ml carton of double cream will suffice. You will have 2 delicious cakes for the cost of cooking 1.
