I make all my cakes in a 2lb loaf tin now - using the cake tin liners from Julian Graves.
Use a simple recipe of 2 eggs, 4oz SR flour, sugar and butter/stork plus teaspoon baking powder. All into one bowl and use electric whisk. Straight into papercase in tin and into oven at 180deg for 40-50 mins.
Add grated lemon rind and ice with lemon juice and icing sugar and hey presto, lemon drizzle.
Replace 1oz flour with cocoa - chocolate sponge - just add chocolate butter cream.
Handfuls of nuts or chocolate chips, teaspoon of vanilla, orange version of lemon cake above - possibilities are endless !!
Or, a variation of OJ's lovely Choc Orange Cake - make choc sponge as above just add rind of orange to it !
Yum tastic - no wonder me and DP have gained nearly 1/2 stone each in the 6 months we've been together. We do get thru a cake a week !!
