There is a rule, in my house anyway, that on Australia Day you must eat a lamington. I did kind of break that rule this year, although we did eat Pavlova instead, but I think I more than made up for it by making a whole bunch of them a couple of days later.
A friend of mine from Mexico Victoria was staying with us at the time, and they do things a little differently down there by filling their lamingtons with jam so I made half of the batch the traditional way with just the plain cake dipped in chocolate and covered with coconut, and the remainder filled with jam and covered in coconut. I did run out of coconut so the remainder of the jam lamingtons were covered with coloured sprinkles, hence Sprinkletons were born.
