Chiffon cake for birthdays

Somewhere along the track in our family, we changed from the fun novelty cake for our birthdays to a chocolate chip chiffon cake, which is sort of like a huge sponge cake only better.  Mum would make some sort of boiled frosting for the cake (and now my sister does).  It is delicious, especially with icecream and /or cream.  I am on a diet at present, but will have a treat when my birthday comes along in September.
