Mum made two different chocolate chip treats when we were kids. My brother and I both loved the chocolate chip cookies but he was not a fan of the chocolate chip muffins, which was great for me. From memory I think it was because of the orange flavour which is kind of funny now as he loves orange chocolate, so much so that the hubby and I gave him about five kilograms of Jaffas for Christmas a few years ago. Needless to say, he went off orange chocolate for a while again.
For the final tier for my High Tea, I needed something small so I decided to make Mini Orange Chocolate Chip Muffins which would fit quite nicely.
I am quite addicted to piping a rose pattern having honed my skills on a 
Mars Bar Slice is probably not something that you usually see on a high tea menu, but when I recently purchased a new three tiered server I was in an extreme chocolate mood and given had a few Mars Bars on hand, I thought it was a good enough reason to make a childhood favourite.
