Orange Cupcakes with Orange Blossom Buttercream Frosting

These are from the Primrose Bakery book. The cakes were nice, with only a subtle hint of orange. The frosting was nice too but waaaaayy too sweet! The recipe uses 115g of butter and FIVE HUNDRED grams of icing sugar. And no, I did not follow the recipe. I only used 230g of icing sugar and you can tell because the frosting was so so soft and 'runny'. But even then, it was so SO sweet. I really can't imagine how it would taste like if I had followed the recipe!
