I found these Christmas cupcakes at Michel's Patisserie at Indooroopilly Shoppingtown but would guess that they are available at other Michel Patisserie outlets across town.
They are a basic sponge cake with a soft white icing and hard sugar decoration. The cake is fairly tasty for the price of $2.50. I wouldn't call them gourmet but I was pleasantly surprised.
Bottom line: value for the price.
