Cupcakes, you can wake up Sophie in the middle of the night for them. Or she will wake you up 5 'o clock in the morning, ready to make some. She must have found the hearts and flowers I found on sale the previous day.
Annabel Langbein, the writer of my favourite cookbooks, has a simple but delicious recipe, no mixer required (link). The frosting in the recipe looks divine, but some crushed raspberries for colour and icing sugar will give you a perfect thin layer of icing, just enough to glue the decorations in place. (How high do you want your sugar high to be?)
