The first two ideas are something you can do yourself. I imagined the Owl cupcakes from a Back-to-school party. It is so easy to do that you can ask your kids to help you. I got that idea from Real Simple. On chocolate icing, you use 2 Oreo halves (cream-side up) and 2 Junior Mints to make the eyes. Add a Runts banana for the beak.
Jewellery making parties are popular with little and grown up girls. Use candies to decorate cupcakes. You do not have to stop at floral patterns either. Get an assortment of sprinkles and sugars and let your creativity flow.
My favourite cupcake maker in Montreal, Michelle of Clever Cupcakes did the last two ideas. For a little boy, she created this amazing circus theme cupcakes. They are Vegan chocolate cupcakes with chocolate frosting topped with handmade fondant circus characters and circus tents.
For a Pink Princess birthday theme, Michelle handcrafted fondant pieces inspired by The Princess and The Frog tale. Michelle said on Flickr that she was inspired from another of my favourite cupcake maker, Blue Cupcake.
