For fun or for no reason at all! I did this with the traditional sugar overload of ice-cream and candy, but you can do this with yogurt, graham crackers & cool whip, bread & butter, cupcakes or giant cookies.
You do not by any means have to use all the sugar I did, use happy cereal, nuts, dried fruit and fresh fruit instead. Always, always, always remember the age of your kidlets and what they can and can not eat. I know YOU know this but just in case your wee ones have a friend who is younger make sure to think age appropriate sweets. it's a no brainer I know but we all forget sometimes.
I had wanted to do this in pretty, happy bowls or cups but forgot to bring my own and was at the work house so I decided to use a happy fun plastic tray and cupcake liners. Oh how I love me a cupcake liner! So have fun, get creative and as always, take pictures!
