Mystery Ingredient

As its just after the first of the month, Sweetest Kitchen has announced the Mystery Box Cupcake Challenge for September.

This month, the mystery box challenge does not focus on an ingredient.  Instead, it asks bakers to create a cupcake based on a memory: childhood.  Sweetest Kitchen writes:

"this month you will need to create a cupcake that is based on your favorite childhood memories – this could be a particular flavor, or perhaps your favorite childhood dessert"

I've decided to participate in this month's challenge.  Because making a cupcake based on a childhood memory sounds like such a fun, creative experiment.  I'm not quite sure what I'm going to make, but I've got some ideas floating around in my head.  

If you were to create a cupcake from your childhood, what would it be?
