The latest snack rage for my 7 year old is a new "invention" of hers.
She pushes "corn on the cob holders" into each end of an apple (you could use popsicle sticks) Then spreads a generous ammount of peanut butter all around the outside of the apple, and then presses on mini marshmallows and/or chocolate chips. (She prefers a Granny Smith apple, but you could use your favorite variety). She proceeds to enjoy her creation as you would an "ear of corn"!
(This snack must be served with A LOT of napkins.)
