The big kids are at a good age to do things like this. It was fun. And I really do love twinkies, so it was a good excuse to buy a box (for the kids-right?).
Stuff you need:
-Marshmallows (cut in half)
-jelly bellies (cut in half)
-white frosting (as the glue)
So you cut a triangle shape piece midway out of the twinkie. Put your peep & steering wheel in. Glue marshmallows & jellybeans on the wheels using white icing.
