Layers of the Earth

We made the earth and it's layers out of peanut butter, sugar, and flour.  We made balls and put them in the freezer.  After they were hard we took them out and we cut them in half and hollowed it out and filled it with jam and a chocolate chip.  We melted chocolate over the entire thing.  The chocolate was the earth's crust, the peanut butter was the mantle, the jam was the outer core and the chocolate chip was the inner core.

Then you can eat them.  They were really good.
