Layers of the Earth Model You Can Eat

STEP 1: THE CRUST: Spray a medium mixing bowl with non-stick spray. Mix together 2 cups of crushed graham crackers with 4 Tab. of powdered sugar and 1/2 cup of melted butter. Press into the sides of the bowl, forming an even layer. This is the crust of the earth, which is easy for kids to remember because it is just a graham cracker pie crust. Put this in the freezer until firm.
STEP 2: THE MANTLE: Chop about 1/2 cup peanuts and stir into about a half-gallon of chocolate ice cream. Another alternative would be to buy a flavor that already has peanuts in it. Remove the crust from the freezer and gently line the frozen crust with the ice cream mixture. Return to the freezer until firm.
STEP 3: THE OUTER CORE: Swirl orange, red and yellow sherbets to get a "flaming" effect of melted iron and other elements. (Sometimes you can already find sherbet swirled.) You will only need a pint or less of this. Mix in a few M & M's. Remove the frozen layers from the freezer and gently spread the sherbet in (about 1' thick), leaving a round hole in the middle for the next layer. Put it back in the freezer.
STEP 4: THE INNER CORE: Since this layer is made up of mostly solid iron, you will need to color about a half-pint of vanilla ice cream gray. We used black cake decorator's coloring. You could also use equal amount of red and green food colorings. Mix in twice as much M & M's as you did in the Outer Core. Remove the frozen layers from the freezer and fill the cavity with the vanilla ice cream mixture. Return to the freezer until firm.

To serve, cut it into fourths. Remove one quarter at a time. Slice each quarter like a cake so that each serving shows the layers.

  1. Oh my goodness. That is the yummiest Earth ever! We made plasticene models, inspired by that beautiful pin from Meet the Dubiens. It was much more difficult and required a lot more plasticene than I'd expected!
