Make the bottom (Karo) filling:

Mix the ingredients for the bottom in blender for 1 minute. Divide evenly into four parts and pour into pie shells.

Assemble the pie top:

Mix ingredients by hand. Using a spoon, drop spoonfuls of the mixture on top of the karo filling in the pie shells.

Bake at 350 for 45 – 50 minutes until the center is firm.

The two layers blend during the baking process, but you wind up with a firm, almost cake-like upper portion and a thin layer of liquid at the bottom, right above the pie crust.
