2Beat the 2 eggs, sugar and cream cheese until smooth, spread over crust and bake for 20 minutes. Cool completely.
3In the mean time, mix the gelatin and water in a medium sauce pan and let stand. Blend the pumpkin, egg yolks, sugar, milk and pumpkin pie spice; add to gelatin and cook until thick, stirring frequently and let cool.
