This is a recipe that I got from my sister-in-law Parri. Sooo yummy.

baked 9" pie shell
1/2 cup water
2 Tbsp sugar
1 egg
1 Tbsp cornstarch
1 Tbsp sugar
zest of 1/2 lemon
1 1/2 Tbsp lemon juice
1 1/2 Tbsp butter
1 cup vanilla chips
8 ounces cream cheese
8 ounces cool whip

Put water and 2 Tbsp sugar in saucepan and bring to a boil. In a large bowl mix egg, cornstarch, 1 Tbsp sugar and zest of lemon. Slowly add hot to egg mixture in bowl to temper it. (If you pour too much hot water in the eggs cook). Then pour entire mixture back into pan. Heat until thickened, stirring often. Remove from heat and add lemon juice and butter. Stir until mixed.

Pour 2/3's of filling into bowl. Add vanilla chips to filling remaining in pan. Stir until chips are melted. Put cream cheese in bowl. Add filling with vanilla chips to cream cheese and beat together. Spread this mixture in bottom of pie shell. Spread remaining 2/3's of lemon filling on top. Chill for 2 hours. right before serving top with whip cream or cool whip.
