Banana Split Pie

My gramma always used to make this pie.  It is delicious, but this is the first time that I have made it - the raw eggs always made me hesitate before.  I just made sure to keep it super cold all of the time!

Banana Split Pie

1 stick butter
1 1/2 cup powdered sugar
2 eggs
1 tsp vanilla
2 bananas - sliced
1 T lemon juice
1-2 square german sweet chocolate (green foil) - shaved
1/4 cup walnuts - chopped
1 pie crust - baked

Bake single pie crust according to box directions.  Beat butter and powdered sugar together in a bowl. Add one egg at a time, beating for 3 minutes after each addition. Stir in vanilla.  Slice the bananas and sprinkle with lemon juice to prevent browning. Stir in all but 12 slices. Stir in shaved chocolate and pour into pie shell. Garnish with walnuts and two banana slices per slice of pie. Refrigerate at least 2-3 hours. Best if eaten the same day.
