Who wants to be a millionaire?

Well, I think our co-op certainly does.....it is that time of year again.....birthday baking....and I have committed to another year of celebrating for my coworkers (aka being the Martha Stewart of the office). I let everyone offer suggestions and right now the votes are a hummingbird cake, Mississippi mud, cheese straws and Millionaire Pie. The millionaire pie is a must, considering it is this coworkers going away party, but the issue is we do not know what recipe was used last year or the one his godmother used to make. I have been Googling like crazy and have located countless options, and believe I am settling on one of the choices below:

Choice 1:
1 can Eagle Brand Milk
1 lg. can crushed pineapple (drain all juice)
2 1/2 tbsp. lemon juice
1/2 c. chopped pecans, fine
2 graham cracker crusts
1 lg. container of Cool Whip

Mix ingredients and pour into graham cracker crusts.

Choice 2:
2 baked 8 inch pie crusts
2 c. powdered sugar
1 stick (1/2 c.) butter, softened
1 lg. egg
1/4 tsp. salt
1/4 tsp. vanilla
1 c. heavy (whipping) cream
1 c. drained, crushed pineapple
1/2 c. chopped pecans

Cream together powdered sugar and butter. Add egg, salt and vanilla. Mix until light and fluffy. Spoon mixture evenly into pie crusts; chill.
Whip cream until stiff. Blend in pineapple and nuts. Spread on top of other mixture and chill thoroughly.

What do you all think, Choice 1 or 2? Or does anyone have a tried and true recipe?
