Melt 1 stick of butter and mix with 2 cups of graham cracker crumbs.
Save a few crumbs for last step.
Pat into oblong pan.
Mix 2 cups powdered sugar, 2 sticks softened butter and 3eggs.
Has to be mixed for 20 minutes - "its worth it"
Pour over graham cracker.
Slice 5 to 7 bananas and put on above mixture.
Mix a 8 oz. container of cool whip and a 15 oz. can of crushed pineapple (drained).
Add this over the bananas.
Top with a few graham cracker crumbs.
This is very good - I have made it many times and it is always a big hit.
