Either way, but the pudding has to be made from scratch, wife's is darn good.

Recipe?

From the source :

Banana Pudding
4 T flour
1 c. sugar
1 t salt
3 egg yolks
2 c milk
2 T butter
1 t vanilla

In a saucepan, put flour, sugar and salt and stir; add lightly beaten egg yolks and milk; Cook until pudding thickens stirring constantly on medium heat. Remove from heat and stir in butter and vanilla. Let cool; in a large bowl, place a layer of vanilla wafers and then a layer of sliced bananas and then about a 1/3 of the pudding; repeat the layers two more times. I usually add extra vanilla wafers on top as we like a lot of vanilla wafers. Note: You can use the above recipe and add coconut and place in a cooked pie shell for coconut pie. I use the egg whites to make a meringue and top with coconut.

Bananas, or it ain’t banana pudding.
