This dessert is a reflection of a simpler time. Banana pudding uses few ingredients. Pure ingredients. Bananas, vanilla wafers, milk and eggs. All layered together.
In a 3 quart saucepan or medium size, add the flour, sugar and salt. Whisk together. Next add the egg yolks and milk. Whisk all together. On medium heat, constantly whisk the mixture until it comes to a low boil, just until it starts to bubble. You want it thick. Remove from the heat. Stir in the vanilla.
In a 2 quart bowl or casserole dish, layer the vanilla wafers on the bottom till covered, then add a layer of sliced bananas followed by a layer of pudding. Continue for two more layers or until you run out of pudding. Crush some vanilla wafers and sprinkle on top of the pudding.
Chill for a minimum of two hours before serving.
Keep covered and stored in the refrigerator, up to 3-4 days.
