This recipe is from my grandmother (dad's mother). She was a farmer's wife and my memories of her are of her waking at the crack of dawn getting breakfast ready for all of the men (both family and workers) and then going and working the fields. Then coming back to make a big lunch and dinner for everyone. She was such a great country cook and this is one of her cherished recipes.
Mix flour, sugar, egg yolks, milk and salt in saucepan. Cook over medium heat, stirring constantly until thickened and bubbling.
Once thickened remove from stove and stir in butter and vanilla.
Use a large bowl and layer the pudding in the following manner: vanilla wafers on bottom of bowl, then 2 bananas sliced, then 1/2 of the cooked pudding.
Repeat layer with vanilla wafers, bananas and the rest of the pudding. Decorate top with remaining vanilla wafers. Cover with plastic wrap by laying the wrap right on top of the pudding and up to the edges of the bowl (this keeps a "skin" from appearing on the pudding).
Refrigerate until ready to serve. This can be topped with a whipped topping. Enjoy!
