Everybody's Grandma's Banana Pudding

I found my copy of this recipe recently (as dictated to me by my grandma) and I was going to title it "My Grandma's Banana Pudding" but I'm pretty sure it's the same recipe everyone's grandmas used (since I think it originally came from the back of a Nilla Wafers box).

2/3 cups sugar
1/4 cup flour

Mix flour and sugar together and add

2 eggs, beaten
2 cups milk
1 Tbsp butter
dash salt

Mix and cook in a double-boiler until it thickens.

Remove from heat and add 1/2 tsp vanilla extract.

Line the bottom of a bowl with sliced banana rounds and pour on the pudding. Top with Nilla Wafers and chill before serving.

And now I really want to make some.
