Dusty Springfield's Banana Pudding

Dusty Springfield's Banana Pudding

1/2 cup flour
1 cup sugar
3 1/2 cups whole milk
2 egg yolks
1 tablespoon vanilla extract
1 box vanilla wafer cookies
6 or 7 bananas
2 1/2 cups heavy cream

Mix the flour, sugar and milk in a medium-size saucepan. Stir over low heat until the mixture thickens, then add the egg yolks. Cook for a minute more and then remove from heat. Add the vanilla extract and place a cover over the saucepan. Line a 2-quart dish with the cookies, add a layer of bananas and pour enough of the mixture from the saucepan to completely cover the bottom of the dish. Start again with the cookies, bananas, and mixture until all are used. Beat the heavy cream until thick. Pour over the top of the pudding. Refrigerate until ready to serve. Serves 8 or more.
