1/3 c. all-purpose flour
dash of salt
4 eggs, separated (at room temperature)
2 c. milk
1/2 tsp. vanilla extract

Combine 1/2 sugar, flour and salt in top of double boiler; stir in egg yolks and milk. Blend well. Cook, uncovered, over boiling water, stirring constantly until thickened. Reduce heat and cook, stirring occasionally, for 5 minutes. Remove from heat; add vanilla. Spread small amount on bottom of 1 1/2-quart casserole; cover with layer of vanilla wafers. Top with layer of sliced bananas. Pour about 1/3 of custard over bananas; continue to layer wafers, bananas and custard to make 3 layers of each, ending with custard. Beat egg whites until still but not dry. Gradually add remaining 1/4 cup sugar and beat until stiff peaks form. Spread to cover surface or top with Cool Whip.
