Step 1

Place a layer of Nilla Wafers in the bottom of a medium-sized mixing bowl. Slice a banana over the top. Repeat two more times with another layer of wafers and the remaining bananas.

Step 2

In a medium saucepan (or double boiler) on medium-low heat, add all ingredients except for the vanilla extract. Stir well with a wire whisk. Allow to cook, stirring constantly to prevent scorching, until thickened - about 15 minutes.

Step 3

Add in vanilla and stir. Immediately pour over wafers and bananas.

Step 4

Beat egg whites until foamy. Add sugar. Continue beating at high speed until soft peaks form. Pour onto the top of the pudding and spread to the edges to seal well. Bake at 325 for 10 minutes or until the top is golden.
