Set oven at 350 degrees F, to preheat. Grease 11 x 7 x 1 1/2 pan. Sift flour and salt. Add oatmeal. Combine butter, sugars, vanilla and egg in large Mixmaster bowl. Cream on No. 7 speed for 2 minutes. Add flour mixture. Beat on No. 3 speed about 1 minute. Bake about 25 minutes. Cool 10 minutes. Melt chocolate over hot water, stirring until smooth. Spread over backed batter. Sprinkle with nuts. Cool in pan. Cut in bars. Makes 2 doz.
My pan was slightly larger so my bars turned out thinner. I also had to adjust the cooking time to 18 minutes. With the heat wave we're having, my chocolate didn't want to set so I have been keeping them in the fridge and they are wonderfully delicious! Melting a little peanut butter with the chocolate would be tasty, too. :)
