Oatmeal Butterscotch Bars

0 Preheat oven to 350° and line a 13x9 pan with foil. Grease the foil and set aside.
1 In a small bowl, combine flour, oats, and salt. Set aside.
2 Put the butterscotch chips in a large bowl.
3 Heat butter in a small saucepan over medium-low heat until nutty brown in color. About 10 minutes. You'll see a definite change- it will go from bubbling and noisy to foaming and quiet. I stir with a whisk regularly to prevent burning.
4 Pour over butterscotch chips and stir until chips are completely melted and smooth.
5 Stir in sugar and mix until dissolved.
6 Add the vanilla and the egg and mix well.
7 Stir in the flour mixture.
8 Spread into prepared pan and bake for 18-20 minutes.
