1. CRUST: Preheat oven to 350*F. 2. Combine the flour, brown sugar, and butter in a large bowl; beat with an electric mixer on medium speed, scraping bowl often, until the mixture is crumbly (2-3 minutes). 3. Firmly press into the bottom of an ungreased 13x9" baking pan; sprinkle the nuts evenly over the top. 4. FILLING: Combine the butter and brown sugar in a 1-quart saucepan; cook over medium heat, stirring constantly, until the mixture comes to a full boil (about 4-5 minutes). 5. Boil, stirring constantly, until a candy thermometer registers 242*F (or until a small amount dropped into ice water forms a firm ball), about 2-3 minutes. 6. Pour the mixture over the nuts and crust; bake for 18-20 minutes, or until caramel is bubbly. 7. Immediately sprinkle with butterscotch and chocolate chips; let stand 5 minutes. 8. Swirl the chips as they melt, leaving some whole for a marbled effect. 9. Cool completely before cutting into bars. ---------------------------------------------------------------------------
