These bars were Uncle Peter’s favorite when we used to send him food while he was in college. They mail well (and don’t crumble).
Heat oven to 350 degrees. Grease 9” x 13” pan. In large bowl, mix crust ingredients at low speed until crumbly. Press 1/2 mixture (about 3 cups) into pan (not easy, but SO worth it). Bake 12 minutes. Sprinkle warm base with chocolate chips and nuts. Combine caramel topping and 3 tablespoons flour, and drizzle over chocolate chips and nuts. Evenly distribute remaining ‘crust’ on top using flattened spoonfuls. Return to oven and bake 20-25 minutes, until golden. Cool completely. Cut into bars.
Makes 36 bars.
