The bars are one of my all-time favorites, even if you're not a huge pecan pie fan. They're thick, rich, decadent, filling, salty-and-sweet. The pecans add amazing texture, crunch, and are a great contrast to the soft, tender shortbread crust, homemade salted caramel sauce, and chocolate. The bars are wonderfully satisfying, easy, no mixer is necessary, and are easier than making pie. I used roasted salted pecans and if yours are raw, toast them for 5 to 10 minutes in a 400F oven for enhanced flavor and sprinkle with a pinch of salt before using them in the recipe. While the bars bake, the easy caramel sauce made in the microwave thickens and the finished bars are loaded with luscious, drippy, salted caramel.
