Easy Turtle Bars

Prepare Your Baking Setup: Begin by preheating your oven to 350°F (175°C). This temperature ensures perfect baking of all layers.
Create the Shortbread Base: In a medium mixing bowl, thoroughly combine the flour and 1 cup brown sugar. Next, cut in ½ cup softened butter until the mixture resembles coarse crumbs, working quickly to maintain the ideal texture.
Form the Foundation: Press the crumb mixture evenly into an ungreased 9×13 inch baking pan, ensuring a level surface. Then, carefully arrange the pecan halves in a single layer over the crumb base.
Craft the Caramel Layer: Combine ⅔ cup butter and ½ cup brown sugar in a small saucepan. Heat over medium heat, stirring constantly until the mixture comes to a boil. Continue boiling and stirring for exactly one minute to achieve the perfect caramel consistency.
Layer Assembly: Pour the hot caramel mixture evenly over the pecans and crumb base, ensuring complete coverage. Use a spatula to spread it gently if needed.
Bake to Perfection: Place the pan in the preheated oven and bake for 18-20 minutes, or until you see the caramel layer bubbling vigorously.
Add the Chocolate Finale: Remove from the oven and immediately sprinkle the chocolate chips evenly over the hot caramel. Let them sit for 3-5 minutes to melt slightly, then spread into a smooth, uniform layer.
Cool and Cut: Allow the bars to cool completely on a wire rack, which typically takes about 2 hours. Once cooled, cut into squares using a sharp knife.
