Preheat the oven to 350F then line a square 8x8 inch baking pan with parchment paper and set aside. Make sure to leave some parchment overhand to make the pulling-out process a whole lot easier.
In a large mixing bowl, cream the butter and brown sugar together. Add the egg, vanilla extract, and Karo® Syrup to the butter mixture and mix again to combine. Make sure to scrape down the sides with a rubber spatula as you go.
½ cup butter, ¾ cup brown sugar, 1 egg, ¼ cup Karo® Syrup, 1 teaspoon vanilla extract
Fold in the dry ingredients, so the all-purpose flour, baking soda, and salt making sure not to overmix. Fold in the toasted chopped up pecan and the chocolate chips then pour the batter into the prepared pan.
1 & ¼ cups all-purpose flour, 2 tablespoons cornstarch, ½ teaspoons salt, ¼ teaspoon baking powder, ½ cup pecans, ⅓ cup chocolate chips
Bake in the preheated oven for 23-28 minutes or until they are golden brown and a wooden skewer inserted in the center comes out with a few crumbs. Allow the bars to cool down a little then transfer them to a wire rack to cool down fully before slicing into them and enjoy!
