Preheat oven to 350°F. In a small bowl, sift together flour, baking soda, and salt. Set aside.

In a medium bowl, beat butter and brown sugar until creamy.

Add egg and vanilla to creamed sugar and butter mixture.

Gradually add flour to creamed mixture.

Stir in 1⁄2 cup semi-sweet chocolate chunks and pecans.

Chop your candy bar pieces and mix into batter.

Use a large cookie or ice cream scoop and place cookies 3” apart on parchment lined baking sheet as these will spread.

Lightly press cookies to flatten. Press the reserved 1⁄2 cup chocolate chunks and reserved 1/3 chopped pecans into tops of cookies.

Bake 14 minutes. Cookies should be slightly under baked.

Cool 5 minutes on baking sheet. Transfer to wire rack to cool.
