Preheat oven to 350°F (175°C). Line baking sheets with silicone mats or parchment paper.

In a medium bowl, whisk together flour, cocoa powder, salt, and baking soda. Set aside.

Using an electric mixer, cream softened butter with both brown and granulated sugars for 2-3 minutes until light and fluffy.

Beat in egg and vanilla extract until fully combined.

Gradually add flour mixture to butter mixture, mixing on low speed until almost combined.

Fold in chocolate chips, caramel pieces, and pecans. Don't overmix.

Using a cookie scoop, form dough balls (about 3 tablespoons each). Press extra caramel pieces, pecans, and chocolate chips onto the outside of each ball.

Bake for 10-14 minutes until edges are set but centers still appear slightly soft.

Cool on baking sheet for 10 minutes before transferring to wire rack.
