Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Cream together softened unsalted butter, granulated sugar, and light brown sugar until smooth and fluffy, about 2-3 minutes.

Beat in one egg and vanilla extract until fully combined, scraping the sides of the bowl.

In a separate bowl, whisk together flour, baking soda, and salt. Gradually add it to the wet ingredients until just combined.

Fold in quick oats, chocolate chips, and chopped pecans until evenly incorporated.

Scoop dough balls onto the lined baking sheet, leaving 2 inches between each.

Bake for 8–9 minutes until edges are golden brown and centers are soft.

Cool on the baking sheet for 10–15 minutes before transferring to a wire rack.
