Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, cream together the softened vegan butter, brown sugar, and granulated sugar until light and fluffy.
Add the almond milk and vanilla extract to the butter-sugar mixture, mixing until well combined.
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
Gradually incorporate the dry ingredients into the wet mixture, stirring until a dough forms.
Fold in the chopped pecans, ensuring they are evenly distributed throughout the dough.
Scoop tablespoon-sized portions of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. The centers may look slightly underbaked; they will firm up as they cool.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
