Preheat your oven to 180°C (350°F) and line a baking sheet with parchment paper.
In a medium bowl, whisk together flour, baking soda, and salt.
In another bowl, mix melted coconut oil, brown sugar, granulated sugar, non-dairy milk, and vanilla extract until well combined.
Add the dry ingredients to the wet ingredients and stir until just combined.
Fold in the vegan chocolate chips.
(Optional) Chill the dough in the fridge for 10 minutes for thicker cookies.
Scoop out tablespoons of dough and place them on the baking sheet about 5 cm apart.
Bake for 10–12 minutes, until edges are golden.
Let cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
