Preheat the oven to 350 degrees F (175 degrees C).

Cream coconut oil and brown sugar together in a bowl with an electric mixer until thoroughly mixed, about 5 minutes. Mix in almond milk and vanilla until incorporated, 1 to 2 minutes.

Whisk flour, baking powder, baking soda, and salt together in a bowl. Add the flour mixture to the almond milk mixture, stirring until combined; dough will be crumbly. Fold in chocolate chips.

Roll the dough into tablespoon-sized balls and place on ungreased or parchment-lined baking sheets. Flatten each ball out a bit with your palm, pressing any crumbs back together.

Bake in the preheated oven until the edges are golden brown and set, about 8 minutes.
