Preheat oven to 350°F and line a baking sheet with parchment paper.
In a large bowl, whisk together the melted vegan butter, brown sugar, and granulated sugar until smooth.
Add the applesauce and vanilla extract and stir until fully combined.
Add the flour, baking powder, and baking soda. Mix until a soft cookie dough forms and no dry streaks remain.
Fold in the mini chocolate chips until evenly distributed.
Scoop about 2 teaspoons of dough and roll into small balls. Place on the prepared baking sheet with a little space between each cookie.
Bake for 9 minutes, until the bottoms are lightly golden and the tops look set.
Let the cookies cool on the baking sheet for a few minutes before transferring to a wire rack.
