Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a large mixing bowl, beat the softened vegan butter, granulated sugar, and brown sugar together with a hand mixer or whisk until creamy and well combined, about 2 minutes.
Add the unsweetened applesauce and vanilla extract to the butter mixture, and mix until smooth and evenly incorporated.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing just until no flour streaks remain.
Fold in the vegan chocolate chips with a spatula until evenly distributed throughout the dough.
Scoop heaping tablespoons 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 and the centers are set.
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
