Preheat your oven to 180°C (350°F) and line a baking sheet with parchment paper.
In a mixing bowl, cream together the softened vegan butter or coconut oil, granulated sugar, and brown sugar until well combined and creamy.
Add in the vanilla extract and unsweetened applesauce, and mix until incorporated.
In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until a dough forms. Be careful not to overmix.
Fold in the vegan chocolate chips or chunks until they are evenly distributed throughout the dough.
Using a spoon or your hands, form the dough into cookie dough balls and place them on the prepared baking sheet, leaving some space between each cookie.
Gently flatten each cookie with your fingers or the back of a spoon.
Bake in the preheated oven for about 12 minutes, or until the edges are golden brown.
Remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.Enjoy your delicious vegan chocolate chip cookies!
