Preheat oven to 350F. Grease cookie sheet or line with parchment paper. In a large bowl, combine applesauce, sugar, vanilla extract, and nondairy milk. In a small bowl, whisk flour, baking powder, salt, cornstarch, and a few dashes of ground cinnamon together. Transfer the dry mixture into the wet mixture in three batches. Stir until almost combined. Fold in chips. Drop spoonfuls on cookie sheet and bake for 7-10 minutes for a soft and light cookie or a few minutes more for a firmer cookie, being careful not to burn.
