Preheat your oven to 350°F. Line rimmed baking sheets with unbleached parchment paper and set it aside.

In a large bowl, place the flour, xanthan gum, baking powder, baking soda, salt, and granulated sugar, and whisk to combine well.

Add the brown sugar, and mix to combine, breaking up any lumps in the brown sugar.

Create a well in the center of the dry ingredients and add the coconut oil. Mix to distribute the coconut oil evenly, pressing down on the mixture with the back of the mixing spoon.

Add the applesauce, milk, and vanilla, and mix to combine. The cookie dough may seem a bit crumbly.

Divide the cookie dough into 20 to 21 portions.

Roll each piece of dough tightly into a ball about 1 1/2 inches in diameter.

Press each of the balls of dough into a disk about 1/2-inch thick and place about 1 1/2 inches apart on the prepared baking sheets.

Press a few reserved chips, if any, into the top of each shaped cookie.

Place the baking sheets, one at a time, in the center of the preheated oven.

Bake until the cookies are lightly golden brown all over and set in the center (10 to 12 minutes).

Remove from the oven and allow the cookies to cool on the baking sheet for about 5 minutes or until firm before transferring to a wire rack to cool completely.
