01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a small bowl, whisk together the flour, baking soda, baking powder, salt, and dried chamomile flowers until evenly distributed. Set aside.
03 - In a large bowl, whisk the granulated sugar and melted coconut oil until well combined. Add the non-dairy milk and vanilla extract, whisking until the mixture is smooth and creamy.
04 - Gradually fold the dry ingredient mixture into the wet ingredients using a spatula, mixing until just combined. Be careful not to overmix.
05 - Scoop tablespoon-sized portions of dough and roll into balls. Roll each ball in the extra granulated sugar, coating evenly.
06 - Place the dough balls on the prepared baking sheets, spacing them about 2 inches apart. Gently flatten each ball with your palm or the bottom of a glass.
07 - Bake for 10 to 12 minutes, or until the edges are just turning golden and the centers appear set.
08 - Allow the cookies to cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
