01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - Whisk together the flour, granulated sugar, baking soda, and salt in a medium mixing bowl.
03 - In a large mixing bowl, thoroughly mix the melted coconut oil or vegan butter, non-dairy milk, vanilla extract, orange juice, and orange zest until smooth.
04 - Gradually incorporate the dry mixture into the wet ingredients, stirring gently until a soft dough forms.
05 - Scoop dough using a tablespoon measure, roll each portion into a ball, then coat in the reserved granulated sugar.
06 - Arrange dough balls on prepared sheets, leaving about 2 inches between each. Gently press each ball flat with your palm or the bottom of a glass.
07 - Bake 9 to 11 minutes, until the edges are set but centers remain soft.
08 - Allow cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack until completely cooled.
