01 - Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together all-purpose flour, baking soda, baking powder, and salt until well mixed.
03 - In a large bowl, beat vegan butter and granulated sugar using an electric mixer or whisk until light and creamy, about 2 minutes.
04 - Incorporate plant-based milk, vanilla extract, fresh lemon juice, and lemon zest into the creamed mixture. Mix until fully combined.
05 - Gradually add the dry ingredients to the wet mixture, stirring until a soft cookie dough forms. Avoid overmixing.
06 - Scoop tablespoons of dough, roll into balls, and coat each ball in granulated sugar.
07 - Place cookie balls about 2 inches apart on the prepared baking sheets. Gently flatten each ball with your fingers or the bottom of a glass.
08 - Bake for 10 to 12 minutes, or until the edges are set and the tops appear slightly crackled.
09 - Allow cookies to cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
