Preparation Steps

• Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
• In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
• In a large bowl, beat butter and 1 1/2 cups sugar with an electric mixer until light and fluffy, about 3 minutes.
• Beat in egg, lemon zest, lemon juice, and vanilla extract until combined.
• Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined.
• Roll dough into 1-inch balls, then roll each in the remaining 1/4 cup sugar to coat.
• Place balls 2 inches apart on prepared baking sheets.
• Bake for 8–10 minutes, or until edges are lightly golden. Centers will look soft.
• Cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely.
