Preheat the oven to 350°F and line two baking sheets with parchment paper.

In a medium bowl, whisk together the flour, baking powder, and salt, then set aside.

In a large bowl, cream the butter and granulated sugar until light and fluffy.

Beat in the egg, lemon zest, lemon juice, vanilla extract, and a few drops of pink food coloring until evenly mixed.

Gradually add the dry ingredients to the wet ingredients and mix just until a soft dough forms.

Scoop the dough into tablespoon-sized balls and roll each one in powdered sugar until fully coated.

Place the dough balls on the prepared baking sheets about 2 inches apart.

Bake for 10–12 minutes, until the cookies are puffed, cracked on top, and just set around the edges.

Let the cookies cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely.
