Preheat the oven to 350°F (175°C). In a mixing bowl, whisk together the flour, baking powder, and salt.

In another bowl, cream the softened butter and granulated sugar until light and fluffy. Beat in the egg, lemon zest, rosewater, and vanilla extract until well combined.

Gradually add the dry ingredients to the wet ingredients, mixing until a soft dough forms.

Roll the dough out on a floured surface to about 1/4 inch thick. Use cookie cutters to cut out shapes and place them on a baking sheet lined with parchment paper.

Bake in the preheated oven for 10-12 minutes or until the edges are lightly golden. Remove from the oven and let cool on the baking sheet for a few minutes before transferring to a wire rack.

Once cooled, dust the cookies with powdered sugar before serving.
