Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a large mixing bowl, combine the softened unsalted butter and powdered sugar. Cream together until light and fluffy.

Add vanilla extract, orange zest, and lemon zest to the mixture and mix on low until well combined.

Gradually add all-purpose flour and salt. Blend until a soft dough forms.

Scoop dough onto baking sheets, flatten each ball, and sprinkle with granulated sugar.

Bake for 10-12 minutes until edges are lightly golden. Watch closely to avoid overbaking.

Cool cookies on baking sheets for 5 minutes before transferring to a wire rack.
