Preheat your oven to 350°F (175°C). Gather your mixing bowls, measuring cups, and an ungreased baking sheet.

In a mixing bowl, combine the softened unsalted butter and powdered sugar. Beat until light and fluffy, about 2-3 minutes.

Add the vanilla extract along with the orange and lemon zest to the mixture, and mix on low speed until well incorporated, about 1 minute.

In a separate bowl, whisk together the all-purpose flour and salt. Gradually add this dry mixture to your creamed butter mixture, mixing gently.

Scoop portions of the dough and roll them into balls. Place on the ungreased baking sheet, spaced about 2 inches apart.

Roll each dough ball in granulated sugar for a sweet finish.

Place the baking sheet in the oven and bake for about 12 minutes until the edges are lightly golden and centers remain soft.

Let the cookies cool on the baking sheet for about 5 minutes, then transfer to a wire rack to cool completely.
