In a large bowl, whisk together 1 cup granulated sugar and zests until fully incorporated. Whisk in melted butter, egg, egg yolk, orange juice, and vanilla until well combined.
In a medium bowl, whisk together flour, baking soda, and salt. Add flour mixture to sugar mixture in two additions, folding until well combined after each addition. Cover and refrigerate for 2 hours or overnight.
Preheat oven to 325°. Line 2 large rimmed baking sheets with parchment paper.
In a small bowl, place confectioners’ sugar. In another small bowl, place remaining ¼ cup granulated sugar.
Using a 1-tablespoon spring-loaded scoop, scoop dough and shape into balls. Roll in granulated sugar; roll in confectioners’ sugar. Place 2 inches apart on prepared pans.
Bake until edges are set and cracks have formed, about 12 minutes. Let cool completely on pans.
