Preheat oven to 375°F.Line cookie sheets with a silicone mat or parchment paper. In a large bowl, combine cake mix, eggs, oil, lemon juice, and zest. Stir well to combine.
Transfer the bowl to the refrigerator and chill the dough for 30 minutes. This makes the dough easier to work with.
Using a 1½ tablespoon cookie scoop, scoop the dough then roll it into the powdered sugar to form a ball. Place on the prepared cookie sheet.
Bake for 9-11 minutes until set but not browned. Let cool slightly on the cookie sheet before transferring them to a cooling rack to cool completely.
