Preheat the oven to 375 degrees. Line several baking sheets with parchment and set aside.

Combine the cake mix, eggs, and melted butter in a large bowl. Mix together using a firm rubber spatula until all of the dough is smooth and thick.

In a small bowl, combine the confectioner’s sugar and cornstarch. Stir together with a fork.

Scoop the dough using a medium cookie scoop. Roll each scoop in the sugar mixture to coat.

Place coated dough balls on the prepared baking sheet.

Bake each baking sheet in its own batch for 9-12 minutes.

Remove and let cool on the baking sheet for several minutes before transferring to a wire rack to finish cooling.
