Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.

In a large mixing bowl, whisk together eggs, vegetable oil, and vanilla extract until frothy.

Pour the white cake mix into the wet ingredients and mix until a thick dough forms.

Divide the dough into two bowls; color one with red food coloring and the other with green, mixing well.

Chill the colored dough in the refrigerator for at least 30 minutes.

Scoop and roll the dough into balls, then coat them generously with powdered sugar.

Bake the cookies for 9 to 11 minutes, until puffed and cracked on top.

Allow to cool slightly on the baking sheet before transferring to a wire rack.

Once cooled, serve or store in an airtight container.
