Mix eggs, oil and cake mix in a large bowl. Separate dough into two equal amounts.
In small bowls dye one part red and the other part green. The dough has play dough-like consistency, so I found it easiest to mix the colors by hand.
Refrigerate dough for at least 30 minutes to create fluffier cookies.
Roll tablespoon size balls of dough in powdered sugar and place on a Silpat or parchment lined cookie sheet.
Bake for 9-11 minutes at 375 degrees.
