Preheat the oven to 375 degrees. Combine the cake mix, eggs, oil, and a few drops of food coloring. You can make the color as prominent or muted as you like with your use of the food coloring. For this rosey pink color, I used 4 drops of red (liquid) food coloring. Refrigerate the dough for at least 30 minutes for fluffier cookies.
Roll tablespoon size balls of dough in the powdered sugar. A shallow pan works well for this. Place the balls on a parchment lined cookie sheet and bake for 9 to 11 minutes.
