  • Large Mixing Bowl


  • 15.25 oz box white cake mix
  • 1/3 cup vegetable oil
  • 2 large eggs
  • food coloring of choice
  • 1/2 cup granulated sugar


  • Add the cake mix, vegetable oil, and eggs to a large bowl and mix them together until combined.
  • Divide the dough evenly into 5 different bowls.
  • Mix each portion of dough with the desired food coloring, until evenly colored. (We used reen, yellow, red, orange and blue).
  • Cover the bowls and place the dough in the fridge for 45 minutes.
  • Preheat the oven to 350 degrees Fahrenheit. Line a baking sheet with parchment paper.
  • Portion out a dollop of each color of cookie dough. Then use a cookie scoop to scoop the dough up and roll the balls together to swirl the colors together.
  • Place the granulated sugar into a small bowl, and roll each of the cookie dough balls into the sugar.
  • Place the balls onto the prepared cookie sheet, about 2 inches apart.
  • Bake the cookies for 8 to 9 minutes. They will look puffy and slightly underdone (but will continue cooking on the baking sheet out of the oven.)
  • Remove the pan of cookies out of the oven and let the cookies cool on the baking sheet for about 5 minutes. Then transfer them to a wire rack to cool completely.
