Ingredients

  • 15.25 oz Vanilla cake mix We like Betty Crocker French Vanilla
  • 3.4 oz Instant vanilla pudding mix Optional
  • 4 Eggs
  • cup Vegetable oil
  • 1 cup Water
  • 6 tsp Food coloring Or more, depending on vibrancy (colors of your choice)
  • 2 cups Vanilla frosting Homemade or store bought
  • Sprinkles

Instructions

  • Preheat oven to 350 degrees.
  • Grease a 9x13 inch metal or foil cake pan.
  • In a large mixing bowl add cake mix and pudding mix (if using), eggs, oil, water and whisk until well incorporated.
  • Split half of the cake mixture into 3 small bowls.
  • Pour the other half of the cake batter into the prepared cake pan.
  • Place two to three drops of food coloring into each small bowl of cake batter and mix, wiping spoon clean between bowls.
  • Spoon each colored cake batter mixture on top of the plain vanilla cake batter in the pan. You do not need to worry about the pattern. Just drop the spoonfuls on top.
  • Using a butter knife, swirl the colorful batter so that colors mix together in a swirly pattern.
  • Bake uncovered in the oven for 22-25 minutes or until the cake appears golden brown and the edges pull away from the pan. The center should be set.
  • Allow cake to cool and frost with vanilla frosting of choice. Top with sprinkles.
