Ingredients

  • 15 ounces white cake mix (1 box)
  • 5.9 ounces vanilla pudding mix (from box, not instant)
  • 4 eggs
  • 3/4 cup canola oil
  • 3/4 cup hot water
  • 1 cup  sour cream
  • 2 cups buttercream frosting
  • sprinkles

Instructions

  • Preheat oven to 325°F. Line a cupcake pan with cupcake liners and set aside.
  • In a large bowl, combine the cake mix and dry pudding mix. Stir until combined. Next mix in the eggs, canola oil and water. Finally mix in the sour cream.
  • Separate batter into 5 bowls. Add different colors of food coloring to each bowl and stir until smooth. Add one spoonful (about 1 Tablespoon) of each color to your cupcake liner (about 3/4 the way full).
  • Bake for 20-25 minutes or until they spring back when touched. Do not over cook. You can also test with a tooth pick to make sure the centers are cooked all the way through.
  • Remove from oven and allow cupcakes to cool on a cooling rack. Frost with buttercream frosting.
