  • Cake mix– Funfetti cake mix. If you don’t have Funfetti or other confetti cake, you can use yellow cake mix and extra sprinkles.
  • Butter– Melted
  • Eggs
  • Heavy cream– Don’t use regular milk or half and half. The heavy cream is the secret ingredient to giving these the best texture and making them taste totally homemade!
  • White chocolate– Chopped
  • Sprinkles– Rainbow sprinkles for maximum birthday cake vibes.
