What are Funfetti Cupcakes?

Funfetti cupcakes are white cupcakes that have fun and colorful sprinkles. While we could make these from scratch, part of the nostaglia (for those of us who used to eat rainbow chip frosting and cupcakes) is using a box cake mix.

How to Make Better than Box Mix Cupcakes

  1. For starters, buy Duncan Hines white cake mix for this recipe. Every brand of cake mix is different, so the results won’t be the same if you use another brand.
  2. White cupcakes tend to be overly fluffy and fall apart easily. To make these funfetti cupcakes more substantial, we add sour cream and vanilla instant pudding mix. The result? A cupcake that is soft and fluffy but slightly cream too!

How to Make Funfetti Buttercream Frosting

For these fun cupcakes, we use the most amazing buttercream frosting! It’s always easy and delicious. As a side note, you can leave out the 2 ounces of cream cheese if you want a truly traditional buttercream frosting recipe.

Essential Baking Tools for These Cupcakes

  • Regular sized cupcake pan
  • Decorating Tip and piping bags
  • Cupcake Liners
  • For the sprinkles, you can use basic sprinkles from the grocery store, or get something really fun if it’s for a special occasion. The amount of sprinkles you add is completely up to you. It won’t affect the recipe unless you add copious amounts:)

  2. Hi, can this be made into a sheet cake?

    • Hi Karen, it definitely could, but you’d want to drop the baking temp by 25 degrees F and the baking time will be different. I hope this helps!
