This classic Funfetti Frosting is super easy to make from scratch with a creamy vanilla frosting base and LOTS of cute and colorful sprinkles!
Sommer’s Recipe Notes
Why is it that sprinkles make us happy? Is it all the color… Or the nostalgic feelings from childhood?
No matter the reason, most of us are far more likely to reach for the cookie, doughnut, or cupcake with sprinkles on top, over any other option. I’m not sure who first decided to mix sprinkles into frosting to create the beloved “funfetti” frosting variation, but I’m so glad they did.
Homemade Funfetti Frosting is FUN to make, FUN to slather over birthday cake and even more FUN to eat! Not only do you get to have total control over the ingredients, vanilla buttercream frosting from scratch tastes like actual real butter, real cream, and real vanilla… Because that’s what is in it.
Why You’ll Love Funfetti Frosting
- Nostalgia in every bite – This deliciously creamy Funfetti Frosting is packed with nostalgic birthday cake flavors!
- Texture – This Funfetti frosting is super spreadable and perfect for decorating cakes, cookies and cupcakes. I also love to use this frosting as a dip for wafer cookies.
- Make-ahead friendly – Make this frosting recipe in advance and keep it handy for easy cake decorating.
Use this recipe for frosting all kinds of homemade cakes, cupcakes, or any baked treats that could use a POP of color and delicious vanilla flavor!
Ingredients and Tips
- Unsalted butter – It’s always better to start with unsalted softened butter and add your own salt.
- Powdered sugar – Otherwise known as confectioner’s sugar, this will help thicken and sweeten the frosting.
- Heavy cream – You can use half and half but it won’t have quite the same richness as heavy whipping cream.
- Vanilla extract – Use a pure high quality extract for the best taste.
- Rainbow Jimmies – Use any color and type of rainbow sprinkles you like, but do not use hard crunchy sprinkle-like candies.
Recipe Variations and Dietary Swaps
- Dairy-free – Use plant-based butter and a dairy-free cream alternative.
- Sprinkle colors – If you’re making a seasonally themed cake, use dyed sprinkles or seasonal sprinkles. Think black and orange for Halloween, green and red for Christmas, or pink or blue for baby showers.
- Food coloring – Use your favorite food coloring to make a bold frosting.
- Chocolate chips – Stir in mini chocolate chips.

Ingredients
- 1 1/2 cups unsalted butter, softened (3 sticks)
- 5-6 cups powdered sugar
- 1/4 cup heavy cream
- 2 teaspoons vanilla extract
- 1 pinch salt
- 4 ounces jimmies sprinkles
Instructions
- Make sure the butter is very soft. (Let is sit out at room temperature for 1-2 hours if needed.) Set out an electric mixer with a paddle attachment. Place the butter in the bowl of the mixer.
- Beat the butter on high for 2 minutes, until it's light and fluffy. Scrape the sides of the bowl with a rubber spatula.
- Turn the mixer on low and add in 2 cups powdered sugar. Beat until incorporated, then add in the heavy cream, vanilla extract, and salt.
- Scrape the bowl again. Then turn the mixer on low and slowly add in 3-4 more cups of powdered sugar. Once incorporated, turn on high for 1 minute to beat out all the clumps.
- Turn the mixer back on low and mix in the sprinkles. Stop once they look even. If you beat the sprinkles too long, they will start to break. (Mix the sprinkles in with a spatula if your mixer does not have a very low setting.)

It’s best to use jimmies or soft small candy sprinkles… Sugar sprinkles will disappear into the frosting, and hard candy sprinkles make the frosting difficult to eat.

Thaw overnight in the fridge, bring to room temperature (about an hour or so), and give it a good stir before using.
