Funfetti Cake and Buttercream Frosting

So you want cake… but not just any cake. You want the kind of cake that screams celebration even if it’s just Tuesday and you survived your inbox. Same energy.

Funfetti Cake with Buttercream Frosting is pure joy in dessert form. It’s soft, fluffy vanilla cake loaded with rainbow sprinkles and topped with dreamy, creamy frosting. It tastes like birthday parties, sleepovers, and absolutely zero adult responsibilities.

Why This Recipe is Awesome

First of all, sprinkles. That’s it. That’s the reason. They don’t add flavor, but they add vibes—and sometimes that’s enough.

Second, the texture is unreal. The cake stays moist and tender, and the buttercream is silky and sweet without being overwhelming. It’s classic vanilla, but upgraded with personality.

And here’s the kicker: it’s not complicated. Cream butter and sugar. Add eggs. Mix. Bake. Frost. Done. Use room-temperature ingredients for a smoother batter and fluffier cake.

It’s also crowd-proof. Kids love it. Adults secretly love it more.

Ingredients You’ll Need

For the cake:

• 2 1/2 cups all-purpose flour
• 2 1/2 teaspoons baking powder
• 1/2 teaspoon salt
• 3/4 cup unsalted butter, softened
• 1 3/4 cups granulated sugar
• 4 large eggs
• 1 tablespoon vanilla extract
• 1 cup whole milk
• 3/4 cup rainbow sprinkles (use jimmies, not nonpareils)

For the buttercream frosting:

• 1 cup unsalted butter, softened
• 3–4 cups powdered sugar
• 2–3 tablespoons heavy cream or milk
• 1 teaspoon vanilla extract
• Pinch of salt

Optional: extra sprinkles for topping (because obviously).

Step-by-Step Instructions

1. Preheat and Prep
   Preheat your oven to 350°F (175°C). Grease and line two 8-inch cake pans with parchment paper.
2. Mix Dry Ingredients
   Whisk flour, baking powder, and salt in a bowl. Set aside. Simple.
3. Cream Butter and Sugar
   Beat softened butter and sugar together until light and fluffy. This takes about 3–4 minutes. Don’t rush it—this step builds texture.
4. Add Eggs and Vanilla
   Add eggs one at a time, mixing well after each. Stir in vanilla extract.
5. Combine Wet and Dry
   Alternate adding dry ingredients and milk to the batter. Mix just until combined. Overmixing makes dense cake.
6. Fold in Sprinkles
   Gently fold in rainbow sprinkles. Use jimmies so they don’t bleed color into the batter.
7. Bake
   Divide batter evenly between pans. Bake 25–30 minutes until a toothpick comes out clean. Cool completely before frosting.
8. Make the Buttercream
   Beat butter until creamy. Add powdered sugar gradually. Mix in vanilla, salt, and cream until smooth and fluffy.
9. Frost and Decorate
   Spread frosting between layers and over the top. Add extra sprinkles like you mean it.

Common Mistakes to Avoid

Using cold ingredients
Cold butter won’t cream properly. Let everything come to room temp.

Overmixing the batter
Too much mixing equals dense cake.

Using the wrong sprinkles
Nonpareils bleed. Stick with jimmies.

Frosting a warm cake
It melts. Let it cool completely.

Skipping parchment paper
It makes removal easier and stress-free.

Alternatives & Substitutions
