Combined with fluffy buttercream frosting, the result is a cake that’s as fun to look at as it is to eat.

How to Make Funfetti Cake from Scratch
Step 1: Prepare the Cake Pans
Preheat your oven to 350°F (175°C).
Grease and line two 8-inch round cake pans with parchment paper.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together:
- Flour
- Baking powder
- Salt
Set aside.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the butter and sugar until light and fluffy, about 3–4 minutes.
This step helps create a soft, airy cake.
Step 4: Add Eggs and Vanilla
Beat in the eggs one at a time.
Mix in the vanilla extract until fully combined.
Step 5: Alternate Dry Ingredients and Milk
Add the flour mixture in three additions, alternating with the milk.
Begin and end with the dry ingredients.
Mix just until combined.
Step 6: Fold in the Sprinkles
Gently fold in the rainbow sprinkles using a spatula.
Avoid overmixing to prevent the colors from bleeding.
Step 7: Bake the Cakes
Divide the batter evenly between the prepared pans.
Bake for 28–32 minutes or until a toothpick inserted into the center comes out clean.
Allow cakes to cool completely before frosting.
Make the Buttercream Frosting
Step 1: Beat the Butter
Beat softened butter until creamy and smooth.
Step 2: Add Powdered Sugar
Gradually add powdered sugar, mixing well after each addition.
Step 3: Add Vanilla and Cream
Mix in:
- Vanilla extract
- Heavy cream
- Salt
Beat until light and fluffy.
Add additional cream if needed for a spreadable consistency.
Assemble the Cake
Step 1: Level the Cake Layers
Trim the tops if necessary for even layers.
Step 2: Add Frosting Between Layers
Spread a generous layer of buttercream on the first cake layer.
Step 3: Frost the Entire Cake
Place the second layer on top and frost the top and sides.
Step 4: Decorate
Cover the top with extra rainbow sprinkles for a festive finish.
Tips for the Best Funfetti Cake
Use Jimmies Sprinkles
Jimmies hold their shape and color best during baking.
Don’t Overmix
Too much mixing can cause the sprinkles to bleed.
Use Room-Temperature Ingredients
This helps create a smoother batter and fluffier cake.
Cool Completely Before Frosting
Warm cake layers can melt the frosting.
Measure Flour Correctly
Too much flour can make the cake dense.
Fun Variations
Chocolate Funfetti Cake
Replace part of the flour with cocoa powder.
Funfetti Cupcakes
Use the same batter to make cupcakes.
Bake for 18–20 minutes.
Funfetti Layer Cake
Create three thinner layers for a taller celebration cake.
Cream Cheese Frosting Version
Use cream cheese frosting instead of buttercream for a tangy twist.
Confetti Sheet Cake
Bake the batter in a 9×13-inch pan for easy serving.
Storage Tips
Store the cake covered at room temperature for up to 2 days.
For longer storage, refrigerate for up to 5 days.
Allow chilled cake to come to room temperature before serving for the best texture.
