Frosting for this Funfetti Cake Recipe

This Funfetti cake recipe is paired with a delicious vanilla buttercream frosting that is so easy to make (you’ll want to make it for other recipes, too). You could change it up and use chocolate frosting instead, but I love how the sprinkles pop with the color of the white frosting. You can also tint the frosting in different colors using gel food coloring. 

The frosting is made with just 5 simple ingredients and spreads perfectly onto the cake for even layers and perfect coverage on the outside of the cake.

Here are some tips for creating the layers of frosting between the cake:

1. Level the Cake Layers: Before adding frosting between the layers, ensure that each cake layer is leveled. You can use a serrated knife or a cake leveler to trim off any uneven tops. This will help the layers stack evenly and prevent the cake from leaning.
2. Cool the Cake Layers Completely: For easier handling, ensure the cake layers are completely cooled before adding frosting. If they are still warm, the frosting will start to melt.
3. Don’t Overdo the Frosting: It’s important not to use too much frosting between the layers, as this can cause the layers to slide or the cake to become overly sweet. I recommend measuring 3/4 to 1 cup of frosting for each layer.
4. Press Layers Gently: As you stack each layer on top of the frosted one below, press down gently to help adhere the layers together and evenly distribute the frosting.

How to Make Homemade Funfetti Cake

Tired of boring birthday cakes? This Funfetti cake is the upgrade you need! Make it once, and it’s likely to become a family tradition. Get the full recipe with ingredients in the recipe card below. Here are the easy steps:

1. Prep oven and pan. Preheat the oven to 350º F. Grease two or three 8 inch springform cake pans with butter (butter the sides and bottom) and line each pan with a parchment paper rounds for easy cake removal. Set aside. 

2. Mix dry ingredients. In a small mixing bowl combine the flour, baking powder, baking soda, salt and sprinkles.
3. Start to mix wet ingredients. In a large mixing bowl combine the butter, sugar, and vegetable oil, beat using an electric mixer, 1-2 minutes until fluffy.
4. Mix in remaining wet ingredients. Add in the eggs, sour cream, milk, and vanilla extract. Beat with the electric mixer.
5. Combine wet and dry ingredients. Gradually add the flour mixture to the wet ingredients, mixing just until the flour is incorporated.

6. Add batter to pans. Evenly divide the batter among the pans. If using 2 pans, that’s 3 cups of batter per pan, if using 3 pans, that’s 2 cups of batter per pan. If you have bake even cake strips, secure them around the outside of the pans. 
7. Bake. Bake 2 pans for 40-50 minutes or 3 pans for 32-37 minutes or until a toothpick inserted in the center comes out clean.
8. Cool. Allow the cakes to cool for 20-30 minutes in the pans, then use a small spatula to loosen the cake from the edge of the pan. Remove the cake from the pans and allow them to cool completely on a cooling rack.  

Frosting

1. Start mixing ingredients. In a mixing bowl, combine the butter, vanilla extract and salt, beat using an electric mixer until fluffy, 1-2 minutes.
2. Mix in powdered sugar. Gradually add the powdered sugar, mixing on low until combined.
3. Add color (optional). If you want to add food coloring, do so now.
4. Taste and adjust as needed. Taste as needed to determine if you want more powdered sugar. If the frosting becomes too thick, add 2-4 tablespoons of milk or heavy cream.
5. Add cream for fluffier frosting. If you want an extra fluffy frosting, add in 1/4 cup heavy whipping cream when adding the last bit of powdered sugar. Whip for 3-4 minutes.

Assemble the Cake

1. Level cakes. If needed, level the cooled cakes using a cake leveler or serrated knife.
2. Frost and layer cakes. Spread a small amount of frosting on the bottom of your cake plate / stand, this acts as “glue” to prevent the cake from moving. Place one cake layer over the frosting. Measure 3/4 to 1 cup of frosting and evenly spread that on top of the first layer. Top with the second cake layer and spread another ¾ to 1 cup of frosting on top of that layer. Use the remaining frosting around the sides and top of the cake. 

3. Decorate with sprinkles. 

Decorating Confetti Birthday Cake

Decorating Funfetti cake is so fun, pun intended! In this recipe, we decorate the cake with layers on frosting inside, and then frost the outside of the cake and finish it off with sprinkles. Here are some tips for decorating the outside of the cake with sprinkles after you’ve frosted it:

• Use a Shaker or Spoon: For even distribution of sprinkles, use a shaker or spoon to sprinkle them gently over the frosted cake. You can also use your fingers to place larger sprinkles or create specific designs carefully.
• Pat Them Gently: After applying the sprinkles, gently pat them down with clean, dry hands or a flat spatula to help them adhere to the frosting.
• Layering: Experiment with layering different types and sizes of sprinkles to create texture and visual interest. Start with larger sprinkles and then fill in the gaps with smaller ones for a fuller look.
• Add Sprinkles to the Sides: If you want to cover the sides of the cake with sprinkles, gently press them onto the frosting using your hands or a spatula. Work in small sections to ensure even coverage.
• Refrigerate if Necessary: If your frosting starts to soften too much while decorating, place the cake in the refrigerator for a few minutes to firm it up before continuing.
