This made from scratch Funfetti Cake that is light, fluffy and full of sprinkles. The buttercream frosting is the perfect addition to this DIY birthday cake.
Grease 3, 8-inch cake pans and line the bottom with parchment paper. This helps the cake to not stick in the pan and is worth the extra effort.
Beat egg whites and ½ cup sugar with a stand mixer or a hand mixer until it forms a stiff peak. Set aside.
In a large bowl cream together the butter, 1 ½ cup sugar and vanilla.
In a separate bowl combine flour, baking powder, and salt
Add flour mixture alternating with the milk to the butter mixture until a smooth batter forms.
Fold in egg whites and rainbow sprinkles.
Divide into prepared pans and smooth the top of the batter with a spatula.
Bake 25-30 minutes or until the cake springs back lightly when touched.
Cool completely before adding the frosting.
For the Frosting
Cream together butter and cream cheese until very smooth and fluffy, about 3 minutes.
Add powder sugar and mix until fully combined.
Add heavy cream vanilla and salt and beat to combine.
If it seems too stiff add more cream, a teaspoon at a time, until it creates a smooth icing.
Decorate with Sixlet candies and more rainbow sprinkles.
Notes
This cake is SO much fun! I like to use the sprinkles that are sometimes called jimmies. They are the long skinny sticks instead of balls. The sprinkles that are colored balls seem to loose their color too easily.
You can use other colors of sprinkles too if they fit your theme. We used a pretty maroon red sprinkle for this cake for my one layer of brother's wedding cake! The other layers were all white and one was a red velvet cake. It was beautiful.
Don't skip adding the parchment paper to the bottom of the cake pans, it makes a big difference when it comes to cakes that come out of the pan clean.
