6tbspunsalted butter at room temp
2 large egg whites
1tsppure vanilla extract
⅓cupwhole milk at room temperature
For the Frosting
1 ½cup unsalted buttersoftened
¾cupwhole or 2% milk
Preheat the oven to 350 degrees F. Line 3, 6-inch circle pans with parchment paper. Grease and flour the pans and parchment. Set the pans aside while making the batter.
In a small bowl, sift the cake flour, baking powder, baking soda and salt. In the bowl of a mixer fitted with a paddle attachment, cream the butter and sugar until light and fluffy (about 5 minutes).
Add the eggs one at a time, mixing until just combined. Add sour cream and the vanilla extract, and mix until just combined.
Add the flour mixture and milk in three additions, starting and ending with the flour mixture.
Using a rubber spatula, fold the rainbow sprinkles into the batter. Divide the batter evenly between the pans and bake for 25 to 30 minutes or until a toothpick inserted in the center of the cake has a few crumbs stuck to it. Do not allow the cake to brown.
Allow the cakes to cool in the pans for about 15 minutes. Then turn them out of the pans and allow them to cool completely on a cooling rack.
For the Frosting
In the bowl of a stand mixer fitted with a paddle attachment, cream the butter until light and fluffy.
With the mixer on low, add the confectioner's sugar. Mix until light and fluffy. Add the salt and vanilla. Mix until combined. Add the milk or cream, beat until light and fluffy.
To Assemble the Cake
Trim the tops of the cake so they are flat. Fill each cake layer with frosting.
Refrigerate the cake for about 15 minutes to allow the frosting between the layers to chill.
Using an off set spatula, spread a very thin layer of frosting all over the cake top and sides of the cake. Place the cake in the refrigerator for about 15 minutes to chill.
Place a final, thicker layer of frosting on the cake. Spread until it is smooth. While the frosting is still tacky, press rainbow sprinkles on to the bottom edge of the cake.
Spread a layer of rainbow sprinkles on top of the cake.Using a pastry bag fitted with a star attachment (or any attachment of your choosing), decorate the sides and edges of the cake.
