To me, when it comes to celebrating birthdays, there isn’t such a thing as too many sprinkles. That’s why I love this smash cake and birthday cake combo. I stir sprinkles into the batter AND decorate with sprinkles once the cakes are frosted. I love to use large confetti sprinkles to decorate the large cake.

Ingredients
- 1 1/2 cups (3 sticks) unsalted butter, softened, plus more for greasing the pans
- 3 3/4 cups cake flour, plus more for flouring the pans
- 1 tablespoon baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon kosher salt
- 2 cups granulated sugar
- 6 large egg whites
- 1/2 cup sour cream
- 1 tablespoon vanilla extract
- 1 cup whole milk
- 3/4 cup favorite confetti sprinkles
- 2 cups (4 sticks) unsalted butter, softened
- 8 to 10 cups powdered sugar
- 3 to 4 tablespoons heavy cream
- 2 tablespoons vanilla extract
- 2 teaspoons kosher salt
- Blue food coloring, optional
- Large multicolor confetti sprinkles, optional (see Cook’s Note)
- Blue sprinkles, optional
Instructions
- For the cake: Grease and flour 2 6-inch cake pans and 3 8-inch cake pans. Preheat the oven to 350 degrees F. Stir together the flour, baking powder, baking soda and salt in a large bowl.
- Beat the butter and granulated sugar together on medium speed with an electric mixer until creamy. Beat in the egg whites until fluffy. Add the sour cream and vanilla and beat until smooth. Add the flour mixture alternately with the milk in three additions, beginning and ending with the flour mixture. Fold in the sprinkles.
- Spoon the batter into the prepared pans. Bake the 6-inch pans for until a toothpick inserted in the center comes out clean, 18 to 20 minutes. Bake the 8-inch pans until a toothpick inserted in the center comes out clean, 20 to 22 minutes. Remove the cakes to wire racks to cool in the pans 5 minutes. Turn out onto wire racks to cool completely.
- For the vanilla buttercream: Beat the butter at medium speed with an electric mixer until creamy. Add the powdered sugar, 1 cup at a time, until combined. Add the cream, vanilla and salt and beat to a spreadable consistency. Tint some of the frosting with blue food coloring, if desired.
- Build the cake: Stack the 8-inch cakes with frosting spread between the layers. Stack the 6-inch cakes on top of the 8-inch ones and spread frosting between the layers. Frost the top and side of the cake. Decorate with confetti and/or blue sprinkles, if desired.

My go to cake recipe now!
Love this ! So moist!
Writing a review to offset the rude review above demanding a different recipe. Cook both, freeze one for later. Oh my, people want others to hold their hands.
Any recommendations for how to adjust the ingredient quantities if you only want to make the smash cake and not the three layer 8″ cake?
I would like to try the cake but want recipe ingredients adjustments for the three layer birthday cake without the Smash Cake. Thank you!
Love this! Easy enough to do with a lovely outcome! Yummy and beautiful!
Love, Kardea! Great show! Fun recipes!
