Ingredients You’ll Need

Let’s gather everything for this patriotic layer cake and its silky buttercream frosting.

For the Vanilla Layer Cake:

3 cups all-purpose flour
2½ teaspoons baking powder
½ teaspoon salt
1 cup unsalted butter (cold, cubed)
2 cups granulated sugar
4 large eggs
1 tablespoon pure vanilla extract
1 cup sour cream
¾ cup whole milk
Gel food coloring: super red, royal blue (recommended brands: Americolor, ChefMaster)

For the Buttercream Frosting:

2 cups unsalted butter (cold, cubed)
7 cups powdered sugar
1 tablespoon pure vanilla extract
4 tablespoons heavy whipping cream (or milk)
Pinch of salt

Pro Tip: This sour cream vanilla cake provides the perfect tender crumb while the cold butter frosting technique ensures a fluffy, stable buttercream—essential for those hot July celebrations.

How to Color and Prepare the Cake Batter

Prepare your favorite vanilla extract cake batter and divide it evenly into three bowls.
Leave one bowl white, color one with super red gel food coloring, and the last with royal blue.
Stir gently until fully blended, being careful not to overmix—this ensures your layers bake evenly and stay vibrant.
Use Americolor or ChefMaster gel food coloring for that vivid red and deep blue without thinning the batter.

This process transforms your basic batter into a stunning red, white, and blue cake, guaranteed to turn heads at your Fourth of July party dessert table.

The Secret to Perfect Buttercream Frosting

If you want that bakery-style, cloud-like frosting, here’s how:

Beat cold butter on high for 5-7 minutes until creamy and pale.
Gradually add powdered sugar, alternating with vanilla and heavy cream, beating for an additional 3-5 minutes at the end.
The result? A luscious buttercream frosting for layer cake that’s perfect for both filling and decorating.

This frosting also works wonders for piping tricolor frosting using a simple crumb coat frosting tutorial, giving your cake that festive finish.

Assembling Your 4th of July Layer Cake Like a Pro

Level the cake layers using a serrated knife or cake leveler.
Stack the royal blue cake layer first, followed by a layer of buttercream, then the white layer, frosting, and finally the red layer on top.
Apply a thin crumb coat, chill the cake for 20-30 minutes.
For an eye-catching finish, create a tricolor ombre frosting effect by piping red, white, and blue stripes using plastic wrap inside a piping bag fitted with an Ateco 848 star tip.
