- 2.5 cups cake flour spooned & leveled
- 2 teaspoons baking powder
- 0.5 teaspoon baking soda
- 1 teaspoon salt
- 0.75 cups unsalted butter softened to room temperature
- 1.75 cups granulated sugar
- 5 large egg whites at room temperature
- 0.5 cups sour cream full-fat, at room temperature
- 1 Tablespoon pure vanilla extract
- 1 cup whole milk at room temperature
Vanilla Buttercream
- 1.25 cups unsalted butter softened to room temperature

- 0.33 cups heavy cream
- 2 teaspoons pure vanilla extract or clear imitation vanilla for stark white frosting
- 0.125 teaspoon salt as needed

Instructions
Preparation
- Preheat the oven to 350°F (177°C). Grease two 9-inch round cake pans, line with parchment paper rounds, then grease the parchment paper.
- In a medium bowl, whisk the cake flour, baking powder, baking soda, and salt together. Set aside.
- In a large bowl using a mixer, beat the butter and sugar together until light and creamy, about 3 minutes. Add the egg whites and beat until combined.
- Add the sour cream and vanilla extract, and beat until combined. Add the dry ingredients and slowly pour in the milk while mixing until combined.
- Pour the batter evenly into the prepared pans and bake for 24–25 minutes or until a toothpick comes out clean.
- Cool the cakes in the pans for 1 hour, then remove from the pans and cool completely on a rack.
- For the frosting: Beat the butter until creamy, then sift in the confectioners’ sugar, add cream and vanilla, and mix until smooth.
- Assemble the cake by slicing the tops flat, layering with frosting between the cake layers, and applying a crumb coat.
- Refrigerate the cake to set the crumb coat, then finish frosting the top and sides. Decorate with sprinkles if desired.
- Slice and serve immediately or store leftovers in the refrigerator for up to 5 days.
