Method
- Preheat oven to 350°F (177°C). Grease two 9-inch cake pans with butter, line with parchment paper rounds, then grease the parchment paper. This ensures easy cake removal.
- In a large bowl, whisk together cake flour, baking soda, cocoa powder, and salt. Set aside.
- Using a stand mixer or hand mixer, beat softened butter and granulated sugar on medium-high speed until combined, about 1 minute. Scrape down bowl sides as needed.
- Add oil, egg yolks (reserve whites), vanilla extract, and vinegar to butter mixture. Beat on high speed for 2 minutes until well combined.
- With mixer on low speed, add dry ingredients in 2-3 additions, alternating with buttermilk. Begin and end with dry ingredients. Mix just until combined.
- Beat in red food coloring until desired color is achieved. Start with 1 teaspoon and add more as needed.
- In a separate clean bowl, whip the 4 egg whites on high speed until fluffy peaks form, about 3 minutes. Gently fold whipped whites into cake batter using a rubber spatula.
- Divide batter evenly between prepared cake pans. Bake for 30-32 minutes, until tops spring back when gently touched and a toothpick inserted in center comes out clean.
- Remove from oven and cool completely in pans on wire racks before removing. Cakes must be completely cool before frosting.
- For frosting: Beat cream cheese and butter together until smooth, about 2 minutes. Add powdered sugar, vanilla, and salt. Beat on low for 30 seconds, then high speed for 3 minutes until creamy.
- Using a serrated knife, level cake tops if needed. Place first layer on serving plate, spread frosting on top. Add second layer and frost entire cake. Refrigerate 30-60 minutes before slicing.
Notes
Make-Ahead Tips: Cake layers can be baked and stored covered at room temperature overnight. Frosting can be made ahead and refrigerated overnight.
Storage: Store covered cake in refrigerator for up to 5 days. Unfrosted layers freeze for 2-3 months.
Room Temperature Ingredients: All ingredients mix better at room temperature, creating a more uniform texture.
Food Coloring: Gel food coloring is more concentrated than liquid. For natural coloring, try beet powder.
Cake Flour Substitute: If unavailable, use 2 3/4 cups all-purpose flour plus 1/4 cup cornstarch, sifted together.
