Ingredients
Method
- Preheat the oven to 350°F (177°C). Grease two 9-inch round cake pans and line the bottoms with parchment paper.
- In a large bowl, whisk together cake flour, baking soda, cocoa powder, and salt. Set aside.
- Beat the butter and sugar together until creamy. Add oil, egg yolks, vanilla, and vinegar, and beat until well combined.
- On low speed, alternate adding the dry ingredients and buttermilk to the wet mixture until just combined. Mix in red food coloring to desired shade.
- In a separate bowl, whip the egg whites until soft peaks form. Gently fold into the batter.
- Divide batter evenly between pans and bake for 30–32 minutes, until a toothpick inserted in the center comes out mostly clean.
- Cool cakes completely on wire racks before frosting.
- For the frosting, beat cream cheese and butter until smooth. Add confectioners’ sugar, vanilla, and salt, and beat until light and creamy.
- Level cakes if needed. Frost between layers, then cover the top and sides with remaining frosting. Chill briefly before slicing.
Notes
Measure flour accurately to avoid a dense cake. Always frost completely cooled layers to prevent melting. Gel food coloring provides vibrant color without thinning the batter.
