Ingredients
For the Cake
- 2 1/2 cups all-purpose flour
- 1 1/2 cups granulated sugar
- 1 cup buttermilk, room temperature
- 1 cup vegetable oil
- 2 large eggs, room temperature
- 2 tablespoons unsweetened cocoa powder
- 2 tablespoons red food coloring (liquid gel)
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1 teaspoon white vinegar
- 1/2 teaspoon salt
For the Cream Cheese Frosting
- 16 oz cream cheese, softened
- 1/2 cup unsalted butter, softened
- 4 cups powdered sugar, sifted
- 2 teaspoons vanilla extract
- 1/8 teaspoon salt
Directions
- Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, then line the bottoms with parchment paper.
- In a large bowl, sift together the flour, cocoa powder, and salt. In another bowl, whisk the buttermilk, oil, eggs, vanilla, and red food coloring until smooth and evenly colored.
- Gradually beat the sugar into the wet mixture, then add the dry ingredients in three additions, mixing on low just until combined after each. Do not overmix.
- In a small cup, stir the baking soda and vinegar together — it will fizz — and immediately fold into the batter. The reaction lifts the cake for a tender crumb.
- Divide the batter evenly between the prepared pans and bake for 28 to 32 minutes, until a toothpick inserted in the center comes out with just a few moist crumbs.
- Cool the cakes in the pans for 10 minutes, then turn out onto wire racks and cool completely before frosting, about 1 hour.
- Meanwhile, beat the softened cream cheese and butter with an electric mixer until light and fluffy, 2 to 3 minutes. Add the vanilla and salt.
- Slowly add the sifted powdered sugar, beating on low, then increase speed and whip until the frosting is smooth, spreadable, and holds soft peaks.
- Place one cake layer on a serving plate and spread about 3/4 cup frosting evenly over the top. Stack the second layer and frost the top and sides with the remaining frosting, creating gentle swirls.
- Refrigerate the frosted cake for at least 30 minutes to set the frosting before slicing with a warm, dry knife for clean cuts.
Cook’s Notes
- Use gel food coloring rather than liquid for a more vibrant red without thinning the batter.
- Buttermilk is essential — do not substitute with regular milk, as the acidity activates the baking soda for proper rise and flavor.
- For the cleanest slices, wipe the knife with a warm, damp cloth between each cut.
- The cake layers can be baked a day ahead, wrapped in plastic, and stored at room temperature; frost the next day.
- Bring cream cheese and butter fully to room temperature before beating to avoid lumps in the frosting.
