Ingredients
Cake
- 1 1/2 cups cake flour
- 3/4 cup all purpose flour
- 1 cup granulated sugar
- 1 1/4 teaspoons baking powder
- 3/4 teaspoon baking soda
- 1/2 teaspoon salt
- 8 tablespoons unsalted butter (at room temperature)
- 2 eggs (at room temperature)
- 1/4 cup vegetable oil
- 1/2 cup milk
- 3 teaspoons vanilla extract
- 2/3 cup sour cream
Frosting
- 4 oz cream cheese (softened)
- 8 tablespoons unsalted butter (softened to room temperature)
- 4 cups powdered sugar
- 1 teaspoon vanilla extract
- 2 tablespoons heavy cream
- Gel food coloring (optional)
Instructions
- Preheat and Prepare Pans: Preheat the oven to 325°F. Grease and flour three 6-inch cake pans or spray them with cooking spray. Place parchment paper circles at the bottoms of each pan, spraying them with cooking spray as well to prevent sticking.
- Mix Dry Ingredients: Sift together cake flour, all-purpose flour, sugar, baking powder, baking soda, and salt into the bowl of a stand mixer.
- Incorporate Butter: With mixer on low speed, add the softened butter 2 tablespoons at a time. Mix until the mixture resembles coarse sand, approximately 1 minute.
- Combine Wet Ingredients: In a large liquid measuring cup, whisk together eggs, milk, vegetable oil, and vanilla extract until well blended.
- Add Wet to Dry: With the mixer on low, gradually pour the liquid ingredients into the dry mixture. Increase mixer speed to medium and mix for 1 1/2 to 2 minutes. Scrape down the sides, add sour cream, and mix on medium speed for an additional 20-30 seconds. Use a butter knife to gently break up any large air bubbles in the batter.
- Bake the Cake: Divide the batter evenly among the prepared pans. Bake in the preheated oven for 28-34 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
- Cool the Cakes: Let the cakes cool in their pans for 5-10 minutes. Then, remove them from the pans and place them on wire racks to cool completely.
- Store if Needed: If not frosting immediately, cover the cooled cakes with a double layer of plastic wrap and refrigerate until ready to frost, ideally the following day.
- Make the Frosting: Using a stand mixer fitted with the paddle attachment, cream softened butter and cream cheese together until smooth and fluffy. Gradually add powdered sugar, one cup at a time, mixing on low speed. Add vanilla extract and heavy cream, then beat on medium speed for 4 minutes. Adjust consistency as needed by adding more heavy cream if too thick, or more powdered sugar if too thin.
- Optional Coloring and Assembly: If desired, tint the frosting with gel food coloring before frosting the cake layers for a colorful presentation.
Notes
- Use cake flour for a tender crumb, but all-purpose flour is partially used to balance structure.
- Room temperature ingredients ensure better mixing and texture.
- If baking powder potency is in doubt, test before use or replace for optimal rise.
- Breaking up large air bubbles in the batter helps avoid large holes in the cake.
- Cooling cakes completely before frosting prevents melting and sliding of frosting.
- Adjust frosting consistency with heavy cream or powdered sugar for perfect spreading or piping.
