- 1/2 teaspoon baking soda
- 1 teaspoon salt
- 16 tablespoons unsalted butter, room temperature
- 1½ cups granulated sugar
- 3/4 cup full fat sour cream, room temperature
- 2 tablespoons vegetable oil
- 1 tablespoon vanilla extract
- 2 large eggs, room temperature
- 2 large egg yolks, room temperature
- 1 cup 2% or whole milk, room temperature
FROSTING
- 1½ cups (3 sticks) unsalted butter, room temperature
- 24 oz./6 cups / 680g powdered sugar
- 3/4 cup/64g unsweetened cocoa powder
- 1/4 teaspoon salt, plus a pinch
- 7-8 tablespoons heavy cream
- 1 tablespoon vanilla extract
Instructions
CAKE
- Prep: Preheat the oven to 350°F. Line three 8-inch round cake pans with parchment paper, or I love these round silicone nonstick baking mats. Lightly grease the pans with nonstick cooking spray. (You may also use two 9-inch cake pans.)
- Dry Ingredients: Whisk the cake flour (measure correctly! See Notes), baking powder, baking soda, and salt together in a large mixing bowl. Set aside.
- Cream Butter and Sugar: Using a stand mixer fitted with the paddle attachment (or a handheld mixer), beat the butter and sugar on medium-high speed for 3-5 minutes (no less!), until very creamy and fluffy, occasionally scraping down the bowl.
- Add Wet Ingredients: Scrape down the bowl. Add the sour cream, vegetable oil, and vanilla extract, and beat on medium-high until combined, about 30 seconds. Mix in the eggs and the egg yolks, one at a time, blending each fully into the batter before adding the next to prevent an “eggy” taste.
- Alternate Ingredients: With the mixer on low, add the flour mixture in three additions, alternating with the milk (begin and end with dry ingredients). Stop mixing when a few steaks of flour remain, then stir the rest by hand. There should be some small lumps—do not overmix.
- Bake: Divide batter among the prepared cake pans (I use a kitchen scale). Bake at 350°F for 18-24 minutes for 8-inch pans and 25-31 minutes for 9-inch pans, or until a toothpick inserted into the center comes out with a few moist crumbs.
- Cool: Cool the cakes in the pans for 10 minutes, then invert onto wire racks to cool completely before frosting.
Chocolate Frosting
- Sift: Sift the powdered sugar, cocoa powder, and salt into a very large mixing bowl, then whisk to combine.
- Cream Butter: In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on high until smooth and fluffy, about 60 seconds.
- Combine: With the mixer on low, gradually add the sugar/cocoa mixture to the butter until mostly incorporated, then slowly add the cream and vanilla. Scrape down the sides of the bowl.
- Make it Fluffy: Increase the speed to medium-high and beat for a full 2 minutes-no less! If the frosting is too thin, add 1-2 more Tablespoons of powdered sugar. If it’s too thick, add 1- 2 more Tablespoons of cream. Taste the frosting and add a pinch more salt if it’s too sweet.
ASSEMBLE AND FROST
- Level Cakes: The cakes must be completely cool before continuing. Using a serrated knife, level the top of each cake.
- Frost: Spread the frosting evenly over the top and sides of the cake, and decorate/pipe the top as desired.
- Serve: Time permitting, refrigerate for 30 minutes before slicing for prettier, cleaner slices, then let it come to room temperature for serving. Enjoy!
Notes
- Measure flour correctly: It’s best to weigh it on a kitchen scale to avoid dense, dry cake. If you don’t have one, then fluff the flour in the container with a spoon to loosen it, then gently spoon it into the measuring cup without packing it down, then level it.
- Use room-temperature ingredients: Eggs, butter, sour cream, and milk must be at room temperature so everything blends smoothly and easily, resulting in a uniform, tender crumb.
- The butter should not be greasy or melty. It should only give slightly when pressed with your finger, AKA 67°F. (Never microwave!)
- The milk and sour cream can be microwaved for 20ish seconds to bring them to room temperature.
- Place eggs in a bowl of warm (not hot) water for 10 minutes to quickly bring them to room temperature.
