INGREDIENTS
For the Cake
- 2 cups cake flour
- 1/2 teaspoon baking soda
- 3/4 teaspoon baking powder
- 3/4 teaspoon salt
- 1 1/2 cups granulated sugar, divided
- 1 cup sour cream, room temperature
- 2 sticks (1 cup) unsalted butter, room temperature
- 1 tablespoon canola or vegetable oil
- 1 tablespoon pure vanilla extract
- 6 large egg whites, room temperature
- 1/2 teaspoon cream of tartar
For the Seven-Minute Frosting
- 3 large egg whites
- 1 1/4 cups granulated sugar
- 5 tablespoons water
- 1/4 teaspoon cream of tartar
- 1 teaspoon pure vanilla extract
INSTRUCTIONS
For the Cake
- Preheat the oven to 350°F (175°C). Line two 8-inch cake pans with waxed or parchment paper. Grease and lightly flour the paper, but not the sides of the pans.
- In the bowl of a stand mixer, combine the cake flour, baking soda, baking powder, salt, and 1 cup of granulated sugar. Mix on low speed until well combined.
- Add half of the sour cream and the butter (one tablespoon at a time). Mix on low, scraping down the sides and bottom of the bowl as needed.
- Add the remaining sour cream, oil, and vanilla. Increase the speed to medium and mix until the batter becomes light and airy, about 2 minutes.
- In a separate bowl, beat the egg whites and cream of tartar on medium-high speed until soft peaks form. Gradually add the remaining 1/2 cup of sugar, then beat until stiff, shiny peaks form. Be careful not to over-beat.
- Gently fold the egg whites into the batter, one third at a time, until just a few streaks of egg white remain. Be gentle to maintain the airy texture.
- Divide the batter evenly between the prepared cake pans, using an offset spatula to smooth the tops. Gently tap the pans to release air bubbles.
- Bake for 30 to 35 minutes, or until the cakes are golden and a toothpick inserted into the center comes out with moist crumbs. Check at 25 minutes to avoid overbaking.
- Let the cakes cool in the pans for 15 minutes before inverting them onto a wire rack to cool completely.
For the Seven-Minute Frosting
- Fill a medium saucepan halfway with water. Bring it to a boil over medium heat, then reduce to a simmer.
- In a large heatproof bowl (that will fit over the saucepan), combine the egg whites, sugar, water, and cream of tartar. Place the bowl over the simmering water, making sure it doesn’t touch the water.
- Whisk frequently for about 5 minutes until the sugar dissolves and the mixture becomes foamy. Test by rubbing a small amount between your fingers—if it feels grainy, continue heating.
- Transfer the bowl to a stand mixer fitted with the whisk attachment. Beat on high speed for about 7 minutes, or until the frosting is glossy and tripled in volume.
- Mix in the vanilla extract (and food coloring, if desired).
- Spread the frosting generously on the cooled cake. The frosting will hold up at room temperature for up to 1 day. After day 1, it will begin to break down and seep into the cake. For best results, serve on the day it is made or the next day.
NOTES
- If the frosting disintegrates the same day, it was under-whipped.
- If the frosting has a grainy texture, the sugar wasn’t fully dissolved before whipping.
- This batter can also be used to fill 3 6-inch cake pans.
