A classic yellow cake with chocolate frosting or vanilla frosting or any kind of frosting is a favorite dessert for a reason. It's really yummy! But sometimes it can be hard to get that fluffy, delicious goodness from scratch, so you immediately go to the boxed stuff. That's all well and good, but why not try making one for yourself since you probably have all the ingredients already?
This yellow cake recipe with chocolate sour cream frosting from Smitten Kitchen is one of the best we've tried. The buttermilk gives it a smooth, rich texture, and if you don't like the idea of sour cream frosting, just use your favorite chocolate frosting to top this decadent cake off. You'll never go back to the boxed stuff again!
Yellow Cake Recipe With Chocolate Sour Cream Frosting by Smitten Kitchen
Yield: Two 9-inch round, 2-inch tall cake layers
4 cups plus 2 tablespoons (480 grams) cake flour (not self-rising)
2 teaspoons (10 grams) baking powder
1 1/2 teaspoons baking soda
1 teaspoon (5 grams) table salt
2 sticks (1 cup, 1/2 pound or 225 grams) unsalted butter, softened
2 cups (400 grams) sugar
2 teaspoons (10 ml) pure vanilla extract
4 large eggs, at room temperature
2 cups buttermilk (475 ml), well-shaken
Preheat oven to 350°F. Butter two 9-inch round cake pans and line with circles of parchment paper, then butter parchment. (Alternately, you can use a cooking spray, either with just butter or butter and flour to speed this process up.)
Sift together flour, baking powder, baking soda, and salt in a medium bowl. In a large mixing bowl, beat butter and sugar in a large bowl with an electric mixer at medium speed until pale and fluffy, then beat in vanilla. Add eggs 1 at a time, beating well and scraping down the bowl after each addition. At low speed, beat in buttermilk until just combined (mixture will look curdled). Add flour mixture in three batches, mixing until each addition is just incorporated.
Spread batter evenly in cake pan, then rap pan on counter several times to eliminate air bubbles. (I like to drop mine a few times from two inches up, making a great big noisy fuss.) Bake until golden and a wooden pick inserted in center of cake comes out clean, 35 to 40 minutes. Cool in pan on a rack 10 minutes, then run a knife around edge of pan. Invert onto rack and discard parchment, then cool completely, about 1 hour.
Chocolate Sour Cream Frosting
Cooking note: Be sure that your sour cream is at room temperature before you make the frosting.
Makes 5 cups of frosting, or enough to frost and fill a two layer 9-inch cake
15 ounces semisweet or bittersweet chocolate, chopped
1 1/4 teaspoons instant espresso (optional, but can be used to pick up the flavor of average chocolate)
2 1/4 cups sour cream, at room temperature
1/4 to 1/2 cup light corn syrup
3/4 teaspoon vanilla extract
Combine the chocolate and espresso powder, if using, in the top of a double-boiler or in a heatproof bowl over simmering water. Stir until the chocolate is melted. (Alternately, you can melt the chocolate in a microwave for 30 seconds, stirring well, and then heating in 15 second increments, stirring between each, until the chocolate is melted.) Remove from heat and let chocolate cool until tepid.
Whisk together the sour cream, 1/4 cup of the corn syrup, and vanilla extract until combined. Add the tepid chocolate slowly and stir quickly until the mixture is uniform. Taste for sweetness, and if needed, add additional corn syrup in one tablespoon increments until desired level of sweetness is achieved.
Let cool in the refrigerator until the frosting is a spreadable consistency. This should not take more than 30 minutes. Should the frosting become too thick or stiff, just leave it out until it softens again.
