Red Velvet Cake

Magnolia Bakery Red Velvet Cake with Creamy Vanilla Frosting

Cake
3 1/3 cups cake flour (not self-rising)
OR 2 ½ cups all purpose flour
3/8 cup + 2 tsp corn starch
¾ cup (1 ½ sticks) unsalted butter, softened
2 ¼ cups sugar
3 large eggs, at room temperature
6 tablespoons red food coloring
3 tablespoons unsweetened cocoa
1 ½ teaspoons vanilla extract
1 ½ teaspoons salt
1 ½ cups buttermilk
1 ½ teaspoons cider vinegar
1 ½ teaspoons baking soda

Preheat the oven to 350 degrees.
Grease and lightly flour three 9 x 2-inch round cake pans, then line the bottom with waxed paper.
To make the cake: In a small bowl, sift the cake flour and set aside. In a large bowl, on the medium speed of an electric mixer, cream the butter and sugar until very light and fluffy, about 5 minutes. Add the eggs, one at a time, beating well after each addition.
In a small bowl, whisk together the red food coloring, cocoa, and vanilla. Add to the batter and beat well.
In a measuring cup, stir the salt into the buttermilk. Add to the batter in three parts, alternating with the flour. With each addition, beat until the ingredients are incorporated, but do not over beat.
In a small bow, stir together the cider vinegar and baking soda. Add to the batter and mix well. Using a rubber spatula, scrape down the batter in the bowl, making sure the ingredients are well blended and the batter is smooth.
Divide the batter among the prepared pans. Bake for 30-40 minutes, or until a cake tester inserted in the center of the cake comes out clean. Let the layers cool in the pans for 1 hour. Remove from the pans and cool completely on a wire rack.
When the cake has cooled, spread the frosting between the layers, then the ice top and sides of the cake with Creamy Vanilla Frosting.

Makes one 3-layer 9-inch cake

Frosting
6 tablespoons all-purpose flour
2 cups milk
2 cups (4 sticks) unsalted butter, softened
2 cups sugar
2 teaspoons vanilla extract

In a medium-size saucepan, whisk the flour into the milk until smooth. Place over medium heat and , stirring constantly, cook until the mixture becomes very thick and begins to bubble, 10-15 minutes. Cover with waxed paper placed directly on the surface and cool to room temperature, about 30 minutes.
In a large bowl, on the medium high speed of an electric mixer, beat the butter for 3 minutes, until smooth and creamy. Gradually add the sugar, beating continuously 3 minutes, until smooth and fluffy. Add the vanilla and beat well.
Add the cooled milk mixture, and continue to beat on the medium high speed for 5 minutes, until very smooth and noticeably whiter in color. Cover and refrigerate for 15 minutes (no less and no longer – set a timer!) Use immediately.
