White cake lovers treasure the image of grandma gently folding a mound of whipped egg whites into a rich, buttery batter. Unfortunately it’s whipped whites that are the cause of what a lot of people don’t like in white cake: dryness. Or, if those egg white bubbles pop en masse, density. Plus dryness. Which is really no good for anybody. Nope, when it comes to white cake the “two-stage” or “one bowl” method is really the only way to go. You’ll need:
10 ounces (scant 2 1/4 cups) cake flour
10.5 ounces (1 1/2 cups) granulated sugar
4 teaspoons baking powder
1 teaspoon salt
6 ounces (12 tablespoons) soft butter
5 egg whites
8 ounces (1 cup) milk, room temperature
2 teaspoons vanilla extract (or for fun, 1 tsp. vanilla and 1 tsp. almond)
Begin by preheating your oven to 350 degrees Fahrenheit and preparing two 9″ cake layer pans for baking. Sift the flour into the bowl of a mixer fitted with a paddle. Add in the remaining dry ingredients and stir on low for about 30 seconds to combine. Add the butter, and keep stirring until the butter is completely incorporated, about a minute. Meanwhile, combine the milk, egg whites and extract(s) in a bowl and whisk them together lightly with a fork. Add half the liquid mixture, turn the speed up to medium high and beat for about 90 seconds. Scrape the bowl, add half of what remains in the bowl, beat for about 20 seconds, scrape, add the last of the liquid, beat another 20 seconds or so.
Divide the batter among the two pans and bake on a middle rack for about 25 – 30 minutes, until the cake springs back when it’s tapped and toothpick comes out clean when it’s inserted into the center. Take the lays out of the oven, cool them on racks for about 10 minutes, then turn them out and allow them to cool completely. At that point they can be wrapped and stored at room temperature for about 2 days or frozen for about 2 months.
