Someone on another cake site introduced me to the King Arthur's White Cake and it is by far my favorite recipe! I absolutely love it and it is my "go-to" recipe for white cakes. It also does really well with substitutions (the cake calls for a cup of milk, I've substituted a cup of brewed Vanilla Chai Tea and it makes the most delicious Chai Tea Cake. I make this with the WBH House Buttercream which calls for a cup of boiling water and I sub that out for another cup of brewed Vanilla Chai Tea and it's heavenly!!! Of course, when subbing tea into the buttercream, I can only do it for cakes where I'm coloring the icing because with the tea added to the buttercream you won't get a white icing, more of a cream one). Here's the recipe:
King Arthur White Cake
8 tablespoons (1 stick, 4 oz.) butter, softened
1/2 cup (3-1/4 oz.) vegetable shortening
1 tablespoons (1/2 oz.) baking powder
1-3/4 cups (12-1/4 ounces) sugar
3/4 teaspoon salt
2 teaspoons vanilla extract
1 teaspoon almond extract
-- Cream together until light. 5 min. or more.
5 large egg whites (6 to 7 oz.)
-- Add egg whites one at a time and beat well after
each addition.
2-3/4 cups (11 oz.) cake flour
1 cup (8 oz.) milk
-- Stir in flour and milk, alternating between the
two, starting and ending with the flour. (i.e. 1/3
flour, 1/2 milk, 1/3 flour, 1/2 milk, 1/3 flour)
-- Bake at 350. 25-35 minutes or until done.
