Red Velvet Cake

Method

1. whisk2 min
   flour + cocoa + baking soda + salt — two tablespoons of cocoa is deliberate: red velvet is not chocolate cake, and doubling the cocoa buries both the color and the buttermilk tang that defines the crumb
2. mix4 min
   medium-high, butter and sugar first, then oil
   butter + sugar creamed, then the oil streamed in — the split fat is the signature texture: butter carries flavor and creams air, oil keeps the crumb velvet-soft days later where all-butter cakes stale
3. mix3 min
   eggs one at a time, then vanilla + coloring
   + eggs singly, then vanilla and the coloring beaten in now, into the fat — pigment disperses evenly through fat; added to the finished batter it streaks, and streaky red velvet reads as an accident
4. fold3 min
   alternating with buttermilk, vinegar last
   dry and buttermilk alternating, ending on flour, the vinegar stirred in at the last — vinegar meets soda and starts lifting immediately; the batter goes to the oven now, not after a phone call
5. bake32 min
   350°F, two 8-inch pans, tester clean
   until the centers spring back — the red dulls slightly as it bakes, which is normal; chasing brightness with more bottle makes the crumb bitter
6. rest40 min
   10 in the pan, then fully cool
   completely before frosting — the same law as every layer cake, enforced harder here because the frosting is cream cheese and softens at a suggestion of warmth
7. whisk5 min
   frosting: smooth before sugar, low after
   cream cheese + butter until seamless, then powdered sugar in stages on low — beaten hard after the sugar it loosens and weeps; this frosting wants patience, not power
8. top6 min
   frosting between and over the layers, sides naked or dressed to taste — chill 30 minutes before slicing for clean red-and-white strata, the photograph this cake exists to produce
