Red Velvet Cake

Steps

1. Whisk2 min
   • flour
   • baking soda
   • buttermilk
   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
   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
   • red food 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
   • vinegar
   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
   • cream cheese
   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
   • powdered sugar
   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
