Classic Vanilla Butter Cake with Buttermilk Sauce — The Southern Comfort Dessert That Needs No Frosting


Ingredients You’ll Need

(Serves 8–10)

For the Vanilla Butter Cake:

  • 2 cups (250g) all-purpose flour
  • 1½ tsp baking powder
  • ½ tsp baking soda
  • ½ tsp fine sea salt
  • ½ cup (1 stick / 115g) unsalted butter, softened to room temperature
  • 1¼ cups (250g) granulated sugar
  • 2 large eggs, room temperature
  • 1 tbsp pure vanilla extract
  • 1 cup (240ml) buttermilk, room temperature

For the Buttermilk Sauce:

  • 1 cup (200g) granulated sugar
  • ½ cup (1 stick / 115g) unsalted butter
  • ½ cup (120ml) buttermilk
  • ¼ tsp baking soda
  • 1 tsp pure vanilla extract
  • Pinch of salt
💡 Pro Tips:
    • Room-temp ingredients = smoother batter, better rise
    • Real buttermilk only—not milk + vinegar substitute (texture differs)

  • Don’t skip baking soda in sauce—it creates the signature “buttery foam” texture
