Two 8- or 9-inch round layers The batter rises higher in 8-inch pans than in 9-inch pans, but the latter is fine if you don’t mind a cake with 1-inch-high layers. Please read About High-Altitude Cake Baking and About Butter Cakes. This recipe is designed for baking at 5,000 feet. If baking at 7,000 feet, preheat the oven to 350°F. Reduce the baking powder by ¼ teaspoon and the sugar creamed with the butter by 2 tablespoons (30g). Add ¼ teaspoon cream of tartar and replace the milk with buttermilk and increase by 1 ½ tablespoons (25g). Bake about 25 minutes. If baking at 10,000 feet, bake at 375°F. Use a blend of 1 ¼ cups plus 1 tablespoon sifted (130g) cake flour and 1 ¼ cups plus 1 tablespoon sifted (160g) all-purpose flour. Reduce the baking powder by ¼ teaspoon, the butter by 1 tablespoon (15g), and the sugar creamed with butter by ¼ cup (50g). Add ¼ teaspoon salt, ¼ teaspoon cream of tartar, and ½ teaspoon each vanilla and almond extract. Replace the milk with buttermilk and increase by ¼ cup (60g). Bake about 27 minutes. Have all ingredients at room temperature, about 70°F. Preheat the oven to 375°F. Thoroughly grease and flour two 8- or 9-inch round cake pans and line with rounds of parchment paper.
