1 cup butter, softened
2 cups sugar
3 cups flour
½ teaspoon baking soda
¼ teaspoon salt
½ cup milk
1 teaspoon vanilla extract
1 teaspoon cream of tartar
In a large bowl, cream together butter and sugar with an electric mixer until light and fluffy. Separate egg whites from yolks and set whites aside. Beat yolks and add to mixture. Blend until lemon-colored.
Sift together flour, baking soda, and salt. Add to above, mixing until thoroughly blended. Beat in milk and vanilla.
In a separate bowl, beat whites with cream of tartar until they hold soft peaks. Fold gently into cake batter. Pour into the prepared pan and bake for 1 hour. The edges of the cake should begin to pull away from the sides of the pan when done. Cool on a rack for 15 minutes. Loosen the sides gently with a spatula and invert onto the rack to finish cooling.
