From the The Silver Palate Cookbook (1982) by Julee Rosso and Sylvia Lutens.
2 sticks (1/2 pound) unsalted butter, softened
2 cups sugar
3 eggs, room temperature
3 cups sifted unbleached all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup well-shaken buttermilk
2 tightly packed tablespoons grated lemon zest
2 tablespoons fresh lemon juice
Preheat oven to 325ºF and spray a 10-inch tube pan with vegetable cooking spray.
You could also use a bundt pan, and for perfect cake release try butter-and-flour paste. Combine 1 tablespoon of butter and 1 tablespoon of flour in a small bowl. Use your fingers or a paper towel to generously coat the inside of the bundt pan with the paste, systematically working it into each crevice. Aim to evenly cover all the surfaces, including the center tube and the uppermost edges. Get rid of any excess paste.
Using electric mixer, cream butter and sugar until light and fluffy. Beat in eggs, one at a time, scraping down the sides of the bowl and blending well after each addition.
Sift together flour, baking soda and salt. On low speed, add dry ingredients gradually to the batter, alternating with buttermilk in three additions, beginning and ending with dry ingredients. Stir in lemon zest and juice.
Pour batter into pan and smooth top. Bake in middle of oven for 1 hour and five minutes, or until a cake tester inserted into the center comes out clean and cake pulls away from sides of the pan.
Make Lemon Glaze while the cake cooks.
1 pound confectioners’ sugar
1 stick unsalted butter, softened
3 tightly packed tablespoons grated lemon zest
1/2 cup fresh lemon juice
Cream sugar and butter together well. It takes a while and will look crumbly. Then add lemon juice and zest and mix thoroughly, till spreadable.
Cool cake in the pan on a wire rack for 10 minutes. Remove cake from pan, return to rack and place foil or a baking pan under rack, to catch the drips. Spread with lemon glaze at once, while the cake is still hot.
Let cake cool completely. Keeps 4-5 days wrapped in plastic wrap.
