- 1 cup (2 sticks) unsalted butter, softened, plus more for pan
- 3 cups all-purpose flour (spooned and leveled), plus more for pan
- 3/4 cup low-fat buttermilk
- Zest of 2 lemons, finely grated
- 1/3 cup fresh lemon juice (about 2 lemons)
- 1 1/2 teaspoons salt
- 1/2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 2 cups sugar
- 5 large eggs
- Lemon Glaze (http://www.marthastewart.com/285341/lemon-glaze)
- Preheat oven to 350 degrees, with rack in lowest position. Butter and flour two 4 1/2-by-8-inch (6-cup) loaf pans.
- In a small bowl (or liquid measuring cup), combine buttermilk with lemon zest and juice. In a medium bowl, whisk together flour, salt, baking powder, and baking soda.
- With an electric mixer, cream butter and sugar until light and fluffy. Add eggs, one at a time, beating well after each addition.
- With mixer on low, add flour mixture in three parts alternately with the buttermilk mixture in two, beginning and ending with flour; beat just until smooth (do not overmix).
- Divide batter evenly between pans; smooth tops. Bake until a toothpick inserted in centers comes out clean, 50 to 60 minutes (tent with foil if browning too quickly). Cool 15 minutes in pan. Turn out cakes onto a rack; cool completely before glazing.
- Set rack with cakes over a baking sheet lined with waxed paper. Pour glaze over cakes, letting it run down the sides; let dry, about 30 minutes.
The batter can also be baked in a 12-cup buttered and floured nonstick Bundt pan; the cooking
and cooling times are the same.
