Preheat oven to 350 degrees. Generously grease bottom of 9- x 5- x 3-inch loaf pan. Stir all ingredients in pan with fork until moistened. Beat vigorously for 1 minute. Bake until wooden toothpick inserted in center comes out clean, about 55 to 65 minutes. Cool 5 minutes. Run knife or metal spatula around side of loaf to loosen. Remove from pan.
