Preheat oven to 350°. Grease two 5 inch nonstick loaf pans or one 8-inch square nonstick baking pan. Combine dry ingredients in large mixer bowl and mix well. With mixer on low, add egg, buttermilk, oil and caraway seeds. Blend on medium speed for 2 minutes. Spoon into prepared pans, smoothing tops with wet spatula, if necessary. Bake small pans for 45-50 minutes, large pan for 50-55 minutes, until top is deeply browned and loaf sounds hollow when tapped.
