Cinnamon Coffee Cake Loaf

Directions

1. In a large bowl, combine the flour, 1 cup sugar, baking powder, 1-1/2 teaspoons cinnamon and salt. In another large bowl, combine the eggs, buttermilk, oil and vanilla; stir into dry ingredients just until moistened.
2. Pour half of the batter into a greased 9x5-in. loaf pan. In a small bowl, combine the remaining sugar and cinnamon; stir in butter. Sprinkle with half the cinnamon-sugar mixture; cut through batter with a knife to swirl the topping. Repeat.
3. Bake at 350° for 55-60 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing from pan to a wire rack to cool completely.
