Ingredients

For the bread
2 cups all purpose flour
1 cup granulated sugar
4 teaspoons baking powder
1/2 teaspoon salt
1 cup milk I used whole milk
1 egg
1/4 cup oil I used canola oil
For the cinnamon sugar swirl
1/2 cup sugar
1 tablespoon cinnamon
For the vanilla glaze
1/2 cup powdered sugar
1/2 teaspoon vanilla
1 tablespoon milk

Instructions

Preheat oven to 350° F. Grease a glass 9 x 5 inch loaf pan. Whisk together the flour, sugar, baking powder and salt in a large bowl. Combine the milk, eggs and oil. Stir into the dry ingredients just until combined. Don't over stir.
To make the cinnamon sugar, whisk the cinnamon and sugar together in a small bowl. Pour only half of the batter into the loaf pan. Sprinkle with half the cinnamon sugar mixture. Top with the other half of the batter and then the remainder of the cinnamon sugar mixture.
Gently run a knife through the batter a few times to create the cinnamon swirl. TAKE CARE not to swirl the batter too much or you'll mix in all the cinnamon sugar mixture and you won't have a swirl inside the finished bread.
Bake for 55-60 minutes. Test for doneness with a knife or toothpick to make sure the bread has cooked through before removing it from the oven. Cool 10 minutes in the pan and then remove from the pan to cool on a wire rack.
Allow the bread to cool completely and then stir together the powdered sugar, vanilla, and milk to make a glaze and drizzle over the bread.
Notes
Do NOT mess with the bread right after it comes out of the oven! Test for doneness and don't even consider slicing into it warm. If you do try to slice it warm, the center will sink and it will likely fall apart!
