Easy Cinnamon Roll Bread

2 cups all-purpose flour 
1 tablespoon baking powder 
1/2 teaspoon salt 
1/2 cup sugar 
1 egg, room temperature
1 cup milk 
2 teaspoons vanilla extract 
1/3 cup plain greek yogurt, or sour cream
1/3 cup sugar 
2 teaspoons cinnamon 
2 tablespoons butter, melted and cooled slightly (can use water instead) 
1/2 cup powdered sugar
2 – 3 teaspoons cream or milk (as needed for consistency)
How to make it
Preheat oven to 350 F. Butter or spray a glass loaf pan. 
In a small bowl, whisk together the flour, baking powder, salt, and sugar. Set aside.
In a large bowl, whisk together the egg, milk, vanilla, and yogurt or sour cream. Add the flour mixture to the egg mixture, stirring with a spoon just until combined. Pour into the prepared loaf pan. 
In a small bowl, stir the Swirl ingredients together. Drop by teaspoonfuls onto the top of the bread; then use a knife to swirl it a couple of times into the batter. (Don’t overmix it).
Bake for 45-50 minutes or until the center tests done with a toothpick. 
Remove from the oven and cool for 15 minutes in the pan on a wire rack. Remove bread from the pan and cool completely on the rack. 
Make the Glaze by whisking the ingredients together in a small bowl until smooth, adding a dab of milk at a time until a good drizzling consistency is reached. When the bread is completely cool, drizzle the glaze over the top.
