Easy Cinnamon Roll Bread

 Ingredients

Bread Base

2 cups all-purpose flour

1 cup granulated sugar

1 teaspoon baking powder

½ teaspoon baking soda

½ teaspoon salt

1 large egg

1 cup buttermilk

¼ cup vegetable oil or melted butter

1 teaspoon pure vanilla extract

Cinnamon Swirl Filling

½ cup packed light brown sugar

1½ tablespoons ground cinnamon

2 tablespoons unsalted butter melted

Vanilla Glaze

¾ cup powdered sugar

1 to 2 tablespoons milk

½ teaspoon pure vanilla extract

Instructions

Preheat and prepare: Preheat the oven to 350°F 175°C. Grease a 9×5-inch loaf pan or line it with parchment paper, leaving a slight overhang on the sides for easy lifting.

Prepare the batter: In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt until evenly blended. In another bowl, whisk the egg, buttermilk, oil or melted butter, and vanilla until smooth. Add the wet mixture to the dry ingredients and stir gently with a spatula just until combined. Avoid overmixing.

Prepare the swirl: In a small bowl, combine the brown sugar and cinnamon. Set aside.

Layer the loaf: Pour half of the batter into the prepared pan and spread evenly. Drizzle half of the melted butter over the batter, then sprinkle two-thirds of the cinnamon-sugar mixture evenly on top.

Add the second layer: Spoon the remaining batter over the filling and gently spread to fully cover. Drizzle the remaining melted butter on top, then sprinkle with the rest of the cinnamon-sugar mixture. Using a knife or skewer, lightly swirl the surface in 3 to 4 gentle figure-eight motions to create a marbled effect without blending completely.

Bake: Place the pan in the center of the oven and bake for 45 to 55 minutes, until a toothpick inserted in the center comes out clean or with a few moist crumbs. If the top browns too quickly, loosely cover with aluminum foil during the final 10 to 15 minutes.

Cool slightly: Let the bread rest in the pan for 15 minutes, then lift it out using the parchment and transfer to a wire rack.

Glaze and serve: While the loaf is warm but not hot, whisk together the powdered sugar, 1 tablespoon of milk, and vanilla. Add additional milk gradually until a thick yet pourable consistency is reached. Drizzle evenly over the loaf and allow the glaze to set for 10 minutes before slicing.
