Ingredients
For the Bread
- 2 cups all-purpose flour
- 1 tablespoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 2 teaspoons ground cinnamon
- ½ cup unsalted butter, melted
- ¾ cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup buttermilk (or milk with 1 tablespoon lemon juice, let sit 5 minutes)
For the Cinnamon Swirl
- ½ cup granulated sugar
- 2 teaspoons ground cinnamon
- 2 tablespoons melted butter
For the Glaze
- 1 cup powdered sugar
- 2–3 tablespoons milk
- ½ teaspoon vanilla extract
Step 1: Preheat and Prepare the Pan
Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan with butter or non-stick spray, or line it with parchment paper. Proper preparation ensures the bread releases cleanly after baking and keeps the crust soft yet slightly golden.
Step 2: Make the Cinnamon Swirl
In a small bowl, mix together granulated sugar and cinnamon. Stir in melted butter until the mixture is crumbly but spreadable. Set aside. This mixture will create the signature cinnamon-sugar pockets inside the bread.
Step 3: Mix Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, salt, and 2 teaspoons cinnamon. These dry ingredients provide the structure of the bread while infusing it with warm cinnamon flavor.
Step 4: Combine Wet Ingredients
In a large bowl, whisk melted butter with sugar until smooth. Add eggs and vanilla extract, mixing until fully incorporated. Stir in buttermilk gradually, creating a smooth, slightly thick batter. The buttermilk keeps the bread tender and moist while adding a subtle tang.
Step 5: Combine Wet and Dry Ingredients
Gently fold the dry ingredients into the wet mixture until just combined. Avoid overmixing, as this can make the bread dense. The batter should be thick but pourable.
Step 6: Layer the Cinnamon Swirl
Pour half of the batter into the prepared loaf pan. Sprinkle half of the cinnamon-sugar mixture evenly over the batter. Pour the remaining batter on top, then finish with the rest of the cinnamon-sugar mixture. Use a knife or skewer to gently swirl the cinnamon into the batter, creating a marbled effect. Be careful not to over-swirl, which can flatten the texture.
Step 7: Bake
Bake the loaf in the preheated oven for 45–55 minutes, or until a toothpick inserted in the center comes out clean. If the top browns too quickly, loosely cover with aluminum foil for the last 10 minutes. Once baked, remove from the oven and let it cool in the pan for 10 minutes before transferring to a wire rack.
Step 8: Prepare the Glaze
In a small bowl, whisk powdered sugar with milk and vanilla extract until smooth. Adjust the consistency by adding more milk if too thick or more powdered sugar if too thin. Drizzle the glaze over the slightly cooled loaf. The glaze hardens slightly, creating a sweet, donut-like crust on top.
Step 9: Serve
Slice the Cinnamon Donut Bread into thick pieces and serve warm for the best experience. The bread is soft and fluffy on the inside with pockets of sweet, spiced swirl throughout, and the glaze adds a perfect finishing touch. It pairs wonderfully with coffee, tea, or a glass of milk.
Tips and Variations
- For extra texture, sprinkle chopped nuts or mini chocolate chips along with the cinnamon swirl.
