3 cups all-purpose flour
1 tablespoon baking powder
1 teaspoon salt
1 teaspoon ground cinnamon
1 cup granulated sugar
½ cup unsalted butter, softened
2 large eggs
1 cup milk
1 teaspoon vanilla extract
½ cup granulated sugar
1 tablespoon ground cinnamon
Preheat your oven to 350°F (175°C).
Grease a 9×5-inch loaf pan with butter or cooking spray.
In a large bowl, whisk together:
flour
baking powder
salt
cinnamon
Set aside.
In another bowl, beat the softened butter and 1 cup granulated sugar together until light and fluffy.
Add eggs one at a time, mixing well after each addition.
Stir in milk and vanilla extract until fully combined.
Gradually add the dry ingredients into the wet mixture.
Mix just until combined — avoid overmixing to keep the bread soft.
Pour half of the batter into the prepared loaf pan.
In a small bowl, mix the topping sugar and cinnamon.
Sprinkle half of the cinnamon sugar mixture over the batter.
Add the remaining batter on top.
Finish with the remaining cinnamon sugar mixture.
Use a knife to gently swirl the batter to create a marbled effect.
Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Do not overmix the batter — this keeps the bread tender.
Use room-temperature ingredients for smoother mixing.
Cover loosely with foil during baking if the top browns too quickly.
For extra donut flavor, brush warm bread with melted butter and sprinkle additional cinnamon sugar on top.
This bread tastes even better the next day as flavors develop.
