Cinnamon Sugar Donut Bread is a soft, moist loaf that captures all the cozy flavor of an old-fashioned cinnamon sugar donut—baked instead of fried. With a fluffy interior and a crisp, buttery cinnamon sugar topping, it’s perfect for breakfast or an afternoon snack.

Ingredients

  • 1 1/2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 cup granulated sugar
  • 1/4 cup brown sugar (optional)
  • 2 large eggs
  • 1/2 cup milk or buttermilk
  • 1/2 cup sour cream or plain yogurt
  • 1/3 cup unsalted butter, melted
  • 1 teaspoon vanilla extract

For the cinnamon sugar coating:

  • 2 tablespoons unsalted butter, melted
  • 1/4 cup granulated sugar
  • 1 teaspoon ground cinnamon

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan.
  2. In a bowl, whisk together flour, baking powder, salt, and cinnamon.
  3. In a separate bowl, mix eggs, granulated sugar, brown sugar (if using), milk, sour cream, melted butter, and vanilla extract until smooth.
  4. Combine the wet and dry ingredients, stirring just until combined. Do not overmix.
  5. Pour batter into the prepared loaf pan and smooth the top.
  6. Bake for 45–55 minutes, or until a toothpick inserted in the center comes out clean.
  7. While the bread is still warm, brush the top with melted butter and sprinkle generously with cinnamon sugar mixture.
  8. Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

Notes

  • Add a swirl of cinnamon sugar inside the batter for extra flavor.
  • Substitute half the butter with softened cream cheese for a richer loaf.
  • Fold in chopped apples or nuts for seasonal variation.
  • Use oil instead of butter in the batter if preferred, but butter adds more flavor.
  • Check for doneness at 45 minutes to prevent overbaking.
