Common Questions About This Cinnamon Loaf
Can I prepare it ahead of time?
Absolutely! This loaf actually tastes even better the next day, as the cinnamon-sugar flavors meld together. Wrap it tightly at room temperature for up to 3 days for maximum freshness.
Can I freeze it?
Yes! Once fully cooled, wrap the loaf in plastic wrap and then foil. It will last in the freezer for up to 2 months. Let it thaw at room temperature before serving.
Can I add nuts or dried fruit?
Definitely! Stir in about ½ cup of chopped walnuts, pecans, or raisins for added texture and flavor.
How should I serve it?
We love this loaf slightly warmed with a pat of butter, though it’s just as delightful at room temperature. Pair it with coffee, tea, or a cold glass of milk for a cozy snack.
Can I double the recipe?
Yes! The recipe doubles nicely. Use two loaf pans and adjust the baking time slightly—start checking for doneness around 50 minutes.
Ingredients You’ll Need
For the Loaf:
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 1 tablespoon baking powder
- ½ teaspoon salt
- 1 cup buttermilk (or 1 cup milk + 1 tablespoon vinegar, let sit 5 minutes)
- ⅓ cup vegetable oil
- 2 large eggs
- 1 teaspoon vanilla extract
For the Cinnamon-Sugar Swirl and Topping:
- ½ cup granulated sugar
- 2 teaspoons ground cinnamon
- 2 tablespoons butter, melted (for brushing the top)
Tools That Help:
- 9×5 inch loaf pan
- Mixing bowls
- Hand or stand mixer (optional)
- Pastry brush
Step-by-Step Instructions
- Preheat the oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan, or line it with parchment paper for easy removal.
- Mix the dry ingredients: In a large bowl, whisk together flour, sugar, baking powder, and salt.
- Mix the wet ingredients: In another bowl, whisk together buttermilk, oil, eggs, and vanilla extract until smooth.
- Combine wet and dry: Gradually stir the wet mixture into the dry ingredients just until combined. A few lumps are fine—overmixing can make the loaf dense.
- Prepare the cinnamon-sugar mixture: In a small bowl, combine sugar and cinnamon.
- Layer the batter: Pour half of the batter into the prepared pan, then sprinkle half of the cinnamon-sugar mixture over it. Add the remaining batter and top with the rest of the cinnamon-sugar.
- Create the swirl: Use a butter knife to gently swirl the cinnamon-sugar through the batter, creating ribbons without overmixing.
- Bake: Place in the oven and bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
- Finish with topping: While still warm, brush the top with melted butter and sprinkle with additional cinnamon-sugar for a crackly, donut-like finish.
- Cool: Allow the loaf to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
Tips for Perfect Cinnamon Donut Loaf
- Avoid overmixing for a soft, tender loaf. A few lumps are okay.
- Use room-temperature eggs and buttermilk for an evenly baked batter.
- Customize the flavor with a pinch of nutmeg or swap brown sugar for part of the sugar for a deeper caramel note.
- Allow the loaf to cool fully before slicing to preserve the swirl pattern.
- If you love extra sweetness, double the cinnamon-sugar topping.
