If you’ve ever walked into a bakery early in the morning and smelled the warm, sugary aroma of fresh cake donuts, this recipe is designed to bring that exact experience straight into your home kitchen.
Cinnamon Donut Bread captures everything there is to love about classic cinnamon-sugar donuts—the soft, tender crumb, the subtle hint of warm spice, and that iconic, crunchy sugar shell—without any of the hassle, mess, or splattering oil that comes with deep frying. It’s an easy, one-bowl quick bread that comes together in minutes, making it an absolute favorite for weekend breakfasts, holiday brunches, or an afternoon coffee break.
The Secret Behind That “Authentic Donut” Texture & Flavor
Creating a quick bread that actually tastes like a donut comes down to two essential baker’s techniques:
- The Double Sugar Coating: Instead of just dusting the top of the loaf after baking, you coat the inside of the buttered pan with cinnamon sugar before adding the batter. As the bread bakes, the sugar caramelizes against the metal pan, creating a crispy, golden outer crust all the way around the loaf. Once it comes out of the oven, brushing the warm top with melted butter and adding another layer of cinnamon sugar seals the deal.
- The “Secret” Spice Blend: While cinnamon is the star of the show, old-fashioned bakery cake donuts get their signature flavor profile from a tiny touch of ground nutmeg. Adding just a quarter-teaspoon of nutmeg to the batter transforms a standard cinnamon cake into an undeniable donut copycat.

Ingredients List
For the Cinnamon-Sugar Pan Coating:
- 1 tablespoon unsalted butter, melted (for greasing the loaf pan)
- ¼ cup (50 g) granulated white sugar
- 1 ½ teaspoons ground cinnamon
For the Soft Donut Batter:
- 2 cups (240 g) all-purpose flour, spooned and leveled
- ¾ cup (150 g) granulated white sugar
- 1 tablespoon baking powder
- ½ teaspoon fine sea salt
- ½ teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- 1 large egg, room temperature
- 1 cup (240 ml) whole milk (or buttermilk, for extra tang)
- ⅓ cup (80 ml) vegetable oil, canola oil, or melted unsalted butter
- 1 teaspoon pure vanilla extract
For the Melted Butter Donut Topping:
- 3 tablespoons unsalted butter, melted
- 3 tablespoons granulated white sugar
- 1 teaspoon ground cinnamon
Step-by-Step Instructions
Step 1: Prepare and Coat the Pan
Preheat your oven to 350°F (175°C) and position the oven rack in the center.
In a small bowl, whisk together the ¼ cup sugar and 1 ½ teaspoons cinnamon designated for the pan coating.
Using a pastry brush, coat the entire inside of a standard 9×5-inch metal loaf pan with 1 tablespoon of melted butter. Dump the cinnamon-sugar mixture into the pan. Tilt and tap the pan around so the sugar sticks to the bottom and all four inner walls, creating a complete coating. Shake out any excess loose sugar and set it aside to use for the top later.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine the 2 cups all-purpose flour, ¾ cup sugar, 1 tablespoon baking powder, ½ teaspoon salt, ½ teaspoon cinnamon, and ¼ teaspoon nutmeg. Whisk thoroughly to distribute the baking powder and spices evenly through the flour.
Step 3: Whisk the Wet Ingredients
In a separate medium bowl or liquid measuring cup, whisk together the 1 egg, 1 cup whole milk, ⅓ cup oil (or melted butter), and 1 teaspoon vanilla extract until smooth and fully emulsified.
Step 4: Combine to Form the Batter
Pour the wet liquid mixture directly into the dry flour mixture. Using a rubber spatula, fold the ingredients together justuntil the dry streaks of flour disappear and a smooth, thick batter forms.
Baker’s Note: Take care not to overmix the batter at this stage. Overmixing activates the gluten in the flour, which will make the finished bread dense and rubbery rather than tender and cake-like.
Step 5: Bake Low and Slow
Gently spoon the batter into your prepared, sugar-coated loaf pan. Smooth the top surface lightly with your spatula.
Place in the preheated oven and bake at 350°F (175°C) for 45 to 55 minutes. The bread is done when the top is golden brown and a wooden skewer or toothpick inserted into the thickest center section comes out clean or with a few moist crumbs attached.
Step 6: The Donut Finish & Cooling
Allow the cooked loaf to rest inside the pan on a wire rack for 10 minutes.
Carefully run a thin knife around the short edges of the loaf pan, then gently invert the bread onto the wire cooling rack so it stands right-side up.
While the bread is still hot, generously brush the top and upper sides with the 3 tablespoons of melted butter. Immediately sprinkle the remaining cinnamon-sugar mixture liberally over the melted butter.
Allow the loaf to cool for at least 15 to 20 minutes before slicing. This allows the hot butter and sugar to set into a crisp, crackly shell that won’t crumble away when sliced.
Baker’s Tips for Maximum Success
- Measure Flour Correctly: Scooping flour directly out of the bag with a measuring cup packs down the flour, resulting in up to 25% extra weight. This causes quick breads to dry out. Always fluff your flour with a fork, spoon it gently into your measuring cup, and sweep off the excess with a flat knife.
- Add a Cinnamon Swirl (Optional Variation): If you want an extra hit of cinnamon flavor inside the loaf, pour half the batter into the pan, sprinkle 2 tablespoons of cinnamon sugar across the middle, pour the remaining batter over top, and swirl lightly with a butter knife before baking.
- Warm Serving Suggestion: Slice the bread thick and serve it slightly warm. A light spread of softened, salted butter over a warm slice creates an unforgettable sweet-and-salty contrast!
Storage & Reheating Guidelines
- Room Temperature: Store the fully cooled loaf wrapped loosely in foil or inside an airtight container at room temperature for up to 3 days. (Tip: Avoid sealing it in plastic wrap while warm, as trapped steam will soften the crisp cinnamon sugar top).
- Freezing: Wrap individual slices tightly in plastic wrap, followed by a layer of aluminum foil. Freeze for up to 3 months. Thaw slices at room temperature for 30 minutes, or warm them in a toaster oven for 2 to 3 minutes to crisp the crust back up before eating!
