Cozy Cinnamon Sugar Donut Bread
Tender cinnamon sugar donut bread with sweet cinnamon swirl and buttery crumb topping. Tastes like your favorite bakery donuts in loaf form, perfect for breakfast or snacking.

Creating the Perfect Donut Bread Texture
The key to achieving that signature donut texture in bread form lies in the proper balance of wet and dry ingredients. The combination of oil and milk creates a tender, moist crumb that stays fresh for days, while the eggs provide structure and richness that mimics the beloved donut experience.
The cinnamon swirl technique is crucial for distributing flavor throughout the loaf. Creating layers of batter and cinnamon mixture ensures every slice has that perfect balance of sweet bread and spiced filling, just like biting into a cinnamon sugar donut.
💡 Professional Tip
Don't overmix the batter - stir just until the flour disappears. Overmixing develops the gluten too much, resulting in a tough, dense bread instead of the tender, cake-like texture we want.
Frequently Asked Questions
Absolutely! Divide batter among 12 muffin cups, layer the cinnamon mixture, and top with crumbs. Bake at 375°F for 18-22 minutes. They're perfect for grab-and-go breakfasts.
Store covered at room temperature for up to 4 days, or wrap tightly and freeze for up to 3 months. The bread actually gets more moist after a day, making it perfect for make-ahead treats.
You can reduce the granulated sugar in the batter by up to ¼ cup, but I wouldn't reduce the cinnamon swirl sugar as it's essential for that donut flavor. The bread will be less sweet but still delicious.
You can omit the nutmeg or substitute with additional cinnamon, a pinch of allspice, or even a tiny amount of cardamom. Nutmeg adds warmth but isn't absolutely essential.
Dense bread usually results from overmixing the batter or using too much flour. Measure flour by spooning it into the cup and leveling off, and mix just until ingredients are combined.
Yes! Chopped pecans, walnuts, or even mini chocolate chips work wonderfully. Add up to ½ cup to the batter, but fold them in gently to avoid overmixing.
The bread is done when it's golden brown, springs back lightly when touched, and a toothpick inserted in the center comes out with just a few moist crumbs (not wet batter).
Substitute the milk with non-dairy milk and use vegan butter for the cinnamon swirl and crumb topping. The texture will be slightly different but still delicious.
Recipe Troubleshooting Guide
Dense or Heavy Texture
Problem: Bread turns out dense instead of light and tender
Solution: Don't overmix batter, measure flour correctly by spooning and leveling, ensure baking powder is fresh, and don't substitute oil with butter in the batter.
Cinnamon Swirl Sinks
Problem: Cinnamon mixture sinks to bottom instead of creating swirls
Solution: Make sure cinnamon mixture isn't too thin, don't add too much at once, and swirl gently without overmixing. The batter should be thick enough to support the swirl.
Crumb Topping Falls Off
Problem: Streusel topping doesn't stick to bread
Prevention: Press crumb mixture gently into batter before baking, ensure butter in topping is properly incorporated, and don't make crumbs too large or they won't adhere.
Overbaked or Dry
Problem: Bread comes out dry or overbaked
Recovery: Check oven temperature with thermometer, don't overbake (toothpick should have a few moist crumbs), and wrap bread while still slightly warm to retain moisture.
Uneven Rising
Problem: Bread rises unevenly or has a domed top
Prevention: Spread batter evenly in pan, don't overfill (should be about ¾ full), and ensure oven rack is in center position for even heat distribution.
Flavor Balance Issues
Too Sweet: Add a pinch more salt to the batter or reduce sugar slightly in next batch
Too Salty: Increase vanilla extract or add a touch more cinnamon to balance
Bland: Increase cinnamon in both batter and swirl, add more vanilla, or include a pinch of nutmeg for warmth

Selecting Quality Ingredients for Maximum Flavor
The quality of your cinnamon makes a significant difference in this recipe since it's the star flavor. Ceylon cinnamon provides a sweeter, more delicate flavor, while Cassia cinnamon offers the bold, spicy taste most people associate with bakery donuts. Fresh spices always provide better flavor than old ones.
Using whole milk rather than low-fat versions creates the richest, most tender crumb that closely mimics the texture of actual donuts. The fat content in whole milk contributes to both flavor and the moist texture that makes this bread so satisfying and long-lasting.
Essential Ingredient Notes
- Cinnamon Quality: Use fresh, high-quality ground cinnamon for the best flavor. If your cinnamon is over a year old or lacks fragrance, replace it. Ceylon cinnamon is milder, while Cassia is more intense.
- Flour Measurement: Measure flour by spooning it into the measuring cup and leveling off with a knife. Don't scoop directly from the bag as this can pack too much flour and make the bread dense.
- Oil vs Butter: Vegetable oil creates a more tender, moist bread than butter in the batter. Save the butter for the cinnamon swirl and crumb topping where its flavor really shines.

Mastering the Layering and Baking Process
The layering technique is what transforms ordinary quick bread into something special. Creating distinct layers of batter and cinnamon mixture, then gently swirling, ensures each slice has beautiful marbled patterns and consistent flavor distribution throughout the loaf.
Proper baking temperature and timing are crucial for achieving the perfect texture. The moderate temperature allows the bread to bake evenly without the outside browning too quickly, while the crumb topping develops a golden, buttery crust that adds textural contrast to the tender interior.
Perfect Swirling Technique
Use a knife to create figure-8 patterns through the layers, going just deep enough to create swirls without overmixing. Three or four swirls are usually perfect for beautiful marbled slices.

Serving Suggestions
Serve warm or at room temperature with coffee or tea. It's perfect for breakfast, brunch, or an afternoon snack. Try toasting slices lightly and serving with butter for an extra special treat.
Customization Ideas
Add orange zest to the batter for citrus notes, substitute maple syrup for some of the sugar, or fold in chopped apples for a fall twist. You can also make it in a bundt pan for special occasions.
