This is a brown sugar loaf with a cinnamon sugar crust baked onto the top, made with oil rather than butter so it stays soft for days. There is no yeast, no kneading, and no rising time.
The crumb in the photo is the goal: dense enough to slice cleanly, moist enough that it does not need butter, and evenly amber from the brown sugar rather than pale like a plain vanilla loaf.
It takes ten minutes to mix and one hour in the oven, and it is genuinely better on day two.
Why You Will Love This Recipe
One bowl, one whisk. Dry into wet, folded once, into the pan.
Oil keeps it soft for days. Butter loaves firm up overnight in the refrigerator. Oil-based ones do not.
The crust is the best part. Cinnamon sugar sprinkled on before baking sets into a thin crackly layer over the top.
No yeast and no waiting. Quick bread means chemical leavening. Mix and bake.
It freezes perfectly in slices. Wrap individually and take one out at a time.

Ingredients
For the Loaf
• 2 cups (250 g) all-purpose flour, spooned and leveled
• 1 teaspoon baking soda
• 1/2 teaspoon baking powder
• 1 1/2 teaspoons ground cinnamon
• 1/2 teaspoon kosher salt
• 1 cup (200 g) packed light brown sugar
• 1/4 cup (50 g) granulated sugar
• 2 large eggs, room temperature
• 1/2 cup (120 ml) neutral oil such as canola or vegetable
• 1 cup (240 ml) buttermilk, room temperature
• 2 teaspoons vanilla extract
For the Cinnamon Sugar Top
• 3 tablespoons granulated sugar
• 1 teaspoon ground cinnamon
Choosing the Right Sugar and Fat
Light brown sugar gives the colour and the moisture. Its molasses content holds water in the crumb, which is why this loaf stays soft while a white-sugar version dries out.
Dark brown sugar works and produces a deeper, almost caramel flavour with a darker crumb.
Neutral oil beats butter here. Butter tastes better but sets solid when cool, which makes the loaf firm within a day. Oil stays liquid at room temperature and keeps the crumb tender.
If you want butter flavour, use half oil and half melted butter. You get some of both qualities.
Buttermilk does two things. Its acidity reacts with the baking soda for lift, and it tenderizes the crumb. If you do not have it, add 1 tablespoon of lemon juice or vinegar to a cup of milk and let it stand 5 minutes.
Why the Sugar Goes On Before Baking
Cinnamon sugar sprinkled on the batter before it goes in the oven behaves completely differently from cinnamon sugar added afterwards.
It melts and recrystallizes. The heat dissolves the sugar into the surface moisture, then it sets as the loaf cools into a thin crackly sheet rather than a loose powder.
Added after baking, it just sits there. It falls off when you slice, sticks to your fingers, and never forms a crust.
Do not stir it in. Cinnamon sugar folded into the batter disappears entirely and gives you a slightly sweeter loaf with no textural interest.
Use the full three tablespoons. It looks like too much on top of raw batter and is exactly right once baked.
How to Make Cinnamon Sugar Quick Bread
Step 1: Prepare the pan
Preheat the oven to 350°F (175°C). Grease a 9×5 inch loaf pan and line it with a parchment sling, leaving the ends hanging over the long sides.
The sling is what lets you lift the loaf out without inverting it and cracking the sugar crust.
Step 2: Whisk the dry ingredients
In a bowl, whisk the flour, baking soda, baking powder, cinnamon, and salt together for a full 20 seconds.
Baking soda that is not evenly distributed leaves bitter patches and uneven rise.
Step 3: Mix the wet ingredients
In a large bowl, whisk the brown sugar, granulated sugar, eggs, and oil until smooth and slightly glossy, about 1 minute.
Then whisk in the buttermilk and vanilla.
Room temperature ingredients matter. Cold buttermilk and cold eggs cause the oil to seize into small lumps that never fully incorporate.
Step 4: Combine
Add the dry ingredients to the wet and fold with a rubber spatula until just combined, about 12 to 15 strokes. Stop as soon as no dry flour is visible.
The batter should look slightly lumpy. Overmixing develops gluten and produces a tough, rubbery loaf with tunnels through it.
Step 5: Fill the pan
Pour the batter into the prepared pan and smooth the top gently.
Step 6: Add the cinnamon sugar
Stir the 3 tablespoons of granulated sugar and 1 teaspoon of cinnamon together and sprinkle evenly across the entire surface.
Do not swirl it in. It belongs on top.
Step 7: Bake
Bake for 55 to 65 minutes, until a skewer inserted into the centre comes out with a few moist crumbs but no wet batter.
If the top is browning too fast at around 40 minutes, tent loosely with foil.
Step 8: Cool in the pan
Let the loaf sit in the pan for 15 minutes. This lets the structure set before it has to support its own weight.
Step 9: Lift out and cool fully
Use the parchment sling to lift the loaf onto a wire rack and cool for at least another 15 minutes before slicing.
Slicing hot quick bread compresses the crumb and gives you a gummy, dense texture. It is worth the wait.
Tips for the Best Quick Bread
Spoon and level your flour. Scooping the cup directly into the bag packs in up to 25 percent extra flour, which is the leading cause of dry, heavy loaves.
Use room temperature buttermilk and eggs. Ten minutes on the counter, or a few seconds of buttermilk in the microwave, is enough.
Do not overmix. Twelve to fifteen folds. Lumps are correct.
Check early. Ovens vary considerably, and this loaf goes from moist to dry in about five minutes. Start testing at 50 minutes.
Let it cool before slicing. The crumb is still setting as it cools.
Common Mistakes to Avoid
Overmixing the batter. Produces a tough loaf with long tunnels and a domed, cracked top that splits unevenly.
Using cold ingredients. Cold buttermilk seizes the oil and gives an uneven crumb.
Opening the oven in the first 30 minutes. The loaf is still rising and the temperature drop can make it sink in the centre.
Baking in a glass pan without adjusting. Glass conducts heat differently. Reduce the oven to 325°F and add about 10 minutes.
Slicing it warm. Gummy texture and a crumbling sugar crust.
Easy Variations
• Cinnamon swirl. Reserve half the cinnamon sugar, layer half the batter, sprinkle it, then add the rest of the batter.
• Apple cinnamon. Fold in 1 cup of finely diced apple tossed in a tablespoon of flour.
• Brown butter. Replace the oil with 1/2 cup of browned and cooled butter for a nuttier flavour and a firmer crumb.
• Cream cheese glaze. Whisk 4 ounces of cream cheese with 1/2 cup powdered sugar and 2 tablespoons milk and drizzle over the cooled loaf.
• Muffins. Divide into 12 muffin cups and bake at 375°F for 18 to 20 minutes.
• Nutty. Fold in 3/4 cup of chopped toasted pecans or walnuts.
What to Serve With It
Coffee or black tea is the natural pairing, and this loaf is sweet enough to stand alone with either.
For breakfast, toast a slice in a dry pan and top with butter or cream cheese. Toasting recrisps the sugar crust.
For dessert, warm a slice slightly and serve with vanilla ice cream or a spoonful of whipped cream.
It also works alongside a fruit salad or yogurt for a lighter plate.
Make-Ahead and Storage
Make-ahead: This loaf is genuinely better on day two, once the moisture has redistributed through the crumb. Bake it the day before you need it.
Room temperature: Wrap tightly and store for up to 4 days. Do not refrigerate, which dries quick breads out faster than anything else.
Freezer: Freeze the whole cooled loaf wrapped in plastic and foil, or freeze individual slices, for up to 3 months.
To reheat: Thaw slices at room temperature, or warm at 300°F for 8 minutes. A slice goes from frozen to good in a toaster on a low setting.
Frequently Asked Questions
Why did my loaf sink in the middle?
Usually underbaking, or the oven door was opened while it was still rising. Test with a skewer rather than the clock.
Can I use butter instead of oil?
Yes, use 1/2 cup melted and cooled. The flavour is richer but the loaf firms up faster over a day or two.
Can I make it without buttermilk?
Yes. Add 1 tablespoon of lemon juice or white vinegar to a cup of milk and let it stand for 5 minutes.
Why is my crumb dense and gummy?
Overmixing, too much flour, or slicing while warm. All three are common and all three are avoidable.
Can I halve the sugar?
You can reduce the brown sugar to 3/4 cup, but going lower affects the moisture as well as the sweetness, since brown sugar is holding water in the crumb.
Can I double the recipe?
Yes, in two separate pans. One large pan will not bake through evenly in the centre.

Final Thoughts
Cinnamon sugar quick bread is a ten-minute batter that rewards two small disciplines: stop mixing early, and let it cool before you cut it.
Use brown sugar and oil rather than white sugar and butter, put the cinnamon sugar on top instead of stirring it in, and you get a loaf that is still soft on day three.
