Simple Step Guide
- Get Set:
- Crank the oven to three fifty. Grease a nine by five loaf pan or use parchment for easier cleanup.
- Start with Dry:
- Mix together flour, granulated sugar, baking soda, baking powder, and salt in a big bowl. Whisk well so everything blends nicely.
- Mix the Wet:
- In another bowl, whisk eggs, buttermilk, melted butter, and vanilla extract until totally smooth and creamy.
- Make the Batter:
- Pour the wet into the dry stuff. Gently fold with a spatula just until the flour is gone. Over-mixing here makes it chewy—so stop as soon as it’s all combined.
- Whip up the Swirl:
- Mix brown sugar and cinnamon in a small bowl—make sure it’s totally mixed, no clumps.
- Layer It Up:
- Add half your batter to the loaf pan. Sprinkle half of the cinnamon sugar over it. Pour the rest of the batter, then finish with more cinnamon sugar. Grab a butter knife and swirl it through—this makes the prettiest lines.
- Time to Bake:
- Bake for about fifty to sixty minutes. You’ll know it’s done when a toothpick comes out clean (a few moist crumbs are fine) and the top’s golden.
- Cool Down:
- Let the loaf cool for ten minutes in the pan. Then gently move it to a wire rack to fully cool. Waiting helps it firm up so it doesn’t fall apart when sliced.
- Toss on the Topping:
- As the loaf is still warm, brush with melted butter. Mix sugar and cinnamon, then sprinkle over for a crunchy, sweet bite on top.
- Dive In:
- Cut into chunky slices. Eat it warm or leave it to cool off. Either way, your kitchen is going to smell incredible.

My favorite bit is swirling in the cinnamon sugar and seeing those fun ribbons when we slice it. The kids love brushing the butter on top then dousing it with sugar and cinnamon. It’s become our go-to baking project.
How to Keep It Fresh
Pop your cinnamon donut loaf in an airtight box on the counter. It’ll stay perfect for three days. Too warm in your kitchen or want to save it longer? Keep in the fridge up to a week. For freezing, wrap it tight in plastic and then foil after it’s cooled. Thaw on the counter for a few hours before you cut in.
Swap Options
No buttermilk? You can whip some up by adding a tablespoon of lemon juice or vinegar to milk and letting it sit for five minutes. You can also swap in applesauce for half the butter to keep it extra soft with less fat. If you want texture, mix in half a cup of walnuts or pecans when you add that last swirl.
Ways to Serve
This cinnamon donut bread holds its own, but it’s awesome with coffee or tea if you want a chill break. For dessert, heat a big slice and top it with vanilla ice cream or a little cream cheese icing. It also travels well—great for brunch buffets or wrapping up as a holiday gift.

This loaf nails the super soft, bakery donut vibe but skips all the frying. It smells just like those donut shops and brings back memories of cozy get-togethers and family weekends. With every slice, you get that sweet, cinnamony crunch—right at home.
