There's something wonderful about taking a warm loaf of Cinnamon Swirl Donut Bread out of your oven. This treat brings together the yummy taste of classic cinnamon donuts in a soft, juicy bread that makes your house smell amazing. When you cut into it, you'll see beautiful cinnamon-sugar spirals running through each slice, making it look as good as it tastes.

I've baked this bread so many times for family breakfasts and holiday parties. One memory really stands out - I made it super early one Christmas and the smell slowly woke everyone up. They all wandered into the kitchen with big grins.

Must-Have Components

  • All-purpose flour: Go for unbleached kinds for extra goodness and a richer taste
  • Buttermilk: This magic ingredient gives you that authentic donut feel. It balances the sweetness just right
  • Canola oil AND butter: Together they keep your bread super juicy for several days
  • Pure vanilla extract: Worth spending a few extra bucks on the real stuff because you'll taste the difference
  • Ground cinnamon: Try to find Ceylon type if you can, its rich flavor really makes the bread special

Easy Preparation Guide

1. Get Everything Ready
Let your ingredients sit until they reach room temperature for better results
Put parchment in your bread pan with extra hanging over the sides for easy grabbing
Make sure your oven rack sits in the middle for even cooking
2. Combine The Basics
Beat your butter and sugar together for a full 5 minutes until it looks really fluffy
Put in eggs one by one, mixing well each time
Stir in your vanilla until everything looks smooth
3. Make Those Pretty Swirls
Pour half your plain mixture into the pan
Add spots of cinnamon mixture here and there
Gently drag a knife through to create pretty patterns without mixing too much
Do it all again with what's left of both mixtures
4. Bake It Just Right
Put your pan in the hot oven
Keep that oven door closed for at least 30 minutes
Look for slightly golden edges and a tiny crack on top
Stick a toothpick in - it should come out with a few wet crumbs
5. Add The Final Touches
Let it cool in the pan for 10 minutes exactly
Move it to a cooling rack
Brush some melted butter while it's still warm
Sprinkle lots of cinnamon sugar all over

When I was little, my grandma always told me cinnamon was the spice that makes you feel good inside. She'd put it on everything from her breakfast toast to her nighttime tea. Every time I bake this bread, those sweet memories come flooding back.

Ingredients

→ Base Layer

01 ¾ cup granulated sugar
02 2 tablespoons brown sugar
03 1 teaspoon baking powder
04 ½ cup buttermilk
05 ¼ cup unsalted butter, softened
06 1 ½ tablespoons vanilla extract
07 ¼ cup canola oil
08 ½ teaspoon salt
09 1 ½ cups universal flour
10 2 large eggs
11 ‌½ teaspoon molasses
12 1 teaspoon cinnamon powder

→ Cinnamon Coating

13 ¼ cup granulated sugar
14 ½ cup room-temp butter
15 ¼ cup light brown sugar
16 ½ teaspoon cinnamon

Instructions

Step 01

Heat your oven up to 350°F (175°C). Butter or spray a 9x5-inch loaf pan to keep things from sticking.

Step 02

In a bowl, stir together salt, baking powder, and flour. This mix is ready for action!

Step 03

Fire up your mixer! Whisk together softened butter, granulated sugar, and oil till it’s fluffy and smooth. A quick 3-minute mix does the trick.

Step 04

Crack in the eggs one by one, mixing well after each. Toss in that vanilla and give it another good stir.

Step 05

Slowly mix the wet and dry bowls, going in three steps. Start with the dry, drizzle some buttermilk, and keep alternating. Don’t mix too hard!

Step 06

Scoop a small bowl of batter (about ¾ cup) and combine it with all the cinnamon, brown sugar, and molasses. That’s your swirl magic.

Step 07

Pour half of the plain batter in your pan. Add blobs of half the cinnamon blend. Swirl it a little with a knife. Repeat with the rest.

Step 08

Bake for 45-50 mins. You’ll know it’s done if a toothpick comes out with just a few crumbs.

Step 09

Cool for 10 minutes. Coat it in melted butter and cinnamon-sugar on all sides. Chill fully before slicing it up.

Notes

  1. This treat is a cozy mix of sweet bread and cinnamon sugar donuts in one bite.
  2. Get perfect swirls by gently swirling the batter with a knife. Don’t overdo it!
