Pretty much every home baker wants to make cinnamon buns. They smell wonderful and taste great. When I was in Sweden a couple of years ago I managed to have a few great Kanelbullar or cinnamon buns.
There are not a lot of recipes out there for Swedish Kanelbullar, so finding one that works was a bit of a task.
After a lot of searching I came across a recipe that seemed like it would work out well.

For this recipe I used:
For the Dough: 
750 Grams Pastry Flour
4.25 Teaspoons of Dry Yeast
75 Grams of Unsalted Butter
250 ml Whole Milk
60 ml Sugar
1 Pinch of Salt
1 Teaspoon Ground Cardamom

quick tip)

1 Large Egg
2 Teaspoons of Water
Pearl Sugar

| Kanelbullar - The Ingredients | 
Starting with the dough, I proofed the yeast in warmed (100˚F) Milk and a tablespoon of Sugar for 5 minutes. While the yeast was proofing I melted the butter in the microwave until just melted ans set it aside.
|  | 
| Kanelbullar - Proofing the Yeast | 
Once the yeast was proofed, I added the melted butter to a larger bowl then added the milk.

In the bowl of my 
mixer I added the flour, the balance of the sugar, and ground cardamom

With the mixer running on "2" I added the yeast mixture to the flour.

| Kanelbullar - Mixing the Dough | 
And let the mixer knead for 15 minutes. While the dough was kneading I heated my oven to 190˚F.

Once the mixer was finished I kneaded the dough on the counter for a couple of turns and returned the dough to the mixer bowl. 
|  |

I placed a tea towel over the bowl and put the bowl in the warmed oven and turned off the oven. I let the dough rise for about an hour.
|  | 
| Kanelbullar - Risen Dough | 
After the dough had risen I deflated it on my four covered counter.

Then rolled the dough out to about 25" wide by 12" tall.

In a 
medium bowl I mixed together the cinnamon and sugar.

Next I spread the room temperature butter over the dough and, as evenly as I could, I spread the cinnamon mixture over the butter.

I used my fingers to spread the cinnamon/butter out as evenly as I could.

Then I rolled up the cinnamon buns into a tight roll. It is best to avoid any air spaces when doing this.
|  | 
| Kanelbullar - Rolling into a Log | 
After rolling I cut the log up into 25 even pieces.

On a 
baking pan I laid out 24 parchment cupcake cups and placed a cinnamon roll on each cupcake liner.

I repeated on another baking pan with the rest of the pieces.

Of course before laying out the cupcake liners I missed putting a 
silpat on the empty baking pan. I covered the pans with a tea towel and placed the pan back into the oven for another hour of proofing.
|  | 
| Kanelbullar - Proofed | 
Once the Kanelbullar had proofed for an our I mixed the egg and water together creating an egg wash. 
|  |

I brushed the top of each bun with the egg wash and topped each bun with a few granules of pearl sugar. I also heated the oven to a very hot 480˚F!.

Once the oven was to temperature I baked the tray of buns. The recipe says 6-8 minutes. Mine took 9! I removed the pans from the oven and let the buns cool for about 10 minutes!

The bottoms were nicely browned and carmelised!

Bakers Notes:
- a pretty easy recipe
- my North American taste suggests I should add at least 1/2 teaspoon more of cardamom to the dough mixture
- these are best when eaten within a couple of hours of making them
- day old Kanelbullar are great when you split them and then use them as french toast
- Update May 2, 2015 - updated to use pastry flour instead of all-purpose flour
