Solskinnsboller – Norwegian Sun Buns (Solboller)
If you’ve been to a Norwegian bakery you’ve probably been overwhelmed by all the delicious cardamom and cinnamon buns on offer. There are traditional kanelboller, cardamom rolls, twisted kanelsnurrer, and of course the classic skolebrød. How are you to choose just one?
Lately I’ve found myself most often reaching for solskinnsboller, or “sunshine buns” in English, also called solboller, or “sun buns.”
Solskinnsboller are made with a sweet cardamom dough, rolled with cinnamon and sugar, filled in the center with vanilla custard, and drizzled with icing on top. Norwegians make many different kinds of custard buns, but solskinnsboller are some of the most popular Norwegian custard buns.
A solskinnsbolle is essentially a hybrid of a kanelbolle and skolebrød, without the coconut. In fact to make these, I used my kanelboller recipe and then added the vanilla custard and icing glaze from my skolebrød recipe.
Solskinnsboller might look intimidating to make because there are a lot of steps, but actually I think these are some of the easier Norwegian buns to make, because they’re pretty hard to mess up.
This is also why I like ordering them at bakeries. Kanelboller are more hit or miss, as sometimes they can be a bit dry if baked for too long, while skolebrød sometimes doesn’t have enough cardamom flavor in the dough.
But the vanilla custard in solskinnsboller keeps them from tasting too dry, and the cinnamon sugar swirl packs a lot of flavor into the dough. Win win!
Some Norwegians also call these buns solboller, but you don’t want to confuse them with the solboller Northern Norwegians eat when the sun returns after the polar night. Those solboller are more like doughnuts than buns. You can find my Northern Norwegian solboller recipe here.
Tips
Solskinnsboller dough has a lot of butter in it. And while usually it’s best to add butter to dough towards the end of kneading, in this case you should add in the melted (and cooled to room temperature) butter at the beginning.
Melt the butter into the milk in a saucepan and then remove it from the heat and pour the mixture into a large mixing bowl. Let it cool to lukewarm before adding the cardamom and yeast.
You can use ground cardamom for this recipe, but if you have a mortar and pestal I highly recommend grinding cardamom seeds instead, as freshly ground seeds are much more flavorful. If you only have ground cardamom, I would double the amount in the recipe.
You can knead the dough by hand or in a mixer with a dough hook. I knead it by hand for about ten minutes. The dough is quite easy to knead, so I really don’t think a mixer is necessary here, unless you have one you want to use. I usually just put on some music and enjoy the kneading!
While the dough is rising you can make the vanilla custard for the center of the buns.
Making the vanilla custard from scratch might seem intimidating, but it’s actually pretty easy. Just make sure that you keep whisking the custard the entire time you’re heating it so there aren’t any lumps. But if you don’t want to make it from scratch, you could simply use vanilla pudding instead.
Heat the milk and half of the sugar in a saucepan over medium heat. Split open the vanilla pod with a knife and carefully scrape out the seeds, adding them to the saucepan.
And in a separate bowl, mix together the rest of the sugar and the flour and corn starch. Add the egg yolks and whole egg and whisk it all together until it’s nice and smooth.
Once the milk starts to bubble in the saucepan, pour about half of it into the bowl with the egg mixture, whisking the entire time. Then return the saucepan to the heat and pour the egg and milk mixture from the bowl back into the saucepan, whisking the whole time.
Let the custard cook for 2 minutes, whisking the entire time. By the end it should be quite thick and harder to whisk.
Once the 2 minutes are up, remove the custard from the heat and pour it into a clean bowl. Cover with plastic wrap, placing it directly touching the top of the custard. Let the custard cool while the solskinnsboller dough finishes rising.
Make sure you put the plastic wrap directly onto the vanilla custard while it cools so that you don’t get a hard shell on top.
I like to roll the dough into a square, or even a tall rectangle, so that I can roll the dough many times, giving the kanelboller many spirals.
Make sure the butter is nice and soft when mixing it with the cinnamon and sugar, otherwise it will be hard to spread. If it isn’t soft you can pop it in the microwave for a few seconds.
If you like a very sweet cinnamon roll, you can add more sugar to the butter. You can also use brown sugar instead of white sugar, if you prefer.
When you spread the cinnamon sugar filling on the dough, make sure to keep a couple inches free on both the top and the bottom. This will make it easier to make a well in the middle of the bun for the vanilla custard, as the dough in the center of the roll won’t be full of butter and sugar.
I like to slice the buns quite thin, which gives a bit of a crispier solbolle.
When making the wells in the center of the rolls for the vanilla custard, make sure to press the dough down firmly, as the dough will puff up a bit again on the second rise. Also be sure the the bottom is in fact covered in dough – you don’t want to just make a hole through the whole roll, as then the custard will fall through.
Like skolebrød, I used to make solskinnsboller when I worked in the bakery section of a supermarket during my first year in Norway, and sometimes I would intentionally mess one up so that I could eat it. They’re just so irresistible! My kitchen still smells heavenly after baking these this morning. In fact it might be time for another one of these little sunshine cream buns…

Solskinnsboller – Norwegian Sun Buns (Solboller)
Equipment
- 1 Rolling Pin
- 1 small plastic bag for piping glaze
- 1 piping bag (optional)
Ingredients
Dough
- 2 cups milk
- 14 tbsp butter
- 1 cup powdered sugar
- 4 tsp instant yeast (or 50 g fresh yeast)
- 1 tsp cardamom
- 6 cups flour
Vanilla custard
- 2 cups milk
- 1/2 cup granulated sugar
- 3 egg yolks
- 1 egg
- 2.5 tbsp flour
- 1.5 tbsp corn starch
- 1 vanilla pod
Cinnamon filling
- 11 tbsp butter (softened)
- 6 tbsp sugar (white or brown)
- 1.5 tbsp cinnamon
Decoration
- 1 cup powdered sugar
- 1 tbsp water
- 1 egg (for egg wash)
Instructions
Dough
- Heat the milk, butter, and powdered sugar in a saucepan. Cool until just a bit warmer than lukewarm.
- Pour the milk mixture into a mixing bowl and add the cardamom and yeast. Stir until dissolved and then slowly add the flour. You may need more or less flour. Add enough so that you can knead the dough into a nice ball without being too sticky. Knead for about 10 minutes, then cover and let rise in a warm place until double in size (about an hour, possibly longer if using dry yeast).
Vanilla custard
- Heat the milk and half of the sugar in a saucepan. Split open the vanilla pod with a knife and carefully scrape out the seeds and add them to the milk.
- Mix together the rest of the sugar and the flour and corn starch in a bowl. Add the egg yolks and egg and whisk together until smooth.
- Once the milk mixture starts to bubble pour about half of it into the bowl with the egg mixture, whisking quickly the entire time. Then return the saucepan to the heat and pour the egg and milk mixture from the bowl back into the saucepan, whisking the whole time. Let the custard cook for 2 minutes, whisking the entire time. By the end it should be quite thick and harder to whisk.
- After 2 minutes remove the custard from the heat and pour into a clean bowl. Cover with plastic wrap, placing it directly touching the top of the custard. Let the custard cool while the dough finishes rising.
Filling
- Mix together the butter, sugar and cinnamon. If the butter is still hard you can pop it in the microwave for a few seconds so it's easy to spread.
- Roll out the dough into a large square. Spread the cinnamon butter mixture across all of the square, leaving a few centimeters (couple of inches) at the top and bottom of the square.
- Roll the rectangle from the bottom up into a long cylinder. Use a knife to cut (~1 inch) slices out of the cylinder. This should make about 22 buns. Set the buns spaced apart on baking sheets.
- Press down a large well in each bun. Be sure to press the dough all the way down and make a bigger well than you'll actually need, as the dough will puff back up a bit.
- Use a piping bag or spoon to place vanilla custard in the well of each bun (about 1- 2 tbsp of custard). Cover and let rise again for 30 minutes.
Baking & Decoration
- Preheat oven to 445°F (230°C). Whisk egg and carefully brush each bun with the egg wash (you can also skip this step). Bake the solskinnsboller for about 10 minutes, until golden brown.
- Cool buns on a wire rack. When the buns are fully cooled, mix together powdered sugar and water until you get a thick glaze. You can also add a couple spoons of the leftover egg whites (from the vanilla custard) to make the glaze extra white.
- Add the glaze to a small plastic bag and cut the tip off. Drizzle the buns with the glaze.

These were my favorite in Norway and they turned out great at home! I used 1 tbsp vanilla extract instead of a vanilla pod and the custard tasted great.

Very excited to make these! I’m assuming you use salted butter? Also, what are the storage instructions for these? Do these need to be refrigerated? I’ve never made anything with custard before so I’m unsure. Thanks in advance.

Yes, I use salted butter. I actually usually freeze them all and then when I’m ready to eat one I’ll pop it in the oven for a few minutes so it tastes freshly baked again. But you could also store them in the fridge if you think you’ll eat them within a week or so (you could also microwave them for 30 seconds to soften them a bit after being in the fridge). I keep them in a ziplock bag.

These turned out brilliantly and tasted delicious- definitely worth all the different stages. (I mistakenly made them because I was celebrating a bit more daylight but it was a happy mistake to make 😊)

If I wanted to make them the night before and cook them in the morning, would it be okay to put them in the fridge over night after filling with custard?

Yes, that should be fine. Cover them with plastic wrap and take them out of the fridge to let rise again at room temperature for 30 minutes before baking.

Wonderful recipe! Im Norwegian, and these taste just like the great sunshine buns I grew up with. I’ve baked them several times now, and they are a massive hit, everybody loves them. If I don’t have the vanilla bean pod, I substitute with 1 tbs of vanilla bean paste, and that works really well. THANK YOU SO MUCH for this recipe!
