Winter "pulla" dough

"Winter" came and both my breads and buns started to look like.. something not to be so proud about.

They were goodish until they were warm, but as they cooled down they became hard and dry for my liking.
It needed to become more moist, more soft.. just more..
As a result, I decided to add a little bit more of everything: more butter, more egg yolk for richness, and a bit more milk to make a softer dough. Below you can see the recipe, and bake some for the cold winter nights, something to cuddle up with under your blanket with a mug of glögi.
Cozy blankets, hot drinks and soft buns, with some candles burning on the table.. Hmmm...

Ingredients
500 ml milk (2 cups), more towards 550 ml, lukewarm
3 tsp dry yeast
1 egg + 1 egg yolk
200 ml sugar (a bit less than 1/2 cups)
170 g butter (1 1/5 stick), melted
1 tsp or rather 1 tbsp minced cardamom seed
1 tsp salt
~950 g () all purpose (bread) flour
1 tsp vanilla sugar or the seeds of 1 vanilla bean (optional)
1 orange's or lemon's zest (optional), depends what goes better with your filling
1 tso or flat tbsp ground cardamom seeds


Proof the yeast in the lukewarm milk directly in your mixing bowl. Sprinkle it to the top of the milk, some sugar, mix lightly and let it sit for 5 minutes.
Add the sugar, egg+egg yolk, salt, vanilla, cardamom and orange zest. Start adding the flower gradually, mixing continuously.
Add about 80-90% of the flour, and let it mix in a smooth dough. Add the melted butter, gradually, mixing in small quantities of the leftover flour until all is well combined in a smooth dough.
It might still be sticking to the sided of the bowl, and it should be a very soft and moist dough.
Scrape the dough off the sided of the bowl, "wrap" it into a smooth ball, and place it back into a plastic bowl.
Cover with kitchen foil and a dry kitchen towel to keep both the moisture and warmth inside the bowl.
Let it sit for 1 - 1.5 hours, depending on the temperature of the house.
Divide the dough into three equal portions, form small balls, place them on a tray lined with parchment paper and cover with kitchen foil, and kitchen towel, and let it sit for additional 20 minutes or so. It should grow significantly again.
From here you'll continue to make your korvapuusti (cinnamon buns) or voisilmapulla, wreaths, or whatever bun you wish.
Bon appétit!
