In a small bowl mix the lukewarm milk, yeast and sugar. Let the mixture foam for about 15 minutes.
In the meantime to a mixer with a dough hook, add all the ingredients, apart from the butter and mix together. Once you have a dough starting to form, start adding the butter piece by piece until it's all incorporated. Knead the dough for about 15 minutes.
Cover the dough and let it rest for an hour in the warmest place in your kitchen until it doubles in size.
Preheat the oven to 180°C or 350°F. Line a baking tray with parchment paper. Set aside.
Once the dough is ready, punch it down and knead for a couple of minutes. Divide the dough into 40 equal parts and form into balls.
Flatten each dough ball down and place a piece of cheese in the middle. Close the edges and roll into a bun.
Place the buns on the tray forming a Christmas tree. Before placing the buns into the oven, brush them with some milk.
Bake in the oven for about 20 minutes, until the buns have a nice golden brown colour.
In the meantime chop the parsley and mince the garlic. Combine them with the olive oil, chili flakes and a sprinkle of salt. Set aside.
Once baked, let them rest for a couple of minutes before brushing on top the garlic parsley oil. Enjoy!
