Add all ingredients and knead on low speed, or knead by hand until dough forms, then add unsalted butter and knead until smooth.
Incubate the dough for the first time at normal temperature: for about 1 hour and the dough will double in size
Take the dough out and divide it into 8 equal parts, then let the dough rest for another 15 minutes and shape
After shaping, let the dough rest for the second time for about 30-45 minutes
Preheat the oven 15 minutes before baking, for example, when baking at 170 degrees, preheat the oven to 180 or 190 degrees because when opening the oven to put the cake in, the oven will lose a significant amount of heat. After putting the cake in, turn it back to 170 degrees
Spread the mixture before baking
When the cake is cooked, take it out while it is still hot and spread soft butter on the surface
