1.In a measuring cup add milk then warm in the microwave. Add the yeast and mix, let it sit for 5 minutes.
2.Sift the flour into a large bowl then add the salt, and sugar. Mix well then add milk mixture and mix into a dough then cover the bowl with plastic wrap. Let it proof until the dough doubles in size, about 1 1/2 hours.
2.In a small bowl mix together dark brown sugar, cinnamon and walnuts. Set aside.
3.Release the gas by punching the dough with your hands a few times. Cover with the wrap again and let it rest for another 20 minutes. When the dough is ready, spray hands with cooking spray and separate the dough into 6 medium sized balls.
4.Put one piece of dough on your hand, flatten the dough with your hands so that you can add about 1 tablespoon of filling. Seal the dough by gathering the corners then pinching up into a ball. Repeat with the remaining dough.
5.Preheat a pan on medium heat and once it’s heated add 1 teaspoon oil and swirl it to coat the bottom evenly.
6.Place a dough into the pan and cook it on medium heat until the bottom side is lightly golden brown, about 30 seconds. Flip it over and press the dough down with a solid turner. Cook until the bottom part is golden brown, about 1 minute. Flip the pancake over one last time then reduce the heat to low. Cover the pan with a lid and cook until the sugar filing fully melts, about 1 minute.
7.Transfer the pancake onto a plate and repeat starting with adding another teaspoon of oil for the other dough balls. Enjoy hot!
