Make the filling by mixing the sugar, sesame seeds, and cinnamon powder in a bowl. Set aside.
Start the dough by combining water, sugar, dry yeast, kosher salt, and vegetable oil in a bowl. Mix well with a wooden spoon.
Add the flour and mix it well with the wooden spoon.
Knead the dough by hand for about 2 minutes, until it’s smooth. Let it sit for an hour, covered.
Uncover the dough and knead it another minute until it’s very smooth and soft.
Divide the dough into 4 equal size balls. Roll each into a nice smooth ball on the cutting board.
Cover the 4 balls with plastic wrap to prevent them from getting dried out while you work.
Make the bread
Put a non-stick baking pan into the oven and preheat the broiler.
Sprinkle some flour on the cutting board. Take one ball and roll it out with a rolling pin into a 4 inch disk. Add 1/4 of the filling in the center.
Lift up the right and left edges of the disc, bring them together, and pinch and seal them together. Then bring the top and bottom edges together too, to make a kind of dumpling.
Gently flatten and roll the disc out with your rolling pin, little by little, so as not to break it. Sprinkle some flour as needed so the dough, cutting board, and rolling pin don’t stick together.
Turn it over and roll it out carefully into a 5 1/2 to 6 inch disk.
Repeat with the rest of the dough balls.
Bake the bread
Your oven and the pan inside will be very hot. Change the oven setting from broil to bake. Put each bread disk on the heated pan in the oven.
Set the oven temperature to 350° F and bake it for 15 minutes.
Check out the color and crunchiness of the bread. If you want it darker and crispier, broil them for 1 minute more.
them cool down a bit and serve and eat. You can also freeze them up to 1 month.
