Defrost the phyllo dough. Now cut out a medium sized square out of the dough. Also coarsely grind the walnuts.
Mix the sugar and cinnamon powder with the walnuts and mix well. Now brush each phyllo sheet with butter and place one over another. Stack at least 7 to 10 sheets.
Now put the walnut mixture on the sheet of the lengthy side in a thick line leaving 1 inch of the sheet edge.
Next roll the sheet into a log shape. Cut carefully with a knife into small square or rectangles. Preheat the oven to 180 degree Celsius for 20 minutes.
Line a baking sheet and place these baklavas on the sheet and bake it on 165 degree Celsius for 20-25 minutes or till the below portions are lightly browned and the top part is crispy.
For the sugar syrup, mix sugar,water and rose water and bring it to boil. Boil till the syrup is slightly thickened.
Pour this syrup over the baked baklavas. It will take almost 2 to 3 hours for the baklavas to fully absorb the syrup.
After they have full absorbed the syrup, you can serve them to enjoy.
