Start with cookie dough, placing sugar on a food processor and grinding it for 10 seconds in high speed. Add butter, egg, vanilla extract, flour, baking soda, baking powder and salt; mix for 7 second
Roll dough to 16” by 8” rectangle with 1/6” thickness over a parchment paper. Mix cinnamon and sugar for your filling, until well combined; brush melted butter on top and sprinkle with sugar and cinnamon evenly on top
Roll your dough tightly until a big log is formed. With a sharp knife, start cutting 1 cm thick cookies, place them over the prepared baking sheets 1.5 inches apart and press slightly
Bake for 9-10 min, remove from the oven and let them cool slightly. Mix all your glaze ingredients and place them on a zip lock bag, snip a corner and drizzle your completely cooled cookie
