2 cups all-purpose flour
1 large egg white
1 tablespoon powdered sugar
0.5 teaspoon ground cinnamon

Steps
Preheat the oven to 375 degrees F (190 degrees C). Grease a cookie sheet.
Beat brown sugar, butter, and sweetener together in a bowl with an electric mixer until smooth. Add egg, vanilla, cinnamon, and baking powder; mix well. Gradually stir in flour; the mixture will be slightly sticky.
Flour your hands and roll and pinch dough into 18 logs; transfer to the prepared cookie sheet forming each log into a cinnamon roll shape.
Prepare cookie top coat: Put egg white in a small bowl. Mix powdered sugar, cinnamon, and sweetener together in a second bowl. Brush egg white on top of each cookie, then apply sugar topping.
Bake in the preheated oven for 7 minutes. Cookies will be slightly soft when they comes out; you want them like this. Let stand for 5 minutes.
Meanwhile, prepare icing: Mix 1 cup powdered sugar, 1 tablespoon milk, vanilla, and cinnamon in a pot over low heat. Stir until melted and combined; you can play with the consistency by adding more sugar or milk.
Drizzle icing over cookies and let sit for 3 minutes before serving.
