Preheat the oven to 350F. Also prepare a baking sheet by putting a sheet of parchment paper.
With a whisk, in a small bowl whisk the egg to brush the top of each cookie.
1 large egg
Divide the dough in half. Sprinkle some flour onto your surface where you can roll out the dough.
Take one half of the dough and gently roll it out into a rectangle shape. (If the dough is sticking to the surface, it means you are pushing too hard).
Sprinkle a generous amount of sugar throughout the rolled-out dough. (leave some for the other half of the dough and sprinkle on top of each cookie).
From the long side roll in the dough.
Cut into small pieces. (Remember, they will expand when baking). Put each piece onto the baking sheets and lightly push down each piece with two fingers to seal the open end.
Brush each cookie with a whisked egg, and sprinkle with sugar.
½ cup sugar
Repeat the process with the other half of the dough.
Place the cookies into the preheated oven and bake for 35-40 minutes or until golden brown.
