Line your baking sheets with parchment paper and preheat oven to 350F.
Cut the dough roll into even chunk. Shape and form into desired shape.
Arrange them onto baking sheet, make sure to leave some space, do not crowd as they will expand enormously.
For those with filling, just press your thumb in the middle to make a small indent (I used a tamper).
Spoon in jam onto each indent to fill each.
Bake for 13 minutes (soft cookie) or 15-17 minutes to brown state.
Once done baking, remove from oven and let sit as is for at least 10 minutes before transferring to cooling racks to avoid breaking.
For further decoration with icing, wait until your cookies is cool down to room temperature.
