03 - Add the egg to the butter mixture and beat until combined, then stir in molasses and vanilla extract thoroughly.

05 - Divide dough into two portions, flatten each into a disk, wrap with plastic wrap, and refrigerate for at least 1 hour.
06 - Preheat oven to 350°F. Line baking sheets with parchment paper to prevent sticking.
07 - On a lightly floured surface, roll one dough disk to a thickness of 1/4 inch and cut into desired shapes using cookie cutters.
08 - Space cookies 1 inch apart on prepared baking sheets to allow for spreading during baking.
09 - Bake in preheated oven for 8 to 10 minutes, or until edges are set. Let cool on baking sheet for 5 minutes before transferring to wire rack.
10 - Once completely cooled, decorate cookies with royal icing and sprinkles or candies according to preference.
