02 - Beat softened butter and dark brown sugar with an electric mixer until light and fluffy, approximately 2 minutes.
03 - Add egg, molasses, and vanilla extract to the creamed mixture and beat until fully combined.
04 - Gradually mix dry ingredients into the wet mixture until a soft dough forms.
05 - Divide dough in half, shape each into a disk, wrap in plastic wrap, and refrigerate for at least 1 hour or up to overnight.
06 - Preheat oven to 350°F. Line baking sheets with parchment paper.

09 - Once completely cooled, decorate with royal icing and sprinkles as desired.
