In a microwave safe bowl melt your soap base in the microwave in 30-second intervals stirring in between. Should take around 5 minutes total to completely melt but microwave time may vary.

Carefully remove the soap base from the microwave and add in the fragrance oil and cinnamon (if using)

Pour the mixture into the gingerbread mold and let sit for 20 minutes or until fully hardened.

Carefully pop the gingerbread soap out of the mold. Can use right away or package for gift giving.
