Melt shortening and peanut butter in a saucepan on the stove.
Pour melted shortening and peanut butter over dry mixture.
Stir with spoon until well combined.
Scoop warm mixture into plastic or silicone molds. Tuck in twine if you would like to hang them from their own loops or leave as is if planning to insert them into a suet cage. Freeze overnight. Remove from containers and hang outdoors.
