Tips
Use a cookie cutter to create fun shapes!
Use any pan you have - 9", multiple loaf pans, etc. It will change the thickness of the fudge.

How to Store Fudge
Room temperature in an airtight container up to a month.
Refrigerate in an airtight container. Bring to room temperature to enjoy.
Freeze wrapped in wax paper and sealed in a ziplock bag inside an airtight container to prevent freezer odor from seeping in. Freeze for up to 6 months. To thaw, simply remove the fudge from your freezer and bring it to room temperature before opening.
