FAQs
Can I make this fudge ahead of time?
Absolutely! You can prepare this fudge a few days in advance. Just store it properly according to the storage suggestions to keep it fresh.

How do I reheat fudge if it’s too hard?
Place it in the microwave for a few seconds at a time until it softens. Be sure to monitor it closely so it doesn’t melt completely.
