Tips & Variations
- For a nuttier texture, add chopped peanuts to the mixture before refrigerating.
- You can substitute peanut butter chips with white or milk chocolate chips for a different flavor.
- Use parchment paper instead of foil if preferred, to prevent sticking.
Storage
Store the fudge covered in the refrigerator for up to one week. To soften before serving, let it sit at room temperature for about 10 minutes. You can also freeze fudge wrapped tightly for up to one month; thaw in the refrigerator before serving.

FAQs
Can I use crunchy peanut butter instead of chips?
Crunchy peanut butter won’t melt like chips, so it’s best to use peanut butter chips or smooth peanut butter melted with butter for the right consistency.
How do I prevent the marshmallows from burning?
Stir marshmallows in only after removing the pan from heat to prevent burning. The residual heat is enough to coat them without melting too much.
